Amine salts of 3-(2-methyl-pyrimidin-5-yl)-9-(5,6,7,8-tetrahydro-[1,8]-naphthyridin-2-yl) -nonanoic acid are potent antagonists of the integrin .alpha.v.beta.3 receptor and are useful for the prevention and/or treatment of osteoporosis and vascular restenosis, as well as conditions associated with excessive angiogenesis, such as macular degeneration, diabetic retinopathy, atherosclerosis, inflammatory arthritis, cancer, and metastatic tumor growth. The invention also relates to a process for the preparation of the novel salts as well as pharmaceutical compositions containing the salts and methods of using the salts. Also disclosed are 3(R)- and 3(S)-(2-methylpyrimidin-5-yl)-9-(5,6,7,8-tetrahydro-[1,8]naphthyridin-2-yl )-nonanoic acid in the form of a zwitterion trihydrate.

Amine salts of an integrin receptor antagonist

The present invention relates to novel nonanoic acid derivatives, their synthesis, and their use as .alpha.v integrin receptor antagonists. More particularly, the compounds of the present invention are antagonists of the integrin receptors .alpha.v.beta.3 and .alpha.v.beta.5 and are useful for inhibiting bone resorption, treating and preventing osteoporosis, and inhibiting vascular restenosis, diabetic retinopathy, macular degeneration, angiogenesis, atherosclerosis, inflammation, inflammatory arthritis, viral disease, cancer, and metastatic tumor growth.

.alpha.v integrin receptor antagonists

The tris(hydroxymethyl)aminomethane ("TRIS") salt of 3-(pyrimidin-5-yl)-9-(5,6,7,8-tetrahydro-[1,8]-naphthyridin-2-yl)-nonanoic acid is a potent antagonist of the integrin .alpha.v.beta.3 receptor and is useful for the prevention and/or treatment of osteoporosis and vascular restenosis, as well as conditions associated with excessive angiogenesis, such as macular degeneration, diabetic retinopathy, atherosclerosis, inflammatory arthritis, cancer, and metastatic tumor growth. The invention also relates to a process for the preparation of the novel salt as well as pharmaceutical compositions containing the salt and methods of using the salt.
