Synthesis of acyloxymethyl ester prodrugs of the transferable protein farnesyl transferase substrate farnesyl methylenediphosphonate
摘要:
Three isoprenoid diphosphate analogues of farnesyl diphosphate (FPP) where the diphosphate has been replaced by methylene diphosphonate and the negative charges masked by frangible pivaloyloxymethyl (POM) esters were prepared. Farnesyl methylenediphosphonate is a sub-micromolar substrate for protein farnesyl transferase. The tripivaloyloxymethyl esters of isoprenoid methylenediphosphonate have significantly increased lipophilicity and may act as important farnesyl diphosphate prodrugs. (C) 2004 Elsevier Ltd.

Evaluation of protein farnesyltransferase substrate specificity using synthetic peptide libraries
摘要:
Farnesylation, catalyzed by protein farnesyltransferase (FTase), is an important post-translational modification guiding cellular localization. Recently predictive models for identifying FTase substrates have been reported. Here we evaluate these models through screening of dansylated-GCaaS peptides, which also provides new insights into the protein substrate selectivity of FTase. (c) 2007 Elsevier Ltd.

followed by ester hydrolysis, chlorination, and pyrophosphorylation. Additional substitution of three methylenes for the beta-isoprene of FPP gave photoprobe 6 in nine steps. Preparation of the analogues required TiCl(4)-mediated imine formation prior to NaBH(OAc)(3) reduction for anilines with a pK(a) < 1. The azide moiety was not affected by Ph(3)PCl(2) conversion of allylic alcohols 13-16 into corresponding

near their C-termini. Here we describe the preparation of isoprenoid diphosphate analogues incorporating diazirine groups that can be used to probe interactions between prenylated proteins and other proteins that interact with them. Studies using synthetic peptides and whole proteins demonstrate that these diazirine analogues are efficient substrates for prenyltransferases. Photo-cross-linking experiments
异戊二烯化蛋白质含有与其 C 末端附近的半胱氨酸残基相连的 C 15或 C 20 类异戊二烯。在这里,我们描述了掺入二氮丙啶基团的类异戊二烯二磷酸类似物的制备,该类似物可用于探测异戊二烯化蛋白质和与其相互作用的其他蛋白质之间的相互作用。使用合成肽和完整蛋白质的研究表明,这些二氮丙啶类似物是异戊二烯基转移酶的有效底物。使用掺有二氮丙啶功能化类异戊二烯的肽进行光交联实验,选择性地与几种不同的蛋白质交联。这些新的类异戊二烯类似物应该广泛用于蛋白质异戊二烯化的研究。
