Bioactivity

SNX-2112 (PF 04928473) is an orally active Hsp90 inhibitor, with a Kd of 16 nM for Hsp90 and IC50s of 30 nM, 30 nM for Hsp90 α and Hsp90 β, also induces Her-2 degradation, and inhibits Grp94 and Trap-1, with IC50s of 10 nM, 4.275 μM and 0.862 μM, respectively[1]. SNX-2112 (PF 04928473) binds Hsp90 isoforms Hsp90α, Hsp90β and Hsp90b1/Grp94 with Kds of 4 nM, 6 nM and 484 nM, respectively[2].

Invitro

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[3]. 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[1]. 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[3]. 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[4]. 0 --> SNX-2112 相关抗体:
