[Abstract]
HSP90 inhibition with Luminespib or Ganetespib treatment at 50 and 100 nM for 24 hours in three CMS4 cell lines with response to HSP90 inhibition (CACO2, LIM2099 and SW480) confirmed up-regulation of HSP70 and HSP40 at the protein level in treated versus untreated control cells (western blotting).
HSP90 inhibition affects ciliation. 24 h treatment with 100 nM AUY922 significantly affects ciliation, under 20% (left) O2 tension but not 5% O2 tension (right).

Beschreibung
Luminespib (VER-52296) is a potent HSP90 inhibitor with IC50s of 7.8 and 21 nM for HSP90α and HSP90β, respectively[1].
IC50 & Target
HSP90α
7.8 nM (IC50)
HSP90β
21 nM (IC50)
GRP94
535 nM (IC50)
TRAP-1
85 nM (IC50)
In Vitro
Luminespib is a potent and selective HSP90 inhibitor, with IC50s and Kis of 21 ± 16, 8.2 ± 0.7 nM against HSP90β and of 7.8 ± 1.8, 9.0 ± 5.0 nM for HSP90α. Luminespib shows weak activity against GRP94 and TRAP-1 wich IC50s of 535 ± 51 nM (Ki, 108 nM) and 85 ± 8 nM (Ki, 53 nM), respectively. Luminespib exhibits inhibitory effect on proliferation of various human tumor cell lines (2.3-49.6 nM), induces cell cycle arrest and apoptosis and depletes client proteins in human cancer cells (80 nM)[1]. Luminespib (100 nM) significantly reduces CD40L fibroblast-induced changes in immunophenotype and STAT3 signaling but with no effect on the viability of chronic lymphocytic leukemia (CLL) cells. Luminespib (500 nM) in combination with NSC 118218 more effectively induces apoptosis in cells in co-culture than either drug alone, and overcomes fibroblast-derived resistance to Hsp90 inhibitor[2]. Luminespib shows great inhibition of pancreatic cancer cells with IC50 of at 10 nM. Luminespib (10 nM) reduces the expression and the epidermal growth factor (EGF)-mediated activation of EGFR and substantially disrupts EGF signaling in terms of diminishing downstream phosphorylation of ERKThr202/Tyr204. Luminespib (10 nM) significantly blocks pancreatic cancer cell migration and invasion both in the absence and presence of EGF[3].

In Vivo
Luminespib (50, 75 mg/kg, i.p.) significantly inhibits tumor growth rate, reducing the mean weights of tumors on day 11 in human tumor xenografts[2]. Luminespib (50 mg/kg/week, 3×25 mg/kg/week) significantly reduces tumor growth rates and lowers tumor weights in the L3.6pl pancreatic cancer cell-bearing mice model[3].

To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Zellassay
[1]
Cell lines are grown in DMEM/10% FCS, 2 mM glutamine, and nonessential amino acids in a humidified atmosphere of 5% CO2 in air. All lines are free of Mycoplasma. Cell proliferation is determined using the SRB assay for tumor cells and prostate epithelial cells, the WST-1 assay for MCF10A and HB119, or an alkaline phosphatase assay for HUVEC and HDMEC. GI50 is the compound concentration inhibiting cell proliferation by 50% compared with vehicle controls. Active caspase-3/7 is measured using a homogenous caspase assay kit[1].

Mice[1]
For efficacy studies, human tumor xenografts are established s.c. in athymic mice. WM266.4 cells are also injected i.v. to generate experimental lung metastases and PC3LN3 prostate carcinoma cells are implanted into the prostates of male mice. Dosing by i.p. with Luminespib commences when tumors are well established. Tumor growth is monitored and at study end samples are harvested for analysis[1].

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
