Cinanserin hydrochloride (SQ 10643) 是一种有效,选择性和高度亲和力的5-HT2受体拮抗剂,Ki为 41 nM。Cinanserin hydrochloride 对5-HT2的结合亲和力比对 5-HT1受体 (Ki为 3500 nM) 的结合亲和力高得多。Cinanserin hydrochloride 还是COVID-19 病毒的 3C 样蛋白酶 (3C-like proteinase) 的抑制剂,可大大减少体外的病毒复制。
生物活性 | Cinanserin hydrochloride (SQ 10643) is a potent, selective and highly affinity5-HT2receptorantagonist with aKiof 41 nM. Cinanserin hydrochloride has a much higher binding affinity for the5-HT2than for the5-HT1receptor(Kiof 3500 nM). Cinanserin is also an inhibitor of3C-like proteinaseof severe acute respiratory syndrome coronavirus and strongly reduces virus replication in vitro[1][2][3]. |

体外研究 (In Vitro) | Cinanserin/Cinanserin hydrochloride have binding affinity to SARS-CoV 3CLpro, HCoV-229E 3CLpro, with the KDvalues of 49.4 μM/78.0 μM for SARS-associated coronavirus (SARS-CoV) 3CLproand 18.2 μM/36.6 μM for human coronavirus 229E (HCoV-229E) 3CLpro[1]. The IC50values of Cinanserin and Cinanserin hydrochloride for inhibiting the catalytic activity of SARS-CoV 3CLproare calculated as 4.92 μM and 5.05 μM, respectively, The corresponding IC50values for HCoV-229E 3CLproare 4.68 μM and 5.68 μM. None of the compounds have inhibitory activity against HRV-14 3Cproat concentrations up to 200 μM[1].

体内研究 (In Vivo) | Cinanserin (5 mg/kg; intravenous injection; for 2 hours; male Wistar rats) treatment significantly reduces systemic burn edema to shamburn levels. Leukocyte-endothelial interactions are significantly reduced by administration of Cinanserin[2].
Animal Model: | Male Wistar rats (250 g) underwent thermal injury[2] | Dosage: | 5 mg/kg | Administration: | Intravenous injection; for 2 hours | Result: | Significantly reduced systemic burn edema to shamburn levels.. |
