The absolute configuration of reveromycin A, a new inhibitor of the signal transduction of epidermal growth factor (EGF), is determined on the basis of chemical degradation and spectroscopic evidence.
基于化学降解和光谱证据,确定了表皮生长因子(EGF)信号转导的新型抑制剂瑞维莫司A的绝对构象。
Synthesis and biological activities of reveromycin A and spirofungin A derivatives
Various derivatives of reveromycin A, an inhibitor of eukaryotic cell growth, and spirofungin A, focusing on the 5S hydroxyl group and C18 hemisuccinyl group, were synthesized and their inhibitory effects on both the isoleucyl-tRNAsynthetase activity and the survival of osteoclasts, and activities on the morphological reversion of src(ts)-NRK cells were examined. It was found that 2,3-dihydroreveromycin
eukaryotic cell growth, were prepared and their inhibitory effects on both isoleucyl-tRNA synthetase activity and in vitro protein synthesis, and activities on the morphological reversion of src(ts)-NRK cells were assayed. The C5 hydroxyl group and C24 carboxyl group are particularly important for these activities.
