Description
Curator's Comment: description was created based on several sources, including: http://www.drugbank.ca/drugs/DB04881

Elacridar is an oral bioenhancer that targets multiple drug resistance in tumors. Elacridar is a strong and relatively specific inhibitor of P-gp and BCRP, two main efflux transporters. Development of elacridar is assumed to have been discontinued.

CNS Activity

Curator's Comment: Known to be CNS penetrant in mouse. Human data not available.

Sample Use Guides

The starting daily dose of GF120918 was 50 mg and was to be increased in subsequent cohorts until a steady state plasma level of 100 ng/ml was reached.
Route of Administration: Oral
In Caki-1 and ACHN cells, elacridar ( 2.5 μM) significantly inhibits the cell growth. The P-glycoprotein expression is found to be inhibited by 5 uM elacridar in all cell lines (786-O, ACHN, and Caki-1).
