New triazolothiadiazine derivatives were synthesized via the ring closure reaction of 4-
amino-5-substituted-2, 4-dihydro-3H-1, 2, 4-triazol-3-thiones with phenacyl bromides. The …

New triazolothiadiazine derivatives 5a–h were synthesized from 4‐amino‐3‐(4‐pyridyl)‐5‐
mercapto‐4H‐1, 2, 4‐triazole (3) with substituted aryl hydrazonoyl chlorides 4a–h. The …

The aim of this study was to describe the synthesis of four new 2-(3, 4-diphenyl-3 H-thiazol-2-
ylidene) amino-4, 6-dimethylpyrimidine derivatives, which were screened for their …

Background: One of the important chemical agents in designing of anti-convulsant,
antiatherosclerotic and anti-cancer drugs are pyridine derivatives. Alkyl and aryl derivatives …

A series of new 7 H-7-alkoxy-3-alkyl/phenyl-6-aryl-s-triazolo [3, 4-b][1, 3, 4] thiadiazines (3,
4) were synthesized by the reaction of various α, α-dibromoacetophenones 1 with 3 …

A series of s-triazolobenzothiazolylthioacetyl/propionyl amino acid derivatives were
synthesized with the aim of evaluating their antifungal activity. Their chemical structures …

A series of novel ([1, 2, 4] triazolo [1, 5-c] quinazolin-2-ylthio) carboxylic acids 2a—d and
esters 3a—l were synthesized and evaluated for antimicrobial activity. Alkylation of …

New pyrazoline derivatives bearing an oxadiazole moiety were synthesized via the reaction
of 1-(chloroacetyl)-3-(2-furyl/thienyl)-5-aryl-2-pyrazolines with 5-substituted-1, 3, 4 …

A new series of novel bis [1, 2, 4] triazolo [3, 4-b][1, 3, 4] thiadiazines 7a–j has been
synthesized by the reaction of [5, 5'-methylenebis (3-methylbenzofuran-7, 5-diyl)] bis [(4 …

The increasing clinical importance of drug-resistant fungal and bacterial pathogens has lent
additional urgency to microbiological research and new antimicrobial compound …
