Synthesis, Crystallographic Studies and Biological Evaluation of Some 2-Substituted 3-Indazolyl-4(3H)-quinazolinones and 3-Indazolyl-4(3H)-benzotriazinones
摘要:
A number of new 3-(indazol-3 and 5-yl)-4(3H)-quinazolinone and 4(3H)-benzotriazinone derivatives were prepared by reaction of 3- or 5-(2-aminobenzamido)indazole with ethyl orthoesters and nitrous acid respectively. Structures were established on the basis of analytical and spectroscopic data. Single-crystal X-ray analysis confirmed the quinazolinone structure of compounds (5). The 4(3H)-quinazolinones and 4(3H)-benzotriazinones were tested at 200 mu g/ml for antimicrobial activity against C. albicans, C. tropicalis and S. aureus, at 100 mu M for their antitumor effect on human-lymphoblast-like cells and finally at 500 mu M for 3 alpha-hydroxysteroid dehydrogenase (3 alpha-HSD) inhibition.
