2,4-Disubstituted pyrimidines: A novel class of KDR kinase inhibitors
摘要:
2,4-Disubstituted pyrimidines were synthesized as a novel class of KDR kinase inhibitors. Evaluation of the SAR of the screening lead compound 1 (KDR IC50 = 105 nM, Cell IC50 = 8% inhibition at 500 nM) led to the potent 3,5-dimethylaniline derivative 2d (KDR IC50 = 6 nM, cell IC50 = 19 nM).

A simple, sustainable, efficient, mild, and low‐cost protocol was developed for d‐glucose‐assisted Cu‐catalyzed Ullmann reactions in water for amides, carbamates, and nitrogen‐containing heterocycles. The reaction was compatible with diverse aryl/heteroaryl iodides, giving highly substituted pyridine, indole, or indazole rings. This method offers an attractive alternative to existing protocols, because
