Design, synthesis and anticancer evaluation of novel thiazine, pyrimidine and pyridine derivatives
نویسندگان
چکیده مقاله:
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 affording thiazine derivative (7). In addition, it was reacted with cyanoacetamide producing mercaptopyrimidine derivative (9). Finally, compound (1) was refluxed with phenylhydrazine, urea, guanidinum carbonate and anthranilic acid in the presence of dry acetone affording triazole derivative (11), N-substituted pyrimidine (15), compound (18) and thiopyrimidine derivative (19) respectively. The structures of the new compounds were confirmed on the basis of elemental and spectral data. Some of the synthesized compounds were screened as anticancer.

متن کاملSynthesis, Antibacterial and Anticancer Evaluation of Some Pyrimidine Derivatives
Abstarct: A series of some new pyrimidine derivatives were synthesized via the reaction of ethyl cyanoacetate with thiourea and the appropriate aldehydes namely 2-methyl-benzaldehyde and 2-methoxy-benzaldehyde to give 1a,b. Compounds 1a,b were chlorinated to give the chloro compounds 2a,b then condensation of 2a,b via different reagents gave compounds 3-5. Compound 4b reacted with acetic anhydr...
متن کاملSynthesis and anticancer activity assay of novel chalcone sulfonamide derivatives
Chalcones, or 1,3–diaryl–2–propen–1–ones, one of the major classes of natural products and posses many useful properties like anticancer, antibacterial, antifungal, anti–inflammatory, antimalarial and anti–diabetic activity. We report in this communication the synthesis and anticancer study of a number of novel chalcone sulfonamides. Our results indicate that the synthesis of chalcone sulfonami...

متن کاملSynthesis and biological evaluation of some pyrimidine, pyrimido[2,1-b][1,3]thiazine and thiazolo[3,2-a]pyrimidine derivatives.
4,6-Diamino-1H-pyrimidine-2-thione (1) was used for the preparation of pyrimidine derivatives 2-5. Compound 5 was cyclized to produce pyrimido[2,1-b][1,3]thiazine derivative 6 which was condensed with p-chlorobenzaldehyde to give compound 7. The latter compound was reacted with hydroxylamine to give isoxazolo[4,5-d]thiazino[2,3-a]pyrimidine 8. Compound 8b was treated with 2-chloroethyl methyl e...
متن کاملSynthesis and anticancer evaluation of novel acenaphtho [1,2-e]-1,2,4- triazine derivatives
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...
