Merck Co., Inc. - Rahway NJ

International Classification:

C07D40114

US Classification:

514256, 544333

Abstract:

Amine salts of -( -methyl-pyrimidin- -yl)- -( -tetrahydro-[ ]-naphthyridin- -yl)-nonanoic acid are potent antagonists of the integrin v 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 (R)- and (S)-( -methylpyrimidin- -yl)- -( -tetrahydro-[ ]naphthyridin- -yl)-nonanoic acid in the form of a zwitterion trihydrate.
