Human blood group B galactosyltransferase (GTB) catalyzes the galactosylation of the H antigen and is responsible for the formation of the blood group antigen of phenotype B. The ABO blood group system is well studied and routinely serotyped before transfusion and transplantation. Blood type subgroups have been repeatedly linked to an increased occurrence of diseases (e.g., a highly increased incidence
人血型B半乳糖基转移酶(GTB)催化H抗原的半乳糖基化,并负责表型B血型抗原的形成。对ABO血型系统进行了深入研究,并在输血和移植前常规进行了血清分型。血型亚组已与疾病增加(例如,血型B型个体胰腺癌的发病率大大增加)反复联系在一起。3-苯基-5-(哌嗪-1-基)-1,2,4-噻二唑1先前已经描述抑制GTB与ķ我的800μ值米。在这项工作中,我们描述了一种计算机指导的片段生长方法,用于优化该片段,随后通过合成最有希望的配体来实现该方法。放大片段的苯基部分1至萘基时导致配体3-(萘-1-基)-5-(哌嗪-1-基)-1,2,4-噻二唑2,其示出了三倍的改善结合亲和力(ķ我= 271μ米)。
