iNOS Inhibitors (60):

Cat. No. Product Name Effect Purity
  • HY-P1956
    Human serum albumin
    		Inhibitor 99.9%
    Human serum albumin (HSA) is the most abundant protein in plasma and is a major determinant of plasma oncotic pressure. Human serum albumin exhibits antioxidant, anticoagulant, anti-inflammatory, anti-platelet aggregation activities as well as colloid osmotic action. Human serum albumin can block the inhibitory effect of GML on human T cells, providing protective function for T cells. Human serum albumin is also associated with cardiovascular diseases and can partially prevent the LPS (HY-D1056) induced oxidative stress, as well as the upregulation of NF-κB, NF-κB, and peroxynitrite (ONOO−) in the vascular wall, contributing to the reduction of blood pressure.
