Abstract:

A cholesterol-regulating complex of SIRT1 and LXR and methods of use are disclosed. SIRT1 forms a complex with LXR bound to an LXR element. Methods of forming the complex, identifying an agent that modulates formation of the complex, increasing the ratio of cholesterol bound to high density lipoprotein (HDL) to total cholesterol in the plasma of a mammal, promoting ABCA1-mediated cholesterol efflux from a mammalian cell, treating a subject deemed to have a level of SIRT1 activity that is below normal, assessing whether a candidate substance modulates an LXR-dependent process, and assessing whether a candidate substance modulates an SIRT1-dependent effect of an LXR are disclosed.

Ciba-Geigy Corporation - Ardsley NY

International Classification:

C08F23008

US Classification:

526279

Abstract:

A new polymer, the feed monomers and molar percents of which, exclusive of a polymerization initiator and crosslinker, are: A. (I) 42 mole % to 58 mole % of a siloxy silane of formula I, (II) 42 mole % to 58 mole % of an unsubstituted alkyl (meth)acrylate of formula II, (III) 0 to 5 mole % of a Group A monomer, and (IV) 0 to 16 mole % of an additional vinylic copolymerizable monomer; B. (I) 42 mole % to 58 mole % of a siloxy silane of formula I, (II) 21 mole % up to less than 42 mole % of an unsubstituted alkyl (meth)acrylate of formula II, (III) 0 to 5 mole % of a Group A monomer, and (IV) 0 to 29 mole % of an additional vinylic copolymerizable monomer, or C. (I) 16 mole % up to less than 42 mole % of a siloxy silane of formula I, (II) 42 mole % of 58 mole % of an unsubstituted alkyl (meth)acrylate of formula II, (III) 0 to 5 mole % of a Group A monomer, and (IV) 0 to 36 mole % of an additional vinylic copolymerizable monomer, where formula I is ##STR1## where formula II is ##STR2## where Group A is a vinylic acid or a (meth)acrylate as defined herein. Methods of manufacture of the polymer and the use thereof as a pressure adhesive, especially a transdermal and/or transmucosal delivery system pressure sensitive adhesive, are also claimed.
