- Piperine exhibits antiviral effects against SARS-CoV-2 and other viruses like MERS-CoV and HCV.

## Abstract

Piperine is an alkaloid found in plants of the genus Piper, and particularly in P. nigrum. This compound has been under extensive research lately for its antimicrobial, antiviral, and also anti-inflammatory, anti-oxidant, anticancer, and positive metabolic properties. Regarding its antibacterial applications, current data show that piperine is effective against Bacillus sphaericus, Bacterioides fragilis, Escherichia coli, Mycobacterium tuberculosis, Staphylococcus aureus, Streptococcus mutans, Pseudomonas aeruginosa, and Vibrio cholerae; its antifungal potency is exerted against Candida albicans and members of the Aspergillus family; antiviral activity has been documented against MERS-CoV, SARS-CoV2, EBOV, DENV, HCV, ZKV, and HPIV; and antiparasitic activity against Leishmania spp., Plasmodium spp., Trichomonas vaginalis, and Trypanosoma spp. While such applications are promising, more research is required to elucidate the mechanisms of action and to discover new ways of administration.
