Dutasteride-¹³C,¹⁵N,d  (Synonyms: 度他雄胺-¹³C,¹⁵N,d; GG 745-¹³C,¹⁵N,d; GI 198745-¹³C,¹⁵N,d)

Dutasteride-¹³C,¹⁵N,d is ¹⁵N and deuterated labeled Dutasteride (HY-13613). Dutasteride (GG745) is a potent inhibitor of both 5α-reductase isozymes. Dutasteride may possess off-target effects on the androgen receptor (AR) due to its structural similarity to DHT^[1].

氢、碳和其他元素的稳定重同位素已被纳入药物分子中，主要作为药物开发过程中定量的示踪剂。氘化引起了人们的关注，因为它可能影响药物的药代动力学和代谢谱^[1]。

GG745 has a terminal half-life of approximately 240 hr, and single doses of >10 mg decreased DHT levels significantly more than did single 5-mg doses of finasteride^[4].
In placebo treated men without prostate cancer there was an 8.3% median increase in PSA at month 24 compared with -59.5% in those who received dutasteride, using doubled values to correct for dutasteride treatment^[5].
Toxicity: Dutasteride may affect male fertility and steroid hormone dynamics. Therefore, a 21-day reproduction study was conducted to determine the effects of dutasteride (10, 32 and 100 μg/L) on fish reproduction. Exposure to dutasteride significantly reduced fecundity of fish and affected several aspects of reproductive endocrine functions in both males and females^[6].
