Abstract: Tetrahydronaphthyridines of formula are disclosed. These compounds selectively inhibit ?V?3 without activating the ?V?3 receptor. They are useful for treating osteoporosis, acute myelogenous leukemia, sickle cell disease, focal segmental glomerulosclerosis, fibrosis, supravalvular aortic stenosis associated with Williams syndrome, tumors expressing ?V?3, tumor metastasis, bone resorption, T-cell lymphoma, retinal disease, age-related macular degeneration, diabetic retinitis, and herpes simplex virus infection. They may also be used for inhibiting tumor angiogenesis.

Abstract: The present invention relates to methods of treating sickle cell disease comprising reducing, in a subject in need of such treatment, the adherence between sickle RBCs and leukocytes. It is based, at least in part, on the discovery that leukocytes play a direct role in the initiation of venular occlusion. The present invention further provides for methods for identifying agents which decrease SS-RBC/leukocyte adherence and for animal models which may be used to further elucidate the mechanism of vaso-occlusion in sickle cell crises.

Abstract: The present invention relates to compounds of Formula P-I where the variables (e.g. R1, Y, A, R1, Ra, Ra?, Rb, Rb?, Rc, Rc?, Rd, Rd?, Re, or Re?) and compositions useful for inhibiting and/or reducing platelet deposition, adhesion and/or aggregation. The present invention further relates to methods for the treatment or prophylaxis of thrombotic disorders, including stroke, myocardial infarction, unstable angina, peripheral vascular disease, abrupt closure following angioplasty or stent placement and thrombosis as a result of vascular surgery.

Abstract: A method is provided of determining whether an individual has reduced ability to form platelet thrombi due to inhibition of platelet activation initiation, signal transduction and/or GPIIb/IIIa blockade. A blood sample is obtained from the individual being assessed. The blood sample is mixed in combination with 1) an anticoagulant; 2) sufficient buffer to maintain the pH and salt concentration of the anticoagulated blood within a range suitable for platelet aggregation; 3) a platelet GPIIb/IIIa receptor ligand immobilized on a solid surface; 4) one or more agents to enhance a signal transduction pathway and 5) a receptor activator. The combination is incubated under conditions for agglutinating particles. Platelet-mediated agglutination is assessed in the agitated mixture. The absence of agglutination indicates that the individual has a reduced ability to form platelet thrombi.
