| Description | TTT-28 is a thiazole-valine peptidomimetic and a selective ABCB1 (P-gp/MDR1) inhibitor with high efficacy and low toxicity, reversing ABCB1-mediated Multidrug resistance (MDR) by selectively blocking the efflux function of ABCB1. |
| In vitro | In drug selected SW620/Ad300 cells, TTT-28 (0-100?μM; 72 hours) reverses ABCB1-mediated MDR and transfected HEK293/ABCB1 cells(IC50s of TTT-28 in CCD-18Co, SW620 and SW620/Ad300 cells are 213.4±11.0 μM, 89.4±3.9 μM and 92.0±5.0?μM, respectively). TTT-28 (10 μM; 2 hours) raises the ABCB1-mediated MDR and increased the accumulation of [3H]-paclitaxel in ABCB1 overexpressing cells. TTT-28 (10 μM; 0-72 hours) does not interfer with the expression level and localization of ABCB1, it results from blocking the efflux function of ABCB1. TTT-28 (0-40?μM; 2 hours) interacts at the drug-substrate-binding site and actives the ATPase activity of ABCB1 in a concentration-dependent fashion. |
| In vivo | TTT-28 (deliver orally; 30 mg/kg; every 3rd day; 18 days) enhances the anticancer activity of paclitaxel by inhibiting the efflux function of ABCB1, thereby increasing paclitaxel's suppression of SW620/Ad300 tumor growth and promoting apoptosis. |
