Abstract
The present invention provides compounds that will degrade under specified conditions, methods of using such compounds, and compositions comprising such compounds. The degradable compounds of the invention may be characterized by the labile —Si-A-C— groups present in the compounds (A representing an atom, such as O, N, or S, or a group, such as C═O). The compounds may be incorporated into a composition that further may include a polymeric matrix and/or a cargo component. A wide variety of cargo components may also be used in the present invention. In particular embodiments, the cargo component comprises a drug or other therapeutic agent. Accordingly, the invention particularly provides pharmaceutical formulations and methods of delivering a drug or other therapeutic material.
