摘要:
Compounds I ##STR1## with R equal to hydrogen or (C.sub.1 -C.sub.4)-alkyl,X equal to (CH.sub.2).sub.n with n=1-4, unsubstituted or substituted, andAr is equal to an aromatic or heteroaromatic system, optionally substituted,and their pharmaceutically tolerated salts are valuable pharmaceuticals for the treatment of cerebral edema or diarrhea.
摘要:
The invention relates to cycloalkyl substituted 4-aminophenyl derivatives of formula (I) ##STR1## wherein R is C.sub.1 -C.sub.4 alkyl:n is an integer of 1 to 5; and either(a) A is ##STR2## and B is --O--, --NH-- or --CH.sub.2 --; or (b) A is --CH.sub.2 -- and B is --O--, --NH--, --CH.sub.2 -- or ##STR3## or (c) A is --O-- and B is ##STR4## or --CH.sub.2 --; or (d) A is --NH-- and B is ##STR5## or --CH.sub.2 -- and their pharmaceutically acceptable salts.The scope of the invention includes also a process for preparing the said compounds of formula (I) and pharmaceutical compositions containing same.The compounds of the invention show aromatase inhibiting activity and can be useful, e.g., in treating hormone-dependent tumors and prostatic hypertrophy or hyperplasia.
摘要:
[1,1'-Biphenyl]-3-ylmethyl pyrethroid esters, as well as processes, uses, and intermediates thereto, are disclosed. The [1,1'-biphenyl]-3-ylmethyl pyrethroid esters control a broad spectrum of insects as well as acarids.
摘要:
2,2'-Bridged[1,1'-biphenyl]-3-ylmethyl carboxylates and insecticidal compositions containing these esters are useful for the control of a broad range of insects and acarids. Certain 3-(2,2-dihaloethenyl)-2,2-dimethylcyclopropyl and 3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropyl esters are particularly effective against acarids.

2,2'-Bridged[1,1'-biphenyl]-3-ylmethyl cyclopropanecarboxylates and insecticidal compositions containing these esters are useful for the control of a broad range of insects and acarids.
摘要:
A regiospecific synthesis for anthracyclinones asymmetric is disclosed. The synthesis is based upon a regiospecific bromination of the C-7 position of the .alpha.-tetralone which after transposing the keto group to the .beta.-position and reaction with an organo-lithium compound is condensed with a phthalate ester.
摘要:
A method of producing alkandiol-diaminobenzoates which includes esterifying nitro-benzoic acid and certain diols in a melt and then dissolving the intermediate in a solvent sparingly soluble in water such as an aromatic hydrocarbon, an ether or an ester and reducing with hydrogen gas.
摘要:
Aminosulfonyl-substituted aryloxyalkyl diketones, useful as antiviral agents, are prepared by reacting a haloalkyl diketone with an alkali metal salt of a hydroxybenzenesulfonamide.
摘要:
There are disclosed herein derivatives of bisfunctionalized compounds, wherein said compounds have been formed by the introduction of a nitro group and a hydroxyl group in the form of an ester into a conjugated diene molecule by treatment of said conjugated dienes with nitric acid in the presence of a carboxylic acid anhydride. The novel compounds produced by this process are useful as bactericides, fungicides and valuable organic synthesis intermediates.
