M. Macchia et al., SYNTHESIS AND ALDOSE REDUCTASE INHIBITORY ACTIVITY OF SOME N-(AROYL)-N-(ARYLALKYLOXY)-GLYCINES AND N-(AROYL)-N-(ARYLALKYLOXY)-BETA-ALANINES, Il Farmaco, 51(4), 1996, pp. 255-260
Some N-(aroyl)-N-(phenylethyloxy)glycines (C) and N-(aroyl)-N-(arylmet
hyloxy)beta-alanines (D) were synthesised and tested as aldose reducta
se inhibitors (ARIs). Compounds C and D differ from the previously rep
orted ARIs of type A in the presence of a further CH2 spacer between t
he aryl moiety and the oxyamidic oxygen and between the oxyamidic nitr
ogen and the carboxyl group. Compounds C revealed a certain loss of in
hibitory activity with respect to the corresponding type A derivatives
. Compounds D were found to be devoid of any appreciable inhibitory ac
tivity.
