| Bioactivity | Piribedil hydrochloride is a potent and orally active dopamine D2 and dopamine D3 agonist. Piribedil hydrochloride is also a α2-adrenoceptors antagonist. Piribedil hydrochloride can inhibit MLL1 methyltransferase activity (EC50: 0.18 μM). Piribedil hydrochloride has the potential for the research of parkinson's disease, circulatory disorders, cancers[1][2][3][4]. |
| Invitro | Piribedil hydrochloride (0-160 μM, 7 days) specifically inhibits MLL1 methyltransferase activity and selectively suppresses MLL-r cell proliferation[4].Piribedil hydrochloride (0-160 μM, 4 days) selectively decreases the H3K4 methylation in MLL-r cells (THP-1 and MV4;11), by disturbing the MLL1-WDR5 interaction[4].Piribedil hydrochloride (0-160 μM, 4 days) induces cell-cycle arrest, apoptosis and differentiation in MLL-r cells (THP-1 and MV4;11)[4]. Cell Proliferation Assay[4] Cell Line: |
| In Vivo | Piribedil hydrochloride (intraperitoneal injection, 5, 15, 40 mg/kg ) alleviates the L-DOPA-induced dyskinesias in rats model of Parkinson’s disease[2].Piribedil hydrochloride (oral gavage, 4-5 mg/kg, daily for 2 weeks) increases locomotor activity and reversal of motor deficits in adult common marmosets[3].Piribedil hydrochloride (oral gavage, 150 mg/kg, daily for 21 days) inhibits MLL-r tumor growth and decreases the expression of MLL1 target genes in MV4;11 tumor xenografts[4].
