    摘要: Bifunctional molecules comprising two hsp-binding moieties which bind to hsp90 in the pocket to which ansamycin antibiotics bind connected via a linker are effective for inducing the degradation and/or inhibition of HER-family tyrosine kinases. For example, a compound of two geldanamycin moities joined by a four-carbon linker provides selective degradation of HER-family tyrosine kinases, without substantially affecting other kinases. These compounds can be used for treatment of HER-positive cancers with reduced toxicity, since these compounds potently kill cancer cells but affect fewer proteins than geldanamycin.

    摘要: Structural differences in binding pockets of members of the HSP90 family can be exploited to achieve differential degradation of kinases and other signaling proteins through the use of designed small molecules which interact with the N-terminal binding pocket with an affinity which is greater than ADP and different from the ansamycin antibiotics for at least one species of the HSP90 family. Moreover, these small molecules can be designed to be soluble in aqueous media, thus providing a further advantage over the use of ansamycin antibiotics. Pharmaceutical compositions can be formulated containing a pharmaceutically acceptable carrier and a molecule that includes a binding moiety which binds to the N-terminal pocket of at least one member of the HSP90 family of proteins. Such binding moieties were found to have antiproliferative activity against tumor cells which are dependent on proteins requiring chaperones of the HSP90 family for their function. Different chemical species have different activity, however, allowing the selection of, for example Her2 degradation without degradation of Raf kinase. Thus, the binding moieties possess an inherent targeting capacity. In addition, the small molecules can be linked to targeting moieties to provide targeting of the activity to specific classes of cells. Thus, the invention further provides a method for treatment of diseases, including cancers, by administration of these compositions. Dimeric forms of the binding moieties may also be employed.

    摘要: The present invention provides methods and compositions for the detection of novel BRAF splice variants that mediate resistance to BRAF and/or pan-RAF inhibitors. In particular, the invention provides PCR primer(s) to be used in the disclosed methods of detection. In some embodiments, the compositions and methods of the present invention are used to predict resistance to BRAF and/or pan-RAF inhibitors in a subject suffering from or suspected of having cancer and further provides alternative treatment strategy(ies) for a subject predicted to be resistant to BRAF and/or pan-RAF inhibitors. In a further embodiment, methods and composition for the identification of novel agents useful to overcome resistance to BRAF and/or pan-RAF inhibitors are disclosed. The present invention also provides isolated polynucleotide sequences of novel 5′ BRAF splice variant(s) and proteins produced from such polynucleotide sequences as well as cell line(s) that endogenously or exogenously express the splice variant(s).
