Esters, Retroesters, and a Retroamide of Palmitic Acid: Pool for the First Selective Inhibitors of N-Palmitoylethanolamine- Selective Acid Amidase
摘要:
Cyclohexyl hexadecanoate, hexadecyl propionate, and N-(3-hydroxypropionyl)pentadecanamide, respectively ester, retroester, and retroamide derivatives of N-palmitoylethanolamine, represent the first selective inhibitors of "N-palmitoylethanolamine hydrolase" described so far. These compounds are devoid of affinity for CB, and CB2 receptors and characterized by high percentages of inhibition of N-palmitoylethanolamine-selective acid amidase (84.0, 70.5, and 76.7% inhibition at 100 muM, respectively) with much lower inhibitory effect on either fatty acid amide hydrolase or the uptake of anandamide.

Tosylates and mesylates were directly converted into the corresponding nitroalkanes, by their treatment with tetrabutylammonium nitrite (TBAN) under mild conditions.

The 1-octyl, 1-pentadecyl, 1-hexadecyl, 1-heptadecyl, and 1-octadecyl diesters of (6-deoxy-alpha-D-gluco-heptopyranosyluronic acid) 6-deoxy-alpha-D-gluco-heptopyranosiduronic acid, a new homolog of trehalosuronic acid, were prepared by two procedures. One procedure involved conversion of the peracetylated acid into its dichloride, reaction of the latter with the alkanols, and acid-catalyzed deacetylation of the products, whereas the other consisted of reaction of alkyl mesylates with the potassium salt of the unprotected acid.
