背景说明 |
是一种神经活性肽,刺激心脏和鳃组织的颗粒组分中的腺苷酸环化酶 (adenylate cyclase) 活性。 |
生物活性 |
Small Cardioactive Peptide B 是一种神经活性肽,能刺激心脏和鳃组织微粒馏分中腺苷酸环化酶的活性,其 EC50 值分别为 0.1 和 1.0 μM。[1] |
In Vivo |
Small cardioactive peptide B showed exert dose-dependent,reversible changes in cardiac activity when perfused through the isolated heart. The EC50 values effecting changes in heart rate and force of contraction were 3 X 10(-11)and 3 X 10(-10)M; minimum concentrations found to effect changes in heart rate and force of contraction were normally 10(-15)and 10(-12)M. When perfused through the isolated gill,small cardioactive peptide B suppressed the gill withdrawal response amplitude with a threshold concentration of 10(-14)M and an EC50 value of 3 X 10(-11)M. Suppression of the gill withdrawal response amplitude by small cardioactive peptide B was found to be dose dependent and reversible up to a concentration of 10(-9)M. At higher concentrations,the suppression tended to persist irreversibly. Small cardioactive peptide B stimulated adenylate cyclase activity in particulate fractions of both heart and gill tissues with an EC50 of 0.1 and 1.0 microM,respectively.[1] |
