By tethering of a polar hydrophilic group to the P1 or P1' substituent of a Phe-based hydroxyethylene isostere, the antiviral potency of a series of HIV protease inhibitors was improved. The optimum enhancement of anti-HIV activity was observed with the 4-morpholinylethoxy substituent. The substituent effect is consistent with a model derived from inhibitor docked in the crystal structure of the native enzyme. An X-ray crystal structure of the inhibited enzyme determined to 2.25 A verifies the modeling predictions.

Chiral N-protected β-amino alcohols are easily obtained by NaBH4 reduction of mixed anhydrides of N-protected α-amino acids in an organic/aqueous medium. The alcohols obtained from side chain or main chain reduction of N-protected aspartic acid are converted in good yields into lactones.

Autotaxin (ATX) is an attractive pharmacological target due to its lysophospholipase D activity which leads to the production of lysophosphatidic acid (LPA). Blockage of ATX produced LPA by small molecules could be a potential anticancer chemotherapy. In our previous study, we have identified the two β-hydroxy phosphonate analogs of LPA (compounds f17 and f18) as ATX inhibitors. With this work, we investigated α- and β-substituted phosphonate analogs of LPA and evaluated them for ATX inhibitory activity. The stereochemistry of β-hydroxy phosphonates was also studied.

It is generally accepted that the conformation of the N-terminal part of neurohypophyseal hormones analogues is important for their pharmacological activity. In this work, we decided to investigate how the substitution of positions 2 and 3 with the ethyle
Direct synthesis of N-protected β-amino dimethylhydroxamates: Application to the solid-phase synthesis of a peptide incorporating a new amide bond surrogate ψ[CH2CH2NH]

A rapid and efficient one-step synthesis of N-protected β-amino dimethylhydroxamates starting from diazo ketones is reported. A Fmoc- protected β-amino aldehyde obtained by reduction of its corresponding dimethylhydroxamate was incorporated during solid p

A series of novel aminodiol inhibitors of HIV protease based on the lead compound 1 with structural modifications at P1′ were synthesized in order to reduce the cytotoxicity of 1. We have observed a high degree of correlation between the lipophilicity and the cytotoxicity of this series of inhibitors. It was found that appropriate substitution at the para position of the P1′ phenyl group of 1 resulted in the identification of equipotent (both against the enzyme and in cell culture) compounds (101, 10m, 10n, and 15c) which possess significantly decreased cytotoxicity.
SYNTHESIS OF FRAGMENTS OF THE VP1 PROTEIN OF TYPE A22 FOOT-AND-MOUTH DISEASE VIRUS. SYNTHESIS OF FRAGMENTS 134-139, 134-145, 140-145, 150-155, AND 150-159
