| Description | Ritanserin (R 55667) is a long-acting, highly potent, relatively selective, orally bioavailable 5-HT2 receptor antagonist with an IC50 of 0.9 nM. |
| Targets&IC50 | α2-adrenoceptor:150 nM, H1:35 nM, α1-adrenoceptor:97 nM, 5-HT2:0.9 nM, D2:70 nM |
| In vitro | METHODS: AML cell lines Kasumi-1 and KG-1α were treated with Ritanserin (R 55667) (10, 20, 30, 40, 50, 60 μM), and cytotoxicity was determined by CCK-8. RESULTSRitanserin (R 55667) significantly reduced the proliferation activity of AML cells in a dose-dependent and time-dependent manner. [1] Ritanserin (R 55667) has low activity against multiple receptors, including histamine-H1 (IC50, 35 nM), dopamine-D2 (IC50, 70 nM), adrenergic-α1 (IC50, 97 nM), and adrenergic-α2 receptors (IC50, 150 nM).[2] |
