In Vitro

VER-50589 is a Hsp90 inhibitor, with an IC₅₀ of 21 nM and a K_d of 4.5 nM. VER-50589 inhibits intrinsic ATPase of full-length recombinant yeast Hsp90, with an IC₅₀ of 143 ± 23 nM in the presence of 400 μM ATP. VER-50589 shows antiproliferative activities against various human cancer cells, with the lowest GI₅₀ of 32.7 ± 0.2 nM for CH1 human ovarian cells, and mean GI₅₀ of 78 ± 15 nM. VER-50589 suppressses the proliferation of human umbilical vein endothelial cells (HUVEC) with GI₅₀ value of 19 ± 2.4 nM, and shows higher GI₅₀s against nontumorigenic human breast (MCF10a) and prostate (PNT2) epithelial cells. Furthermore, VER-50589 displays no differences in cellular activities of isogenic cell lines, and these activities are independent of NQO1 expression. VER-50589 also causes G1 and G2-M block (115 or 575 nM) and induces cytostasis in HCT116 colon cancer cells. In addition, VER-50589 causes great uptake in HCT116 cells^[1].

In Vivo

VER-50589 (4 mg/kg, i.p.) exerts a complete HSP90 inhibition in the athymic mice bearing well-established OVCAR3 human ovarian ascites tumors. VER-50589 (100 mg/kg, i.p.) shows reduced tumor volume and tumor weights in the HCT116 colon carcinoma xenografts compared to the control mice group^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
