Product Introduction
Bioactivity
名称
Piribedil hydrochloride
描述
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].
体外活性
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: MLL-r AML cells (THP-1 and MV4;11), non-MLL leukemia cell line (K562) Concentration: 0, 20, 40, 80 and 160 μM Incubation Time: 0-7 days Result: Inhibited the growth rate of the THP-1 and MV4;11 cells in a time-dependent manner. Western Blot Analysis [4] Cell Line: THP-1 and MV4;11 cells Concentration: 0, 20, 40, 80 and 160 μM Incubation Time: 4 days Result: Decreased the levels of H3K4me2 and H3K4me3 without affecting the methylation of other histones, such as H3K79, H3K36 and H3K27.
体内活性
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]. Animal Model: Rat model of Parkinson’s disease [2] Dosage: 5, 15, 40 mg/kg Administration: Intraperitoneal injection, administered 5 min before administration of L-DOPA. Result: Reduced turning behaviour and AD (axial dystonia), OD (orolingual dyskinesia) and FD (forelimb dyskinesia) at 5 and 40 mg/kg. Increased LD (locomotive dyskinesias) at the 40 mg/kg. Animal Model: Adult common marmosets [3] Dosage: 4-5 mg/kg Administration: Oral gavage, daily for 2 weeks Result: Increased vigilance and alertness and reversed the downregulation of preprotachykinin mRNA induced by MPTP in rostral and caudal striatum.
