  • Publication number: 20210308173
    Abstract: A composition including anethole trithione or a derivative thereof of formula (I), sulfobutyl ether-beta-cyclodextrin and optionally a co-solvent, wherein the ratio of the sulfobutyl ether-beta-cyclodextrin to the compound of formula (I) ranges from 10 to 400, preferably from 57 to 200. Also, the use of the composition as a drug, namely for the treatment and/or the prevention of free oxygen radical-related diseases. Further, a kit-of-parts and/or a medical device including the composition. Lastly, a method for solubilizing a compound of formula (I) in an aqueous medium.

  • Publication number: 20210228577
    Abstract: A complex of Ag, Zn, Cu, Pt, Au, oxides, hydroxides and salts thereof; with a cyclodextrin of formula (I). Advantageously, the complex further includes an organic therapeutic agent, preferably an antibiotic agent. The complexation advantageously maintains the metal: organic therapeutic agent molar ratio. Even more advantageously, the complexation enhances the intrinsic aqueous solubility of the metal-organic therapeutic agent association. Also, compositions, pharmaceutical compositions and adequate formulations and uses thereof as well as devices including a complex of the invention. Lastly, a method for improving the aqueous solubility of a metal selected from Ag, Zn, Cu, Pt, Au, Ru, As, Sb, Bi, Ti, V, Ni, Hg, Pb, Co, oxides, hydroxides and salts thereof by providing a reaction mixture including the metal, an aqueous medium and a cyclodextrin of formula (I).

  • Publication number: 20070197790
    Abstract: The invention relates to a method for the functionalization of a chemical molecule having at least two double bonds or containing a double bond which is conjugated with a structure that is rich in electrons in the presence of a TEMPO-type electrophoric mediator and a nucleophilic agent. The functionalization method can also include a system for electrochemical regeneration of the electrophoric mediator.
