  • Publication number: 20240041783
    Abstract: The present invention is a surface treated drug-loaded solid (e.g., non-porous) microparticle that aggregates in vivo to form a consolidated larger particle for medical therapy. In one embodiment, the particles are used for ocular therapy. Processes for producing the surface treated microparticle and injectable formulations which include the surface treated microparticle are also provided. When used in the eye, long-term consistent intraocular delivery can be achieved without disrupting vision and minimizing undesirable inflammatory responses.

  • Publication number: 20220402964
    Abstract: Embodiments of the invention are directed to new equatorially modified polymer linked multimers of guanosine-3?, 5?-cyclic monophosphate (cGMP) analogues that inhibit the cGMP-signaling system. The invention is also directed to related monomeric compounds, which may serve as monomeric precursors of the multimers, and/or also show itself inhibitory activity and/or impact the inhibitory activity of the related multimers. The invention further relates to the use of such compounds as reagents for signal transduction research and as modulators of cyclic nucleotide-regulated binding proteins and isoenzymes thereof, and as ligands for affinity chromatography, for antibody production or for diagnostic applications, e.g., on chip surfaces.
