Abstract:
A novel compound is provided to show excellent activity on PDE-4 enzymes and high selectivity on other PDE enzymes, thereby being used as a therapeutic agent of inflammation related diseases, arthritis, atopic dermatitis, leukemia, various cancers and degenerative brain diseases with little side effects. A 1-[1-(3,4-dialkoxyphenyl)-alkyl]-1H-pyrazole compound is represented by a formula(1) and is prepared by reacting a halo-benzyl compound represented by a formula(2) with a pyrazole compound represented by a formula(3). In the formula(1), each R1 and R2 is independently H, linear or branched saturated or unsaturated C1-7 alkyl which may be substituted or unsubstituted by halogen, C3-7 cycloalkyl, (C3-7)cycloalkyl(C1-7)alkyl, aryl or heteroaryl, ar(C1-5)alkyl, or ar(C1-5)alkoxy, or the R1 and R2 may be linked to each other by C1-3 alkylene; each R3, R4 and R5 is independently H, phenyl, pyridinyl, N-oxypyridinyl, linear or branched saturated and unsaturated C1-7 alkyl, C3-7 cycloalkyl, (C3-10)cycloalkyl(C1-7)alkyl, halogen, cyano, nitro, amino, mono- or di(C1-7)alkylamino, mono or di(C1-7)alkylaminocarbonyl, C3-7 cycloalkylamino, 3 to 7-membered saturated or unsaturated hetero-ring including O, N or S, guanidinyl, ureido, benzyl, benzyloxy, formyl, C1-7 alkanoyl, C1-7 alkoxy, (C1-7)alkoxy(C1-7)alkyl, hydroxy(C1-7)alkyl, carboxyl, or (C1-7)alkoxycarbonyl; R6 is linear or branched saturated and unsaturated C1-7 alkyl, C3-7 cycloalkyl, (C3-10)cycloalkyl(C1-7)alkyl, phenyl, phenoxy, benzyl, benzyloxy, C1-7 alkoxy, or (C1-7)alkoxy(C1-7)alkyl. A pharmaceutical composition for treating or preventing diseases related to airway inflammation, arthritis, atopic dermatitis, leukemia, cancer or degenerative brain diseases comprises the 1-[1-(3,4-dialkoxyphenyl)-alkyl]-1H-pyrazole derivative as an effective ingredient.
