Publication number: 20140051703Abstract: The present invention relates to thiopyrimidine-based compounds that are inhibitors of protein kinases including JAK kinases. In particular, the compounds are selective for JAK1, JAK2 or JAK3 kinases and combinations thereof such as JAK1 and JAK2. The kinase inhibitors can be used in the treatment of kinase associated diseases such as immunological and inflammatory diseases including organ transplants; hyperproliferative diseases including cancer and myeloproliferative diseases; viral diseases; metabolic diseases and vascular diseases.Type: ApplicationFiled: April 11, 2013Publication date: February 20, 2014Applicant: Cytopia Research Pty Ltd.Inventors: David Gerard BOURKE, Xianyong Bu, Christopher John Burns, Anthony Nicholas Cuzzupe, John Thomas Feutrill, Tracy Leah Nero, Beata Maria Blannin, Jun Zeng, Shaun Patrick Gaynor

Patent number: 7593820Abstract: The present invention relates to X-ray crystallography studies of a human Janus Kinase 2 (JAK2) domain. More particularly, it relates to the crystal structure of a JAK2 kinase domain bound to a inhibitor. The invention further relates to the use of the crystal and related structural information to select and screen for compounds that interact with JAK2 and related proteins and to compounds that could be used for the treatment of diseases mediated by inappropriate JAK2 activity.Type: GrantFiled: October 11, 2005Date of Patent: September 22, 2009Assignee: Cytopia Research Pty LtdInventors: Andrew Frederick Wilks, Christopher John Burns, Emmanuelle Fantino, Isabelle Lucet, Jamie Rossjohn, Michelle Leanne Styles
