| | FSH RECEPTOR-BINDING INHIBITOR FRAGMENT (BI-10) Usage And Synthesis |
| Uses | FSH receptor-binding inhibitor fragment(bi-10) is a potent FSH antagonist. FSH receptor-binding inhibitor fragment(bi-10) blocks the binding of FSH to FSHR, and alteres FSH action at the receptor level. FSH receptor-binding inhibitor fragment(bi-10) results in the suppression of ovulation and causes follicular atresia of mice. FSH receptor-binding inhibitor fragment(bi-10) has the potential for utilizing to restrain the carcinogenesis of ovarian cancer by down-regulating overexpression of FSHR and ERβ in the ovaries[1]. | | in vivo | FSH receptor-binding inhibitor fragment(bi-10) (10, 20, 30, 40 mg/kg; Intramuscularly injection; once a day for five consecutive days) with high dose (30 mg/kg to 40 mg/kg) can suppress ovarian and follicular development, and attenuate expression levels of ERβ and FSHR mRNAs and proteins in the ovaries, additionally inhibit E2 production[1]. | Animal Model: | Prepuberty Kunming female mice of 21-days old and body weight of 22.3±1.52g[1] | | Dosage: | 10, 20, 30, 40 mg/kg | | Administration: | Intramuscularly injection; once a day for five consecutive days | | Result: | Could attenuate FSH promoting effect on the follicular development, resulting in the poor maturation of ovarian follicles.
High dose (40mg/kg) treatment blocked the follicle development of mice.
High dose of FRBI (40mg/kg) treatment blocked the follicle development of mice.
