Application of Off-Rate Screening in the Identification of Novel Pan-Isoform Inhibitors of Pyruvate Dehydrogenase Kinase
摘要:
Libraries of nonpurified resorcinol amide derivatives were screened by surface plasmon resonance (SPR) to determine the binding dissociation constant (off-rate, k(d)) for compounds binding to the pyruvate dehydrogenase kinase (PDHK) enzyme. Parallel off-rate measurements against HSP90 and application of structure-based drug design enabled rapid hit to lead progression in a program to identify pan-isoform ATP-competitive inhibitors of PDHK. Lead optimization identified selective sub-100-nM inhibitors of the enzyme which significantly reduced phosphorylation of the E1 alpha subunit in the PC3 cancer cell line in vitro.

Copper triflate catalyzedoxidative C–H functionalization of glycine derivatives with allyltributyltin has been established using oxygen or tert-butyl hydroperoxide as oxidant. Various glycine esters and glycine amides were suitable substrates for this oxidative allylation reaction and afforded the desired homoallylic amines in moderate to good yields.

light-mediated protocol for site-specific C(sp3)–H hydrazination of glycinederivatives and peptides with azo compounds has been developed. This C(sp3)–N coupling reaction proceeded smoothly under photo-irradiation conditions in the absence of any catalysts and additives, thus providing a convenient and facile method for efficient preparation of unnatural α-amino acids and precise modification of short peptides
