Ring Cleavage of Some Bicylic Compounds Derived from 1,2,4-Triazine
Ring cleavage occurred when 1,2,4-triazino-1,2,4-triazines (3), (4) and (5) were treated with concentrated hydrochloric acid to yield N-substituted triazines (7) and (8). These confirm the given configuration assigned to the isomeric triazinotriazines. 6-Methyl-2-phenyl-7H-oxazolo [3,2-b][1,2,4]-triazin-7-one (9) underwent ring cleavage on treatment with sodium alkoxide to afford 3-alkoxy-1...
متن کاملRole of epoxide hydrolases in lipid metabolism.
Epoxide hydrolases (EH), enzymes present in all living organisms, transform epoxide-containing lipids to 1,2-diols by the addition of a molecule of water. Many of these oxygenated lipid substrates have potent biological activities: host defense, control of development, regulation of blood pressure, inflammation, and pain. In general, the bioactivity of these natural epoxides is significantly re...

متن کاملRing dechlorination of deethylsimazine by hydrolases from Rhodococcus corallinus
Cell-free extracts of Rhodococcus corallinus NRRL B-15444R dechlorinated deethylsimazine (2-chloro-4-ethylamino-l,3,5-triazine-6-amine) to N-ethylammeline (2-amino-4-ethylamino-l,3,5-triazine-6(SH)-one) anaerobically, and, thus, presumably hydrolytically. Two enzyme fractions (M, about 450000 and 180000) that dechlorinated deethylsimazine were detected after gel permeation chromatography of cel...
متن کاملGene sequence and properties of an s-triazine ring-cleavage enzyme from Pseudomonas sp. strain NRRLB-12227.
Pesticides based on the s-triazine ring structure are widely used in cultivation of food crops. Cleavage of the s-triazine ring is an important step in the mineralization of s-triazine compounds and hence in their complete removal from the environment. Cyanuric acid amidohydrolase cleaves cyanuric acid (2,4,6-trihydroxy-s-triazine), which yields carbon dioxide and biuret; the biuret is subject ...
