    Preparation of sulfonamides from N-silylamines
    摘要:
    Sulfonamides have been prepared in high yields by the reactions of N-silylamines with sulfonyl chlorides and fluorides. In a competition experiment, the sulfonyl chlorides were found to be far more reactive than sulfonyl fluorides. The chemistry may be used to prepare aliphatic, aromatic, tertiary, secondary, and primary sulfonamides. It may also be done in the absence of solvent and the byproduct trimethylsilyl chloride recovered in good yield. Primary sulfonamides were synthesized from the sulfonyl chloride with aminotriphenyl silane (Ph3SiNH2), a conversion demonstrated with the synthesis of the carbonic anhydrase inhibitor, acetazolamide.

    For ligation to proteins the hexadienyl group was attached to avidin and streptavidin noncovalently by means of complex formation with a biotinylated peptide or by covalent attachment of a hexadienyl ester-containing label to lysine side chains incorporated into the proteins. Site-specific attachment of the hexadienyl unit into a Rab protein was achieved by means of expressed protein ligation followed

    either a PCU or adamantane amine moiety conjugated to different aromatic functionalities through various tethered linkers were selected based on their channel blocking abilities and evaluated as potential chemosensitizers. Compounds 2, 4, 5 and 10 showed significant voltage-gated calcium channel (VGCC) blocking ability (IC50 = 0.27–35 μM) and were able to alter the CQ IC50 in differing degrees (45–81%)

To gain insight into the structure-activity relationships of NOD2 antagonists, a series of novel analogs was designed and synthesized, and then screened for antagonist activity versus NOD2, and counter-screened versus NOD1.

    Abstract In this study, we report a series of newly synthesised sulphonamides of aziridine-2-carboxylic acid (Az-COOH) ester and amide analogues as potent protein disulphide isomerase (PDI, EC 5.3.4.1) inhibitors. The inhibitory activity on PDI was determined against recombinant human PDIA1 and PDIA3 proteins using an insulin reduction assay. These compounds in low micromolar to low nanomolar concentrations
