Nuclear factor-kappa B inhibitors; a patent review (2006-2010)

Introduction: Nuclear factor (NF)-kappa B, as transcription factor, is linked to the expression of various genes and plays an essential role in immune and inflammatory responses. Abnormal NF-kappa B signaling results in human diseases, such as immune disorders, inflammation and various cancers. Therefore, regulation of NF-kappa B may treat or improve the symptoms in human disorders. Areas covered: This review provides information on recent NF-kappa B inhibitor-related patents from 2006 to 2010. The patents are explained and categorized by mechanism. The reader will gain an understanding of NF-kappa B function and the structure and biological activity of recently developed NF-kappa B inhibitors that may be new drug candidates. Expert opinion: NF-kappa B plays an essential role in the human body and thus regulation of NF-kappa B is very important for the treatment of diseases. Furthermore, patented compounds and peptides are available as lead compounds in drug development studies.
