Cimicifugic acid D (2-Caffeoylpiscidic acid) is a benzyl tartaric acid ester that can induce vasorelaxation and an endothelium-dependent relaxation mechanism in pre-constricted rat aortic strips. During norepinephrine-induced contractions in rat aortic strips, Cimicifugic acid D inhibits extracellular Ca2+ influx through receptor-operated Ca2+ channels (ROC), while it does not affect voltage-dependent Ca2+ channels (VDC) or K+-induced contractions.

| Description | Cimicifugic acid D (2-Caffeoylpiscidic acid) is a benzyl tartaric acid ester that can induce vasorelaxation and an endothelium-dependent relaxation mechanism in pre-constricted rat aortic strips.

| In vitro | Cimicifugic acid D, at a concentration of 300 μM for 1 hour in rat aortic strips, can relax aortic strips pre-contracted with Norepinephrine and reduce its concentration-dependent contraction. Additionally, Cimicifugic acid D at 30 μM for 1 hour can inhibit Ca 2+ -induced contraction in aortic strips pre-treated with Norepinephrine. |
