The invention discloses application of 4-chloro-3-
ethyl phenol in preparation of a
medicine for preventing or treating
ulcerative colitis and septicopyemia, and relates to the technical field of biological
medicine. Experiments prove that the raney
receptor (RyRs)
agonist 4-chloro-3-
ethyl phenol has a remarkable effect on preventing or treating
ulcerative colitis and septicopyemia, and the 4-chloro-3-
ethyl phenol is a clinical potential
medicine for preventing or treating
ulcerative colitis and septicopyemia; meanwhile, 4-chloro-3-ethylphenol is used as a reliable tool, two components of a
calcium channel (SOCE) controlled by a
calcium pool can be clearly distinguished, that is, ER / Ca < 2 + > release is induced through RyR, but Ca < 2 + > passing through SOC in vascular endothelial cells is blocked from entering, and dual effects are achieved; further experiments prove that pure endothelial
cell RyR / ER / Ca < 2 + > release is a unique way for regulating EDH-mediated
artery vasodilation in a healthy state, and has an anti-inflammatory effect on ulcerative
colitis and septicopyemia.
