SUBSTANCE P 化学特性,用途語,生産方法
作用機序
Substance P is an 11-amino-acid neuropeptide belonging to the tachykinin family, mediating its biological
actions through activation of G protein–coupled tachykinin (neurokinin-1 [NK1]) receptors. Its proposed
physiological roles include inflammation, pain, GI and respiratory function, stress responses, and emesis.
Substance P is uniquely associated with the monoamine neurotransmitters, 5-HT and NE.
臨床応用
The 5-HT neurons
coexpress substance P, and the firing of NE neurons is modulated by substance P. Preclinical studies have
supported a role of the substance P–NK1 receptor system in stress-related disorders, which has guided the
antidepressant development of centrally active NK1 receptor antagonists, such as aprepitant. The NK1
antagonists are generally well tolerated and exhibit less nausea and sexual dysfunction than some currently
used antidepressants.
