Description：Protopine hydrochloride, an isoquinoline alkaloid, is a specific reversible and competitive inhibitor of acetylcholinesterase. Protopine hydrochloride exhibits anti-inflammation, anti-microbial, anti-angiogenic and anti-tumour activity.

In Vitro：Protopine (10-40 μM, 24 h-96 h) hydrochloride inhibits cell viability, migration, invasion and EMT process of liver carcinoma cells (HepG2, Huh7)[2].Protopine (10-40 μM, 24 h) hydrochloride induces apoptosis by increasing the expression of caspase-3 and caspase-9 in HepG2 and Huh7 cells, and inhibits the PI3K/Akt signaling pathway[2].Protopine (10-40 μM, 6 h) hydrochloride induces generation of ROS in HepG2 and Huh7 cells[2].Protopine (0-10 μg/mL) hydrochloride inhibits the uptake of serotonin transporter (SERT) in S6 cells and noradrenaline (NE) uptake in N1 cells[3].

In Vivo：Protopine (0.1 and 1 mg/kg, i.p.) hydrochloride alleviates Scopolamine (HY-N0296) (1 mg/kg)-induced memory impairment in mice[1].Protopine (5-20 mg/kg, i.v.) hydrochloride inhibits tumor growth and inhibits PI3K/Akt, and induces cleavage of caspase-3 in xenograft BALB/c mice (s.c. with HepG2 or Huh-7 cells)[2].Protopine (5-20 mg/kg, i.p.) hydrochloride shows antidepressant-like effect in mice HTR and TST tests[3].Protopine (1-4 mg/kg, i.p., once daily for 3 days) hydrochloride shows protective effect on the focal cerebral ischaemic induced injury in rats[4].
