A 3H+-release method has been developed for the assay of β-hydroxylation of the adrenolytic drug mitotane. β-3H-mitotane was synthesized by the reduction of 1-(2-chlorophenyl)-1-(4-chlorophenyl)-2,2,2-trichloroethane by an aluminium-Hg2Cl2 couple in the presence of 3H2O. For β-hydroxylation of mitotane, the 3H+-release assay is more efficient and sensitive than a method utilizing 14C-mitotane and chromatographic separation of metabolites by HPLC. The 3H+-release assay has been used to evaluate the ability of adrenal tumors to metabolize mitotane via the β- hydroxylation route.
β-3H-米托坦是由 1-(2-氯苯基)-1-(4-氯苯基)-2,2,2-三氯乙烷在 3H2O 存在下通过铝-Hg2Cl2 对偶还原合成的。与利用 14C-itotane 和 HPLC 色谱分离代谢物的方法相比,3H+ 释放测定法在米托坦的β-羟基化方面更有效、更灵敏。3H+ 释放测定法已被用于评估肾上腺肿瘤通过 β- 羟基化途径代谢米托坦的能力。
