Synthesis and antiproliferative evaluation of some new amidino-substituted bis-benzothiazolyl-pyridines and pyrazine.
Novel diamidino substituted conformationally restricted derivatives of bis-benzothiazolyl-pyridines and pyrazine were synthesized and their antiproliferative activity against several human cancer cell lines were determinated. The synthetic approach used for preparation of isomeric amidinobenzotiazolyl disubstituted pyridines 3a-3k and pyrazine 3l was achieved by condenzation reaction of commerc...

Pathogenic infections and inflammation are very common ailments humans suffer. Upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. In line with these developments the synthesis of N-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4H-1...

Synthesis and anticonvulsant activity of some new 2-substituted 3-aryl-4(3H)-quinazolinones.
A series of 4(3H)-quinazolinones structurally related to 2-methyl-3-o-tolyl-4(3H)-quinazolinone (methaqualone, 3) were synthesized and evaluated for anticonvulsant activity. Preliminary screening of these compounds revealed that 2-[2-oxo-2-(4-pyridyl)ethyl]-3-aryl-4(3H)-quinazolinones 6l and 8i, 8k, and 8p-r having a single ortho substituent on the 3-aryl group had the most promising anticonvul...
متن کاملSynthesis and antimicrobial activity of new polyfunctionally substituted pyridines and their fused derivatives
Ethyl pyruvate (EP) on reacting with malononitrile or isothiocyanates gives the pyridine derivati ves 5 and 9a , b , respecti vely. Chalcone deri vati ve of EP reacts with malononitrile to yield the pyran derivative which in turn IS transformed into pyridine derivative 14. Reactivity of 5 and 9a towards di fferent organic reagents has been investigated . Antimicrobial activity of some newly syn...
