Preparation Method |
The inhibitory activities of HM30181 were measured using the ATPase assay kit. The purified membrane vesicles were diluted to 0.1 µg/µL with assay mix and a 40-µL volume of diluted membrane suspension was loaded into each well of a 96-well microplate. One µL of the tested compound dissolved in dimethylsulfoxide (DMSO) with or without Na-orthovanadate (600 mM) was added to the membrane suspension. The same volume of DMSO was added to the control wells. The mixtures were pre-incubated at 37¡栦or 10 min and the reaction was started by addition of 10 µL Mg-ATP (200 mM). After a 10-min incubation at 37¡欠the inorganic phosphate (Pi) released was determined colorimetrically. The absorbance at 600 nm was read in a microplate reader, and the concentration of liberated Pi was calculated from the calibration curve. |

HM30181 mesylate salt, a tetrazole derivative, is known as a P-glycoprotein inhibitor that has inhibitory activities on multidrug resistance in cancer cells[1,5]. HM30181 has a strong inhibitory effect on MDR1-mediated paclitaxel transport in membrane vesicles. The IC50 value of HM30181 is 0.63 nM[2].
HM30181(10-10M-10-4M;5 min; 37¡橠is an effective inhibitor of MDR1in 293FRT-MDR1 cells[2]. The survival inhibition rates of 0.1 nM and 1 nM Encequidar (HM30181) were 20% and 42% respectively, at 100 nM and 1000 nM NSC 125973[3].
HM30181 can significantly improve the bioavailability of oral paclitaxel. In the xenograft model in nude mice, oral co-administration of paclitaxel and HM30181 effectively inhibited tumor growth [2,4].
