生物活性

製品説明	KNK437 is a pan-HSP inhibitor, which inhibits the synthesis of inducible HSPs, including HSP105, HSP72, and HSP40.
in vitro	KNK437 dose-dependently inhibits the acquisition of thermotolerance and the induction of various HSPs including HSP105, HSP70, and HSP40 in COLO 320DM (human colon carcinoma) cells.^[1] This compound and quercetin inhibits thermotolerance in a dose-dependent manner in PC-3 cells. It decreases heat-induced accumulation of Hsp70 mRNA and protein in PC-3 and LNCaP cells.^[2]
in vivo	KNK437 (200 mg/kg, i.p.) shows no antitumor effects and does not increase the thermosensitivity of nontolerant tumors. The same dose of this compound enhances the antitumor effects of fractionated heat treatment in a synergistic manner.^[3]

キナーゼアッセイ	Metabolic Labeling and Gel Electrophoresis
キナーゼアッセイ	COLO 320DM cells (200,000) are injected into each well of 12-well plastic plates 2 days before incubation in the presence of KNK437 for 1 h before heat shock. The cells are then heat-shocked at 42°C for 90 min or kept at 37°C for the same length of time and incubated at 37°C for 2 h. For metabolic labeling, cells are washed with PBS without Ca2+ or Mg2+ and incubated for 1 h with 1.22 MBq of [³⁵S]methionine in 250 μL of methionine-free DMEM supplemented with 10% dialyzed fetal bovine serum. After metabolic labeling, cells are washed twice with PBS and lysed in a buffer containing 1% NP40, 0.15 M NaCl, 50 mM Tris-HCl (pH 8.0), 5 mM EDTA, and protease inhibitors [0.2 mM 4-(2-aminoethyl)benzenesulfonyl fluoride hydrochloride, 2 mM N-ethylmaleimide, 1 μg/mL pepstatin, and 1 μg/mL leupeptin]. After centrifugation at 12,000×g for 20 min, cell extracts containing equal amounts of trichloroacetic acid-insoluble radioactivity are analyzed by two-dimensional gel electrophoresis (the one-dimensional gel electrophoresis is a nonequilibrium pH gradient gel electrophoresis, and the two-dimensional gel electrophoresis is 10% SDS-PAGE).
細胞アッセイ	細胞株	COLO 320DM cells
	濃度	100 μM
	反応時間	1 h
	実験の流れ	Thermotolerance is induced by incubating cells with 300 μM sodium arsenite for 90 min. Cells are preincubated with or without 100 μM KNK437 for 1 h before the sodium arsenite treatment. After treatment of the cells with sodium arsenite, cells are washed once with PBS and incubated at 37℃ for 5 h with or without this compound. The effects of this chemical on acquired thermotolerance are tested by heating the cells at 45°C for the indicated time. The surviving fraction is calculated as the plating efficiency of the treated cells divided by the plating efficiency of untreated control cells.
