摘要:
Alkyl ether derivatives represented by the general formula [1] or salts thereof exhibit activities of protecting the nerve, accelerating nerve regeneration, and potentiating axon growth, and are useful as remedies for central and peripheral nerve diseases: [1] wherein R1 and R2 are each hydrogen, halogeno, alkyl, aryl, aralkyl, alkoxy, aryloxy, alkylthio, arylthio, alkenyl, alkenyloxy, amino, alkylsulfonyl, arylsulfonyl, carbamoyl, a heterocyclic group, hydroxyl, carboxyl, nitro, oxo, or the like; R3 is alkylamino, amino, hydroxyl, or the like; A is a five- or six-membered aromatic heterocycle or a benzene ring; m and n are each an integer of 1 to 6; and p is an integer of 1 to 3.
摘要:
A process for the production of sulfonic ester derivatives of the general formula (4) or (5) by reacting an amino alcohol of the general formula (1) or (2) with an organic sulfonyl halide of the general formula (3) in a mixed solvent of an aprotic organic solvent and water in the presence of a non-water-prohibitive inorganic base. This process is reduced in the load on the environment and can be carried out simply, safely and economically: (1) (2) (3)(4) (5) wherein n is an integer of 0 to 5; A is optionally substituted phenyl; R is methanesulfonyl, ethanesulfonyl, p-toluenesulfonyl, or p-nitrobenzenesulfonyl; and X is chloro, bromo, or iodo.

摘要:
The present invention relates to inhibitors of post-proline cleaving enzymes, such as inhibitors of dipeptidyl peptidase IV, as well as pharmaceutical compositions thereof, and methods for using such inhibitors. In particular, the inhibitors of the present invention are improved over those in the prior art by selection of particular classes of sidechains in the P1 and/or P2 position of the inhibitor. The compounds of the present invention can have a better therapeutic index, owing in part to reduced toxicity and/or improved specificity for the targeted protease.; The present invention relates to inhibitors of post-proline cleaving enzymes, such as inhibitors of dipeptidyl peptidase IV, as well as pharmaceutical compositions thereof, and methods for using such inhibitors.
