Abstract:
A (4-arylpiperazin-1-yl)piperidine derivative is provided to inhibit activities of beta-secretase, thereby treating and preventing neurodegenerative diseases such as Alzheimer diseases and Downs syndrome. A pharmaceutical composition comprises piperidine derivative wherein arylpiperazin is substituted represented by the formula 1 and pharmaceutically allowable salts thereof. In the formula 1, R1 and R2 are independently -O-CO-R4 or the formula 1a, wherein R4 represents C6-C12 aryl group in which C6-C10-aryl-C1-C4 alkyl group, C6-C12 aryl group, C1-C5 aryloxy or C6-C12 aryloxy group is substituted; and R3 is hydrogen, -CO-NH-(CH2)m-R5 or -CO-NH-C(R6)(R7)-(CH2)m-COO-R8. In the formula 1a, Z is hydrogen, halogen, C1-C4 liner or branched alkyl group or C1-C5 alkoxy group, wherein R5 is C6-C12 aryl group in which one or two C1-C4 linear or branched alkyl, C1-C5 alkoxy or halogen; m is an integer of 0~2; R6 and R7 are independently hydrogen, C1-C4 linear or branched alkyl group or benzyl group; and R8 is C1-C4 linear or branched alkyl group.

Abstract:
PURPOSE: A new oxazole derivative obtained by using amide as a starting material is provided which has a strong antibacterial effect on plant pathogenic bacteria with a small amount, for example Pyricularia oryzae Cavera, Rhizoctonia SolaniAG-1, Botrytis cinerea KCI, Phytophthora infestans or the like. CONSTITUTION: An amid compound(formula II) is refluxed in a solvent of dichloroacetone and ethanol to give chloromethyl oxazole(formula III). A chlorine atom of the chloromethyl oxazole is substituted to an iodine atom by use of sodium iodide and then reacted with 2-(2-hydroxyphenyl)-3-methoxy acrylic acid methylester(formula IV)(in case of A=C) or 2-methoxyimino-(2-hydroxyphenyl)-acetic acid methylester(formula IV)(in case of A=N) to produce an oxazole derivative(formula I).
