Novel benzimidazoles, benzothiazoles and benzofurans incorporating pyrazole moiety have been synthesized and screened for their antiangogenic activities, by testing their ability to inhibit human umbilical vein endothelial cell (HUVEC) proliferation, cord formation and migration in response to chemoattractant. 3 compounds 19, 23 and 26 showed antiangiogenic activities at non-cytotoxic concentrations. Compound 19 was the most active with chemotaxis activity data nearly comparable to that of the positive control, TNP-470. Compound 42 showed a significant cytotoxic effect on the tested cancer cell lines and less antiangiogenesis activity compared to compounds 19, 23 and 26. All the tested compounds, in contrary to TNP-470, interfered with the migratory function of HUVECs in response to vascular endothelial growth factor rather than the endothelial cells proliferation or cord formation. Moreover, a docked pose of compounds 19 and 26 was obtained bound to kinase insert domain receptor using Molecular Operating Environment module. Georg Thieme Verlag KG · Stuttgart · New York.

A series of novel pyrazolyl 2-aminopyrimidine derivatives (7a-t) were designed based on scaffold hopping techniques, synthesized and biologically evaluated for their HSP90 inhibition and anticancer activity. Several compounds exhibited potent HSP90 inhibition with IC50 values less than that of the reference standard 17-AAG (1.25 μM). The most potent compound 7t displayed excellent HSP90 inhibition with an IC50 of 20 nM and in vitro antiproliferative potential against three cancer cell lines (IC50 5 μM). 7t also induced dose dependent degradation of client proteins (pHER2 and pERK1/2) in Western blot analysis. Several structural features of 7p-t oriented the molecules to retain all the essential binding interactions with HSP90, as observed by rationalized docking studies. Therefore, the para-nitrophenyl ring on the central pyrazole ring along with the 2-amino group on the pyrimidine ring are the crucial features in the development of novel HSP90 inhibitors based on this scaffold for targeted anticancer therapy.
