【 摘 要 】
Haspin is a serine/threonine kinase required for completion of normal mitosis that is highly expressed during cell proliferation, including in a number of neoplasms. Consequently, it has emerged as a potential therapeutic target in oncology. A high throughput screen of approximately 140,000 compounds identified an acridine analog as a potent haspin kinase inhibitor. Profiling against a panel of 270 kinases revealed that the compound also exhibited potent inhibitory activity for DYRK2, another serine/threonine kinase. An optimization study of the acridine series revealed that the structure-activity relationship (SAR) of the acridine series for haspin and DYRK2 inhibition had many similarities. However, several structural differences were noted that allowed generation of a potent haspin kinase inhibitor (33, IC(50) <60 nM) with 180fold selectivity over DYRK2. In addition, a moderately potent DYRK2 inhibitor (41, IC(50) <400 nM) with a 5.4-fold selectivity over haspin was also identified. (C) 2010 Elsevier Ltd. All rights reserved.
