BIOISPIRED PROTEASOME ACTIVATORS WITH ANTIAGEING ACTIVITY
-
Page/Page column 7; 19, (2019/10/01)
The present invention relates to novel bio-inspired hybrid compounds of formula I which act as proteasome activators and exhibit anti-ageing activity, as well as methods for their synthesis. These hybrid compounds combine the structural features of hydroxytyrosol and the natural antioxidant vitamin E or its bioisosteres in one molecular scaffold. The compounds of formula I, which include structural proteasome activators (activation by stereochemical interaction), can be used in the production of anti-ageing products, such as cosmetic preparations. Additionally, they can be used in conditions and diseases where the proteasome is down-regulated, as well as proteasome-activation control compounds.

A simple and original inverse electron demand hetero-Diels-Alder reaction has been successfully applied to the synthesis of (2-ambo,4′R,8′R)- α/β/γ/δ-4-thiatocopherol. Commercially available methyl hydroquinones and. (2E,7R,11R)-(+)-phytol were exploited for the preparation of the ortho-thioquinones, acting as electron-poor dienes, and of the proper 1,3-diene used as dienophile, respectively. The benzoxathiine cycloadducts, with the required tocopherol-like skeleton, were obtained with complete control, of regio and chemoselectivity. The antioxidant activity of 4-thiatocopherols was measured and rationalized in comparison with that of the corresponding natural components of Vitamin E.

The inhibitory effects of newly synthesized 4-alkoxyaryl β-D- glucopyranosides on histamine release from rat peritoneal mast cells induced by concanavalin A were examined. A plot of hydrophobicity (k') against inhibitory activity of the compounds showed a distinct maximum, and 4- decyloxy-2,3,6-trimethylphenyl β-D-glucopyranoside was the most potent inhibitor among the tested compounds.
