摘要:
Selective IgE production inhibitors which contain substances inhibiting the production of IgE in the process of the differentiation of matured B cells into antibody-producing cells and the production of the antibody thereby while not or scarcely inhibiting the production of IgG, IgM and/or IgA to be produced simultaneously with IgE; compounds represented by general formula (I); a process for producing the same; and drugs containing the same. In said formula R to R represent each hydrogen, halogeno, lower alkyl, lower alkoxy, etc.; X represents O-, -CH2-, -NR - or -S(O)p-; and Y represents lower alkyl or lower alkenyl.
摘要:
There are described compounds of formula (I), wherein R1 is halo-C1-C6alkyl; halo-C2-C6alkenyl; or halo-C3-C6alkynyl; R2 is halogen, nitro, cyano, C1-C10alkyl, C2-C6alkenyl, C2-C6alkynyl, C3-C8cycloalkyl, C1-C6alkoxy, C3-C6alkenyloxy, halo-C1-C10alkyl, halo-C2-C6alkenyl, halo-C1-C6alkoxy, C3-C6alkynyloxy, C1-C4alkylthio, di(C1-C4-alkyl)amine in which the two alkyl groups are independent of one another; aryl, aryloxy, arylthio, or substituted aryl, aryloxy or arylthio; R3 is hydrogen or unsubstituted or substituted C1-C10alkyl; or benzyl in which the phenyl ring is unsubstituted or monosubstituted by a substituent selected from the group consisting of nitro, halogen, -CF3, -CN and C1-C4alkyl; m is 1, 3, 5, 7 or 9; n is 0, 1, 2, 3 or 4; and X is hydrogen, fluorine or methyl; in free form or in salt form, with the proviso that m may not be (1) when X and R3 are hydrogen, n is 0 and -O-R1 is 4-trifluoromethoxy; a process for the preparation of such compounds and the use of such compounds, pesticidal compositions in which the active ingredient is selected from those compounds, in free form or in an agrochemically suitable salt form, a method of preparing such compositions and the use of such compositions, plant propagation material treated with such compositions, and a method of controlling pests.
摘要:
A rubber composition comprising a natural and/or synthetic rubber, a filler and an acrylamide compound represented by the formula of X-NH CH=CH₂
wherein X is an aliphatic or alicyclic group, phenyl or phenoxyphenyl, in which said aliphatic or alicyclic group may contain halogen or oxygen in the group, said phenyl may be substituted once or twice by halogen, hydroxy, alkyl of 1 to 8 carbon atoms, alkoxy of 1 to 8 carbon atoms, nitro, cyano, carboxy or alkoxycarbonyl, and said phenoxyphenyl is represented by the formula of wherein Q¹ and Q² independently of one another are each hydrogen, alkyl of 1 to 8 carbon atoms, cyclohexyl, phenyl, halogen, hydroxy or amino. This rubber composition is increased in its loss factor, and is useful for tires and tread parts. The resulting tires prepared from the rubber composition are improved in their gripping performance.
