SNX 2112

Research use only, not for human use.

SNX 2112 (PF 04928473) is a potent, selective Hsp90 inhibitor with binding IC50 of 30 nM for both HSP90α and HSP90β.

SNX 2112 (PF 04928473) is a potent, selective Hsp90 inhibitor with binding IC50 of 30 nM for both HSP90α and HSP90β; shows weak affinity for Hsp90 family members Grp94 and Trap-1 (IC50=0.8-4.2 uM); has properties and potency, including degradation of HER2, mutant EGFR, and other client proteins, inhibition of ERK and Akt activation, and induction of a Rb-dependent G1 arrest with subsequent apoptosis; the orally bioavailbe prodrug SNX-5422, inhibits MM cell growth and prolongs survival in a xenograft murine model.

SNX-2112 is an orally active Hsp90 inhibitor, with a Kd of 16 nM, and also induces Her-2 degradation, with an IC50 of 10?nM. SNX-2112 binds to Hsp90, with IC50s of 30 nM, 30 nM, 4.275 μM and 0.862 μM for Hsp90 α and β, Grp94 and Trap-1, respectively. SNX-2112 shows potent antiproliferative activity against various cancer cell types, with IC50s of 3 nM to 53 nM. SNX-2112 exhibits potent effects on Her2 and p-ERK stability in AU565 cells and p-S6 in A375 cells, with IC50s of 11?±?5, 41?±?12, and 1?±?0.6 nM, respectively. SNX-2112 also induces Hsp70 in A375 cells with an IC50 of 2?±?0.9 nM. In addition, SNX-2112 potently blocks signaling of Hsp90 clients, such as Akt, ERK, and NF-κB pathways in different cells. SNX-2112 inhibits multiple myeloma (MM) cell growth, including MM.1S, U266, INA-6, RPMI8226, OPM1, OPM2, MM.1R, and Dox40 MM cell lines, with IC50s of 52, 55, 19, 186, 89, 67, 93, and 53 nM at 48 hours, respectively. SNX-2112 (2.5-10 nM) also suppresses osteoclast formation, associated with down-regulation of ERK/c-fos and PU.1.
