Abstract | C-beta -glycosides (I) containing a hydroxy-substituted hydrocarbyl group and their pharmaceutically acceptable salts are new. Excluded are C-beta -glycopyranoside-2(S),3-dihydroxypropane and C-beta -D-(2-deoxyglycopyranoside)-2(S),3-dihydroxypropane. C-beta -glycosides of formula (I) containing a hydroxy-substituted hydrocarbyl group and their pharmaceutically acceptable salts are new. Excluded are C-beta -glycopyranoside-2(S),3-dihydroxypropane and C-beta -D-(2-deoxyglycopyranoside)-2(S),3-dihydroxypropane. S : mono- or poly-saccharide of up to 20 sugar units as D series pyranose and/or furanose, including at least one free hydroxy and optionally one or more amino, optionally protected; R : 1-18C (perfluoro)alkyl or hydrofluoroalkyl, linear or branched, saturated or unsaturated, 3-11C cyclo(perfluoro)alkyl or cyclohydrofluoroalkyl, phenyl or benzyl, and the chain or rings may be interrupted by one or more of O, S, N or Si, and optionally substituted by one or more of OR 1, SR 1, N(R 1) 2, COOR 1, CONHR 1, cyano, halo, 1-18C (per)fluoroalkyl and/or 3-11C cycloalkyl, aryl or heterocyclic, optionally substituted; each R 1hydrogen, 1-30C (per)fluoroalkyl, hydroxy and/or hydrofluoroalkyl, linear or branched, saturated or unsaturated. An independent claim is also included for a method of preparing (I) by reducing the corresponding ketone S-CO-R (II). [Image] ACTIVITY : Dermatological; Vulnerary. MECHANISM OF ACTION : (I) stimulate synthesis of glycosaminoglycans (GAG) that contain D-glucosamine and/or N-acetylglucosamine residues, especially hyaluronic acid (HA), and/or of proteoglycans by fibroblasts and keratinocytes. It also modulates the activity of growth factors and cytokines. HA synthesis in a culture of human fibroblasts was detected by incorporation of radiolabeled glucosamine. The mean number of counts per minute (cpm) after 72 hours was 5010; compare 40770 (814 % of control) for a culture containing 3 mM C-beta -D-xylopyranoside-2(S)-hydroxypropane. |
