Didesmethyl cariprazine is an orally active, BBB-permeable metabolite of Cariprazine (HY-14763). Didesmethyl cariprazine is a partial agonist at the D2 and D3 receptors, full agonist at the 5-HT1A receptor, and antagonist at the human 5-HT2B receptor (Ki: 1.41 nM (human D2L), 0.056 nM (human D3), 1.7 nM (human 5-HT1A), 0.52 nM (human 5-HT2B)). Didesmethyl cariprazine dose-dependently inhibits the spontaneous activity of rat midbrain dopaminergic neurons.

Description

Didesmethyl cariprazine is an orally active, BBB-permeable metabolite of Cariprazine (HY-14763). Didesmethyl cariprazine is a partial agonist at the D2 and D3 receptors, full agonist at the 5-HT1A receptor, and antagonist at the human 5-HT2B receptor (Ki: 1.41 nM (human D2L), 0.056 nM (human D3), 1.7 nM (human 5-HT1A), 0.52 nM (human 5-HT2B)). Didesmethyl cariprazine dose-dependently inhibits the spontaneous activity of rat midbrain dopaminergic neurons[1][2].

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.
