| + | [https://www.uniprot.org/uniprot/HS90A_HUMAN 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.<ref>PMID:15937123</ref> <ref>PMID:11274138</ref> | ||

| - | As 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. | ||
