Popis: All- trans retinoic acid (all- trans RA), the active metabolite of vitamin A, has been demonstrated to be an efficient alternative to chemotherapy in the treatment of acute promyelocytic leukemia (APL), the AML 3 subtype of the FAB cytological classification. Complete remission is obtained by inducing terminal granulocytic differentiation of the leukemic cells. To study all- trans RA pharmacokinetics in patients with APL, a rapid, precise and selective high-performance liquid chromatographis (HPLC) assay was developed. This method is easy and shows good repeatability (C.V. = 8.41–12.44%), reproducibility (C.V. = 9.19–14.73%), accuracy (C.V. = 3.5–11%) and sensitivity with a detection limit of 5 pmol/ml. The analysis is performed using normal-phase HPLC in an isocratic mode with UV detection after solid-phase extraction on octadecyl (C 18 ) columns. The mobile phase is hexanedichloromethane-dioxane (78:18:4, v/v) containing 1% acetic acid.
