Discovery of highly potent Src SH2 binders: Structure–activity studies and X-ray structures
摘要:
Optimization of the hydrophobic moiety of caprolactam/thiazepinone based compounds led to the identification of potent Src SH2 binders in two different series incorporating a phosphotyrosine group (RU 81843) or a phosphobenzoic group (RU 79181). The X-ray co-structures with the Src SH2 domain revealed different binding modes for RU 81843 and RU 79181, and an excellent fit between RU81843 and the Src SH2 protein thus explaining its high potency (9 nM, 15-fold more potent than pYEE1 reference peptide).

A C78fullerene related structure (of C78:1 and C78:4, the last undiscovered C78 IPR isomer) has been synthesized and investigated as a pyrolytic precursor. The pyrolysis of precursor containing all 78 carbon atoms in the required positions and 93 of the 117 C−C bonds, needed for fullereneformation, showed selectivity for C78fullereneformation. In independent experiments it has been shown that the
