Disclosed herein are conjugated polymers comprising a polymer and an all-trans retinoic acid (ATRA) prodrug covalently bound to the polymer by a hydrolysable linker L or a pharmaceutically acceptable salt thereof, and methods of using same to treat certain disorders. In an embodiment, the conjugated polymer comprises poly (vinyl alcohol) covalently bound to ATRA through an ester linkage.

Nano-fibular nanoparticle polymer-drug conjugate for sustained dermal delivery of retinoids

The present invention provides, among other things, multilayer film coating compositions, coated substrates and methods thereof. In some embodiments, a structure includes a substrate; and a multilayer film coated on the substrate, wherein adjacent layers of the multilayer film are associated with one another via one or more non-covalent interactions, wherein the multilayer film comprises a first nucleic acid agent present at a loading density, and further wherein the multilayer film is characterized in that, when the structure is placed on a subject so that the multilayer film contacts cells, the first nucleic acid agent is released with a profile characterized by a feature selected from the group consisting of 1) being a burst-free release; 2) being a sustained release; and 3) exhibiting in vitro and/or in vivo biological effectiveness.
