PATENT PICKS

Polycyclic Compounds
7,307,078
Galderma Research & Development
Polycyclic compounds which modulate PPAR.gamma. type receptors and cosmetic/pharmaceutical compositions comprised thereof
This invention relates to a novel class of polycyclic compounds that are modulators of receptors of peroxisome proliferator-activated receptor type of subtype gamma (PPARγ). The invention also relates to a process for the preparation of these compounds and to their formulation into pharmaceutical compositions suited for human or veterinary medicine, or alternatively for cosmetic compositions.

High Foaming Hair Cleanser
7,307,050
Kao Corp.
Aqueous hair cleansing composition comprising a sulfate surfactant mixture and an amino-modified silicone
This invention relates to an aqueous hair cleansing composition that claims a good foaming property that produces abundant foam during shampooing, has a smooth foam quality, provides a smooth hair feel during rinsing, imparts hair with luster and manageability after drying, has good low-temperature stability, and that is substantially nonirritating. These properties are achieved by using polyoxyethylene added alkyl sulfates in which alkyl sulfates are distributed within a predetermined range on the smaller side of the number of moles of ethylene oxide addition, a specific amino-modified silicone derivative or a specific water-soluble cationic polymer, and a silicone oil having a small particle size in combination.

Fusion Protein for Transport
7,306,944
Polymer Ventures Inc.
Advanced cell-transducing transport domain-target protein-transport domain fusion protein and uses thereof
This invention provides a fusion protein that delivers a functional protein or peptide into a cell at enhanced efficiency. The fusion protein described is a transduction domain-target protein-transduction domain fusion protein, wherein the transduction domain is covalently bonded to each of the amino- and carboxyl-terminal ends of the target protein. Furthermore, the transduction domain comprises six to 12 amino acid residues, more than 75% of which are arginine or lysine residues. Green fluorescence protein and Cu/Zn-superoxide dismutase (SOD) are used as the target protein. Cosmetic compositions can be in the form of toilet water, gel, water-soluble liquid, o/w or w/o emulsions.
