Piribedil (Trivastan) is a dopamine D2 agonist, used in the treatment of Parkinson's disease.

Piribedil D8 is the deuterium labeled Piribedil, which is an agent of antiparkinsonian.

Methylatropine is an antagonist of muscarinic acetylcholine receptors (IC50= <0.1 nM in a radioligand binding assay using isolated porcine brain membranes) and a derivative of atropine .1,2It reduces acetylcholine-induced decreases in blood pressure in rats when administered intravenously with an ED50value of 5.5 μg/kg.2Methylatropine reduces salivation, induces mydriasis, and increases heart rate in dogs.3 1.Schmeller, T., Sporer, F., Sauerwein, M., et al.Binding of tropane alkaloids to nicotinic and muscarinic acetylcholine receptorsPharmazie50(7)493-495(1995) 2.Brezenoff, H.E., Xiao, Y.-F., and Vargas, H.A comparison of the central and peripheral antimuscarinic effects of atropine and methylatropine injected systemically and into the cerebral ventriclesLife Sci.42(8)905-911(1988) 3.Albanus, L.Central and peripheral effects of anticholinergic compoundsActa Pharmacol.

Piribedil Maleate is a direct agonist of dopamine that acts by showing selectivity for the D3 subtype.

Piribedil hydrochloride can be used in the parkinson's disease, circulatory disorders, cancers research. Piribedil hydrochloride inhibits MLL1 methyltransferase activity with EC50 value of 0.18 μM. Piribedil hydrochloride is a potent and orally active agonist of dopamine D2 and dopamine D3 as well as the antagonist of α2-adrenoceptors [1] [2] [3] [4].
