ACTH 11-24 acetate(4237-93-8 free base) (Adrenocorticotropic Hormone (11-24) acetate) is a fragment of adrenocorticotrophin, induces cortisol release. ACTH (11-24) has been identified as a competitive antagonist of ACTH (1-39) and ACTH (1-10) in isolated adrenal cells.
In vitro, ACTH (11-24) acts as an antagonist of adrenocorticotropic hormone receptor[1]. ACTH (11-24) induces cortisol secretion submaximally in freshly dispersed or cultured beef adrenal cortical cells. The maximal cortisol release by ACTH (11-24) is enhanced by forskolin but inhibited by calcium channel blockers[2].
In vivo, ACTH (11-24) blocks electroacupuncture (EA) anti-edema but not EA anti-hyperalgesia in rats[1].

ACTH 11-24 acetate(4237-93-8 free base) (Adrenocorticotropic Hormone (11-24) acetate) 是促肾上腺皮质激素的片段,可诱导皮质醇释放。 ACTH (11-24) 已被确定为分离的肾上腺细胞中 ACTH (1-39) 和 ACTH (1-10) 的竞争性拮抗剂。
在体外,ACTH (11-24) 作为肾上腺皮质激素受体的拮抗剂[1]。在新鲜分散或培养的牛肾上腺皮质细胞中,ACTH (11-24) 能次最大限度地诱导皮质醇分泌。ACTH (11-24) 引起的皮质醇最大释放量可被forskolin增强,但被钙通道阻断剂所抑制[2]。
在体内,ACTH (11-24) 在大鼠中阻断电针(EA)的抗水肿作用,但不影响EA的抗高敏反应[1]。
