The potential clinical utility of sodium butyrate, a natural compound known to inhibit tumor-cell growth, is hampered by the difficulty of achieving effective in-vivo concentrations. The short half-life (about 5 minutes) of sodium butyrate results in rapid metabolism and excretion.

The syntheses of four analogues of N4-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-L-asparagine are described. Activated carboxylic acids were reacted with 2-acetamido-2-deoxy-beta-D-glucopyranosylamine. n-Butyric anhydride gave N-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-n-butyramide. 3-Chloropropionic anhydride was synthesized from 3-chloropropionic acid and gave N-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-3-chloropropionamide. Equilibration of the latter with ammonium bicarbonate gave N1-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-3-aminopropionamide. Succinimidyl

Poly(2-methyl-2-oxazoline) (PMOZ), poly(2-propyl-2-oxazoline) (PnPOZ) and poly(2-isopropyl-2-oxazoline) (PiPOZ) were synthesized by hydrolysis of 50 kDa poly(2-ethyl-2-oxazoline) (PEOZ) and subsequent reaction of the resulting poly(ethylene imine) with acetic, butyric and isobutyric anhydrides, respectively. These polymers were characterized by proton nuclear magnetic resonance, FTIR

Dibutyrylchitin (DBC), a lipophilic chitin diester, has been synthesized from chitin and butyric anhydride with methanesulfonic acid as catalyst. Exhaustive esterification of free alcoholic groups of chitin was assessed by FT-IR and (1)H-NMR spectroscopy. High degree of alkyl substitution allowed
