Approaches to improve the solubility and availability of progesterone biotransformation by Mucor racemosus

Substrate solubility in steroid biotransformation is critical for improving the biotransformation of hydrophobic substrates. The present investigation describes the effect of some organic solvents, polyoxyethylene sorbitan monooleate (Tween 80; surfactant

Pharmaceutical composition and process of treatment

A process for alleviating proliferative skin diseases such as psoriasis, atopic dermatitis, etc. comprising administering to humans, or domesticated animals, topically and/or systemically a composition comprising a pharmaceutical carrier and at least one active compound selected from the groups, substituted alkyl zanthines, tricyclic antidepressants, organic nitrates, antihypertensives, anti-asthma agents and central nervous system depressants and combinations of certain compounds from specifically named groups of compounds.

Selenium-75 steroids

Novel dimeric and monomeric selenium-75 derivatives of steroids are made by reacting a keto steroid with selenium-75 dioxide or selenious acid-Se75. The resulting diselenide dimers can be converted into monomeric compounds by the use of a cleaving reagent followed by an alkylating agent. The compounds are useful in saturation analyses such as radioimmunoassays.
