Coronaridine and conopharyngine exhibit central nervous system stimulant effects. In regular doses, conopharyngine has hypotensive properties, causes bradycardia and decreases body temperature. High doses of ibogaine, ibogamine and voacangine produce convulsions and asphyxia. Coronaridine showed diuresis and significant hypoglycaemic activity. It is an effective antifertility agent because of its oestrogenic activity. It also has leishmanicidal activity. Furthermore, apparicine, conopharyngine, coronaridine and perivine have local analgesic activity. The monomers apparacine, coronaridine and the dimers conodurine and gabunine showed significant cytotoxicity against P-388 lymphocytic leukaemia cell cultures. Conoduramine, conodurine and apparicine also showed moderate to strong antibacterial activity against several human pathogens, while apparicine also showed strong activity against type III poliovirus (HPV-3)[
