Abstract: An object is to provide a novel benzoxazine compound that has high heat resistance and can cure under low temperature conditions, a resin raw material composition containing the benzoxazine compound, a curable resin composition, and a cured product thereof. As a solution, a benzoxazine compound represented by general formula (1) is provided: wherein R1 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and R2 represents an alkylene group having 1 to 6 carbon atoms.

Abstract: A method for producing a benzoxazine compound represented by general formula (3), includes performing a reaction by mixing a mixture containing a bisphenol compound represented by general formula (1) and a formaldehyde with an amine compound represented by general formula (2):

Abstract: A benzoxazine compound is represented by general formula (1): wherein R1 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, R2 represents a divalent group having 1 to 10 carbon atoms, and X represents a single bond, an oxygen atom, a sulfur atom, a sulfonyl group, a carbonyl group, or a divalent group represented by general formula (1a) or general formula (1b), and wherein R3 and R4 each independently represent hydrogen, an alkyl group having 1 to 10 carbon atoms, an alkyl halide group having 1 to 10 carbon atoms, or an aryl group having 6 to 12 carbon atoms, R3 and R4 are optionally bonded to each other to together form a cycloalkylidene group having 5 to 20 carbon atoms, An and Are each independently represent an aryl group having 6 to 12 carbon atoms, and * represents a bonding position.

Abstract: Phytol contained in watermelon sprouts is known to have a cancer cell growth inhibiting effect. However, there is a problem that an amount of phytol to be taken for exhibiting cancer cell growth inhabition is large. A cancer cell growth inhibiting composition comprising at least one of compounds having a structure represented by Formula (1), Formula (2), Formula (6), Formula (7) or Formula (8), or a pharmaceutically acceptable salt thereof as main components has a higher cancer cell growth inhibiting effect than phytol.
