The properties relevant to pharmacokinetics and pharmacodynamics of four series of synthesized s-triazine derivatives have been studied by Quantitative structure-retention relationship (QSRR) approach. The chromatographic behavior of these compounds was investigated by using reversed-phase high performance thin-layer chromatography (RP-HPTLC). Chromatographic retention (RM0) was correlated with...

In this paper we present the convenient syntheses of seven new phenyl hydrazin derivatives 8 (a-h). For this purpose, acenaphtho [1,2-e]-1,2,4-triazine-9(8H)-thione (3) was prepared, starting from acenaphthylene-1, 2-dione (1) and thiosemicabazide in good yield. The reaction of (3) with benzyl chloride resulted to synthesis of 9-(benzylthio)-acenaphtho[1,2-e]-1,2,4-triazines (5) that reacted wi...

The reaction of the cyanoacetylhydrazine (1) with α-bromoketones (2a-c) gave the hydrazide-hydrazone derivatives 3a-c. The latter compounds underwent ready cyclization when heated in sodium ethoxide to form the 1,3,4-oxadiazine derivatives 4a-c. The reaction of 3a with hydrazines gave the 1,3,4-triazine derivatives 7a,b. Compounds 3a-c and 7a,b underwent some heterocyclizations when treated wit...

Synthesis of 2,3- and 3,4-cyclopentenopyridines, 5,6,7,8-tetrahydroquinolines and 5,6,7,8-tetrahydroisoquinolines from 1,2,4-triazine derivatives is reported. Introduction of an alpha-functionalized methyl substituent (e.g. arylsulphonyl, sulphonamide, sulphonic acid ester) into position 3- or 6- of triazines by vicarious nucleophilic substitution of hydrogen and subsequent alkylation with alky...

An effective and highly regio- and diastereoselective one-pot method for the synthesis of new polynuclear dispiroheterocyclic systems with five stereogenic centers (dispiro[imidazo[4,5-e]thiazolo[3,2-b]-1,2,4-triazine-6,3'-pyrrolidine-2',3''-indoles]) comprising pyrrolidinyloxindole and imidazo[4,5-e]thiazolo[3,2-b]-1,2,4-triazine moieties has been developed. The method relies on a 1,3-dipolar ...

introduction: increased oxidative stress is widely accepted to be a factor in the development and progression of alzheimer’s disease. triazine derivatives possess a wide range of pharmacological activities including anti-oxidative and anti-in.ammatory actions. in this study, we aimed to investigate the possible protective effect of 3-thioethyl-5,6-dimethoxyphenyl-1,2,4-triazine (tedmt) on h2o2-...
