摘要:
Certain benzopyran antiestrogens are disclosed for treating estrogen sensitive diseases such as breast cancer. Prodrug forms provide ease of manufacturing, good shelf life, and bioavailibility.
摘要:
The invention relates to compounds of formula (I), in which R1, R2, R3, R4, R5, R6, n and X are as defined in the specification, and to pharmaceutical compositions containing them. These compounds are excellent progestogens which are devoid of residual androgenic activity.
摘要:
Certain benzopyran antiestrogens are disclosed for treating estrogen sensitive diseases such as breast cancer. Prodrug forms provide ease of manufacturing, good shelf life, and bioavailibility, and preferred stereoisomers are shown to be more effective than racemic mixtures.
摘要:
Novel acridinium esters that are useful, either alone or when incorporated into liposomes, as chemiluminescent agents in binding assays (e.g., immunoassays and gene probe assays) with improved sensitivity are disclosed. In addition, the synthesis of these esters and their use in assays for detecting an analyte is described. In particular, assays for testosterone and the Rubella virus are disclosed.
摘要:
To provide a novel antitumor steroid compound which can be synthesized efficiently and stereoselectively by the technique of organic synthetic chemistry. A steroid derivative represented by general formula (I) or a salt thereof, wherein R represents C1-C13 alkyl; A represents hydroxyl or a group which can readily be hydrolyzed into a hydroxyl group; and X and Y represent in combination oxo or C2-C3 alkylenedioxy, or separately X represents hydroxyl, C1-C5 alkoxy or a group which can readily be hydrolyzed into a hydroxyl group, and Y represents hydrogen or C1-C5 alkoxy, provided Y represents hydrogen when X represents hydroxyl or a group which can readily be hydrolyzed into a hydroxyl group, while Y represents C1-C5 alkoxy when X represents C1-C5 alkoxy.
摘要:
A steroid with a 17-spiromethylene lactone group having formula I
wherein R₁ is O, (H,H), (H,OR), or NOR, R being selected from H, (1-6C) alkyl and (1-6C) acyl; R₂ is H, (1-6C) alkyl optionally substituted by a halogen, (2-6C) alkenyl optionally substituted by a halogen, (2-6C) alkynyl optionally substituted by a halogen, or halogen; R₂' is H; or R₂' together with R₂ is a (1-6C) alkylidene group or a (2-6C) alkenylidene group; or R₂' together with R₃ is a bond; R₃ is H if not together with R₂' a bond; R₄ is (1-6C) alkyl; one of R₅ and R₆ is hydrogen and the other is hydrogen or (1-6C) alkyl; X is (CH₂) n or (C n H 2n-2 ) wherein n is 2 or 3, which is optionally substituted with hydroxy, halogen, (1-6C) alkyl, (1-6C) acyl, (7-9C) phenylalkyl, the phenyl group of which may be substituted with (1-6C) alkyl, (1-6C) alkoxy, hydroxy or halogen; Y is O or (H,OH); and the dotted lines indicate optional bonds, at least one of bonds 4-5, 5-10, and 9-10 being a double bond. The steroids of the invention have progestational activity and can be used as contraceptives.
摘要:
19-Fluoro- and cyano- substituted 21-hydrox- yprogesterone derivatives and related compounds which are active as 19-hydroxylase inhibitors and useful as antihypertensive agents are described herein. The compounds are prepared using appropriate synthetic pathways which will vary according to the nature of the specific 19-substituted progesterone or related compound desired.
