摘要:
The present invention provides a novel horticultural and agricultural fungicidal composition which contains as an effective component a 2H-chromene-2-spiro-3'-phthalide derivative and a method for killing fungus on plants.
摘要:
A wood preservative composition for control of wood decay by fungi, which comprises 2H-benzopyran-2-spiro-3'-phthalide or its derivatives such as 6-methyl-2H-benzopyran-2-spiro-3'-phthalide or benzo[f]-2H-benzopyran-2-spiro-3'-phthalide as an active ingredient. The active ingredient has extremely low mammalian toxicity, and exhibits an excellent wood-decay controlling effect.
摘要:
This invention relates to a novel prostacyclin represented by the formula: ##STR1## [wherein R.sup.1 represents --CO.sub.2 R.sup.5 group or --CONR.sup.6 R.sup.7 group; A is(i) --CH.dbd.CH--CH.sub.2 CH.sub.2 -- or(ii) --CH.sub.2 CH.sub.2 --O--CH.sub.2 --;B represents --C.tbd.C-- group; R.sup.2 represents an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, a phenyl group or a phenoxy group;R.sup.3 represents a hydrogen atom, a methyl group or a vinyl group; R.sup.4 represents a hydrogen atom, an acyl group, a tri(1 to 7 carbon atoms)hydrocarbyl-silyl group or a group forming an acetal bond with an oxygen atom of a hydroxy group; a double bond in the substituent represented by A is E or Z, or a mixture thereof; asymmetric center in the substituent represented by R.sup.2 is an R-configuration or S-configuration, or a mixture thereof];and uses in which they are employed as circulation ameliorating pharmaceuticals for blood flow ameliorating, antithrombus and the like, or antiulcer pharmaceuticals.
摘要:
Disclosed are a thiazole derivative represented by the following formula, a pharmaceutically acceptable salt thereof and leukotriene antagonist containing the same as the active ingredients: ##STR1## wherein R.sub.1 and R.sub.2 each independently represent a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a lower alkoxycarbonyl group or a substituted or unsubstituted phenyl group or cooperatively represent a tetramethylene group corresponding to a fused cyclohexane ring or a butadienylene group which is unsubstituted or substituted with a halogen atom, a lower alkoxy group, a lower alkoxycarbonyl group or an alkyl group having 1 to 3 carbon atoms corresponding to a fused benzene ring; R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each independently represent a hydrogen atom, a hydroxyl group, a lower alkoxy group, an alkyl group having 1 to 3 carbon atoms or a halogen atom; A represents a linking group having 2 to 4 chain members; B represents a linking group having 2 to 5 chain members; and Q represents a carboxyl group, a lower alkoxy group, a hydroxyl group, an alkoxycarbonyl group having 2 to 6 carbon atoms or a 5-tetrazolyl group.
