A novel series of substituted 3-[3-(aminopropyl)-4, 5, 6, 7-tetrahydro-1H-indol-2-ylmethylene]- 1, 3-dihydro-indole-2-ones was discovered as potent inhibitors of the non-receptor tyrosine kinase Src and Yes. A structure–activity relationship was developed in order to optimize their potency and selectivity. Syntheses of these compounds are also described herein.
