Abstract: The invention provides corticosteroids that are chemically modified by covalent attachment of a water-soluble oligomer. A compound of the invention, when administered by any of a number of administration routes, exhibits different properties compared to the properties of the corticosteroid not attached to the water-soluble oligomer.

Abstract: The invention provides corticosteroids that are chemically modified by covalent attachment of a water soluble oligomer. A compound of the invention, when administered by any of a number of administration routes, exhibits a reduced biological membrane crossing rate as compared to the biological membrane crossing rate of the corticosteroid not attached to the water soluble oligomer.

Abstract: The present invention relates to processes for obtaining abiraterone and derivatives thereof, such as abiraterone acetate, by means of a Suzuki coupling through a steroid borate of general formula (IV) or a C—C coupling through a steroid hydrazone of general formula (II), as well as to intermediates useful in said processes.

Abstract: Novel benzoic acid hydrazones of 5?-androstan-3,17-dione have been prepared on the basis of steroidal tigogenin of the plant Yucca gloriosa. The hydrazones of the General Formula (I), General Formula (II) and General Formula (III) as shown in the accompanying FIGURE of the drawing are synthesized. The hydrazones have shown promising anti-T.B., anti-cancer and anti-HIV activity revealing immense potential as more efficacious, less toxic drugs with fewer undesirable side effects. They could also prove valuable in correcting hormonal abnormalities that cause severe health problems.

Abstract: Compounds represented by the following structural formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are as defined in the specification. The compounds are disclosed as useful in the treatment of various forms of cancer.

Abstract: The invention is drawn to a process for the preparation of a steroid of the formula ##STR1## wherein R.sub.1 is hydrogen or alkyl of 1 to 4 carbon atoms, R.sub.2 is alkyl of 1 to 4 carbon atoms and theo A, B, C, and D ring system has at least one double bond and is optionally substituted by at least one optionally protected hydroxy, optionally protected keto, halogen, alkyl and alkoxy of 1 to 4 carbon atoms, and alkenyl and alkynyl of 2 to 4 carbon atoms by reacting the corresponding 17-ketosteroid with a compound of the formula ##STR2## and then by reacting the resulting compound with an aryl sulfenyl halide. The intermediate produced then undergoes rearrangement followed by epimerization with a strong base to obtain a mixture of the corresponding sulfoxide diastereoisomers which is reacted with a thiophilic compound. The intermediate produced undergoes acid hydrolysis to provide the compound of formula I.
