SCYLLO-INOSITOL DERIVATIVES AND THEIR USE IN THE TREATMENT OF DISEASES CHARACTERISED BY ABNORMAL PROTEIN FOLDING OR AGGREGATION OR AMYLOID FORMATION, DEPOSITION, ACCUMULATION OR PERSISTENCE

摘要

Scyllo-Inositol derivatives represented by structural formula II are described, wherein at least one and not more than five of R¹, R², R³, R⁴, R⁵ and R⁶ is hydroxyl and the other of R¹, R², R³, R⁴, R⁵ and R⁶ are independently alkyl, alkenyl, alkynyl, alkylene, alkenylene, alkoxy, alkenyloxy, cycloalkyl, cycloalkenyl, cycloalkoxy, aryl, aryloxy, arylalkoxy, aroyl, heteroaryl, heterocyclic, acyl, acyloxy, sulfoxide, sulfate, sulfonyl, sulfenyl, sulfonate, sulfinyl, ammo, lmmo, azido, thiol, thioalkyl, thioaryl, mtro, cyano, halo, seleno, silyl, silyloxy, silylthio, carboxyl, carbonyl, carbamoyl or carbamide, or pharmaceutically acceptable salts thereof. Said derivatives and compositions comprising the same are useful in the prevention and/or treatment of diseases characterized by abnormal protein folding or aggregation or amyloid formation, deposition, accumulation or persistence.
