DPPIV drug discovery kit    Enzo lifescience BML-AK499;二肽基肽酶 4 /二肽基肽酶IV  檢測試劑盒,*,現(xiàn)貨供應(yīng)!

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; Km=114 µM) and a fluorogenic substrate (H-Gly-Pro-AMC; Km=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 (KI=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員,其可剪切含脯氨酸的蛋白,其中DPPIV (DPP4, CD26),是一種絲氨酸二肽基肽酶,其剪切靶多肽(細(xì)胞趨化因子如CXCL11和肽類激素如GLP-1N端的X-Ala or X-ProCD26是一種高度保守、分布于多種細(xì)胞的,具有跨膜域和很短的胞質(zhì)域,但常被剪切和釋放作為可溶性環(huán)化4型,常形成自身二聚體或與FAP形成異二聚體。DPP的天然底物多種多樣,在體內(nèi)執(zhí)行多種重要功能。它還是細(xì)胞膜受體和共刺激分子,從而參與機(jī)體的免疫調(diào)節(jié)、細(xì)胞移行、細(xì)胞黏附和細(xì)胞調(diào)亡過程,故與多種疾病的發(fā)病有關(guān)。各種DPP-IV抑制劑對II型糖尿病、自身免疫性疾病及細(xì)胞增殖性疾?。[瘤)的治療具有重要意義。DPP-4是重要的藥物開發(fā)靶點(diǎn),其中DPP-IV抑制劑Januvia磷酸西他列汀Sitagliptin  phosphate已作為抗糖尿病藥物上市。
