What it is
Ropocamptide is a human cathelicidin that inhibits viral replication and while also playing a role in host defense against infection. The listed molecular formula is C205H340N60O53. PepGrades separately preserves the catalog category because a chemical identity record does not establish a use, outcome, or product quality.
This label describes the available research record, not whether the compound is safe or effective for an individual.
Research context
5 registered studies were found under this name in the current review. Each study still needs to be checked for the exact compound identity, population, endpoints, and results.
