产品介绍
CTS-1027 是一种有效的 MMP 小分子抑制剂,对 MMP2、MMP13 的 IC50 分别为 0.3 nM、0.5 nM,选择性比 MMP1 高 >1,000 倍。

Animal experiment:

For experimental procedures, mice are anesthetized with ketamine 60 mg/kg plus xylazine 10 mg/kg body weight by intraperitoneal injection. After a midline upper-abdominal incision, the peritoneal cavity is opened, the abdominal wall retracted, and the common hepatic bile duct is double-ligated below the bifurcation and transected between the ligatures as previously described by us in detail. Sham-operated mice, used as controls, also underwent similar laparotomy with exposure but without ligation of the common bile duct. The fascia and skin of the midline abdominal incision are closed with sterile surgical 5-0 sutures. Either CTS-1027 or the vector carboxymethylcellulose are administered by gavage in a dose of 10 mg/kg body weight once a day. Drugs are prepared freshly on the day of the study. After 14 days of BDL and gavage, mice are re-anesthetized, sacrificed and blood is obtained from the inferior vena cava for serum total bilirubin and ALT determinations and the liver is removed, cut into small pieces and either snap-frozen in liquid nitrogen for storage at –80℃ or fixed in freshly prepared 4% paraformaldehyde in phosphate-buffered saline (PBS) for 48 hours at 4℃ for additional studies. Liver tissue is also subjected to RNA extraction using the Trizol reagent. Serum bilirubin and ALT determinations are performed as previously described.

产品描述

CTS-1027 is a selective inhibitor of MMP with IC50 value of 0.4 nM for MMP 2 and 0.6 nM for MMP13 [1].
MMPs (matrix metalloproteinase) are zinc-dependent endopeptidases and play an important role in degrading all kinds of extracellular matrix proteins. It is well known that MMPs involve in the cleavage of cell surface receptors, the release of apoptotic ligands, and inactivation chemokine/cytokine. And MMPs also play a pivotal role in cell proliferation, migration, differentiation, angiogenesis, apoptosis and host defense [2] [3].
In C57/BL6 mice model suffered bile duct ligation (BDL) for 14 days, gavage CTS-1027 reduced apoptosis of hepatocyte and bile infarcts which was a histologic indicator of liver injury at the same time activated stellate cells and reduced hepatic fibrogenesis [4].
