As part of a program to establish structure-activityrelationships for vanilloids, analogs of the pungent principle capsaicin, the alkyl chain portion of the parent structure (and relatedcompounds derived from homovanillic acid) was varied. In antinociceptive and antiinflammatory assays (rat and mouse hot plate and croton oil-inflamed mouse ear), compounds with widely varying alkyl chain structures

The present invention relates to novel topical compositions that are useful to enhance the overall appearance of the skin, such as reducing the appearance of fine lines and wrinkles. The present invention, which in brief summary, is a topical cosmetic composition having a spherical and/or substantially spherical optical diffuser particle and crosslinked silicone elastomer. In addition, the present invention includes methods of using such a topical composition and methods for cosmetically improving the appearance of skin.

An effective treatment method for improving the appearance of epithelia, such as lip epithelia and vaginal epithelia is provided. According to the present method, an effective amount of a composition containing retinoid, preferably in a cosmetically acceptable carrier, is topically applied to the vaginal or lip epithelia. The present invention also includes compositions for practicing the method.
Highly efficient synthesis of capsaicin analogues was developed using condensation of vanillylamine with acyl chlorides in a biphase H2O/CHCl3 System under mild conditions. For C-4-C-18 aliphatic or aromatic acyl chlorides, the yields were up to 93-96% with high purity after a simple work-up procedure, and only 1-1.16 equiv of acyl chloride was needed in the reaction.
