Cinanserin hydrochloride 1 Publications Verification SQ 10643	5-HT Receptor Influenza Virus	Infection Inflammation/Immunology
Cinanserin hydrochloride (SQ 10643) is a potent, selective and highly affinity 5-HT₂ receptor antagonist with a K_i of 41 nM. Cinanserin hydrochloride has a much higher binding affinity for the 5-HT₂ than for the 5-HT₁ receptor (K_i of 3500 nM). Cinanserin is also an inhibitor of 3C-like proteinase of severe acute respiratory syndrome coronavirus and strongly reduces virus replication in vitro ^[3].
