Conocarpan has antinociceptive effects. Conocarpan is quite active against S. aureus and B. subtilis with MIC of 6.25 micrograms/ml, it also shows activity against M. tuberculosis (MIC=15.6 ug/ml). Conocarpan shows considerable activity against epimastigote forms of T. cruzi, with 50% inhibition concentrations (IC50) of 8.0 microg/ml.
