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.

Treatment of neurodegenerative diseases is achieved using small molecule purine scaffold compounds that inhibit Hsp90 and that possess the ability to cross the blood-brain barrier or are other wise delivered to the brain.
摘要:
A method for evaluation of molecules to identify those that can act as therapeutic inhibitors of Hsp90 makes use of a fluorescence polarization (FP) assay and a cell based assay, either individually or in combination. The FP assay uses a fluorescently-labeled Hsp90 binding agent and measure the degree of fluorescence polarization relative to the standard. A decrease in the degree of polarization indicates that fluorescently-labeled Hsp90 binding agent has been wholly or partially displaced by a candidate molecule, and identifies the molecule as having activity as an inhibitor of Hsp90. The cell based assay tests for decrease is an Hsp90-dependent activity of normal or tumor cells.

摘要:
This invention concerns a method for selecting an inhibitor of a cancer-implicated pathway or of a component of a cancer-implicated pathway for coadministration, with an inhibitor of HSP90, to a subject suffering from a cancer which comprises the following steps: (a) contacting a sample containing cancer cells from a subject with an inhibitor of HSP90 or an analog, homolog or derivative of an inhibitor of HSP90 under conditions such that one or more cancer pathway components present in the sample bind to the HSP90 inhibitor or the analog, homolog or derivative of the HSP90 inhibitor; (b) detecting pathway components bound to the HSP90 inhibitor or to the analog, homolog or derivative of the HSP90 inhibitor; (c) analyzing the pathway components detected in step (b) so as to identify a pathway which includes the components detected in step (b) and additional components of such pathway; and (d) selecting an inhibitor of the pathway or of a pathway component identified in step (c). This invention further concerns a method of treating a cancer patient by coadministering an inhibitor of HSP90 and an inhibitor of a cancer-implicated pathway or component thereof.
