| Description | Darbufelone (CI-1004) is a non-competitive dual inhibitor of PGF2α and LTB4. Dabfilon effectively inhibits PGHS-2 with a Ki of 10 μM and IC50s of 0.19 μM and 20 μM for PGHS-2 and PGHS-1. |
| Targets&IC50 | PGHS2:0.19 μM , PGHS1:20 μM |
| In vitro | Darbufelone (5 - 60 μM) increases the cell growth inhibitory effects in A549, H520 and H460 cell lines with IC50s of 20, 21 and 15 μM[2]. |
| In vivo | Darbufelone (80 mg/kg/day) decreases the tumor volumes in a time-dependent manner. Darbufelone (20 or 40 mg/kg/day) dos not show any significant inhibition of tumor weight. At necropsy, Darbufelone (80 mg/kg/day) reduces the tumor weight by 30.2%[2]. |
