Invitro | Parbendazole is a tubulin destabilizer, with an EC50 of 530 nM, and can induce DNA damage[1]. Parbendazole (2-10 μM) inhibits the assembly of microtubules dose-dependently, with an IC50 of 3 μM. Parbendazole (2-20 μM)-treated cells show an complete absence of microtubules in Vero cells[2]. Parbendazole (up to 10 μM) inhibits the growth of CLd-AXE myxamoebae. Parbendazole (2-5 μM) potently inhibits tubulin purified from the wild-type myxamoebae[3]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||
