Aspirin inhibits the formation of pentosidine, a cross-linking advanced glycation end product, in collagen

Aspirin showed an inhibitory effect on the formation of pentosidine, a cross-linking advanced glycation endproduct, in collagen incubated with glucose in vitro. IC50 was evaluated at 10 mmol/l. Aspirin might act by metallic ion chelating (as did EDTA and DTPA) and by oxygen radical scavenging. Since aspirin was reported to inhibit retinopathy in diabetic dogs, it could act partly by inhibiting advanced glycation endproduct accumulation in long-lived proteins like collagens.
