A novel series of C-3 urea, amide, and carbamate fused dihydroindazolocarbazole (DHI) analogs are reported as highly potent dual inhibitors of TIE-2 and VEGF-R2 receptor tyrosine kinases with excellent cellular potency. Structure–activity relationship (SAR) studies indicate the optimal N-13 alkyl substitutions are n-propyl and i-butyl. The isopropyl carbamate 39 displayed good dual enzyme, cell potency, and rat pharmacokinetic properties for advancement to in vivo evaluation.
