Win 18446 is an orally active testes-specific enzyme ALDH1a2 inhibitor, with an IC50 of 0.3 μM. Win 18446 reversibly inhibits spermatogenesis in many species and inhibits Retinoic acid biosynthesis from Retinol (B1342) within the testes.
体外研究
WIN 18446 (1 μM, 24 h) is able to suppress Stra8 expression in whole-testes cultures that contained both germ and somatic cells.
RT-PCR
Cell Line:
Testes were collected from 2-dpp mice.
Concentration:
1 μM.
Incubation Time:
24 h.
Result:
Results in a VAD-like phenotype in the testis.
Alone or in combination with ROL significantly reduced Stra8 expression.
体内研究
Win 18446 (200 mg/kg, Orally for 4, 8, and 16 weeks) significantly reduces intratesticular concentrations of retinoic acid, severely impaired spermatogenesis, and caused infertility.
Animal Model:
Six-month-old male New Zealand white rabbits.
Dosage:
200 mg/kg.
Administration:
Orally for 4, 8, and 16 weeks.
Result:
Resulted in marked suppression of testicular weight over time.
Dramatically suppressed spermatogenesis.
Significantly reduces intratesticular concentrations of retinoic acid and Stra8 expression and very severely suppresses spermatogenesis and fertility.
