Luminespib (also known as NVP AUY922; NVP AUY-922; AUY922; AUY-922; VER52296; VER-52296), a 4,5-diarylisoxazole derivative, is a 3rd generation HSP90 (heat shock protein 90) inhibitor with potential anticancer activity. In inhibits HSP90α/β with IC50s of 13 nM /21 nM in cell-free assays. Luminespib showed weaker potency against the HSP90 family members GRP94 and TRAP-1, and exhibits the tightest binding of any small-molecule HSP90 ligand. Structurally, luminespib is a derivative of 4,5-diarylisoxazole and a third-generation heat shock protein 90 (Hsp90) inhibitor with potential antineoplastic activity.
ln Vitro |
Luminespib inhibits HSP90 effectively and selectively, with IC50s and Kis of 21 ± 16, 8.2 ± 0.7 nM for HSP90β and 7.8 ± 1.8, 9.0 ± 5.0 nM for HSP90α. Luminespib has weak activity against GRP94 and TRAP-1, with IC50 values of 535 ± 51 nM (Ki, 108 nM) and 85 ± 8 nM (Ki, 53 nM), respectively. Luminespib inhibits the 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 while having no effect on the viability of CLL cells. Luminespib (500 nM) in combination with NSC 118218 induces apoptosis in co-culture cells more effectively than either drug alone, and it overcomes fibroblast resistance to Hsp90 inhibitors[2]. Luminespib shows great inhibition of pancreatic cancer cells with an IC50 of 10 nM. Luminespib (10 nM) significantly inhibits pancreatic cancer cell migration and invasion in both the absence and presence of EGF [3].

ln Vivo |
In human tumor xenografts, luminipespib (50, 75 mg/kg, ip) effectively suppresses the rate of tumor growth, lowering the mean weights of tumors on day 11[2]. In the L3.6pl pancreatic cancer cell-bearing mice model, luminescein (50 mg/kg/week, 3×25 mg/kg/week) dramatically lowers tumor weights and tumor growth rates[3].

Solubility in Formulation 1: ≥ 2.5 mg/mL (5.37 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.37 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
