Adarotene belongs to the so-called class of atypical retinoids. The presence of the phenolic hydroxyl group on Adarotene structure allows a rapid O-glucuronidation as a major mechanism of elimination of the drug, favoring a fast excretion of its glucuronide metabolite in the urines. A series of ether, carbamate and ester derivatives was synthesized. All of them were studied and evaluated for their stability at different pH. The cytotoxic activity in vitro on NCI-H460 non-small cell lung carcinoma and A2780 ovarian tumor cell lines was also tested. A potential back-up of Adarotene has been selected to be evaluated in tumor models. (C) 2012 Elsevier Ltd. All rights reserved.

The present invention addresses the need for an improved delivery system that is able to specifically target the skin for improved bioavailability and minimization of side effects resulting from administration of the active ingredient or ingredients. One aspect of the present invention is a targeting composition comprising: (1) a skin care agent or an agent that is a cosmeceutical agent; (2) an intermediate release linker bound to the skin care agent or cosmeceutical agent; (3) a targeting moiety bound to the intermediate release linker, the targeting moiety for binding the targeting composition to native collagen fibers; and (4) optionally, a carrier component to enhance delivery to the skin. The present invention also describes methods of use of these targeting compositions.
