3,5-Disubstituted-indole-7-carboxamides as IKKβ Inhibitors: Optimization of Oral Activity via the C3 Substituent.

abstract：:In light of the biomedical significance of metallo-β-lactamases (MβLs), ten new mercaptoacetic acid thioester amino acid derivatives were synthesized and characterized. Biological activity assays indicated that all these synthesized compounds are very potent inhibitors of L1, exhibiting an IC50 value range of 0.018-2....
