Biological Activity

KNK437 inhibit stress-induced synthesis of heat shock proteins (HSPs). KNK437 (100 μM) inhibits thermotolerance in COLO 320DM cells after the first heat treatment. KNK437 shows inhibitory effects on thermotolerance dose-dependently in COLO 320DM cells (0-200 μM) and HeLa S3 cells (100, 200 μM).

In vivo, KNK437 (62.5-400 mg/kg) recovers bodyweight losses of tumor-free CD-1 (ICR) mice. KNK437 (200 mg/kg) alone shows no antitumor effects and does not increase the thermosensitivity of nontolerant tumors.

Cell lines COLO 320DM cells
Preparation method Cells (1 × 105) are seeded in the flasks, incubated at 37°C for 48 h, and then heated by immersing the flasks in a water bath (45°C ± 0.05°C). KNK437 and quercetin are dissolved in DMSO before being added at the indicated concentrations. The final concentration of DMSO in each culture medium is 0.25% (v/v), irrespective of the concentrations of the drugs. The same concentration of DMSO is used as a control. Sodium arsenite is dissolved in PBS at a concentration of 80 mM and added to the medium. Cells are treated with 300 μM sodium arsenite at 37°C for 1.5 h, rinsed, and then incubated at 37°C for 5 h before 45°C heat challenge.
