Two new microbial metabolites, tryptopeptins A (1) and B (2), were isolated from the cultured broth of Streptomyces sp. KUSC-G11, as modulators of the transforming growth factor-β (TGF-β) signaling pathway. Their chemical structures consisting of isovalerate, N-Me-l-Val, l-allo-Thr, and a tryptophan-related residue were elucidated on the basis of spectroscopic analyses, while they were unambiguously
从链霉菌的培养液中分离出两种新的微生物代谢物-胰链素A(1)和B(2)。KUSC-G11,作为转化生长因子-β(TGF-β)信号传导途径的调节剂。其由异戊酸的化学结构,Ñ -Me-升-Val,升-同种异体-Thr,和色氨酸相关的残余物中阐明分光分析的基础上,而他们明确地通过全合成来确定。使用天然和合成的胰蛋白ept素进行的结构-活性关系(SAR)研究表明,位于C区的α,β-环氧酮功能很重要总站。这些新的TGF-β信号传导调节剂对于开发针对TGF-β相关疾病(例如纤维化和癌症)的新药线非常有用。
