iminocyclitol-based smallmoleculelibraries against a bacterial TGase is described. An iminocyclitol was conjugated with a pyrophosphate mimic using either a 1,3-dipolar cycloaddition or reductive amination reaction, which was then condensed with a variety of lipophilic carboxylic acids in an amide bond coupling to generate a desired molecularlibrary. With assistance of microtiter plate-based combinatorial chemistry

We synthesized and evaluated new zwitterionic inhibitors against glycoside hydrolase-like phosphorylaseStreptomyces coelicolor(Sco) GlgEI-V279S which plays a role in α-glucan biosynthesis.
γ-Amino-β-hydroxyphosphonates, useful intermediates for the synthesis of phosphonic acid analogues of carnitine, were prepared as their protected derivatives in an enantioselective manner from β,γ-unsaturated phosphonates through asymmetric dihydroxylation and subsequent regioselective amination via the cyclic sulfates.
Phosphonicacidanalogues of acylcarnitine were prepared in an optically active form expecting CPT I inhibitory activities. The synthetic methodology was based on catalytic asymmetric dihydroxylation of β,γ-unsaturated phosphonates and subsequent regioselective amination via the cyclic sulfates.

Phosphonate substituted compounds with HIV protease inhibitory properties having use as therapeutics and for other industrial purposes are disclosed. The compositions inhibit 5 HIV protease activity and/or are useful therapeutically for the treatment of AIDS and other antiviral infections, as well as in assays for the detection of HIV protease.
