Design, synthesis and anticancer evaluation of novel thiazine, pyrimidine and pyridine derivatives
Acylisothiocyanate (1) was allowed to react with benzylidene malononitrile producing oxazine derivative (2). Also, compound (1) was reacted with sodium azide followed by refluxing with sodium ethoxide affording thiazinotetrazole derivative (4). The reaction of acetylacetone with compound (1) gave pyridine derivative (5) by intramolecular cycloaddition while it was reacted with N-methyl aniline ...
متن کاملSynthesis and antioxidant and antitumor activity of novel pyridine, chromene, thiophene and thiazole derivatives.
2-Tosylacetonitrile (1) when reacted with α,β-unsaturated nitriles 2a-c or a mixture of formaldehyde and 3-amino-2-substituted-pent-2-endinitriles 6a,b yielded pyridine derivatives 3a-c and 9a,b, respectively, while when subjected to react with salicylaldehyde yielded chromene derivatives 4 and 5, subsequently. The behavior of thiocarbamoyl derivative 10 derived from 1 towards some α-halogenate...
متن کاملSynthesis, Characterization and Antitumor Activity of Some Novel Pyrimidine Sulfonamide Derivatives
The key intermediate in this study is synthesis of pyrimidine-5-sulfonamides 2a,b. Further modification of starting material by treatment with ethanolamine, anthranilic acid and 3-bromopropanoic acid yielded the condensed pyrimidine derivatives incorporating sulfonamide moiety such as: imidazopyrimidine 3a,b, pyrimidoquinazoline 4a,b and pyrimidothiazine derivatives 5a,b, respectively, in good ...
متن کاملSYNTHESIS AND ANTIBACTERIAL ACTIVITY OF NEW SULFONAMIDE ISOXAZOLO[5,4-b]PYRIDINE DERIVATIVES.
A series of novel sulfonamide isoxazolo[5,4-b]pyridines were synthesized. The substrates for their synthesis were 3-aminoisoxazolo[5,4-b]pyridine and selected aryl sulfonic chlorides, chlorosulfonic acid and selected amines. Reactions were carried out using the classical and microwave methods. Selected compounds were tested towards antibacterial and antiproliferative activity. The structure of ...
متن کاملSynthesis of Some New 1,3,4-Thiadiazole, Thiazole and Pyridine Derivatives Containing 1,2,3-Triazole Moiety.
In this study, 1-(5-Methyl-1-(p-tolyl)-1H-1,2,3-triazol-4-yl)ethan-1-one, was reacted with Thiosemicarbazide, alkyl carbodithioate and benzaldehyde to give thiosemicarbazone, alkylidenehydrazinecarbodithioate and 3-phenylprop-2-en-1-one-1,2,3-triazole derivatives. The 1,3,4-thiadiazole derivatives containing the 1,2,3-triazole moiety were obtained via reaction of alkylidenecarbodithioate with h...
