PK 44 phosphateDescription:IC50: 15.8 nm (DPP-IV)The protein encoded by the DPP4 gene is an antigenic enzyme expressed on the surface of most cell types and is associated with immune regulation, signal transduction and apoptosis. Inhibitors of dipeptidyl peptidase 4, also DPP-4 inhibitors or gliptins, are a class of oral hypoglycemics that block DPP-4. They can be used to treat diabetes mellitus type 2 (http://en.wikipedia.org/wiki/Dipeptidyl_peptidase-4_inhibitors). PK 44 phosphate is a potent inhibitor of dipeptidyl peptidase IV (DPP-IV).In vitro: With a potent inhibitor of dipeptidyl peptidase IV (DPP-IV), PK 44 phosphate showed more than 1000-fold selectivity for DPP-IV over DPP-8 and DPP-9 [1]. In vivo: PK 44 phosphate was found to be able to improve glucose tolerance in a mouse oral glucose tolerance assay [1]. Clinical trial: PK 44 phosphate is currently in the preclinical development and no clinical trial is ongoing.Reference:[1] Tozer et al (2010) Indole- and indazole-based inhibitors of dipeptidyl peptidase IV for the treatment of type 2 diabetes. 32nd Annual National Medicinal Chemistry Symposium Poster 52.

各位大侠:小弟最近做个长片段的CDNA与T载体的连接,片段大小6.4K,载体选用的是pUC19和pGEMT-easy,反转录酶用的是RevertAidTirstStrandcDNASynthesisKit(#K1621),CDNA第二链的扩增用的是LATaq。我是用纯病毒的RNA做模板,操作步骤严格按照说明做的,也曾经有一次获得过电泳图清晰显示的是全长6.4KB左右的片段,与载体连接,结果筛选到的几个克隆,插入的片段仅有2KB左右,奈何?可最近几次再用此反转录试剂盒却不能得到所需片段。在此,小弟想问问大家,你们是否遇到同样的问题,是如何解决的?所用的试剂(载体和酶的选择)和方法是什么,可以告诉后来者,共同进步吧。
