Tumor selectivity of Hsp90 inhibitors: the explanation remains elusive

ACS Chem Biol. 2006 Jun 20;1(5):279-84. doi: 10.1021/cb600224w.


Two recent papers attempt to solve both the tumor selectivity and the in vivo tumor accumulation profiles seen with some Hsp90 inhibitors. They spotlight the higher affinity of ansamycins' hydroquinone over the quinone form for Hsp90 and further discuss its possible contribution to ansamycins' tumor selectivity.
