this end a study was carried out to fully characterize and optimize the irreversible covalent UCHL1 inhibitor VAEFMK. Structure-activity relationship studies identified modifications to improve activity versus the target and a full cellular characterization was carried out for the first time with this scaffold. The studies produced a new inhibitor, 34, with an IC50 value of 7.7 µM against UCHL1 and no
dipeptides in 76–99% yields with 70–>99% de and dipeptides-containing medicine analogues in 74–99% yields with 79–97% de in aqueous THF at −15 °C via the mixed carbonic carboxylicanhydrides by the activation of the corresponding carboxylic acids. We observed that the anilide l-Phe-l-Phe-NHC6H4-4-OH, one of the deprotecting medicine analogues, was cleaved at the C-terminal of l-phenylalanine (l-Phe) by
我们已经成功地以 76–99% 的收率和 70–>99% 的去氧化酶绿色和经济地合成了各种二肽和含二肽的药物类似物,在 -15 °C 的水性 THF 中以 79–97% 的去氧化酶的收率在 -15 °C 下通过通过相应羧酸的活化得到混合碳酸酐。我们观察到苯胺l -Phe- l -Phe-NHC 6 H 4 -4-OH 是一种脱保护药物类似物,在饥饿条件下被贝克酵母在l-苯丙氨酸 ( l -Phe) 的C端裂解条件,然后处理新鲜制备的 PhCH 2 CH 2 CO 2 CO 2Et 从 3-苯基丙酸、ClCO 2 Et 和 Et 3 N 在 MeCN 中得到 PhCH 2 CH 2 CONHC 6 H 4 -4-OH 和 PhCH 2 CH 2 CO - 1 -Phe-NHC 6 H 4 -4-OH收益率分别为 46% 和 42%。有趣的是,贝克酵母对l -Phe- d -Phe-NHC 6
