The DPPIV Drug Discovery Kit is a complete assay system designed to screen DPPIV inhibitors, providing enough material to perform at least 96 assays. DPPIV (DPP4, CD26) is a member of the class of proteases known as prolyl peptidases, which cleave proteins after proline residues and is thought to play roles in diabetes, cancer, and autoimmune diseases, making it a target for drug discovery.

The kit contains both a chromogenic substrate (H-Gly-Pro-pNA; K_m=114 µM) and a fluorogenic substrate (H-Gly-Pro-AMC; K_m=50 µM).

Cleavage of the p-nitroaniline (pNA) from the colorimetric substrate increases absorbance at 405 nm. The fluorimetric assay is based on the cleavage of 7-amino-4-methylcoumarin (AMC) moiety from the C-terminus of the peptide substrate, which increases its fluorescence intensity at 460 nm. The kit is useful to screen inhibitors of DPPIV, a potential therapeutic target. A DPPIV inhibitor, P32/98 (K_I=130 nM12), is included for use as a control. Other DPP enzymes are available for specificity profiling.

二肽基肽酶(dipeptidyl peptidase ，DPP)

二肽基肽酶(dipeptidyl peptidase ，DPP)是蛋白酶家族中的脯基肽酶成员，其可剪切含脯氨酸的蛋白，其中DPPIV (DPP4, CD26),是一种丝氨酸二肽基肽酶，其剪切靶多肽（细胞趋化因子如CXCL11和肽类激素如GLP-1）N端的X-Ala or X-Pro基. CD26是一种高度保守、分布于多种细胞的，具有跨膜域和很短的胞质域，但常被剪切和释放作为可溶性环化4型，常形成自身二聚体或与FAP形成异二聚体。DPPⅣ的天然底物多种多样，在体内执行多种重要功能。它还是细胞膜受体和共刺激分子，从而参与机体的免疫调节、细胞移行、细胞黏附和细胞调亡过程，故与多种疾病的发病有关。各种DPP-IV抑制剂对II型糖尿病、自身免疫性疾病及细胞增殖性疾病（肿瘤）的治疗具有重要意义。DPP-4是重要的药物开发靶点，其中DPP-IV抑制剂Januvia磷酸西他列汀Sitagliptin  phosphate已作为抗糖尿病药物上市。
