COC1=CC2=C(C=CN=C2C=C1)[C@@H]([C@H]3C[C@@H]4CCN3CC4C=C)O.OS(=O)(=O)O | Please describe this drug. | Quinidine Sulfate is the sulfate salt form of quinidine, an alkaloid with antimalarial and antiarrhythmic (Class la) properties. Quinidine sulfate exerts its anti-malarial activity by acting primarily as an intra-erythrocytic schizonticide through association with the hemepolymer (hemozoin) in the acidic food vacuole of the parasite thereby preventing further polymerization by heme polymerase enzyme. This results in accumulation of toxic heme and death of the parasite. Quinidine sulfate exerts its antiarrhythmic effects by depressing the flow of sodium ions into cells during phase 0 of the cardiac action potential, thereby slowing the impulse conduction through the atrioventricular (AV) node, reducing the rate of phase 0 depolarization and prolonging the refractory period. Quinidine sulfate also reduces the slope of phase 4 depolarization in Purkinje-fibres resulting in slowed conduction and reduced automaticity in the heart. |

Upon administration, polaprezinc increases the expression of various anti-oxidant enzymes, such as superoxide dismutase 1 (SOD-1), SOD-2, heme oxygenase-1 (HO-1), glutathione S-transferase (GST), glutathione peroxidase (GSH-px), peroxidredoxin-1 (PRDX1; PRXI) and PRXD5 (PRXV) in the gastric mucosa, which protect cells against reactive oxygen species (ROS). In addition, this agent inhibits the activity of the transcription factor nuclear factor-kappaB (NF-kappaB) and reduces the expression of several pro-inflammatory cytokines, such as interleukin (IL) 1beta, IL-6, IL-8, and tumor necrosis factor alpha (TNF-a). Polaprezinc also increases the expression of various growth factors, such as platelet-derived growth factor-B (PDGF-B), vascular endothelial growth factor (VEGF), and nerve growth factor (NGF), and various heat shock proteins (HSPs), including HSP90, HSP70, HSP60, HSP47, HSP27, and HSP10.

Levalbuterol selectively binds to beta-2 adrenergic receptors in bronchial smooth muscle, thereby activating intracellular adenyl cyclase, an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP). Increased cAMP levels cause relaxation of bronchial smooth muscle, relieve bronchospasms, improve mucociliary clearance and inhibit the release of mediators of immediate hypersensitivity from cells, especially from mast cells. |

Gadofosveset is a stable gadolinium diethylenetriaminepentaacetic acid (Gd-DTPA) chelate derivative with a diphenylcyclohexylphosphate group. Upon injection, gadofosveset binds reversibly to endogenous serum albumin which increases its intravascular retention time compared to non-protein binding contrast agents. The serum albumin binding also increases T1-relaxivity of gadofosveset. This produces an increase in signal intensity of blood, thereby enhancing the visualization of blood vessels upon MRA and may aid in the diagnosis of certain blood vessels and heart disorders. |

Copper Cu 64 dotatate has a longer half-life and can be produced once a day as opposed to several times a day, and lower positron energy lending to improved spatial resolution. Further studies should be performed to compare the two tracers. Further, PET using Copper Cu 64 dotatate has been found to perform better than the current gold standard of single-photon emission computed tomography (SPECT) using 111In-DTPA-octreotide.

Upon intravenous administration, ceftolozane binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. This interferes with the final transpeptidation step required to form peptidoglycan chain cross-links, which are a key component of and provide strength and rigidity to the bacterial cell wall. This inhibits bacterial cell wall synthesis and reduces cell wall stability, which weakens the bacterial cell wall and causes bacterial cell lysis. Tazobactam irreversibly inhibits certain penicillinases and cephalosporinases and covalently binds to some chromosomal and plasmid-mediated bacterial beta-lactamases, thereby protecting ceftolozane from degradation and improving ceftolozane's activity. |
