Verapamil (CP-16533-1) is a calcium channel blocker and an orally active and effective inhibitor of P-gp. Verapamil inhibits CYP3A4 and can be used in studies about the treatment of high blood pressure, heart arrhythmias, and angina research.

Piperine (Bioperine) , a alkaloid, has been used in trials studying the treatment of multiple myeloma and deglutition disorders.

Selamectin (UK-124114) is a macrocyclic lactone derivative of ivermectin, an anthelmintic that potentiates glutamate- and GABA-gated chloride channel opening in nematodes. In an H. contortus larval development assay, selamectin (0.1 μg/ml) shows the effect of growth inhibition.

Zamicastat (BIA 5-1058) is an inhibitor of dopamine β-hydroxylase (DBH) and a concentration-dependent dual inhibitor of P-gp and BCRP, with IC50 values of 73.8 μM and 17.0 μM, respectively.

Glibenclamide (Glyburide) is an antidiabetic sulfonylurea derivative with actions similar to those of chlorpropamide.

(20S)-Protopanaxadiol (20-Epiprotopanaxadiol) (20-Epiprotopanaxadiol), an apoptosis inducer, is an aglycon metabolic derivative of the protopanaxadiol-type ginseng saponin.

1. Isosinensetin (6-Demethoxynobiletin) shows antioxidant and HIV-1 protease inhibiting activities.

Voacamine (Voacanginine) is an indole alkaloid. Voacamine exhibits potent cannabinoid CB1 receptor antagonistic activity. Voacamine also inhibits P-glycoprotein (P-gp) action in multidrug-resistant tumor cells.Voacanginine may have rhythmic effects.

Coniferyl ferulate is a strong inhibitor of glutathione S-transferase (GST) isolated from Radix Angelicae sinensis. It shows strong inhibition of human placental GST (IC50: 0.3 μM). It also reverses multidrug resistance and downregulates P-glycoprotein.

Solamargine (δ-Solanigrine) is a major steroidal alkaloid glycoside extracted from a traditional Chinese medicine herb, Solanum nigrum L. (SNL); has been shown to inhibit growth and induce apoptosis of various cancer cells.

Zosuquidar trihydrochloride (LY-335979 trihydrochloride) is a potent modulator of P-glycoprotein-mediated multi-drug resistance with Ki of 60 nM. Phase 3.

Tariquidar (XR9576)(Kd=5.1 nM) is a specific and effective non-competitive inhibitor of P-glycoprotein. It can reverse drug resistance in MDR cell Lines.

Ibutilide Fumarate (U70226E) is the fumarate salt form of ibutilide, a class III antiarrhythmic agent. Ibutilide exerts its effect by activating a slow, inward, predominately sodium current rather than by blocking outward potassium currents. This results in prolongation of atrial and ventricular action potential duration and refractory periods. Ibutilide slightly decreases the sinus rate and atrioventricular (AV) conduction and produces a dose-related prolongation of the QT interval.

Trifluoperazine (trifluoroperazine) is a Dopamine D2 receptor inhibitor(IC50 : 1.2 nM), and Treatment of schizophrenia.

Encequidar (HM30181A) is a potent and selective P-glycoprotein inhibitor.
