Tariquidar 生物活性

靶点

  • P-gp

    P-gp, Kd:5.1 nM
描述 The multidrug resistance is an obstacle in the chemotherapy treatment (such as doxorubicin, vincristine, paclitaxel, TKIs) for many solid and haematological tumours. Many factors can cause the multidrug resistance. Among them, the overexpression of P-gp (ABCB1), of which vinblastine and paclitaxel is the substrate, on the surface of resistant cells is considered as a key factor mediating multidrug resistance. Thus, the increased bioavailable and brain accumulation of anticancer drugs can be achieved partially through inhibition of P-gp. Tariquidar is a potent P-gp transport modulator with IC50 value of 0.4μM, displaying specific high-affinity binding to P-gp with Kd of 5.1nM. The cellular study showed that the accumulation of vinblastine and paclitaxel can be increased in a dose-dependent manner by tariquidar with EC50 value of 487nM and 25.4nM, respectively, in CHrB30 cells, not mediated through competition for transport[1]. Co-administration of paclitaxel with tariquidar (p.o., 50mg/kg) led to a comparable increase and a long lasting 5-fold increase in the concentration of paclitaxel accumulation in the cytostatic in the brain of nude mice[2].
作用机制 Tariquidar can bind at a site which is distinct from the site of interaction of transport substrates and alter P-gp-mediated transport by affecting its rate of ATP hydrolysis.[1]
