Pyrimethamine

5-(4-Chlorophenyl)-6-ethyl-2,4-pyrimidinediamine

C12H13ClN4 (248.0828688)

Pyrimethamine is only found in individuals that have used or taken this drug. It is one of the folic acid antagonists that is used as an antimalarial or with a sulfonamide to treat toxoplasmosis. [PubChem]Pyrimethamine inhibits the dihydrofolate reductase of plasmodia and thereby blocks the biosynthesis of purines and pyrimidines, which are essential for DNA synthesis and cell multiplication. This leads to failure of nuclear division at the time of schizont formation in erythrocytes and liver.

Allithiamine is found in chives as well as garlic (Allium sativum). It imparts a meaty flavour to foods. Allithiamine has vitamin B1 activity. It has been investigated as a dietary supplement to enhance muscle performance in sports. Allithiamine is a lipid-soluble form of vitamin B1 which occurs naturally in garlic. It is more bioavailable than the water-soluble form of vitamin B1, thiamine, and is the preferred form to be taken in case of a vitamin deficiency.[citation needed obtained from garlic (Allium sativum). Imparts meaty flavour to foods. Has vitamin B1 activity. Investigated as a dietary supplement to enhance muscle performance in sports [DFC]

2-O-Methylcytosine

C5H7N3O (125.0589092)

O-2-Methylcytosine is a 2-O-methylated nucleotide residue. Naturally occurring modified residues derived from canonical RNA nucleotides are present in most cellular RNAs; their detection is difficult because of their great diversity and their irregular distribution within RNA molecules. Human ribosomes contain more than 200 modified nucleotides; of these more than 100 are 2-O-methylated. (PMID: 17673078, 7599273) [HMDB] O-2-Methylcytosine is a 2-O-methylated nucleotide residue.

DGAT-1 inhibitor 2 is an effective inhibitor of DGAT-1;antiobesity agents. IC50 value: Target: DGAT-1 Acyl-CoA:diacylglycerol acyltransferase 1 (DGAT1) is one of two known DGAT enzymes that catalyze the final step in triglyceride synthesis. Findings from genetically modified mice as well as pharmacological studies suggest that inhibition of DGAT1 is a promising strategy for the treatment of obesity and type 2 diabetes.

4-amino-2-methyl-5-phosphomethylpyrimidine, also known as hmp-P, belongs to aminopyrimidines and derivatives class of compounds. Those are organic compounds containing an amino group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 4-amino-2-methyl-5-phosphomethylpyrimidine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). 4-amino-2-methyl-5-phosphomethylpyrimidine can be found in a number of food items such as chives, chestnut, common hazelnut, and lupine, which makes 4-amino-2-methyl-5-phosphomethylpyrimidine a potential biomarker for the consumption of these food products.
