Description

TITLE OF INVENTION NOVEL HETEROCYCLIC COMPOUND, ITS PREPARATION METHOD, AND PHARMACEUTICAL COMPOSITION COMPRISING THE SAME TECHNICAL FIELD The present invention relates to a heterocyclic compound having a novel structure that can be used for the prevention or treatment of diseases caused by abnormality in a PRS (prolyl- tRNA synthetase) activity, a method for preparing the same, and a pharmaceutical composition comprising the same.
BACKGROUND OF ART PRS (prolyl-tRNA synthetase) is one of the aminoacyl-tRNA synthetase (ARS) family and serves to activate an amino acid for protein synthesis. That is, ARS performs a translational function to form aminoacyl adenylate (AA-AMP) and then transfer the activated amino acid to the 3-end of the corresponding tRNA. Since ARS plays an important role in the synthesis of protein, ARS inhibitors suppress the growth of all cells. Thus, ARS has been recognized as a promising target for a therapeutic agent for treating diseases that should suppress antibiotics or cell overexpression (Nature, 2013, 494:121-125).
PRS is present in, or functions as, a multi-synthetase complex (MSC) in the form of EPRS (Glutamyl-Prolyl-tRNA Synthetase). In particular, among various MSCs, EPRS functions as a translational silencer that suppresses the production of VEGF A (vascular endothelial growth factor A) which is a key factor in angiogenesis. In addition, it is reported that EPRS is closely related with various solid tumors (Nat. Rev. Cancer, 2011, 11, 708-718).
The only substance, known as the PRS inhibitor, is halofuginone. Halofuginone is a derivative of febrifugine derived from natural products and has anti-malarial effects and various anti-inflammatory effects. It can also be used as an animal feed additive. In addition, it has been reported that halofuginone increases the phosphorylation of GCN2 kinase through PRS inhibition, which induces ATF4 and CHOP expression, and thus promotes cell death (Nat. Chem. Biol. 2012, 8, 311-317). Currently, halofuginone is being clinically studied as anti-cancer agent, an anti- inflammatory agent (J Immunol, 2014, 192(5), 2167-76), therapeutic agents for the treatment of autoimmune diseases (Arthritis Rheumatol, 2014,66 (5), 1195-207), therapeutic agents for the treatment of fibrosis diseases (World J Gastroenterol, 2014,20 (40), 14778-14786), and the like (Bioorg. Med. Chem. 2014, 22, 1993-2004).
However, it has been reported that halofuginone acts on various targets and has a very severe toxicity and further there is a risk of genotoxicity (The EFSA Journal, 2003, 8: 1-45).
Therefore, discovering PRS inhibitors having higher safety to the human body among substances capable of inhibiting PRS like halofuginone has a significance in terms of developing an anti- cancer agent of the next generation that can be used as an antifibrosis agent, an anti-inflammatory agent, an autoimmune therapeutic agent alone or in combination with an existing targeted anti- cancer agent.
In this regard, the present inventors have conducted numerous studies to develop a novel compound with reduced toxicity while having a PRS enzyme inhibitory effect, and found that the compound having a novel structure which will be described later selectively inhibits the PRS, thereby completing the present invention. The compounds belonging to the present invention themselves have mainly a PRS enzyme inhibitory activity, but do not exclude a possibility of exhibiting a pharmacological action as an efficacious agent by a special body environment or by products of metabolic process, after absorption into the body.

H-NMR (500 MHz, DMSO-d ): δ 8.80 (s, 1H), 8.11 (s, 1H), 8.04 (s, 1H), 6.12 (m, 1H), .78 (m, 1H), 5.02 (d, 2H), 4.05 (m, 1H), 3.81 (m, 1H), 3.22 (m, 2H), 2.10 (m, 1H), 1.79 (m, 1H) Experimental Example: PRS enzyme activity inhibition experiment In order to confirm the biological activities of the compounds prepared in Examples, %inhibition or IC50 values of PRS enzyme (phosphoribosylpyrophosphate synthetase enzyme) activities were calculated.
Specifically, the portion corresponding to PRS in cDNA of EPRS was subcloned, and the obtained high-purity PRS protein was purified and used in the experiment. The compounds (1 μΜ) prepared in Examples were added into the reaction buffer (20 mM KP0 (pH 7.4), 6 mM MgAc, 5 mM ATP, 400 mg/mL tRNA, 0.5 mM DTT, 20 mCi[ H]proline (1 mCi/mL)) and allowed to react at 37°C for 5 to 10 minutes. The reaction was terminated with 3M paper that was in advance dried by addition of 5% TCA. The radioactivity was measured using a liquid scintillation counter.
% Inhibition and IC values of the respective compounds were calculated and analyzed using Microsoft Excel or Sigma Plot 8.0. The results are shown in Tables 1 to 3 below. In Tables 1 to 3, the results are divided into A, B and C according to the range of IC . The case where the derived IC is 100 nM or less is represented by "A", the case where the IC is 100 to 500nM is 50 50 represented by "B", and the case where the IC is 500 nM or higher is represented by "C".
