Uses

4-Hydroxytestosterone is an anabolic steroid and does not have any therapeutic indication. 4-Hydroxytestosterone is metabolite of the aromatase inhibitor Formestane (F692250). 4-Hydroxytestosterone co ncentration in the urine can be used as a biomarker for steroid misuse. Controlled Substance.

C-19 steroids for cosmetic uses

The present invention relates to novel uses of C-19 steroid compounds, in particular C-19 steroids having an androsten-17-(OR 4 )-3-one structure for cosmetic and further uses, wherein R 4 is hydrogen or an unsubstituted or substituted alkyl, aryl, acyl or any group leading to hydroxyl upon biological metabolization or chemical deprotection. The present invention particularly relates to selected C-19 steroids displaying properties of high binding affinity to androgen receptor to block dihydotestosterone from binding, while at the same time providing anabolic effects, which is useful for certain applications, particularly for influencing or controlling problems of the skin and its skin-associated body structures like cellulite, wrinkles, adipose fat tissues, hair follikles or hair growth; for influencing or controlling gland function and activity such as the sebaceous gland and other glands affecting the skin and/or perspiration. The present invention also describes a composition comprising a combination of such a compound and dimethyl isosorbide.

Practical preparation of diosphenols by ring opening of α,β-epoxyketones catalyzed by silica gel supported acids

The mixed acid (H2SO4-HOAc) catalyzed ring opening of α,β-epoxyketone was the most used method for the preparation of diosphenols, but it seriously suffered from poor yields and tedious workup operations. By using silica gel supported mixed acid (H2SO 4-HOAc), a variety of α,β-epoxyketones were converted into the corresponding diosphenols in unprecedented high yields within a few minutes.
