Inhibition of the pore-forming protein perforin by a series of aryl-substituted isobenzofuran-1(3H)-ones
摘要:
An aryl-substituted isobenzofuran-1(3H)-one lead compound was identified from a high throughput screen designed to find inhibitors of the lymphocyte pore-forming protein perforin. A series of analogs were then designed and prepared, exploring structure-activity relationships through variation of 2-thioxoimidazolidin-4-one and furan subunits on an isobenzofuranone core. The ability of the resulting compounds to inhibit the lytic activity of both isolated perforin protein and perforin delivered in situ by intact KHYG-1 natural killer effector cells was determined. Several compounds showed excellent activity at concentrations that were non-toxic to the killer cells. This series represents a significant improvement on previous classes of compounds, being substantially more potent and largely retaining activity in the presence of serum. (C) 2011 Elsevier Ltd.

Thiazolidinedione compounds, compositions, and methods of inhibiting telomerase activity in vitro and treatment of telomerase mediated conditions or diseases ex vivo and in vivo are provided. The methods, compounds and compositions of the invention may be employed alone, or in combination with other pharmacologically active agents in the treatment of conditions or diseases mediated by telomerase activity, such as in the treatment of cancer. Also disclosed are methods for assaying or screening for inhibitors of telomerase activity.
