Design, Synthesis, and Biological Effect of (1-Oxo-1,2,3,4-tetrahydro-β-carbolin-9-yl)acetic Acids as Inhibitor of Aldose Reductase 2
摘要:
Design and synthesis of (1-oxo- 1,2,3,4-tetrahydro-beta-carbolin-9-yl)acetic acids (4a-e) have been described, The acids (4a-e) synthesized here showed good to moderate inhibitory effects (IC50 = 21.7 similar to 45.3 mu M) for the aldose reductase 2 (ALR2).

A fused tricyclic compound having aldose reductase inhibitory activity and shown by the following formula,
wherein R
1
represents 1 to 3 atoms or substituents selected from a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl, cycloalkyl, alkylene, or alkoxy group, and a protected or unprotected hydroxyl or carboxyl group, R
2
represents a protected or unprotected carboxyl group, R
3
represents 1 or 2 atoms or substituents selected from a hydrogen atom, a halogen atom, an oxo group, a substituted or unsubstituted alkyl or alkoxy group, and a protected or unprotected carboxyl group, A represents an alkylene group, and B represents an oxygen atom, a sulfur atom, or a group shown by the following formula,
wherein R
4
represents an alkyl or aryl group substituted by an aryl, cycloalkyl, or heterocyclic group, and X represents an oxygen atom or a sulfur atom, provided that, when B represents a group shown by the following formula:
wherein R
4
represents an alkyl or aryl group substituted with an aryl, cycloalkyl, or heterocyclic group, X represents a sulfur atom.
