HSP90 N-terminal domain in complex with 1-{4-[(2R)-1-(5-chloro-2,4-dihydroxybenzoyl)pyrrolidin-2-yl]benzyl}-3,3-difluoropyrrolidiniumHSP90 N-terminal domain in complex with 1-{4-[(2R)-1-(5-chloro-2,4-dihydroxybenzoyl)pyrrolidin-2-yl]benzyl}-3,3-difluoropyrrolidinium
Structural highlights
Function[HS90A_HUMAN] Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedAs part of an oncology chemistry program directed toward discovery of orally bioavailable inhibitors of the 90 kDa heat shock protein (Hsp90), several solution-phase libraries were designed and prepared. A 2 x 89 library of racemic resorcinol amides was prepared affording 131 purified compounds. After evaluation in a binding assay, followed by an AKT-Luminex cellular assay, three potent analogs had functional activity between 0.1 and 0.3 microM. Resolution by preparative chiral SFC chromatography led to (+)-15, (+)-16, and (+)-17 having functional IC(50) = 27, 43, and 190 nM, respectively. (+)-15 exhibited high clearance in human hepatocytes driven primarily by glucuronidation as confirmed by metabolite identification. A second 8 x 14 exploratory library was designed to investigate heterocyclic replacements of the resorcinol ring. The second library highlights the use of the (-)-sparteine-mediated enantioselective Pd-catalyzed alpha-arylation of N-Boc-pyrrolidine to prepare chiral 2-arylpyrrolidines in parallel.
