The present application claims the benefit of priority based on Korean Patent Application No. 10-2020-0171958, filed on 10 Dec. 2020, the entire disclosure of which is incorporated as part of the specification.
The present invention relates to boronic acid compounds.
Proteasomes are a part of the intracellular machinery and degrade damaged or unnecessary proteins through the ubiquitin-proteasome pathway, thereby playing a significant role in cell function and growth. Proteasome inhibitors inhibit proteasomes so as to induce the excessive accumulation of abnormal proteins in cancer cells and induce the apoptosis of cancer cells.
Cancer cells are more sensitively affected by proteasome inhibitors than normal cells. Thus, by inhibiting the hydrolytic activity of the proteasomes, anticancer effects may be expected. In particular, the proteasome inhibitor selectively binds to and inhibits the chymotrypsin-like activity over the caspase-like activity within the proteasome to reduce side effects and effectively treat cancer.
The anticancer effects of this proteasome inhibitor were confirmed on hematologic malignancy, and Velcade has been marketed as a drug utilizing the proteasome inhibitor. However, side effects, such as drug resistance, have also been reported. Accordingly, research on a combined treatment method with this drug and an epidermal growth factor receptor (EGFR) kinase inhibitor (Korean Laid-open Patent No. 10-2007-0083719), a marker composition for diagnosing resistance to this drug (Korean Registration Patent No. 10-1471274), or the like, has been continuously performed. However, there are still needs to develop alternative substances with fewer side effects.
As a proteasome inhibitor drug, Carfilzomib selectively binds to the chymotrypsin-like activity over the caspase-like activity within the proteasome, but due to its irreversible binding, has a limitation in terms of utility.
Accordingly, the present inventors have continued research on a compound that selectively and reversibly binds to and inhibits the chymotrypsin-like activity, confirmed that a novel boronic acid compound selectively and reversibly binds to the chymotrypsin-like activity, and completed the present invention.
An object of the present invention is to provide a compound which may selectively and reversibly bind to and inhibit the chymotrypsin-like activity within the proteasome.
An aspect of the present invention provides a compound represented by the following Formula 1, a pharmaceutically acceptable salt thereof, or an isomer thereof:
Another aspect of the present invention provides a pharmaceutical composition for inhibiting the chymotrypsin-like activity within the proteasome, the composition comprising: the compound of Formula 1, the pharmaceutically acceptable salt thereof, or the isomer thereof, and a pharmaceutically acceptable carrier.
The boronic acid compound of the present invention may selectively and reversibly bind to and inhibit chymotrypsin-like activity over the caspase-like activity within the proteasome.
Since the boronic acid compound of the present invention has excellent selectivity for proteasome activity in cancer cells being targeted, serious side effects may be minimized. In addition, since the boronic acid compound of the present invention binds reversibly, it is detached thereafter, and the proteasome function can be restored. In this regard, there are advantages in high development potential and utilization.

The abilities to inhibit the proteasome activity of the compounds described in the Examples of the present invention and boronic acid drugs were evaluated as follows.
RPMI8226 cells, which is a multiple myeloma cell line, were cultured and then separated by a centrifuge, and washed twice with phosphate buffered saline (PBS). 20 mM of a tris-HCl (pH 8.0) buffer solution was added to the washed cells, and the cells were disrupted by a homogenizer and centrifuged to obtain S26 protein from the supernatant. Suc-Leu-Leu-Val-Tyr-AMC, for a fluorogenic substrate for the chymotrypsin-like activity of the proteasome, and Z-Leu-Leu-Glu-AMC, for a fluorogenic substrate for the caspase-like activity, were purchased from Calbiochem, EMD Millipore and used. Into each well of a 96-well plate (opaque, black round bottom), 20 ul of the S26 protein (final RPMI8226 cell extract concentration: 2 ug/well), 10 ul of S26 proteasome inhibitor serially diluted from 10 uM (final DMSO concentration: 0.5%), and 20 ul of the fluorogenic substrate for the proteasome chymotrypsin-like or caspase-like activity (final concentration: 20 uM) were added and mixed and allowed to react in a 37° C. incubator for 90 minutes. The fluorescence of the fluorogenic substrate was measured by FlexStation II Fluorometer (Molecular Devices). The fluorescence inhibited by the compound diluted at each concentration was measured as the relative percentage value for the amount obtained from the treatment only with the S26 protein and the fluorogenic substrate. IC50 (inhibitory concentration 50) was expressed in terms of a concentration that inhibits 50% of the maximum fluorescence induced by the fluorogenic substrate.
As confirmed in Table 1 above, it could be found that the compounds of the present invention have excellent ability to selectively bind to and inhibit the proteasome chymotrypsin-like activity.
