pharmaceutical lead target. On-resin methods for peptide synthesis offer potential synthetic advantages; however, strategies for on-resin formation of multiple disulfides have historically been low-yielding. Here, we harness the reactivity of the Allocam protecting group and employ 3-amino acid spacer strategy to synthesize α4/7-conotoxin LvIA via three different on-resin strategies, each of which results
α4/7-Conotoxin LvIA 是 α3β2 烟碱乙酰胆碱受体的异构体选择性抑制剂。这种毒素的有效合成策略对于提高其作为受体功能探针和潜在药物先导靶标的实用性至关重要。树脂上肽合成方法具有潜在的合成优势;然而,在树脂上形成多种二硫化物的策略历来收率较低。在这里,我们利用 Allocam 保护基团的反应性,并采用 3-氨基酸间隔策略通过三种不同的树脂策略合成 α4/7-芋螺毒素 LvIA,每种策略的分离产量均高于之前的完全树脂策略接近。
