Libraries of spiro[cyclopropane-1,3'-indolin]-2'-ones were synthesized and evaluated for their biological activity against five different human cancer cell lines HT-29 (colon cancer), DU-145 (prostate cancer), Hela (cervical cancer), A-549 (Lung cancer), and MCF-7 (breast cancer). Many compounds of the series exhibited promising anticancer activity (IC50 < 20 mu M) against the studied cell lines. Based on the screening results, a structure activity relationship (SAR) of the pharmacophore was proposed. Among the series compound 6b and 6u showed significant activity against human prostate cancer cell line, DU-145. Flow cytometric analysis showed that these two compounds arrested the cell cycle in the G0/G1 phase leading to caspase-3 dependent apoptotic cell death. Further, measurement of mitochondrial membrane potential and Annexin V-FITC assay also suggested that 6b and 6u induced cell death by apoptosis. (C) 2015 Elsevier Ltd. All rights reserved.

The present study involves the design of a series of 3-aryl-9-acetyl-pyridazino[3,4-b]indoles as constrained chalcone analogues. A retrosynthetic route was proposed for the synthesis of target compounds. All the synthesized compounds were evaluated for in-vitro cytotoxicity against THP-1, COLO-205, HCT-116 and A-549 human cancer cell lines. The results indicated that 2a, 3a, 5a and 6a possessed significant

substituted isatins were subjected to Aldol condensation with various ketones. The resulted 3-hydroxy compounds were transformed into fluorine derivatives. Thus obtained, 3-fluoro-3-substituted oxindoles were screened for Insilco evaluation against anti-cancer targets VEGFR2 and GSK-3β. The study reveals that the fluoro compounds showed binding at their active sites. Particularly, compounds 4i, 4n and
