Abstract: The present invention provides novel compounds of dinucleotide polyphosphates and the method of preventing or treating diseases or conditions associated with platelet aggregation. The method comprises administering systemically to a patient a pharmaceutical comprising a purinergic P2? receptor antagonist, in an amount effective to elevate its extracellular concentration to bind to P2? receptors and inhibit P2? receptor-mediated platelet aggregation. Methods of systemic administration include injection by intravenous, intramuscular, intrasternal and intravitreal routes, infusion, transdermal administration, oral administration, rectal administration and intra-operative instillation.

Abstract: The present invention relates to certain novel dinucleoside polyphosphates of general Formulae I, II and III, and formulations thereof which are selective ligands of the P2Y purinergic receptors. Applicants have discovered that dinucleoside polyphosphates of general Formulae I, II and III are effective in clearing retained mucous secretions, balancing tissue hydration and fluid secretion, and/or inhibiting or preventing early stages of platelet activation, platelet degranulation, and platelet aggregation.

Abstract: The present invention relates to certain novel dinucleotide polyphosphates of general Formulae I, II and III, and formulations thereof which are selective agonists of the P2Y purinergic receptors. They are useful in the prevention, management or treatment of diseases and disorders associated with abnormalities of tissue fluid secretion, hydration and clearance, including chronic obstructive pulmonary diseases (chronic bronchitis, PCD, cystic fibrosis, immobility-associated pneumonia), sinusitis, otitis media, nasolacrimal duct obstruction, dry eye disease, glaucoma, retinal degeneration, and edematous retinal disorders, including retinal detachment, vaginal dryness, and gastrointestinal tract disease. Finally, these novel dinucleotides may be useful for diagnostic purposes, such as the facilitation of sputum induction and expectoration for the analysis of respiratory tract secretions.

Abstract: Novel polymeric biologically inert compositions and their intermediates, as well as sunscreen formulations comprising them and making them invisible, are provided for broad range protection from ultraviolet radiation. Acryl polymers comprising at least two different ultraviolet absorbing moieties having different light absorbing ranges are employed in conjunction with other monomers to provide sunscreen polymers as microparticles. The polymer microparticles, once imbibed with carrier compounds, change the refractive index, thus providing invisible sunscreen formulations which offer enhanced protection without adverse physiological effects.

Abstract: Novel taxoids are provided having enhanced water solubility and/or improved pharmacological properties as compared to paclitaxel. The subject taxoids comprise a functional group attached to a paclitaxel at the C-2' and/or C-7 position by a linking group. Functional groups present in the subject taxoids may be hydrophilic chains, groups capable of in vivo conversion to hydrophilic chains, targeting moieties capable of specifically binding with cellular receptors and water soluble polymers of at least 5 kD. The subject taxoids find use in the treatment of hosts suffering from a cellular proliferative disease.

Abstract: Novel polymeric compositions and their intermediates are provided, providing for broad range protection from ultraviolet radiation. Acryl polymers comprising at least two different ultraviolet absorbing moieties having different light absorbing ranges are employed in conjunction with another hydrophilic monomer to provide sunscreen formulations for invisibility, and enhanced protection, without deleterious effects in the dermis.
