摘要:
Optimization of a series of R132H IDH1 inhibitors from a high throughput screen led to the first potent molecules that show robust tumor 2-HG inhibition in a xenograft model. Compound 35 shows good potency in the U87 R132H cell based assay and similar to 90% tumor 2-HG inhibition in the corresponding mouse xenograft model following BID dosing. The magnitude and duration of tumor 2-HG inhibition correlates with free plasma concentration.
