About indazole synthesis review
Substitution at R3 with a halogen or alkoxy group (74f–74i) triggered a slight increase in cellular potency Using the halide analogs (74g–h) showing highest the potency in the group. Further more optimization triggered the discovery of 74i–j, with 74k as essentially the most active compound during the sequence (pIC50 = 6.seventy seven) with e
