The methyl esters of carboxylic acids are characteristic olfactory volatile compounds for the sweet aroma of snake fruit, (Salacca edulis, Reinw) cv. Pondoh. Although methanol was not detected as a volatile constituent, the crude enzymes showed activity to synthesize the methyl esters in the presence of acyl-CoA and methanol. Therefore, the biosynthetic origin of methanol was investigated, resu...

Fast protein liquid chromatography (anion exchange) was used to separate glutathione S-transferase isozymes in nontreated etiolated maize shoots and those treated with the herbi­ cide safener CGA-154281 4-(dichloroacetyl)-3,4-dihydro-3-methyl-2 H-l ,4-benzoxazine. Non­ treated shoots contained isozymes active with the following substrates: fra/?s-cinnamic acid (1 isozyme), atrazine (3 isozymes)...

Thiopurine intolerance and treatment-related toxicity, such as fatal myelosuppression, is related to non-function genetic variants encoding thiopurine S-methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15). Genetic testing of the common variants NUDT15:NM_018283.2:c.415C>T (Arg139Cys, dbSNP rs116855232 T allele) and TPMT: NM_000367.4:c.719A>G (TPMT*3C, dbSNP rs1142345 G allele) in East Asia...

BACKGROUND 6-Mercaptopurine (6-MP) has confirmed short and longterm efficacy in the treatment of IBD. However, the relation between its metabolism, efficacy, and side effects is not well understood. AIMS To assay 6-MP metabolites and to correlate levels with drug compliance, disease activity, and adverse effects of treatment. PATIENTS Heparinised blood was obtained prior to daily administra...
