摘要:
An imidazoline derivative represented by general formula (1), wherein R1 represents a water- or fat-soluble substituent, in particular, carboxyl or carbomethoxy, or a pharmaceutically acceptable salt group thereof. A process for producing the same. A blood pressure retentive containing as the active ingredient the above imidazoline derivative or another imidazoline derivative wherein R1 in formula (1) represents hydrogen. The above imidazoline derivative is a novel substance, and both this compound and the imidazoline derivative wherein R1 represents hydrogen are useful as the blood pressure retentive for treating hypotensive shock by removing excessive NO which is the substantial ingredient of a vascular smooth muscle relaxant (EDRF).

The invention provides insecticidally active compounds of formula (I):
wherein X is nitrogen or carbon bearing a hydrogen atom; R¹ is a group of formula ―S(O) n -Y, wherein Y is an optionally substituted heterocyclic ring containing at least one nitrogen atom, the point of attachment of the group Y being at a ring nitrogen atom, and n is 0, 1 or 2; R² is a group of formula ―OSO₂R³ wherein R³ is selected from C₁₋₈ alkyl, C₁₋₄ alkyl substituted by an optionally substituted phenyl or heterocyclic ring, C₁₋₈ haloalkyl, C₂₋₆ alkenyl, C₂₋₄ alkenyl substituted by an optionally substituted phenyl or heterocyclic ring, C₂₋₄ alkynyl, C₂₋₄ alkynyl substituted by an optionally substituted phenyl or heterocyclic ring, optionally substituted aryl, and a group of formula ―N(R⁴)(R⁵) wherein R⁴ and R⁵ are independently selected from hydrogen and C₁₋₆ alkyl or wherein R⁴ and R⁵ together represent ―(CH₂) p ― wherein p is 2, 3, 4 or 5; and wherein the groups R² and R¹ occupy either a 1,3 configuration relative to each other on the ring when X is carbon bearing a hydrogen, or a 2,4 or 2,6 configuration relative to the group X when X is nitrogen. The invention also provides compositions comprising the compounds of formula (I) and methods of their use in combating insect pests, and novel intermediates and chemical processes for their preparation.
摘要:
A method of synthesizing organic molecules is provided, wherein the method comprises providing an electrophilic educt, providing an ionic liquid comprising a carbanion, and synthesizing the organic molecules by mixing the electrophilic educt and the ionic liquid.
摘要:
This invention pertains to certain active carbamic acid compounds which inhibit HDAC activity and which have the following formula: wherein: A is an aryl group; Q is an aryl leader group having a backbone of at least 2 carbon atoms; J is an amide linkage selected from: -NR C(=O)- and -C(=O)NR -; R is an amido substituent; and, Q is an acid leader group; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, and prodrugs thereof, for use in the treatment of parasitic infections, such as malaria.
