Abstract

A series of 1,4-dihydroindeno[1,2-c]pyrazoles was prepared and evaluated for their enzymatic inhibition of KDR kinase. Computer modeling studies revealed the importance of attaching a basic side chain in predicting the binding mode of those compounds. Further investigation of structure-activity relationships led to 19, a lead compound with an acceptable selectivity profile, activity in whole cells, and good oral efficacy in an estradiol-induced murine uterine edema model of VEGF activity. © 2006 Elsevier Ltd.
