Novel and nonobvious compounds that function, alone or in combination, as nuclear hormone receptors for the stimulation and/or improvement of murine, mammalian skin. Specifically, beta-ionol analog and fatty acid analog compounds that are believed to function as RXR, RAR and/or PPAR receptor ligands to encourage skin differentiation and discourage excess skin proliferation. The present invention further relates to one or more products, consumer and otherwise, comprising the novel, nuclear hormone receptor ligands disclosed herein. The present invention additionally seeks to encompass methods of employing both the compounds of the present invention and the products incorporating the present compounds.

Push–pull structures with a pyrazine core and hexatriene chain: synthesis and light-emitting properties
In this paper, we describe the synthesis of various push–pull molecules with a central pyrazine unit connected to a hexatriene chain terminated by various p-substituted phenyl groups. The key steps involve metallation and subsequent transmetallation of 2-chloro and 2,6-dichloropyrazine followed by a Negishi cross-coupling reaction of the intermediate organozinc derivative with (2E,4E)-5-bromopentadienal
