Clomiphene
Based on 5 publication(s) in Google Scholar
Clomiphene (Clomifene; (Z/E)-Enclomiphene; (Z/E)-Enclomifene) is an orally active ovulation-inducing agent. Clomiphene binds to hypothalamic estrogen receptors to elevate FSH levels, and exhibits antiestrogenic or estrogenic properties. Clomiphene can induce erturbations during meiotic maturation and cytogenetic abnormalities in mouse oocytes. Clomiphene ameliorates memory impairment in PCOS models. Clomiphene mobilizes cytosolic calcium and reduces viability in prostate cancer cells. Clomiphene can be used for the research of polycystic ovary syndrome (PCOS) and prostate cancer.

Clomiphene (citrate) (1.0-5.0 μg/mL; 18 h) significantly increases hyperploidy and diploidy in cultured mouse germinal vesicle-stage oocytes, while reducing the proportion of metaphase I oocytes, indicating accelerated oocyte maturation[1].
Clomiphene (citrate) (10-50 μM) increases cytosolic free calcium levels in PC3 human prostate cancer cells with an EC50 of approximately 30 μM[4].
Clomiphene (citrate) (50 μM; 2-30 min) induces time-dependent mild cytotoxicity in PC3 human prostate cancer cells, reducing viability by 10-50% over 2-15 minutes of incubation with no further decrease after 15 minutes[4].

Cell Line:PC3 human prostate cancer cells
-
Concentration:50 μM
-
Incubation Time:2 min; 5 min; 10 min; 15 min; 20 min; 30 min
-
Result:Reduced cell viability in a time-dependent manner: 2 minutes of incubation reduced viability by 10%, 15 minutes of incubation reduced viability by 50%, and extending incubation to 30 minutes did not further reduce viability.
Clomiphene (citrate) (1 mg/kg; p.o.; daily; 15 days) improves spatial and non-spatial memory impairment, restores reproductive hormone levels, increases serum antioxidant enzyme concentrations, and downregulates prefrontal cortex AchE gene expression in Letrozole (HY-14248)-induced PCOS rats, but does not reduce anxiety-like behavior[2].
Clomiphene decreases serum gonadotropin levels and reduces testosterone secretion in rats[4].

Animal Model:ICR (female, 8-12 weeks, 25-34 g, ovarian stimulation with PMSG and hCG)[1]
-
Dosage:25, 50, 100 mg/kg
-
Administration:i.p.; 3 doses over 4 hours
-
Result:Increased hyperploidy to 1.5% (4 of 265 analyzed oocytes) and reduced average number of ovulated oocytes per mouse to 20.5 at 100 mg/kg.
Increased premature centromere separation to 5.0% (15 of 300 analyzed oocytes) and reduced average ovulated oocytes per mouse to 35.0 at 25 mg/kg.
Increased premature centromere separation to 3.6% (12 of 329 analyzed oocytes), increased single unpaired chromatids to 1.8% (6 of 329 analyzed oocytes), and reduced average ovulated oocytes per mouse to 37.7 at 50 mg/kg.
-
Animal Model:Wistar (female, 190-210 g, Letrozole-induced PCOS)[2]
-
Dosage:1 mg/kg
-
Administration:p.o.; daily; 15 days
-
Result:Significantly increased spontaneous alternation performance count and percentage in the Y maze compared to PCOS-only rats.
Increased serum superoxide dismutase (SOD) and catalase concentrations compared to PCOS-only rats.
Showed weak non-significant reduction in serum interleukin-1β (IL-1B) levels compared to PCOS-only rats.
Reversed upregulated acetylcholine esterase (AchE) gene expression in the prefrontal cortex compared to PCOS-only rats.
Reduced follicle-stimulating hormone (FSH) to 0.31 mIU/mL, reduced luteinizing hormone (LH) to 3.14 mIU/mL, increased estradiol to 27.68 ng/mL, and reduced testosterone to 0.28 ng/mL compared to PCOS-only rats.
Did not reduce anxiety-like behavior, as anxiety index values remained statistically high compared to control rats.
