Abstract

Starting from the antimalarial drugs chloroquine and hydroxychloroquine, we conducted a structural optimization on the side chain of chloroquine by introducing amino substituted longer chains thus leading to a series of novel aminochloroquine derivatives. Anti-infectious effects against SARS-Cov2 spike glycoprotein as well as immunosuppressive and anti-inflammatory activities of the new compounds were evaluated. Distinguished immunosuppressive activities on the responses of T cell, B cell and macrophages upon mitogen and pathogenic signaling were manifested. Compounds 9-11 displayed the most promising inhibitory effects both on cellular proliferation and on the production of multiple pro-inflammatory cytokines, including IL-17, IFN-γ, IL-6, IL-1β and TNF-α, which might be insightful in the pursuit of treatment for immune disorders and inflammatory diseases.

Keywords: Aminochloroquine; Anti-inflammatory; Antivirus; Choroquine; Cytokines.
