Abstract:
It is the embodiment of this invention to form novel compositions of Indoleamines e.g. 5-Hydroxytryptophan (5HTP) and/or Catecholamines e.g. L-Dopa with the gallocatechins e.g. (−)epigallocatechin3-O-gallate (EGCG) and/or (−) epigallocatechin (EGC) or any of the catechins found in green tea in a pharmaceutical or nutritional dosage or dietary regimen be it in tablet, liquid, capsule, injectable or any other ingestible form to achieve enhanced bioavailability and a superior safety profile.

Description:
[0001]     Supplementation of Serotonin (5-HT/5-Hydroxytryptamine) a key neurotransmitter into the Central Nervous System (CNS), has proved to be effective against many medical conditions, including but not limited to depression, obesity, fibromyalgia, myoclonus and others. 5-Hydroxytryptophan is decarboxylated to Serotonin via the ubiquitous enzyme L-Dopa Decarboxylase. To avoid premature decarboxylation several drugs i.e. Carbidopa and Benserazide have been employed as inhibitors of this enzyme. This is needed to ensure that the decarboxylation process occurs primarily after 5-HTP crosses the blood-brain barrier. Therefore, there will be greater safety and efficacy by minimizing the amount of circulatory Serotonin, which can have undesirable side-effects, and increasing the amount of Serotonin available in the CNS.  
         [0002]     In a similar fashion Levodopa effectively used for treatment of Parkinson&#39;s disease is combined with Carbidopa and/or Benserazide for similar purposes.  
         [0003]     We have been able to achieve the same effects using the non-pharmaceutical gallocatechins in place of Carbidopa and Benserazide. Surprisingly, in clinical trials we have achieved similar and in some cases superior results as measured by clinical markers and blood and urinary metabolites  
     
    
     DETAILED DESCRIPTION  
       [0000]     As a Supplement to the Brief Description Above We Have as Follows:  
         [0004]     This invention relates to a novel method for inhibiting the ubiquitious enzyme Aromatic Amino Acid Decarboxylase hereinafter referred to as (AADC) via non-pharmaceutical moieties  
         [0005]     The applications of said invention span a broad range, including but not limited to depression, Parkinson&#39;s disease, weight loss etc,  
         [0006]     The discussion and examples set forth herein with regard to 5-Hydroxytryptophan (5-HTP) can be analogously used with regard to L-Dopa  
         [0007]     The conversion of (5-HTP) to serotonin via (AADC) is shown in Diagram 1 To avoid its conversion to Serotonin in the periphery several pharmaceutical (s) have been found which in combination inhibit (AADC) so as to allow Serotonin conversion in the Central Nervous System (CNS) i.e. Carbidopa and Benserazide  
         [0008]     The galloatachins referred to in the abstract (−) epigallocatechin-3-O-gallate (EGCG) and/or (−) epigallocatechin (EGC) have such properties.  
         [0009]     Surprisingly in the two clinicals (Example 1 and 2 below) the combination showed superiority to the Pharmaceutical combinations in these respects 
        1. Lower Serotonin content in the circulatory system     2. Less side affects     3. Lower measured amounts of the key negative metabolic indicator 5-hydroxyindole acetic acid     4. Indications of a preferable metabolic time-profile consistent with the desired peripheral decarboxylation        
 
         [0014]     Example 1—10 subjects were given a tablet twice a day for five days containing 50 mg (5-HTP), 90 mg (EGCG)/(ECGC), 100 mg Tyrosine ang 100 mg Phenylalanine  
         [0015]     Example 2—Same as 1 but duration of dosaging was for 15 days!
