T-0632 是一种的 CCK A 受体拮抗剂,其在体外研究中表现出显著的药理特性。T-0632 通过竞争性抑制 [125I]CCK-8 与大鼠胰腺 CCK A 受体的结合,K_i 值为 0.24 nM,显著低于对豚鼠 CCK B 受体的 K_i 值。T-0632 在抑制 CCK-8 刺激的胰腺酶释放方面具有更高的选择性,IC_50 值为 5.0 nM,相比于 L-364,718 和 loxiglumide 更具优势。在兔胆囊平滑肌中,T-0632 和 loxiglumide 的拮抗作用是可逆的,而 L-364,718 显示出持久的抑制效果。这些结果表明,T-0632 是一种高效、可逆且更具选择性的 CCK A 受体拮抗剂。

生物活性

T-0632 is a CCK A receptor antagonist that exhibits significant pharmacological properties in in vitro studies. T-0632 competitively inhibits the binding of [125I]CCK-8 to rat pancreatic CCK A receptors with a K_i value of 0.24 nM, which is significantly lower than the K_i value for guinea pig CCK B receptors. T-0632 has higher selectivity in inhibiting CCK-8-stimulated pancreatic enzyme release, with an IC_50 value of 5.0 nM, which is more advantageous than L-364,718 and loxiglumide. In rabbit gallbladder smooth muscle, the antagonistic effects of T-0632 and loxiglumide are reversible, while L-364,718 shows a persistent inhibitory effect. These results indicate that T-0632 is a highly potent, reversible and more selective CCK A receptor antagonist.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
