Patent number: 9447108Abstract: The invention relates to new morphine derivatives deuterated at the 7,8-position of the morphine ring, furthermore to a process for the preparation thereof, and to pharmaceutical compositions comprising them. The new deuterated morphine derivatives show high and selective ?-opioid receptor binding activity leading to the benefit of higher analgesic activity at lower dosages inducing thereby reduced adverse effects compared to the hydrogenated derivatives. The compounds of the invention are useful for example in the treatment of pain or can be used as antitussive agents with a reduced risk of the possibility of drug abuse.Type: GrantFiled: April 14, 2014Date of Patent: September 20, 2016Assignee: Szegedi TudományegyetemInventors: Ferenc Fülöp, István Mándity

Patent number: 6982286Abstract: The present invention is directed to carbocyclic hydrazino compounds that function as inhibitors of copper-containing amine oxidases commonly known as semicarbazide-sensitive amine oxidases (SSAO), including the human SSAO known as Vascular Adhesion Protein-I (VAP-1). These SSAO inhibitors have therapeutic utility as drugs to treat conditions and diseases including, but not limited to, a number of inflammatory conditions and diseases (in particular chronic inflammatory conditions such as chronic arthritis, inflammatory bowel diseases, and chronic skin dermatoses), diseases related to carbohydrate metabolism and to aberrations in adipocyte differentiation or function and smooth muscle cell function, and vascular diseases. The novel compounds have the general formula: or a pharmaceutically acceptable solvate, hydrate, or salt thereof wherein R1 to R11 are as defined herein.Type: GrantFiled: July 12, 2001Date of Patent: January 3, 2006Assignee: Biotie Therapies Corp.Inventors: David John Smith, Ferenc Fülöp, Marjo Pihlavisto, László Lázár, Sakari Alaranta, Petri Vainio, Zsolt Szakonyi
