nerispirdine

Nerispirdine is a biochemical that inhibits batrachotoxin binding to voltage-dependent sodium channels.

BPR1K653 is a potent Aurora kinase inhibitor with potential anticancder activity. BPR1K653 specifically inhibited the activity of Aurora-A and Aurora-B kinase at low nano-molar concentrations in vitro. BPR1K653 was potent in targeting a variety of cancer cell lines regardless of the tissue origin, p53 status, or expression of MDR1. At the cellular level, BPR1K653 induced endo-replication and subsequent apoptosis in both MDR1-negative and MDR1-positive cancer cells. Importantly, it showed potent activity against the growth of xenograft tumors of the human cervical carcinoma KB and KB-derived MDR1-positive KB-VIN10 cells in nude mice. Finally, BPR1K653 also exhibited favorable pharmacokinetic properties in rats., BPR1K653 is a promising anti-cancer compound that has potential for the management of various malignancies, particularly for patients with MDR1-related drug resistance after prolonged chemotherapeutic treatments.

Nerispirdine is a acetylcholine release enhancer, sodium channel blocker and K(V) 2.1 channel blocker. Nerispirdine inhibits voltage-dependent Na(+) channel currents recorded from human SH-SY5Y cells with an IC(50) of 11.9 micromol L when measured from a
