Abstract:
The spiro compounds of the present invention represented by the following general formula: wherein A, R 2 , R 3 , R 4 , R 5 , R 6 and n are as defined in the specification, exhibit an AP-1 activity inhibitory action and, based on the AP-1 inhibitory action, suppresses the expression of a wide variety of genes and are useful as an agent for treating and preventing autoimmune diseases with lessened side reactions.
Abstract:
A benzophenone derivative represented by the following formula: wherein
R 1 represents, for example, an optionally substituted heterocyclic group, or a substituted phenyl group; Z represents, for example, an alkylene group; R 2 represents, for example, a carboxyl group optionally protected with alkyl; R 3 represents, for example, an optionally protected hydroxyl group; R 4 represents, for example, an optionally substituted cycloalkyloxy group; and R 5 represents, for example, a hydrogen atom, or a salt thereof has anti-arthritic activity, inhibits bone destruction caused by arthritis, and provides high safety and excellent pharmacokinetics and thus is useful as therapeutic agent for arthritis. These compounds have inhibitory effect on AP-1 activity and are useful as preventive or therapeutic agent for diseases in which excessive expression of AP-1 is involved.
Abstract:
A compound comprising the atom corresponding to N 3 and the two or more atoms selected from N 1 , N 2 , N 4 and N 5 , said atoms constitute the pharmacophore represented by the following formula: wherein N 1 represents an atom to which a donative hydrogen atom in a hydrogen-bond donating group is bonded or a hydrogen-bond accepting atom in a hydrogen-bond accepting group; N 3 represents a hydrogen-bond accepting atom in a hydrogen-bond accepting group; and N 2 , N 4 and N 5 independently represents an arbitrary carbon atom constituting a hydrophobic group and defined by the interatomic distances between N 1 , N 2 , N 3 , N 4 and N 5 ; and, in the optimized three-dimensional structure thereof, the distances between the atom corresponding to N 3 and the two or more atoms selected from N 1 , N 2 , N 4 and N 5 , in the optimized steric structure thereof, are the interatomic distances in a pharmacophore; or a salt thereof; inhibits the activity of transcription factor AP-1 and is useful as an agent for preventing and treating the diseases into which overexpression of AP-1 participates and as an AP-1 inhibitor.
