代谢
醋酸十一酸睾酮可以通过5α-还原酶还原为二氢睾酮十一酸酯。在循环中,连接睾酮和十一酸的酯键被内源性的非特异性酯酶切割。像所有脂肪酸一样,十一酸侧链经历β-氧化,形成乙酰辅酶A(CoA),最终形成丙酰辅酶A。睾酮通过两条不同的途径代谢为各种17-酮类固醇,形成主要活性代谢物,雌二醇和二氢睾酮(DHT)。
Testosterone undecanoate can be reduced to dihydrotestosterone undecanoate via 5α-reductase. In the circulation, the ester bond linking testosterone to the undecanoic acid is cleaved by endogenous non-specific esterases. Like all fatty acids, the undecanoic side chain undergoes β-oxidation to form acetyl coenzyme A (CoA) and, finally, propionyl CoA. Testosterone is metabolized to various 17-keto steroids through two different pathways to form major active metabolites, estradiol and dihydrotestosterone (DHT).
