Abstract
Description
4-SUBSTITUTED FUSED BICYCLIC HETEROARYL DERIVATIVES CONTAINING ACRYLAMIDE, COMPOSITIONS THEREOF, AND USES THEREOFFIELD
[0001] Provided herein are compounds that can modulate the binding of Kelch-like ECH-associated protein 1 (KEAP1) to Cullin 3 (CUL3) -based E3 ubiquitin ligase as well as their pharmaceutical compositions and methods of use.BACKGROUND
[0002] NF-E2-related factor 2 (NRF2) is a transcription factor that can regulate genes involved in oxidative stress response, detoxification, metabolism, and inflammation. Abnormal NRF2 activation can enhance the survival and proliferation of cancer cells. Uncontrolled NRF2 activity grants cancer cells (such as lung cancers) significant resistance to anticancer drugs and reactive oxygen species (ROS) , while also steering them towards metabolic reprogramming.
[0003] The level of NRF2 can be controlled by the ubiquitination degradation pathway through the complexes formed by KEAP1 and Cullin 3 (CUL3) -based E3 ubiquitin ligase. KEAP1-CUL3 complexes function as NRF2-specific E3 ubiquitin ligases, guiding the polyubiquitination and subsequent degradation of NRF2 through the 26S proteasome.
[0004] Research has shown that KEAP1 can act as an adaptor that bridges NRF2 to the CUL3-based E3 ubiquitin ligase. Therefore, the KEAP1-NRF2 system has been investigated as a potential therapeutic target in cancer treatment. Compounds that mediate the binding activity of KEAP1 to CUL3, for example, KEAP1 activators enhancing the binding of KEAP1 to CUL3, can therefore have therapeutic effects in cancer patients with high NRF2 activity.SUMMARY

Recombinant human CUL3 protein (1-388) was expressed in sf9 cell using a baculovirus expression system.
[0270] Testing for the enhancement of binding of KEAP1 to CUL3 by various compounds disclosed herein was carried out at rt in assay buffer containing 10 mM HEPES Ph7.4, 150 mM NaCl, 0.5mM EDTA, 1mM DTT and 0.005%Tween-20. Compounds in DMSO were dispensed into wells of a black, 384-well plate (Corning 4514) using ECHO555 (Beckman) . The final concentration ranges of the test compounds were 0.25-5, 000 nM or 2.5-50, 000 nM. Five μL of KEAP1 protein solution was added to wells, and the plate was incubated for 1 hour at rt (RT) . After incubation for 1 hour at RT, 5 μL CUL3 solution was added to the wells to initiate reaction, and the plate was incubated. After 1 hour reaction, 5 μL detection reagent were added to the wells, and the plate was incubated for 1 hour. Detection reagent containing 0.025 test / μL Streptavidin-XL665 (PerkinElmer #610SAXLG) , 0.025 test / μL Mab Anti 6HIS-Tb (PerkinElmer #61HI2TLB) . HTRF was measured on a microplate reader (PHERAstar FSX, BMG labtech) . The EC50s were calculated based on activation of proteins interactions in the presence of increasing concentrations of test compounds, and the results were shown in Table 3.
[0271] Table 3 below describes the binding activity in the form of EC50 for compounds tested. “A” refers to an EC50 < 10 nM, “B” means 10 nM ≤ EC50 ≤ 20 nM, “C” means 20 nM < EC50 < 50 nM, and “D” means 50 nM ≤ EC50 ≤ 1 μM. “AA1” refers to 400 < Emax%≤ 1000, “BB1” means 300 ≤ Emax%≤400, “CC1” means 200< Emax%< 300, and “DD1” means 150 < Emax%≤200.
