The heterocyclic fused rings quinazoline and quinazolinone have drawn a huge
consideration owing to their expanded applications in the field of pharmaceutical chemistry …

Nitrogen heterocyclic rings have participated to constitute most of the drugs and several
pharmacologically related compounds. The existence of such hetero atoms/groups in …

Abstract A new series of 1, 2, 4‐triazolo [4, 3‐c] quinazoline derivatives was designed and
synthesized as Topo II inhibitors and DNA intercalators. The cytotoxic effect of the new …

A series of novel 8/10-trifluoromethyl-substituted-imidazo [1, 2-c] quinazolines have been
synthesized and evaluated in vivo (rat paw edema) for their anti-inflammatory activity and in …

Abstract New series of triazolo [4, 3-c] quinazolines were designed, synthesized and their
structures were elucidated using different spectroscopic techniques. They were evaluated …

The combinatorial library of novel potential anticancer agents, namely, 2-(alkyl-, alkaryl-, aryl-
, hetaryl-)[1, 2, 4] triazolo [1, 5-c] quinazolines, was synthesized by the heterocyclization of …

A novel series of 7‐benzylidene‐3, 3a, 4, 5, 6, 7‐hexahydro‐3‐phenyl‐2H‐indazole
substituted at the 2‐position were synthesized. The reaction of 2, 6‐bis …

Background:(Quinazoline-4-ylidene) hydrazides are valued intermediates in modern
organic chemistry, as they are commonly used for the synthesis of substituted [1, 2, 4] …

Synthesis of some new derivatives of 2‐aryl‐4‐oxo‐1‐(4‐quinazolyl) quinazolines is
described. Methyl N‐(4‐quinazolyl) anthranilate was allowed to react with phenyl iso (thio) …

A new series of quinazolin‐4 (3H)‐one derivatives containing either a thiazole or a 1, 3, 4‐
