  • Patent number: RE47448
    Abstract: Disclosed are thickener compositions composed of xanthan gum and a chelating agent, such as ascorbic acid. The chelating agent is present in an amount with respect to said xanthan such that, when said thickener composition is used to thicken a food product, at least one mineral selected from the group consisting of iron, zinc, and calcium present in said food product is relatively more bioavailable than the mineral would be in the absence of said chelating agent. The thickener composition finds particular applicability for use with baby formulas and breast milk intended for dysphagic infants.

  • Patent number: RE48226
    Abstract: The invention is directed to isomeric mixtures of cyclosporine analogues that are structurally similar to cyclosporine A. The mixtures possess enhanced efficacy and reduced toxicity over the individual isomers and over naturally occurring and other presently known cyclosporines and cyclosporine derivatives. Embodiments of the present invention are directed toward cis and trans-isomers of cyclosporin A analogs referred to as ISATX247, and derivatives thereof. Mixtures of ISATX247 isomers exhibit a combination of enhanced potency and reduced toxicity over the naturally occurring and presently known cyclosporins. ISATX247 isomers and alkylated, arylated, and deuterated derivatives are synthesized by stereoselective pathways where the particular conditions of a reaction determine the degree of stereoselectivity. The ratio of isomers in a mixture may range from about 10 to 90 percent by weight of the (E)-isomer to about 90 to 10 percent by weight of the (Z)-isomer, based on the total weight of the mixture.
