Popis: | Gene fusions and point mutations of RET kinase are crucial for driving thoracic cancers, including thyroid cancer and non-small cell lung cancer. Various scaffolds based on different heterocycles have been synthesized and evaluated as RET inhibitors. In this work, we investigate pyrrolo[2,3-d]pyrimidine derivatives for inhibition of RET-wt, drug resistant mutant RET V804M and RET gene fusion driven cell lines. Several compounds were synthesized and the structure activity relationship was extensively studied to optimize the scaffold. Thieno[2,3-d]pyrimidine, a bioisostere of pyrrolo[2,3-d]pyrimidine, was also explored for the effect on RET inhibition. We identified a lead compound, 59, which shows low nanomolar potency against RET-wt and RET V804M. Further 59 shows growth inhibition of LC-2/ad cells which RET-CCDC6 driven. We also determined that 59 is a type 2 inhibitor of RET and demonstrated its ability to inhibit migration of tumor cells. Based on computational studies, we proposed a binding pose of 59 in RET pocket and have quantified the contributions of individual residues for its binding. Together, 59 is an important lead compound which needs further evaluation in biological studies. |
