Biological Activity for Loperamide hydrochloride

Loperamide hydrochloride is a high affinity μ-opioid receptor agonist with peripheral selectivity (K_i values are 2, 48 and 1156 nM for μ-, δ- and κ-opioid receptors respectively). Antidiarrhoeal and antihyperalgesic agent. Also a Ca²⁺ channel blocker; at low micromolar concentrations it blocks broad spectrum neuronal HVA Ca²⁺ channels and at higher concentrations it reduces Ca²⁺ flux through NMDA receptor operated channels. Inhbits replication of MERS-CoV and SARS-CoV in vitro.
