NSC 23925B

NSC 23925B is a P-glycoprotein (P-gp) inhibitor, as well as the most biologically active isomer of NSC23925 (HY-19626), which reverses and prevents P-glycoprotein-mediated multidrug resistance in cancer cells. NSC 23925B shows weak inhibition against most CYP450 enzymes (IC₅₀ > 10 μM), and exhibits moderate inhibitory activity against CYP2B6 and CYP2D6 with IC₅₀ values of 8.589 μM and 1.407 μM, respectively. NSC 23925B can be used for the research of multidrug-resistant cancers.

All Cytochrome P450 Isoforms :

In Vitro

NSC 23925B potently reverses Pgp-mediated multidrug resistance (MDR) in multidrug-resistant human breast cancer and colon cancer cell lines^[1].
NSC 23925B inhibits Pgp-mediated chemoresistance in ovarian cancer cells and osteosarcoma cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

NSC 23925B (2.50-93.75 mg/kg; i.p.; i.v.; single dose) exhibits favorable pharmacokinetic profiles with high bioavailability, measurable plasma concentrations over 24 hours, and limited toxicity in male BALB/c mice, with a maximum tolerated dose of at least 68.80 mg/kg (i.p.) in males and 24.70 mg/kg (i.v.) in both sexes^[1].
NSC 23925B (2.50-47.20 mg/kg; i.p.; i.v.; single dose) exhibits favorable pharmacokinetic profiles with high bioavailability, measurable plasma concentrations over 24 hours, and limited toxicity in male Sprague-Dawley rats, with a maximum tolerated dose of at least 33.10 mg/kg (i.p.) and 38.80 mg/kg (i.v.) in males^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
