Inhibitory or blocking agents of molecular generating and/or inducing functions

A method for inhibiting or blocking molecular generating and/or inducing functions of a substance comprising contacting said substance with an inhibiting or blocking effecting amount of a compound represented by formula 2:

• (wherein
• (i) R1, R2, R3, R4, R5 and R6 represent independently hydrogen atom;
• halogen atom;
• C1-C6 alkyl group;
• amidino group;
• C3-C8 cycloalkyl group;
• C1-C6 alkoxy C1-C6 alkyl group;
• aryl group;
• allyl group;
• aralkyl group in which one or more C1-C6 alkyl groups are bound to an aromatic ring selected from the group consisting of benzene, naphthalene and anthracene ring;
• C1-C6 alkylene group;
• benzoyl group;
• cinnamyl group;
• cinnamoyl group or furoyl group;
• (ii) one or more of R1, R2, R3 and R4, and/or one or more of R5 and R6 may be substituted or non-substituted cyclopentyl group;
• substituted or non-substituted cyclohexyl group;
• or substituted or non-substituted naphthyl group;
• (iii) R5 and R6 may form a ring by binding with another condensation polycyclic hydrocarbon compound or heterocyclic compound;
• (iv) one or more of R3, R4, R5 and R6 may be substituted by one or more of substituents selected from the group consisting of halogen atom, cyano group, protected or non-protected carboxyl group, protected or non-protected hydroxyl group, protected or non-protected amino group, C1-C6 alkyl group, C1-C6 alkoxy group, C1-C7 alkoxy carbonyl group, aryl group, C3-C6 cycloalkyl group, C1-C6 acylamino group, C1-C6 acyloxy group, C2-C6 alkenyl group, C1-C6 trihalogenoalkyl group, C1-C6 alkylamino group, and C1-C6 dialkylamino group;
• (v) R2 and/or R5 may be substituted by one or more substituents selected from the group consisting of halogen atom, C1-C6 alkyl group, protected or non-protected carboxyl group, protected or non-protected hydroxyl group, protected or non-protected amino group, protected or non-protected C1-C6 alkylamino group, protected or non-protected C1-C6 aminoalkyl group, protected or non-protected C1-C6 alkylamino C1-C6 alkyl group, protected or non-protected hydroxyalkyl group, and C3-C6 cycloalkylamino group;
• (vi) when one or more of R3, R4, R5 and R6 are alkyl groups, terminal end(s) of the alkyl group(s) may be substituted by C3-C8 cycloalkyl group).
