Abstract: Embodiments of the invention are directed to new polymer linked multimeric guanosine-3?, 5?-cyclic monophosphate (cGMP) analogues that modulate the cGMP-signaling system, preferably having activating properties, and more preferably being activators of cGMP dependent protein kinase (PKG), and related monomeric precursors thereof. The invention is also directed to related monomeric compounds, which may also show modulating activity and/or may serve as monomeric precursors of the 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.

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.

Abstract: The invention relates to means and methods of targeted drug delivery of therapeutic agent to and across the blood-ocular barrier. In particular, the invention relates to cyclic guanosine-3?, 5?-monophosphate analogs as therapeutic agent for treating retinal diseases. The cGMPSs targeted to the blood-ocular barrier by glutathione-based ligands that facilitate the specific binding to and enhanced internalization by glutathione transporters present on the blood-ocular barrier. The glutathione-based ligands are conjugated to nanocontainers such as liposomes encapsulating the cGMPSs.

Abstract: A method of inhibiting the proliferation of cells, particularly cancerous cells, by contacting the cells with a phosphorothioate derivative of a cAMP modified at either or both the C-6 and C-8 positions of the adenine moiety, and pharmaceutical compositions therefor.

Abstract: New derivatives of S.sub.P - and R.sub.P -configures cyclic guanosine-3',5'-phosphorothioates and their physiologically and pharmaceutically acceptable salts according to the general formula ##STR1## are cell membrane permeable inhibitors (R.sub.P -isomers) and stimulators (S.sub.P -isomers) of cyclic GMP-dependent protein kinase which are resistant against phosphodiesterase degradation and suitable as ligands for affinity chromatography of cyclic nucleotide-dependent binding proteins.
