| In vitro study | Jatrorrhizine has antiplasmodial and antiamoebic activity, it against Plasmodium falciparum and E. histolytica with IC 50 values of 3.15 and 82.7 µM, respectively.The hOCT2 (organic cation transporter 2), hOCT3, and PMAT (plasma membrane monoamine transporter) are capable of transporting monoamine neurotransmitters in the brain. Jatrorrhizine has the inhibitory potency of jatrorrhizine on 5-HT and NE uptake in hOCT2-, hOCT3-, and PMAT-transfected cells. Jatrorrhizine strongly inhibits PMAT-mediated MPP + uptake with an IC 50 value of 1.05 μM and reduces 5-HT and NE uptake mediated by hOCT2, hOCT3, and hPMAT with IC 50 values of 0.1-1 μM (for OCT2 and OCT3) and 1-10 μM (for PMAT).Clearance of neurotransmitters released into the synaptic cleft is defined by two distinct processes. Uptake-1, the common target of current applied antidepressants, is comprised of the serotonin transporter (SERT), the “SERT”, had a high affinity but low capacity to take up [3H]5-HT. Uptake-2 transporters are an important supplementary regulation system in monoamine clearancethought to be the “NET”, has low affinity but high capacity to take up [ 3 H]5-HT into brain slices. Jatrorrhizine significantly inhibited 5-HT and NE uptake in synaptosomes at 25 μM and 50 μM. |

| biological activity | jatrorhizine chloride is an alkaloid isolated from Coptis chinensis, anti-Plasmodium and antioxidant activity. Jatror Rhizine chchloride is a potent, orally active inhibitor of acetylcholinesterase (AChE) (IC50=872 nM) with 115-fold selectivity for BuChE. Jatrorhizine chchloride reduces the uptake of serotonin (5-HT) and norepinephrine (NE) by inhibiting the activity of uptake-2 transporter. |
