Compounds of Formula (I)a or (I)b: ##STR00001##
including certain quinone derivatives, and the corresponding pharmaceutical compositions, which may serve to modulate ferroptosis in a subject. Also disclosed herein are the preparations of these compounds and pharmaceutical compositions and their potential uses in the manufacture of a medicament in reducing reactive oxygen species (ROS) in a cell and for preventing, treating, ameliorating certain related disorder or a disease.

Methods of treating aging related skin changes and of increasing skin thickness with topical administration of N-acyldipeptide derivatives are described. Compositions comprising N-acyldipeptide derivatives, are therapeutically effective for increasing skin thickness, and for treating extrinsic and intrinsic aging and aging related skin changes, such as fine lines, wrinkles, photoaging, hyperpigmentation, laxity, age spots, lentigines, mottled skin, and cellulite.
