A-349821 是一种组胺 H3 受体拮抗剂，被描述为用于体内受体占有率评估的放射性配体 ([3H]-A-349821)。在大鼠中，[3H]-A-349821 渗透到大脑中，在皮质中的含量高于小脑，表明选择性 H3 受体结合。其皮质占有率是可饱和的，与体外结合数据相关。对 ABT-239 和其他 H3 拮抗剂的抑制研究表明，受体占有率呈剂量依赖性降低，与临床前模型中与认知功效相关的血液水平相匹配。因此，[3H]-A-349821 可作为 H3 受体占有率的有效示踪剂，有助于 H3 受体拮抗剂的开发和临床解释。

生物活性

A-349821 is a histamine H3 receptor antagonist characterized as a radioligand ([3H]-A-349821) for in vivo receptor occupancy assessment. In rats, [3H]-A-349821 penetrated the brain, showing higher levels in the cortex compared to the cerebellum, indicating selective H3 receptor binding. Its cortical occupancy was saturable, correlating with in vitro binding data. Inhibition studies with ABT-239 and other H3 antagonists showed dose-dependent reductions in receptor occupancy, matching blood levels associated with cognitive efficacy in preclinical models. [3H]-A-349821 thus serves as a valid tracer for H3 receptor occupancy, aiding in the development and clinical interpretation of H3 receptor antagonists[1].

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.
