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.

没有序列识别的功能,他就是简单的催化相邻DNA链的5-P末端和3'-OH末端以磷酸二酯键结合的反应,需ATP作辅酶。 不仅可以催化粘性末端之间或平滑末端之间的DNA的连接,也催化DNA与RNA之间以及少数RNA之间的连接。
