     FIELD OF THE INVENTION 
     The present disclosure relates to compositions and methods for the enhancement of glutamate uptake, useful in the treatment of drug addiction, drug withdrawal, related conditions and diseases that involve modulation of glutamate uptake in their etiology such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM), Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain. 
     BACKGROUND OF THE INVENTION 
     Illicit drug use continues to be a major public health concern in the United States. According to the US Department of Health and Human Services&#39; 2009 National Survey on Drug Use and Health (US DDHS Report, 2009), an estimated 8.7% (21.8 million) of Americans age 12 or older reported being “current” illicit drug users, defined as having used a drug within one month of the survey. While the estimated number of American cocaine users age 12 or older has declined somewhat since 2006, it remains a major health concern, with approx. 16.7 million Americans (0.7% of the population) claiming to have used cocaine within a month of answering the survey. In addition, cocaine use is often seen as a complicating factor in cases of polyaddiction. There is a high prevalence of co-use of cocaine among heroin users (Leri et al., 2003). A high level of cocaine use has been shown to be an independent predictor of poor treatment outcome among heroin-dependent polydrug abusers (Downey et al., 2000). A degree of success in reducing heroin intake has been achieved through the use of opiate modulators such as methadone and buprenorphine (Stotts et al., 2009). However, studies suggest that the majority of cocaine/heroin abusers treated with methadone continued to use cocaine, even when the methadone reduced their heroin intake (Hartel et al., 1995; Magura et al., 1998). Thus, cocaine abuse represents a significant and complex health issue. 
     Addiction and recovery from addiction are characterized by a number of stages, each of which involves adaptations by various neurotransmitter systems (La Moel and Koob, 2007). In the early stages of the addiction process, the substance&#39;s ability to deliver reward plays a major role in drug use and continued use. As neuroadaptations take place over time, negative reinforcement augments the reward value of the drug, leading to dependence. Ultimately, when the drug is withdrawn after the establishment of dependence, a craving state occurs which can lead to relapse. Chronic exposure to cocaine induces marked alterations to the brain that make it difficult for many victims to withdraw from its use (Kreek and Koob, 1998; Bossert et al., 2005; Kreek et al., 2009). Dopaminergic signaling pathways play an important role in the reward learning and hedonic effects of cocaine abuse. However, several neurotransmitter systems may also be involved in addiction, including γ-aminobutyric acid (GABA), endocannabanoids, glutamate, endogenous opioids and serotonin (Goldstein and Volkow, 2002; Kalivas and Volkow, 2005). This complexity has made treatment of cocaine dependence a difficult goal to achieve. There are currently no FDA-approved medications for the treatment for cocaine addiction or withdrawal and there remains an urgent need for such medications (Van den Brink and van Ree, 2003; Kenna et al., 2007). 
     A number of marketed drugs and experimental agents targeting many of these neurotransmitter systems have recently entered clinical trials for the treatment of cocaine. Conventional efforts have targeted dopamine, serotonin, and norepinephrine systems. The strategy has resulted in the evaluation of at least 14 drugs as potential treatments (e.g. dopamine transporter inhibitors, L-DOPA, monoamine oxidase type B isozyme inhibitors, dopamine-releasing agents, dopamine D3 antagonists, 5-HT1A partial agonists, 5-HT reuptake inhibitors, etc.) (Vorel et al., 2002). Most of these agents produce adverse effects, including abuse liability, which limit their usefulness as abuse-deterrents. Other compounds being tested for cocaine addiction treatment are an anti-cocaine vaccine that retards entry of cocaine into the brain and a bacterial cocaine esterase that hydrolyzes cocaine into a nonpsychoactive metabolite (Ko et al., 2009; Kinsey et al., 2010). However, evidence that cocaine esterase has limited value in treating cocaine toxicity underscores the need to investigate alternative approaches (Shy et al., 2010). 
     Separately, Glioblastomas are malignant astrocytic tumors (WHO grade 4) and the most frequently occurring brain tumors. Disease prevalence is 1/100,000, and approximately 19,000 cases and 13,000 glioma related deaths are reported in the U.S. annually (Jemal, A., Siegel, R., Ward, E., Murray, T., Xu, J., Smigal, C. and Thun, M. J. CA Cancer J. Clin. 2006, 56, 106-130.) Glioblastomas can occur at any age, but 70% of cases occur in patients between 45 and 70. In addition, malignant gliomas are the most common solid cancer in children (Maher, C. O. and Raffel C. Pediatr. Clin. North Am. 2004, 51, 327-357). Survival time can be up to 5 years, but patients with glioblastoma multiforme (GBM), a deadly, invasive tumor, succumb to the disease within 6-12 months (Huncharek, M. and Muscat, J. Anticancer Res. 1998, 18, 1303-1311). The disease progresses rapidly (2-3 months) and symptoms resulting from intracranial hypertension are non-specific (headaches, vomiting, behavioral changes, neurological deficits), making diagnosis difficult. While there has been progress in developing new chemotherapeutic agents for many classes of cancer, there has been little progress towards the development of chemotherapeutic agents for malignant gliomas. Treatment options are limited, and often begin with surgery and biopsy to confirm diagnosis, but complete resection is rarely feasible, as tumor cells often infiltrate healthy brain tissue. Radiotherapy and chemotherapy can be employed, but the benefits from adjuvant treatments are modest as indicated by the minimal improvement in clinical outcomes using growth factor receptor antagonist treatments (EGFR, \PDGFR), mTOR inhibitors, AKT inhibitors, and PKC inhibitors((a) Adamson C, Kanu 00, Mehta A I, Di C, Lin N, Mattox A K, Bigner D. D. Expert Opin. Investig. Drugs 2009, 18:1061-1083. (b) Dresemann G. Ann Oncol 2005; 16:1702-1708, Reardon, D. A., Egorin, M. J., Quinn, J. A., J. Clin Oncol 2005, 23, 9359-9368). Unfortunately, tumor incidence has increased over the past 30 years (Jemal, A., Siegel, R., Ward, E., Murray, T., Xu, J., Smigal, C. and Thun, M. J. CA Cancer J. Clin. 2006, 56, 106-130) and prognosis is poor in the majority of cases (Azizi S. A. and Miyamoto C. J. Neurovirol. 1998, 4, 204-216). 
     Separately, Amyotrophic lateral sclerosis (ALS) is a debilitating disease characterized by the death of both upper and lower motor neurons in the motor cortex of the brain, the brain stem, and the spinal cord. This leads to diminished motor function, muscle wasting, and death in 3-5 years. The lifetime risk of developing ALS is 1 in 1,000, and there are approximately 35,000 patients in the US with ALS. The financial burden of ALS is significant with late stage ventilation treatment typically lasting up to 2 years at a cost of up to $400K per year. To date, Riluzole is the only medication approved for the treatment of ALS. The current standard of care is 50 mg of Riluzole daily and palliative drugs to address disease symptoms. The clinical efficacy of this therapy is limited, however, as it increases life expectancy by only 2-3 months after 15 months of treatment. 
     It has been demonstrated that nearly 75% of ALS patients have significantly decreased GLT-1 levels, which contributes to the rapid decline of patients via glutamate toxicity and neuronal cell death. Modulation of GLT-1 expression levels in ALS patients is an attractive target for therapeutic intervention in ALS. The SOD1 mouse model of ALS is based upon the decreased expression of GLT-1 in this strain of mouse. It has been demonstrated that ceftriaxone, a beta-lactam antibiotic, increases the expression of GLT-1 in the SOD1 mouse model of ALS, and this increase in GLT-1 increases the mean survival time of the SOD1 mouse through increased expression of GLT-1 (Rothstein, J. D.; Patel, S.; Regan, M. R.; Haenggeli, C.; Huang, Y. H.; Bergles, D. E.; Jin, L.; Hoberg, M. D.; Vidensky, S.; Chung, D. S.; Toan, S. V.; Bruijn, L. I.; Su, Z. Z.; Gupta, P; Fisher, P. B. Nature, 2005, 433, 73-77). Harmine, a beta-carboline alkaloid, also increases GLT-1 expression in the SOD1 mouse model of ALS (Li, Y.; Sattler, R.; Yang, E. J.; Nunes, A.; Ayukawa, Y.; Akhtar, S.; Ji, G.; Zhang, P. W; Rothstein, J. R. Neuropharmacology, 2011, 60, 1168-1175). Neither of these compounds has been approved for clinical uses as a treatment for ALS, and to date there are no modulators of glutamate uptake available for clinical use as treatments for ALS. 
     Separately, neuropathic pain is a collection of chronic conditions resulting from damage or dysfunction of the peripheral or central nervous system. More than 15 million people suffer from neuropathic pain in the US and Europe (American Chronic Pain Association). Symptoms can include dysesthesia, hyperesthesia, deep, aching pain, hyperalgesia, allodynia, parathesia, hyperpathia. Pain sensations reported in neuropathic pain conditions include burning, stabbing, aching and shooting as well as electric-shock, cold and “pins and needles”-like sensations. Neuropathic pain can be caused by a number of conditions, including physical trauma, stroke, diabetic neuropathy, nerve damage resulting from viral infection, amputation, chemotherapy, multiple sclerosis, cancer and alcoholism, Unlike normal nociceptive pain, neuropathic pain is not well managed by typical agents like opiate analgesics can anti-inflammatory agents. Currently available agents identified to target neuropathic pain such as antidepressants (duloxetine, venlafaxine, milnacipran, amytriptylene, desipramine) and antiepileptic agents (pregabilin, gabapentin, carbamazepine, oxycarbazepine) also provide limited relief. 
     Animal models have shown that neuropathic pain is associated with a decrease of glial GLT-1 expression (Ren, K.; Dubner. Curr. Opin. Anaesthesiol. 2008, 21, 570-579; Xin, W.-J.; Weng, H.-R.; Dougherty, P. Molecular Pain, 2009, 5, 15, doi:10.1186/1744-8069-5-15). A reduction in glutamate uptake activity results in an increase in synaptic glutamate concentrations, leading to neuronal hyperexcitability and hyperalgesia. Ceftriaxone, a beta-lactam antibiotic that upregulates GLT-1 expression, displays anit-nociceptive activity in a number of models of neuropathic pain (Hu, Y.; Li, W.; Lu, L.; Cai, J.; Xian, X.; Zhang, M.; Li, Q.; Li, L. Pain, 2010, 148, 284-301; Amin, B.; Hajhashemi, V.; Abnous, K.; Hosseinzadeh, H., Biomed. Res. Int. 2014, doi: 10.1155/2014/937568; Hajhashemi, V.; Hosseinzadeh, H.; Amin, B. Acta Neuropsychiatrica, 2012, 1, 27-32; Nicholson, K. J.; Gilliland, T. M.; Winkelstein, B. A., J. Neurosci. Res. 2014, 92, 116-129; Stepanovic, R. M.; Micov, A. M.; Tomic, M. A.; Kovacevic, J. M.; Boskovic, B. D. Anesthesiology 2014, 120, 737-750; Eljaja, L.; Bjerrum, O. J.; Honore, P. H.; Abrahamsen, B. Scandinavian J. Pain, 2011, 2, 132-136). 
     Separately, there is clinical and preclinical evidence that implicates dysregulation of glutamate (Glu) homeostasis in the development of Alzheimer&#39;s disease. Learning and memory are heavily dependent upon tight regulation of Glu neurotransmission, and disruption of this process can lead to increased synaptic Glu concentration, Glu-induced excitotoxicity, and neuron death (Grenamyre J T. Arch Neurol. 43; 1058-1063, 1986, Zadori D, et al. J Alzheim. Dis. 42 Suppl 3:S177-87, 2014. Mota S I, et al. Neuropharmacology. 2014 January; 76 Pt A:16-26, Paula-Lima A C, J. Neurochem. 126(2):191-202, 2013). The maintenance of Glu homeostasis is primarily dependent on transporters. The excitatory amino acid transporters (EAATs) are a family of proteins that remove Glu from the synapse via coupling the transport of Na +  and K +  down their concentration gradients, which drives Glu into the cell (Anderson C M, Swanson R A. Glia 32(1); 1-14, 2000). There are five EAATs in the mammalian nervous system, named EAAT1-5. Quantitative measurements of transporter densities (Furuta A, et al. J. Neurosci. 17; 8363-8375, 1997., Sims K, Crit. Rev. Neurobiol. 13; 169-197, 1999., Lehere K P, et al. J. Neurosci. 15; 1835-1853, 1995) and glutamate uptake (Rothstein J D, et al. Neuron 16(3); 675-86, 1996) indicate that EAAT1 (rodent GLAST) and EAAT 2 (rodent GLT-1) are the most abundant Glu transporters in brain tissue. Furthermore, GLT-1 is responsible for 90% of the total CNS Glu uptake. Importantly, GLT-1 activity is significantly reduced in early stage AD and the loss of GLT-1 correlates with cognitive decline (Kim K, et al. J. Cell Physiol. 226; 2484-2493, 2011. Volk L, et al. Annu. Rev. Neurosci. 38; 127-49, 2015). Further, decreased GLT-1 gene expression and protein levels have also been reported in the hippocampus of AD patients. These clinical observations suggest that changes in GLT-1 expression are related to Alzheimer&#39;s disease pathogenesis, and recent observation in transgenic mouse models support this hypothesis. Specifically, knockdown of GLT-1 in mice harboring two familial Alzheimer&#39;s disease mutations (AβPPswe and PS1ΔE9) significantly exacerbated cognitive decline, but Aβ pathology remained unchanged (13). 
     Separately, there is evidence implicating GLT-1 expression and glutamate dysregulation in epilepsy. Specifically, it has been demonstrated that mice that are homozygously deficient in GLT-1 are significantly more vulnerable to seizures and epilepsy (Tanaka, K. et. al. Science, 1609-1702). Further, these same studies demonstrated that these mice were prone to lethal spontaneous seizures as a result of decreased GLT-1 expression and loss of glutamate homeostasis in the brain. These findings suggest that restoration of GLT-1 expression and glutamate homeostasis may represent a novel approach to the treatment and prevention of epilepsy and seizure disorders. To date, however, there are no clinically useful therapies that apply this approach. 
     Separately, Cerebral Palsy (CP) is a non-progressive motor disorder that affects 1:300 live births annually within the United States alone. Even though it is classified as a motor disorder, it is caused by damage to the brain either in utero or within the first year after birth. Within the CP brain, there is conspicuous damage to the oligodendrocytes, the myelinating cells of the brain. This damage, known as Periventricular Leukomalacia (PVL), is a neurological hallmark seen in patients with CP. In addition to motor problems, cognitive deficits, ranging from mild to severe, also occur in over 75% of patients with CP. Current therapies for CP involve symptom management only, including mechanical braces, invasive spinal surgery and drugs to help treat spasticity and other negative motor symptoms. Although decades of research have focused on the white matter damage and subsequent neuronal cell loss in CP, little advancement has been made in understanding the cause or developing a cure. In fact, even with the major advances in neonatal medicine over the last 30 years, the incidence of CP remains unchanged. 
     Recent studies have implicated the excitatory amino acid neurotransmitter glutamate as an underlying cause of the brain damage seen in CP (Back et al., 2007; Khwaja and Volpe, 2008; Shen et al., 2010). During critical brain developmental periods, the neurons and oligodendrocytes in the brain are highly susceptible to glutamate toxicity, and these periods coincide with the time in which CP occurs in utero (Johnston and Hoon, 2006). Glutamate toxicity in CP cases is thought to be tied to an in utero loss of oxygen and blood flow (hypoxia-ischemia) to the fetal brain, mostly likely combined with, or due to an intrauterine infection or inflammation (Johnston and Hoon, 2006; Burd et al., 2009). Neurons in the neonatal brain also release excess glutamate, leading to glutamate toxicity and cell death. In principle, increased GLT-1 expression by either neurons or astrocytes would prevent the toxic build-up of glutamate by increasing synaptic glutamate clearance, but to date there are no clinically useful therapies capable of addressing this issue. To date, there are no treatment capable of preventing or treating CP. 
     There is a need in the art for compounds that modulate glutamate uptake and that may be useful in the treatment of diseases and disorders involved with glutamate uptake, such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM), Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain. The present invention addresses this need in the art.

     DETAILED DESCRIPTION OF THE INVENTION 
     There is a long felt need for new treatments of illicit drug addiction, drug withdrawal, and related conditions that are effective in treating patients for these conditions. There is also a long felt need for new treatments for diseases that involve modulation of glutamate uptake in their etiology such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM), Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain. The present invention addresses the need for new treatments of illicit drug addiction, drug withdrawal, and related conditions. The present invention also addresses the long felt need for new treatments for and means of preventing diseases that involve modulation of glutamate uptake in their etiology such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM), Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain. The beta lactams of the present invention are capable of treating drug addiction, withdrawal, related conditions and diseases that involve the modulation of glutamate uptake in their etiology such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM), Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain. 
     One neurotransmitter system that may have implications in addiction to multiple classes of illicit drugs is the glutamate system (Tzschentke and Wchmidt, 2003). Glutamate may be involved in many of the behaviors associated with addiction, and data suggest that dysregulation of glutamate homeostasis may play a significant role in the addiction process (Kalivas, 2009; Reissner and Kalivas, 2010). Chronic exposure to cocaine results in decreased levels of synaptic glutamate in the projections from the prefrontal cortex to the nucleus accumbens which, in turn, induces adaptive changes to the neurophysiology of the glutamatergic synapse (Schmidt and Pierce, 2010). The result of these changes is an impaired ability to regulate the increases in synaptic glutamate that occur in response to reinstatement of the drug, which may contribute to drug seeking and relapse. Among the changes that have been identified include down regulation of the cystiene-glutamate exchanger (xCT, the primary non-synaptic glutamate transporter) and GLT-1 (EAAT2, the primary synaptic glutamate transporter, located on astrocytes). It has been hypothesized that modulation of one or both of these transporter activities might stabilize cocaine-induced imbalance in glutamate homeostasis. Therefore, the cysteine-glutamate exchanger (xCT) and GLT-1 represent potential drug targets for treating cocaine craving and relapse. 
     Self-administration of cocaine by rats resulted in a reduction in both GLT-1 and cystine-glutamate exchanger expression. Until 2005, little pharmacological evidence existed that correlated GLT-1 enhancement with beneficial effects on cocaine dependence. Nakagura et al. (2005) showed that MS-153, a glutamate transport activator, inhibited the conditioned place preference induced by cocaine. However, the relevance of that data is compromised by the finding that MS-153 can also modulate glutamate release through its indirect activity on voltage-gated calcium channels (Uneishi et al., 1999). A blinded screen of 1,040 FDA-approved drugs and nutritionals identified the β-lactam antibiotic ceftriaxone (CTX) as a stimulator of GLT-1 expression (Rothstein et al., 2005; Lee et al., 2008). Ceftriaxone inhibits abstinence withdrawal from cocaine in a planarian model (Rawls et al., 2008), prevents relapse to cocaine seeking in rats and restores GLT-1 and cystine-glutamate exchanger levels that have been decreased by repeated cocaine administration (Sari et al., 2009; Knackstead et al., 2010). 
     The data with ceftriaxone suggests that a GLT-1 expression modulator could be useful for treating cocaine withdrawal. The data with ceftriaxone also suggests that a xCT expression modulator could be useful for treating cocaine withdrawal. However, ceftriaxone itself is not a suitable choice for this purpose. Ceftriaxone must be administered intravenously and a drug targeted at a chronic or sub-chronic indication such as cocaine withdrawal requires oral administration to enhance compliance. Further, because of its antimicrobial activity, chronic use of ceftriaxone presents a risk of inducing resistant strains of bacteria. Long term use of ceftriaxone can also result in debilitating side effects such as diarrhea, especially at the high doses required to achieve therapeutically meaningful CNS concentrations due to ceftriaxone&#39;s low brain bioavailability (free, unbound cerebrospinal fluid/plasma ratio=1% based on AUCs (Lutsar and Friedland, 2000) and 2-13% based on Cmax (Chadwick et al., 1983)). To date, there are no examples of orally bioavailable, CNS penetrant GLT-1 enhancer that are devoid of antibiotic activity and suitable for the chronic use required for the treatment of drug addiction, withdrawal, related conditions. 
     Dysregulation of Glu homeostasis may be responsible for GBM progression ((a) Sontheimer, H.  J. Neurochem.  2008, 105, 287-295. (b) de Groot, J. F., Liu, T. J., Fuller, G., and Yung, W. K. A.  Cancer Res.  2005, 65, 5, 1934-1940). Glu is the predominant excitatory amino acid neurotransmitter and GLT-1 is the dominant astroglial protein that inactivates synaptic Glu (Li, Y., Sattle, R., Eun Ju Yang, E. J., Nune, A., Ayukawa, Y., Sadia Akhtar, S., Grace Ji, G., Ping-Wu Zhang, P., Jeffrey D. Rothstein, J. D.  Neuropharmacology  2011, 60, 1168-1175). It is released through Ca 2+  dependent fusion of synaptic vesicles from activated neurons. Once released, Glu binds to a number of receptors/transporter systems that mediate biological responses. While Glu levels are normally tightly controlled, this is not the case in GBM. Normal Glu brain levels do not exceed 1-3 □M (Dzubay J. A. and Jahr C. E.  J Neurosci  1999, 19, 5265-5274), but studies of GBM patients using microdialysis probes to monitor brain Glu concentrations demonstrated Glu levels of &gt;100 □M at tumor margins ((a) Marcus, H., Carpenter, K., Price, S. J., Hutchinson P. J.  J. Neurooncol.  2010, 97, 11-23. (b) Roslin, M., Henriksson, R., Bergstrom, P., Ungerstedt, U., Bergenheim, A. T.  J. Neurooncol.  2003, 61, 151-160). GLT-1 is the key transporter that normnnally removes &gt;95% of synaptic Glu, but down regulation of its expression has been correlated with tumor grade, growth, and expansion (de Groot, J. F., Liu, T. J., Fuller, G., and Yung, W. K. A.  Cancer Res.  2005, 65, 5, 1934-1940). In addition to GLT-1 down-regulation, glioma cells demonstrate increased expression levels of glutamate-cystine exchanger system xc-, which increases glutamate release from glioma cells. The resulting high levels of Glu promote tumor growth and tissue invasion via excitotoxic cell death in the surrounding tissue creating space for tumor expansion within the restricted space of the cranial cavity (Sontheimer, H.  J. Neurochem.  2008, 105, 287-295). Further, Glu has been implicated in abnormal cell signaling processes controlling cell motility and invasion through autocrine mechanisms wherein Glu secreted from glioma cells activates signaling pathways responsible for cellular proliferative processes (MAPK: random migration, Akt: survival, invasion, FAK: cell migration) (Piao Y, Lu L, de Groot  J. Neuro Oncol  2009, 11:260-273). Interestingly, enhancing Glu transport by overexpressing GLT-1 in glioma cells in vitro and in vivo reduced cell proliferation and tumor growth in 2 independent studies ((a) de Groot, J. F., Liu, T. J., Fuller, G., and Yung, W. K. A.  Cancer Res.  2005, 65, 5, 1934-1940. (b) Vanhoutte, N., Quinones, J. A., Jordan, B. F., Gallez, B., Maloteaux, J. M. and Hermans, E.  Experimental Neurology,  2009, 218, 56-63), suggesting a significant role for GLT-1 in GBM. Specifically, de Groot et. al. transfected human glioblastoma cell lines U87, U373, SNB19, and U25 with a GLT-1 adenoviral vector in order to increase GLT-1 expression. A comparison of proliferation rates of Ad-GLT-1 cell lines with the standard gliobastoma cell lines demonstrated a clear time and expression level dependent decrease in cell proliferation. Further, subcutaneously implantation of Ad-GLT-1 U87 cells into nude mice were determined to be incapable of forming tumors, strongly suggesting that increased expression of GLT-1 leads to suppression of tumor formation (de Groot, J. F., Liu, T. J., Fuller, G., and Yung, W. K. A.  Cancer Res.  2005, 65, 5, 1934-1940). To date, there are no GLT-1 expression modulators available for the treatment of malignant glioma, glioblastomas and glioblastoma multiforme (GBM). 
     Loss of GLT-1 expression is an important aspect of early stage Alzheimer&#39;s disease pathology and may play a significant role in cognitive decline observed in patients. Further, up-regulation of GLT-1 expression may represent a novel approach to the treatment of Alzheimer&#39;s disease. 
     There is a long felt need for new treatments of illicit drug addiction, drug withdrawal, and related conditions that are effective in treating patients for these conditions. There is also a long felt need for new treatments for diseases that involve modulation of glutamate uptake in their etiology such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM), Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain. The present invention addresses the need for new treatments of illicit drug addiction, drug withdrawal, and related conditions. The present invention also addresses the long felt need for new treatments for and means of preventing diseases that involve modulation of glutamate uptake in their etiology such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM) Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain. 
     It has been discovered that compounds of the disclosure are capable of enhancing glutamate uptake. Without wishing to be limited by theory, it is believed that the beta lactams of the present inventions can ameliorate, abate, otherwise cause to be controlled drug addiction, drug withdrawal, related conditions, and diseases that involve modulation of glutamate uptake in their etiology such as amyotrophic lateral sclerosis (ALS), malignant glioma, glioblastomas, glioblastoma multiforme (GBM), Alzheimer&#39;s disease, cerebral palsy, epilepsy, and neuropathic pain.

     For the purposed of the present invention fused ring units, as well as spirocyclic rings, bicyclic rings and the like, which comprise a single heteroatom will be considered to belong to the cyclic family corresponding to the heteroatom containing ring. For example, 1,2,3,4-tetrahydroquinoline having the formula: 
     
       
         
         
             
             
         
       
     
     is, for the purposes of the present invention, considered a heterocyclic unit. 6,7-Dihydro-5H-cyclopentapyrimidine having the formula: 
     
       
         
         
             
             
         
       
     
     is, for the purposes of the present invention, considered a heteroaryl unit. When a fused ring unit contains heteroatoms in both a saturated and an aryl ring, the aryl ring will predominate and determine the type of category to which the ring is assigned. For example, 1,2,3,4-tetrahydro-[1,8]naphthyridine having the formula: 
     
       
         
         
             
             
         
       
     
     is, for the purposes of the present invention, considered a heteroaryl unit. 
     Whenever a term or either of their prefix roots appear in a name of a substituent the name is to be interpreted as including those limitations provided herein. For example, whenever the term “alkyl” or “aryl” or either of their prefix roots appear in a name of a substituent (e.g., arylalkyl, alkylamino) the name is to be interpreted as including those limitations given above for “alkyl” and “aryl.” 
     The term “substituted” is used throughout the specification. The term “substituted” is defined herein as a moiety, whether acyclic or cyclic, which has one or more hydrogen atoms replaced by a substituent or several (e.g., 1 to 10) substituents as defined herein below. The substituents are capable of replacing one or two hydrogen atoms of a single moiety at a time. In addition, these substituents can replace two hydrogen atoms on two adjacent carbons to form said substituent, new moiety or unit. For example, a substituted unit that requires a single hydrogen atom replacement includes halogen, hydroxyl, and the like. A two hydrogen atom replacement includes carbonyl, oximino, and the like. A two hydrogen atom replacement from adjacent carbon atoms includes epoxy, and the like. The term “substituted” is used throughout the present specification to indicate that a moiety can have one or more of the hydrogen atoms replaced by a substituent. When a moiety is described as “substituted” any number of the hydrogen atoms may be replaced. For example, difluoromethyl is a substituted C 1  alkyl; trifluoromethyl is a substituted C 1  alkyl; 4-hydroxyphenyl is a substituted aromatic ring; (N,N-dimethyl-5-amino)octanyl is a substituted C 8  alkyl; 3-guanidinopropyl is a substituted C 3  alkyl; and 2-carboxypyridinyl is a substituted heteroaryl. 
     The variable groups defined herein, e.g., alkyl, alkenyl, alkynyl, cycloalkyl, alkoxy, aryloxy, aryl, heterocycle and heteroaryl groups defined herein, whether used alone or as part of another group, can be optionally substituted. Optionally substituted groups will be so indicated.

     At various places in the present specification, substituents of compounds are disclosed in groups or in ranges. It is specifically intended that the description include each and every individual subcombination of the members of such groups and ranges. For example, the term “C 1-6  alkyl” is specifically intended to individually disclose C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 1 -C 6 , C 1 -C 5 , C 1 -C 4 , C 1 -C 3 , C 1 -C 2 , C 2 -C 6 , C 2 -C 5 , C 2 -C 4 , C 2 -C 3 , C 3 -C 6 , C 3 -C 5 , C 3 -C 4 , C 4 -C 6 , C 4 -C 5 , and C 5 -C 6 , alkyl. 
     For the purposes of the present invention the terms “compound,” “analog,” and “composition of matter” stand equally well for the beta lactams described herein, including all enantiomeric forms, diastereomeric forms, salts, and the like, and the terms “compound,” “analog,” and “composition of matter” are used interchangeably throughout the present specification. 
     Compounds described herein can contain an asymmetric atom (also referred as a chiral center), and some of the compounds can contain one or more asymmetric atoms or centers, which can thus give rise to optical isomers (enantiomers) and diastereomers. The present teachings and compounds disclosed herein include such enantiomers and diastereomers, as well as the racemic and resolved, enantiomerically pure R and S stereoisomers, as well as other mixtures of the R and S stereoisomers and pharmaceutically acceptable salts thereof. Optical isomers can be obtained in pure form by standard procedures known to those skilled in the art, which include, but are not limited to, diastereomeric salt formation, kinetic resolution, and asymmetric synthesis. The present teachings also encompass cis and trans isomers of compounds containing alkenyl moieties (e.g., alkenes and imines). It is also understood that the present teachings encompass all possible regioisomers, and mixtures thereof, which can be obtained in pure form by standard separation procedures known to those skilled in the art, and include, but are not limited to, column chromatography, thin-layer chromatography, and high-performance liquid chromatography. 
     Pharmaceutically acceptable salts of compounds of the present teachings, which can have an acidic moiety, can be formed using organic and inorganic bases. Both mono and polyanionic salts are contemplated, depending on the number of acidic hydrogens available for deprotonation. Suitable salts formed with bases include metal salts, such as alkali metal or alkaline earth metal salts, for example sodium, potassium, or magnesium salts; ammonia salts and organic amine salts, such as those formed with morpholine, thiomorpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine (e.g., ethyl-tert-butyl-, diethyl-, diisopropyl-, triethyl-, tributyl- or dimethylpropylamine), or a mono-, di-, or trihydroxy lower alkylamine (e.g., mono-, di- or triethanolamine). Specific non-limiting examples of inorganic bases include NaHCO 3 , Na 2 CO 3 , KHCO 3 , K 2 CO 3 , Cs 2 CO 3 , LiOH, NaOH, KOH, NaH 2 PO 4 , Na 2 HPO 4 , and Na 3 PO 4 . Internal salts also can be formed. Similarly, when a compound disclosed herein contains a basic moiety, salts can be formed using organic and inorganic acids. For example, salts can be formed from the following acids: acetic, propionic, lactic, benzenesulfonic, benzoic, camphorsulfonic, citric, tartaric, succinic, dichloroacetic, ethenesulfonic, formic, fumaric, gluconic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, malonic, mandelic, methanesulfonic, mucic, napthalenesulfonic, nitric, oxalic, pamoic, pantothenic, phosphoric, phthalic, propionic, succinic, sulfuric, tartaric, toluenesulfonic, and camphorsulfonic as well as other known pharmaceutically acceptable acids. 
     When any variable occurs more than one time in any constituent or in any formula, its definition in each occurrence is independent of its definition at every other occurrence (e.g., in N(R 7 ) 2 , each R 7  may be the same or different than the other). Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. 
     The terms “treat” and “treating” and “treatment” as used herein, refer to partially or completely alleviating, inhibiting, ameliorating and/or relieving a condition from which a patient is suspected to suffer. 
     As used herein, “therapeutically effective” and “effective dose” refer to a substance or an amount that elicits a desirable biological activity or effect. 
     Except when noted, the terms “subject” or “patient” are used interchangeably and refer to mammals such as human patients and non-human primates, as well as experimental animals such as rabbits, rats, and mice, and other animals. Accordingly, the term “subject” or “patient” as used herein means any mammalian patient or subject to which the compounds of the invention can be administered. In an exemplary embodiment of the present invention, to identify subject patients for treatment according to the methods of the invention, accepted screening methods are employed to determine risk factors associated with a targeted or suspected disease or condition or to determine the status of an existing disease or condition in a subject. These screening methods include, for example, conventional work-ups to determine risk factors that may be associated with the targeted or suspected disease or condition. These and other routine methods allow the clinician to select patients in need of therapy using the methods and compounds of the present invention.

     Process 
     The present invention further relates to a process for preparing the beta lactams of the present invention. 
     Compounds of the present teachings can be prepared in accordance with the procedures outlined herein, from commercially available starting materials, compounds known in the literature, or readily prepared intermediates, by employing standard synthetic methods and procedures known to those skilled in the art. Standard synthetic methods and procedures for the preparation of organic molecules and functional group transformations and manipulations can be readily obtained from the relevant scientific literature or from standard textbooks in the field. It will be appreciated that where typical or preferred process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions can vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures. Those skilled in the art of organic synthesis will recognize that the nature and order of the synthetic steps presented can be varied for the purpose of optimizing the formation of the compounds described herein. 
     The processes described herein can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g.,  1 H or  13 C), infrared spectroscopy, spectrophotometry (e.g., UV-visible), mass spectrometry, or by chromatography such as high pressure liquid chromatograpy (HPLC), gas chromatography (GC), gel-permeation chromatography (GPC), or thin layer chromatography (TLC). 
     Preparation of the compounds can involve protection and deprotection of various chemical groups. The need for protection and deprotection and the selection of appropriate protecting groups can be readily determined by one skilled in the art. The chemistry of protecting groups can be found, for example, in Greene et al.,  Protective Groups in Organic Synthesis,  2d.  Ed . (Wiley &amp; Sons, 1991), the entire disclosure of which is incorporated by reference herein for all purposes. 
     The reactions or the processes described herein can be carried out in suitable solvents which can be readily selected by one skilled in the art of organic synthesis. Suitable solvents typically are substantially nonreactive with the reactants, intermediates, and/or products at the temperatures at which the reactions are carried out, i.e., temperatures that can range from the solvent&#39;s freezing temperature to the solvent&#39;s boiling temperature. A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected. 
     The compounds of these teachings can be prepared by methods known in the art of organic chemistry.

     Primary Cortical Astrocyte Cultures: 
     Astrocyte cultures were prepared according to previously established protocols (Aschner et al. 1992). Astrocytes were isolated from cerebral cortices of newborn (1-day-old) Sprague-Dawley rats. Pups were decapitated under halothane-anesthesia, and the cerebral cortices were dissected out. The meninges were removed, and the cortices were digested with bacterial neutral protease (Dispase, Invitrogen, Eugene, Oreg., USA). Astrocytes were then recovered by the repeated removal of dissociated cells and plated at a density of 1×10 5  cells/mL. Twenty-four hours after the initial plating, the media were changed to preserve the adhering astrocytes and to remove neurons and oligodendrocytes. The cultures were maintained at 37° C. in a 95% air/5% CO 2  incubator for 3 weeks in minimum essential medium (MEM) with Earle&#39;s salts supplemented with 10% fetal bovine serum, 100 U/mL of penicillin and 100 μg/mL of streptomycin. The media were changed twice per week. The purity of these cultures was &gt;95%-positive for the astrocyte-specific marker, glial fibrillary acidic protein. 
     Glutamate Uptake Assay: 
     Glutamate uptake was measured as previously described (Mutkus et al. 2005), with a minor modification. Astrocytes (24-well plates) were treated with compounds in Opti-MEM reduced serum media for 30 minutes. Next, the culture media were washed 2× and replaced with the uptake buffer, pre-warmed HEPES-buffered solution containing 122 mM NaCl, 3.3 mM KCl, 0.4 mM MgSO 4 , 1.3 mM CaCl 2 , 1.2 mM KH 2 PO 4 , 25 mM HEPES, and 10 mM D-(+)-glucose, pH of 7.4. Five min later, pre-warmed uptake buffer containing 0.25 μCi/ml L-[ 3 H]-glutamate (specific activity: 49.0 μCi/mmol, Amersham Pharmacia Biotech, Piscataway, N.J., USA) and unlabeled glutamate at a final concentration of 100 nM (Liang et al. 2002) was added. Uptake was terminated after 10 minutes of incubation at 37° C. by three washes with ice-cold PBS, immediately followed by cell lysis in 1 mL of 1 N NaOH. An aliquot of 750 μL was neutralized in 75 μL of 10 N HCl, and radioactivity was determined by liquid scintillation counter (LS 6500, Beckman Coulter, Fullerton, Calif., USA). Protein content was determined using a 25 μL aliquot neutralized in 1 N HCl, and quantified using the bicinchoninic acid protein assay reagent kit (Pierce, Rockford, Ill., USA). Radioactivity counts were corrected for protein levels and calculated as glutamate nmol/mg protein/minute. Experiments were performed in quadruplicates in three independent cultures. 
     Measurement of the Extracellular L-Glutamate Concentrations 
     A series of experiments was carried out to determine the rate of glutamate disappearance from the media as a surrogate measure of glutamate uptake in astrocytes. Extracellular glutamate levels were measured by a fluorimetric method, using the Amplex Red Glutamic Acid assay kit (Invitrogen). Cells in 96-well plates were treated with Mn, E2 or TX in Opti-MEM media for the indicated times. Immediately thereafter, the uptake buffer containing glutamic acid (20 μM) was replaced with media in each well. After 30 minutes of incubation, 50 μL of supernatants from each sample was transferred into 96-well plates, followed by the addition of 50 μL of substrate mixture containing 100 μM Amplex Red, 0.25 U/mL horseradish peroxidase, 0.08 U/mL L-glutamate oxidase, 0.5 U/mL L-glutamatepyruvate transaminase, 200 IM L-alanine and 1⋅ reaction buffer. After 30 min of incubation at 37° C., fluorescence was measured in a fluorescence microplate reader (FlexStation, Molecular Devices, Sunnyvale, Calif., USA) with excitation-emission at 530-590 nm. 
     Primary Neuron-Astrocyte Co-Culture 
     Primary astroglial cells were cultured from postnatal 2-3 days mouse pups. Cortices were dissected out and dissociated with papain and subsequently cultured on collagen-coated T75 flask in DMEM containing 10% fetal bovine serum (FBS). At DIV14 astrogial cells were seeded into collagen-coated 6-well plates at a concentration of 7×10 5  cells/well. Primary cortical neurons were isolated from cortices of E16 embryonic mice. After dissociated with papain, 1 million neurons were seeded per well on the top of the confluent astrocytes. Co-cultures were first maintained in Neurobasal medium supplemented with 5% FBS and 2% B-27. After 4 days half of the medium was changed into serum free Neurobasal medium supplemented with 2% B27. Cells were treated with compounds of the disclosure at DIV5 for 3-6 days accordingly. 
     In Vitro Screen for GLT-1 Uptake Activity in Primary Neuron-Astrocyte Co-Culture: 
     0.5 μM L-glutamate (cold:radioactive=99:1) and 0.3 μCi L-[ 3 H]glutamate per sample (PerkinElmer) are used for measuring glutamate uptake in mixed neuron-astrocyte cultures. Cells are first washed and pre-incubated at room temperature for 10 minutes in Na +  buffer (5 mM Tris-HCl, pH 7.2, 10 mM HEPES, 140 mM NaCl, 2.5 mM KCl, 1.2 mM CaCl 2 , 1.2 mM MgCl 2 , 1.2 mM K 2 HPO 4 , and 10 mM D-glucose) in the presence or absence of compounds of the disclosure. Glutamate uptake reaction is started by incubating cells for 5 minutes at 37° C. in Na +  buffer containing 0.5 μM L-glutamate and 0.3 μCi L-[ 3 H] glutamate per sample, followed by rapid washing twice with ice-cold Na + -free assay buffer (5 mM Tris-HCl, pH 7.2, 10 mM HEPES, 140 mM Choline-Cl, 2.5 mM KCl, 1.2 mM CaCl 2 , 1.2 mM MgCl 2 , 1.2 mM K 2 HPO 4 , and 10 mM D-glucose). Cells are then lysed with 0.1N NaOH solution and radioactivity is measured using a scintillation counter. Protein concentrations is measured from the cell lysate using the Bradford method. Uptake data is normalized to total protein. 
     In Vitro Screen for XCT Activity: 
     U87 human glioblastoma-astrocytoma cells (ATCC number HTB14) were seeded at 0.067×10 6  cells per well and grown to confluency in 12-well plates for 6 days. On the day of the experiment, the cells were washed with pre-warmed (37° C.) sodium free uptake buffer (contents in mM: choline chloride 137.5, KCl 5.36, KH 2 PO 4  0.77, MgSO 4  0.71, CaCl 2  1.1, Glucose 10 and HEPES 10, pH 7.4) and incubated at 37° C., for 15 minutes using 80 μM L-[ 14 C(U)]-cystine and at a specific activity of 1.35 μCi/lmol in the presence and compounds of the disclosure. L-[ 14 C(U)]-cystine uptake was terminated by three washes with ice-cold uptake buffer. Subsequently, cells were lysed with 0.1 N NaOH and the radioactivity in the cells measured using a liquid scintillation counter and the counts normalized to the protein contents. The data were then normalized to the ‘totals’ (uptake at 37° C. in the absence compounds of the disclosure) and ‘blanks’ (uptake at 0° C. in the absence of compounds of the disclosure) and presented as percent inhibition ((1-(Unknown-blanks)/(totals-blanks))×100). Subsequently, the inhibitory constant at 50% inhibition (IC 50 ) was calculated using GraphPad Prism. 
     Rat Screening with Cocaine for GLT-1 Activity: 
     Rats were trained to self-administer intravenous cocaine (n=14) in a standard 2-lever operant chamber where each press on the active lever yielded delivery of 0.25 mg cocaine and the presentation of drug-paired cues: a stimulus light above the lever and a tone (4900 Hz). Animals underwent 12 sessions of cocaine self-administration, with a requirement of a minimum of 10 infusions attained per session. A control group (SAL; n=7) received saline infusions when their cocaine counterpart received cocaine. Following the self-administration (or yoked-saline) portion of the experiment, animals underwent extinction training, during which time presses on the previously active lever no longer resulted in cocaine or cue delivery. Animals went through extinction training for 3 weeks. For the last 6 days of extinction training (prior to sacrifice) a subset of the cocaine animals (Coc-MC; n=7) was treated with compounds of the disclosure (I.P. dosing) while the remaining subset (Coc-Veh; n=7) were injected with vehicle (sterile water; 0.3 mL). Animals were sacrificed, the nucleus accumbens core was dissected and processed to isolate a membrane-enriched fraction. Proteins were separated using 10% SDS-PAGE and transferred to PVDF membrane. The membranes were blocked in 3% milk and probed overnight at 4° C. with primary antibody against GLT-1 (1:1000, Chemicon). Membranes were washed with TBS-Tween-20 and incubated with secondary antibody at room temperature. After visualization (Pierce Western Mouse Pico Kit) band density was measured with NIH Image J software. The membranes were then re-blotted for calnexin (1:20,000; Stressgen), an endoplasmic reticulum protein used to control for the amount of protein loaded in each lane. The immunoreactivity of each GLT-1 band was normalized to calnexin and the averages within each treatment group were compared.
