摘要

This letter describes a series of small molecule inhibitors of IGF-1R with unique time- dependent binding kinetics and slow off-rates. Structure–activity and structure–kinetic relationships were elucidated and guided further optimizations within the series, culminating in compound 2. With an IGF-1R dissociative half-life (t 1/2) of> 100 h, compound 2 demonstrated significant and extended PD effects in conjunction with tumor growth ...
