Biological Activity

Description Levonorgestrel (D-Norgestrel) is a female hormone that prevents ovulation.
Targets
Progesterone receptor [1]
In vitro Levonorgestrel suppresses the stimulation of progesterone secretion induced by oLH, dibutyryl-cAMP and Pregnenolone in rats luteal cells. [1] Levonorgestrel also inhibits constrictions evoked by either a high potassium (K(+)) solution or phorbol myristate acetate (PMA) in the absence and presence of extracellular calcium (Ca(2+)). Levonorgestrel depresses contractions evoked by Ca(2+) and reduces (45)Ca(2+) influx in depolarized veins. Levonorgestrel increases levels of cyclic AMP and inhibits PMA-induced activation of protein kinase C in veins. Levonorgestrel causes endothelium-independent relaxations of jugular veins via inhibition of Ca(2+) entry and of protein kinase Cactivation. [2] Levonorgestrel inhibition of both estrogen-induced pituitary weight increment and hyperprolactinemia is reduced by mifepristone, whereas Flutamide is unable to block Levonorgestrel effects [3]
In vivo Levonorgestrel down-regulates the mRNA expression of follicle-stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR), estrogen receptor (ER) β and progesterone receptor (PR) in the ovary, and ERα and PR in the uterus of Mongolian gerbils. [4] Levonorgestrel causes a significant upregulation of the mRNA expression of the gene encoding luteinising hormone β-subunit (lhβ) and the suppression of the mRNA expression of the gene encoding follicle-stimulating hormone β-subunit (fshβ) in the pituitary of both male and female roach. Levonorgestrel disrupts the reproductive system of pubertalroach by affecting the pituitary gonadotropin expression and the sex steroid levels in pubertal roach (Rutilus rutilus). [5]
