Abstract:
A 2-cyanoacrylate composition comprising a cyclic phenol sulfide derivative. The composition has a high curing rate and is excellent in moist-heat resistance, surface curability and clearance curability.
Abstract:
The present invention is intended to provide an agent for treating male infertility which is highly effective to male infertility, and having few side effects. To achieve the object, an agent for treating male infertility comprising δ-amino levulinic acid shown by general formula (1), its derivative or salt thereof: R2R1NCH2COCH2CH2COR3 (1) [wherein R1 and R2 independently represent a hydrogen atom, alkyl group, acyl group, alkoxycarbonyl group, aryl group, or aralkyl group; R3 represents a hydroxy group, alkoxy group, acyloxy group, alkoxycarbonyloxy group, aryloxy group, aralkyloxy group or amino group] can be used.
Abstract:
To provide a polyphenol-content-increasing agent which increases the content of polyphenol in a plant. A polyphenol-content-increasing agent for plant, containing, as an active ingredient, a 5-aminolevulinic acid or a derivative thereof represented by the following formula (1):(Chem 1) R2R1NCH2COCH2CH2COR3 (1) wherein R1 and R2 each independently represents a hydrogen atom, an alkyl group, an acyl group, an alkoxycarbonyl group, an aryl group, or an aralkyl group; R3 represents a hydroxyl group, an alkoxy group which may have a substituent, an acyloxy group, an alkoxycarbonyloxy group, an aryloxy group, an aralkyloxy group, or an amino group, or a salt thereof.
Abstract:
