Introduction of 135729-62-3 :

Palonosetron hydrochloride is a 5-HT3 antagonist primarily used to prevent acute, delayed, and overall chemotherapy-induced nausea and vomiting. In addition, Palonosetron hydrochloride exhibits moderate anti-flavivirus activity and potent anti-Zika virus activity in mammalian cells. Palonosetron hydrochloride also possesses antidepressant activity[1][2][3][4]. In Vitro:Palonosetron (10 nM, 2 hours) hydrochloride inhibits the enhancement effect of 5-HT on substance P (SP)-induced calcium release in NG108-15 cells, increasing the EC50 of SP from 0.62 µM to 3.7 µM[6].
In Vivo:Palonosetron (0.05 mg/kg, i.p., single dose) hydrochloride significantly reduces immobility in Swiss albino mice, demonstrating potential antidepressant activity[5].
alonosetron (30-300 µg/kg, i.v., single dose) hydrochloride dose-dependently inhibits SP-mediated neuronal responses in the Cisplatin (HY-17394)-induced rat emesis model, indicating its impact on neurotransmission[6].
