摘要:
Compounds having bactericidal activities and represented by general formula (I) and salts and hydrates thereof wherein R1 represents an optionally substituted aryl, an optionally substituted alkyl or the like; R2 represents an optionally substituted alkyl, an optionally substituted alkenyl, an optionally substituted alkynyl, an optionally substituted aryl, an optionally substituted heterocyclic group or the like; R3 represents an optionally substituted alkyl, an optionally substituted alkenyl, an optionally substituted alkynyl, an optionally substituted arylsulfonyl, an optionally substituted heterocyclic group or the like; R?4 and R5¿, which may be the same or different, represent each a hydrogen atom, an optionally substituted alkyl, or an optionally substituted alkoxy, or R?4 and R5¿ may form together with the adjacent nitrogen atom an optionally substituted monocycle or polycycle; X and Y, which may be the same or different, represents each an oxygen atom or NR6 (wherein R6 represents a hydrogen atom, an optionally substituted alkyl, an optionally substituted aryl, an optionally substituted alkanoyl, or an optionally substituted aroyl); Z represents an oxygen atom or a sulfur atom; and a wavy line (∩) represents the configuration of an E isomer, a Z isomer, or a mixture thereof.
摘要:
Nitrogenous heterocyclic derivatives represented by the general formula (I) which each bind specifically to NR1/NR2B receptor and are useful as NR2B receptor antagonists (particularly analgesic for cancer pain or neuroprotectant); pharmaceutically acceptable salts thereof; or solvates of both: (I) wherein Z is N or CR 1 ; A 1 is a (substituted) nitrogenous aromatic mono- or fused-cyclic group having -NH- in the ring; A 2 is a (substituted) aromatic carbocyclic group or a (substituted) aromatic heterocyclic group; R 1 and R 2 are each independently hydrogen, hydroxy, or the like; R a , R b , R c and R d are each independently hydrogen or lower alkyl; w is 2 or 3; t is 1 or 2; X is -CONR 5 (CR 3 R 4 )n-, -NR 5 CO(CR 3 R 4 )n-, -NR 5 COCO(CR 3 R 4 )n-, -(CR 3 R 4 )mCONR 5 -, or the like; m is 1 to 4; n is 0 to 4; R 3 and R 4 are each independently hydrogen, halogeno, hydroxyl, or the like; and R 5 's are each independently hydrogen or lower alkyl.
摘要:

Compounds represented by the following structural formula, pharmaceutically acceptable salts or hydrates thereof and medicinal compositions containing the same: (I) Each of these compounds is useful alone as an anti-helicobacterial agent.
摘要:
Compounds of general formula (I) are excellent bacteriocides exhibiting wide bacteriocidal spectra, wherein R1 is a heterocyclic group, CHO or CH¿2?OR?6; R2¿ is alkyl; R3 is hydrogen, alkyl, alkoxy, halogeno, nitro, cyano or haloalkyl; R4 is hydrogen, alkyl, cycloalkyl, alkoxyalkyl, alkoxycarbonyl, cyano, haloalkyl, aryl or a heterocyclic group; R5 is hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, alkanoyl, aroyl, alkoxycarbonyl, aryl or a heterocyclic group; A is (1) -CH¿2?ON=C(R?7¿)-, (2) -CH¿2?N(R?8)-N=C(R7¿), (3) -CH=NOC(R9)(R10)- or (4) -CH=NN=C(R7)-; B is oxygen or NR11; each wavy line refers to the configuration of an E- or Z-isomer or a mixture of both.
摘要:
A process for producing an alpha -alkoxyiminophenylacetonitrile represented by general formula [III], (wherein R , R , R and Y are each as defined in the specification) by reacting an alkali metal salt of an alpha -hydroxyiminophenylacetonitrile, represented by general formula [I], (wherein R , R , Y and A are each as defined in the specification) with a dialkyl sulfate represented by the general formula [II]: (R )2SO4, (wherein R is as defined in the specification) in the presence of a phase transfer catalyst in a solvent mixture composed of a hydrocarbon solvent and water. It is possible by using the above catalyst and solvent mixture to inhibit the formation of a nitrone derivative as a by-product to thereby produce a highly pure alkoxyimino compound in a high yield.
