Ethisterone (Pregneninolone; 17α-Ethynyltestosterone) is a synthetic steroidal estrogen, is an orally active steroidal contraceptive agent. Ethisterone has almost no effect on the phagocytic activity of the reticuloendothelial system in male guinea pigs, while in utero exposure can induce abnormalities in the urogenital system of offspring.

体外実験

Ethisterone acts as an inducer of urogenital abnormalities, with in utero exposure linked to increased offspring urogenital abnormality prevalence, higher risk with earlier exposure onset^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

体内実験

Ethisterone (0.5 mg; i.m.; daily; 2-4 weeks) has little or no effect on the phagocytic activity of the reticulo-endothelial system in male guinea pigs^[1].

Animal Model:

Guinea pigs (Male)^[1]
Dosage:

0.5 mg
Administration:

i.m.; daily; 2 weeks; 4 weeks
Result:

Contained a moderate number of dye granules in macrophages of the spleen, liver, and lymph nodes.
Showed vital staining appearances closely resembling those of control animals.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
