BACKGROUND: There is increasing evidence suggesting that blocking aberrant Hedgehog (Hh) signaling can be a novel therapeutic avenue for the treatment of cancer. During the past decade, efforts from academic and industrial groups have led to the discovery of a variety of Hh pathway inhibitors. OBJECTIVE: This review covers the patent literature related to Hh pathway inhibitors for the treatment of proliferative diseases, regardless of their modes of action. METHODS: A comprehensive survey of the patent literature since 1999 is presented. RESULTS/CONCLUSION: Most reported Hh pathway inhibitors act on the key signaling transducer Smoothened (SMO). Screening of compound libraries using reporter and binding assays have identified a broad diversity of chemical structures that interact with SMO. These screening approaches, followed by conventional medicinal chemistry, have delivered important clinical drug candidates, such as GDC-0449 and XL-139. In addition, modification of the naturally occurring Veratrum alkaloid cyclopamine has resulted in various active analogues, including clinical drug candidate IPI-926. Although there are recent scientific literature reports of small molecules acting downstream of SMO, there is limited patent literature on this mode of Hh pathway inhibition.
