    摘要: This invention relates to matrix metalloproteinase (MMP) inhibiting compounds of the formula: ##STR1## where R.sup.1 is C.sub.1 -C.sub.12 alkyl, straight or branched and optionally substituted by halogen, hydroxy, C.sub.1 -C.sub.6 alkoxy, amino, carboxyl, C.sub.1 -C.sub.6 alkoxycarbonyl, carboxamido, nitrile, mono- or di-(C.sub.1 -C.sub.6)alkylamino, thio, C.sub.1 -C.sub.6 alkylthio, aryl, --Oaryl or --OCH.sub.2 aryl where aryl is optionally substituted with C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, carboxy, halogen, cyano, nitro, carboxamido, or hydroxy; and C.sub.1 -C.sub.6 alkanesulfonyloxy. R.sup.2 is .alpha.-OH or .beta.-OH and R.sup.6 is H or R.sup.2 and R.sup.6 together are carbonyl; the chemical intermediates; and processes for the preparation of these compounds and the intermediates thereto. Matrix metalloproteinases (MMP) are a family of zinc-containing calcium dependent proteinases, including stromelysins, collagenases, and gelatinases. These MMP enzymes are capable of degrading the proteinaceous components of connective tissue and appear to be involved in tissue remodeling, i.e., wound healing and connective tissue turnover. Unexpectedly, the mercaptoalcohols with the S-configuration at the hydroxyl-bearing carbon have been found to be at least 4 times more potent than the analogous (R)-alcohols both in vitro and in vivo in inhibiting the MMP enzyme.

    摘要: Known processes for producing 2-hydroxy-4-methylthiobutyric acid (MHA) use a liquid-liquid extraction or a combined liquid/liquid and solid/liquid phase separation to isolate MHA from a reaction mixture produced by hydrolysing MMP-cyanhydrine. These processes are either costly or produce waste that is difficult to dispose of. These disadvantages are eliminated by isolating MHA by solid/liquid separation. The reaction mixture is evaporated until a MHA-containing salt residue with little or no residual water is obtained the MHA-containing, salt residue is treated with an organic solvent to produce a suspension, solid components are separated from the thus obtained suspension until a MHA-containing solution is obtained, the organic solvent is removed from the MHA-containing solution until a MHA residue is obtained and if required the MHA residue is then conditioned by water admixture. Besides high quality MHA, this process produces marketable crystalline ammonium sulphate and/or hydrogenated ammonium sulphate. This process is useful for producing feedstuff supplements.
