Abstract:
A process for preparing a 3-oxo-.DELTA..sup.1,4 -steroid comprises fermenting the corresponding 3-oxo-.DELTA..sup.4 -steroid, saturated in the 1,2-position, witih a living culture of Arthrobacter simplex in the presence of 0.04 g to 0.12 g of cobalt(II) ions per liter of culture broth.
Abstract:
17.beta.-Hydroxy-17.alpha.-methyl-5.alpha.-androstano[3,2-c]pyrazole 17-methyl ether is a very potent reversible male contraceptive which has a very low degree of androgenic side effects. Upon cessation of administration fertility promptly returns.
Abstract:
Radiolabeled steroid derivatives having the formula ##STR1## wherein St is a 6-dehydro derivative of a 3-oxo-4,5-dehydro steroid intended for radioimmunoassay, said steroid being saturated in the 1,2-position; R is hydrogen or alkyl of 1 to 3 carbon atoms; n is 0, 1, 2, 3 or 4; and the asterisk (*) indicates tagging with a radioisotope, are useful as tracers in radioimmunoassays. The unlabeled analogs can be coupled with an immunogenic carrier and used to induce antibody formation in animals.
Abstract:
2.alpha.-Cyano-3-oxosteroids having a 4.alpha.,5.alpha.-epoxy group and alkylated in the 4- and/or 6-position, useful as interceptive agents, are prepared by alkaline cleavage of the corresponding steroido[2,3-d]isoxazoles.
Abstract:
The present invention concerns derivatives of 19-oxygenated-androst-5-enes which are useful in the enhancement of libido and related psychic attitudes.
Abstract:
The present invention relates to a process for the synthesis of oxandrolone from mestanolone. The process comprises the steps of: (a) oxidizing mestanolone to form 17β-hydroxy-17α-methyl-5α-androst-1-en-3-one; (b) hydroxylating the 17β-hydroxy-17α-methyl-5α-androst-1-en-3-one to form 1α,2α, 17β-trihydroxy-17α-methylandrostan-3-one; (c) cleaving the 1α, 2α, 17β-trihydroxy-17αmethylandrostan-3-one to form 17β-hydroxy-17α-methyl-1-oxo-1,2,-seco-A-nor-5αandrostan-2-oic acid; and (d) reducing the 17β-hydroxy-17α-methyl-1-oxo-1,2,-seco-A-nor-5α-androstan-2-oic acid to form oxandrolone.
Abstract:
