Biological Activity
Description
In Vitro
Alvespimycin (17-DMAG) TFA inhibits the growth of the human cancer cell lines SKBR3 and SKOV3, which overexpress Hsp90 client protein Her2, and causes down-regulation of Her2 as well as induction of Hsp70 consistent with Hsp90 inhibition, for Her2 degradation with EC50 of 8 nM and 46 nM in SKBR3 and SKOV3 cells, respectively; for Hsp70 induction with EC50 of 4 nM and 14 nM in SKBR3 and SKOV3 cells, respectively[1].
Compared with the vehicle control, Alvespimycin (17-DMAG) TFA dose-dependent apoptosis (P<0.001 averaged across 24- and 48-hour time points) at concentrations of 50 nM to 500 nM, which represent pharmacologically attainable doses. Similar to many other agents, Alvespimycin (17-DMAG) TFA also demonstrates time-dependent apoptosis (P <0.001, averaged across all doses) in chronic lymphocytic leukemia (CLL) cells with extended exposure from 24 to 48 hours. In addition,Alvespimycin (17-DMAG) TFA is much more potent after 24 and 48 hours of treatment than 17-AAG[2].
