Publication Abstract from PubMed

Novel small molecule inhibitors of heat shock protein 90 (Hsp90) were discovered with the help of a fragment based drug discovery approach (FBDD) and subsequent optimization with a combination of structure guided design, parallel synthesis and application of medicinal chemistry principles. These efforts led to the identification of compound 18 (NMS-E973), which displayed significant efficacy in a human ovarian A2780 xenograft tumor model, with a mechanism of action confirmed in vivo by typical modulation of known Hsp90 client proteins, and with a favorable pharmacokinetic and safety profile.

Discovery of NMS-E973 as novel, selective and potent inhibitor of heat shock protein 90 (Hsp90).,Brasca MG, Mantegani S, Amboldi N, Bindi S, Caronni D, Casale E, Ceccarelli W, Colombo N, De Ponti A, Donati D, Ermoli A, Fachin G, Felder ER, Ferguson RD, Fiorelli C, Guanci M, Isacchi A, Pesenti E, Polucci P, Riceputi L, Sola F, Visco C, Zuccotto F, Fogliatto G Bioorg Med Chem. 2013 Nov 15;21(22):7047-63. doi: 10.1016/j.bmc.2013.09.018.
