Product Introduction

Bioactivity
Description
Levonorgestrel (D-Norgestrel) is a Progestin and Progestin-containing Intrauterine Device. The physiologic effect of levonorgestrel is by means of Inhibit Ovum Fertilization.
In vitro
Levonorgestrel significantly upregulates mRNA expression of the gene encoding luteinizing hormone beta subunit (lhβ) in both male and female cockroaches, while downregulating mRNA expression of the gene encoding follicle-stimulating hormone beta subunit (fshβ). Furthermore, in long-clawed ground squirrels, Levonorgestrel decreases the mRNA expression of ovarian follicle-stimulating hormone receptor, luteinizing hormone receptor, ovarian estrogen receptor β, and progesterone receptor, as well as the mRNA expression of ERα and PR in the uterus.
In vivo
Levonorgestrel elevates cyclic AMP levels in the veins and inhibits the activation of protein kinase C induced by PMA. It suppresses progesterone secretion in rat luteal cells, which is stimulated by oLH, dibutyryl-cAMP, and pregnenolone. Levonorgestrel also inhibits contractions induced by high potassium (K(+)) solutions or PMA in the presence and absence of extracellular calcium (Ca(2+)), effectuating endothelium-dependent relaxation through hindrance of calcium ion ingress and protein kinase C activation. Moreover, while the inhibitory effects of Levonorgestrel on estrogen-induced pituitary weight gain and hyperprolactinemia are attenuated by mifepristone, flunarizine does not block its effects.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
