Melengestrol acetate

Description:

Melengestrol acetate (CAS 2919-66-6) is a synthetic progestin, primarily used in veterinary medicine, particularly for controlling estrus in livestock and as a growth promoter in certain animal species. It is a white to off-white crystalline powder that is poorly soluble in water but soluble in organic solvents such as ethanol and acetone. The compound mimics the action of natural progesterone, binding to progesterone receptors and influencing various physiological processes, including reproductive functions. Melengestrol acetate is characterized by its stability under normal storage conditions, but it should be kept away from light and moisture to maintain its efficacy. In terms of safety, it is essential to handle this substance with care, as it may have hormonal effects and potential environmental impacts if not managed properly. Its use in food-producing animals is regulated, and it is important to adhere to withdrawal times to ensure that residues do not enter the human food supply.

Melengestrol acetate is a synthetic progesterone that has been used in the treatment of various diseases in humans and animals. It has been shown to have a protective effect on the ovaries, bowel disease, and infectious diseases. Melengestrol acetate also has estrogenic effects, which may be due to its ability to stimulate ovarian activity and estrus. The drug is metabolized into melengestrol and estradiol benzoate. It has been shown to have physiological effects on energy metabolism, 3T3-L1 preadipocytes, and trenbolone.
