Many different derivatives have been isolated from plants. For example, many water-lilies (Nymphaea species) produce aporphine alkaloids such as nymphaeine, nymphaline, nupharine, alfa- and beta-nupharidine.
In vitro tests of some aporphine derivatives isolated from Cassytha filiformis, namely actinodaphnine, cassythine, and dicentrine, showed antiparasitic activity against Trypanosoma brucei. Investigation of possible mechanisms revealed that the compounds bind to DNA and act as intercalating agents, besides inhibiting topoisomerase activity.
(R)-Aporphine is a dopamine receptor D1 antagonist (Edit: this compound is an AGONIST, the previous writer incorrectly interpreted the source) with a Ki of 717 nM and a dopamine receptor D2 antagonist with a Ki of 527 nM. Aporphine and its related alkaloids bulbocapnine, boldine, glaucine, and corytuberine are antipsychotic, exert naloxone-reversible antinociceptive activity, and with the exception of corytuberine are anticonvulsant. Some derivatives of aporphine such as (S)-(+)-N-propylnorapomorphine have potential as low side effect profile antipsychotics. (S)-(+)-N-Propylnorapomorphine is highly selective for meso-limbic dopaminergic tracts and function as efficacious partial agonists, with no elevation in prolactin.
Apomorphine is a type of dopaminergic agonist, a morphine derivative which primarily affects the hypothalamic region of the brain. Drugs containing this substance are sometimes used in the treatment of Parkinson's disease or erectile dysfunction. In higher doses it is a highly effective emetic. Apomorphine Hydrochloride is the hydrochloride salt form of apomorphine, a derivative of morphine and non-ergoline dopamine agonist with high selectivity for dopamine D2, D3, D4 and D5 receptors. Apomorphine hydrochloride acts by stimulating dopamine receptors in the nigrostriatal system, hypothalamus, limbic system, pituitary gland, and blood vessels. This enhances motor function, suppresses prolactin release, and causes vasodilation and behavioral effects. Apomorphine hydrochloride is used in the treatment of Parkinson's disease and erectile dysfunction. In addition, apomorphine hydrochloride acts on the chemoreceptor trigger zone and is used as a central emetic in the treatment of drug overdose.
