Novel indolo[2,1-b]quinazoline analogues as cytostatic agents: synthesis, biological evaluation and structure–activity relationship
摘要:
In our endeavor to design and synthesize novel anticancer agents, a new series of indoloquinazoline compounds were prepared and tested initially for anticancer activity in vitro against a panel of human cancer cell lines. Most of these compounds exhibited cytotoxic activity in in vitro screens. Compounds were selected and further evaluated using a modified Hollow Fiber Assay for their preliminary in vivo activity against 12 cell lines implanted in the subcutaneous and intraperitoneal compartments in mice. The results indicate that these compounds may constitute a new class of anticancer agents. (C) 2002 Elsevier Science Ltd. All rights reserved.

A panel of derivatives of the natural product tryptanthrin was synthesized and screened for its in vitro activity against the intracellular parasite Toxoplasma gondii. We concentrated on the modification of the 6-keto group of tryptanthrin and prepared a series of oximes, hydrazones and alcohols based on tryptanthrin. We evaluated parasite growth inhibition and host cell cytotoxicity. Our results indicate that in particular alcohol analogs are promising candidates for further investigation. (C) 2012 Elsevier Ltd.
