  • Publication number: 20160228387
    Abstract: Provided herein are compositions and methods for reducing neurogeneration in a patient suffering from Parkinson's Disease, comprising administration of a composition comprising CoQ10 and polyoxyethanyl-a-tocopherylsebacate (PTS). The compositions of the invention have been shown to penetrate the blood-brain barrier in mammals, thus effecting delivery of CoQ10 directly to brain tissue. Beneficial effects of the treatment have been observed at lower doses of CoQ10 than previously described.

  • Patent number: 8524696
    Abstract: Water-soluble compositions comprising a lipophilic compound and a solubilizing agent of the general formula: {X—OOC—[(CH2)n—COO]m}p—Y??(I) wherein: X is a residue of a hydrophobic moiety, Y is a residue of a hydrophilic moiety, p is 1 or 2, m is 0 or 1, and n is an integer greater than or equal to 0 are disclosed. The lipophilic compound is preferably selected from the group consisting of water-insoluble ubiquinones, ubiquinols, vitamins, provitamins, polyene macrolide antibiotics, and mixtures thereof. The hydrophobic moiety is preferably a sterol or a tocopherol and the hydrophilic moiety is preferably a polyalkylene glycol. In some embodiments, the sterol is cholesterol or sitosterol, the tocopherol is ?-(+)-tocopherol, the polyalkylene glycol is a polyethylene glycol or its methyl monoether having an average molecular weight between 400 and 1000, p is equal to 1 or 2, m is equal to 0 or 1 and n is an integer between 2 and 18.
