PYRIMIDINE COMPOUNDS AND THEIR USE AS USP1 INHIBITORS
[0001] The present application claims the priority of international application No. PCT / CN2023 / 107498 filed on July 14, 2023, which is incorporated herein by reference in its entirety for all purpose.FIELD
[0002] Provided herein are certain pyrimidine heteroaromatic compounds, such as a compound of Formula (I) , as ubiquitin-specific-processing protease 1 (USP1) inhibitors, pharmaceutical compositions comprising the compounds, and method of use of the compounds or pharmaceutical compositions in the treatment of diseases or disorders.BACKGROUND
[0003] Ubiquitin (Ub) is a highly conserved 76-amino acid peptide that is post-transcriptionally attached to target proteins. The ubiquitin-proteasome system (UPS) is the major proteolytic system that controls protein degradation, and it also regulates many cellular processes in eukaryotic cells. Poly-ubiquitination via surface Lysine-48 (K48) or Lysine-11 (K11) residues of ubiquitin often leads to protein proteolysis through the 26S proteasome. In contrast, mono-ubiquitination or poly-ubiquitin chains linked through other lysines are always involved in DNA damage and repair, cell cycle progression, apoptosis, receptor-mediated endocytosis, and signal transduction. Similar to other posttranslational modifications, ubiquitination is a reversible process, and there is a family of enzymes, termed deubiquitinases (DUBs) , that act on ubiquitinated substrates to catalyze the removal of ubiquitin moieties.
[0004] One of the best-characterized human DUBs is ubiquitin-specific protease 1 (USP1) , which plays an important role in the cellular response to DNA damage. USP1, together with the cofactor UAF1 (USP1-associated factor 1) , acts during DNA repair processes to specifically to remove mono-ubiquitin signals. The mono-ubiquitinated FANCIFANCD2 heterodimer is one such substrate and is involved in the repair of DNA interstrand crosslinks via the Fanconi Anemia pathway. A second DNA repair-related process, translesion synthesis (TLS) , is also regulated by USP1, further supporting the crucial role of this DUB in the DNA damage response. The critical USP1 substrate in TLS is monoubiquitinated PCNA (Proliferating Cell Nuclear Antigen) . By reverting PCNA monoubiquitination, USP1 contributes to prevent unscheduled recruitment of TLS polymerases, and may thus help maintaining genome stability. Knockdown of USP1 results in elevated levels of FANCD2-Ub and PCNA-Ub and in increased cellular sensitivity to interstrand cross-linking agents, such as mitomycin C (MMC) . Mutations and altered expression of deubiquitinases have been found associated with many human diseases including cancers. There is a need for development of safe and effective treatments targeting deubiquitinases.SUMMARY

[0054] As used herein, and unless otherwise specified, the term “isomer” refers to different compounds that have the same molecular formula. “Stereoisomers” are isomers that differ only in the way the atoms are arranged in space. “Atropisomers” are stereoisomers from hindered rotation about single bonds. “Enantiomers” are a pair of stereoisomers that are non-superimposable mirror images of each other. A mixture of a pair of enantiomers in any proportion can be known as a “racemic” mixture. “Diastereoisomers” are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other. The absolute stereochemistry can be specified according to the Cahn-Ingold-Prelog R-Ssystem. When a compound is an enantiomer, the stereochemistry at each chiral carbon can be specified by either R or S. Resolved compounds whose absolute configuration is unknown can be designated (+) or (-) depending on the direction (dextro-or levorotatory) which they rotate plane polarized light at the wavelength of the sodium D line. However, the sign of optical rotation, (+) and (-) , is not related to the absolute configuration of the molecule, R and S. Certain compounds described herein contain one or more asymmetric centers and can thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that can be defined, in terms of absolute stereochemistry at each asymmetric atom, as (R) - or (S) -. The present chemical entities, pharmaceutical compositions and methods are meant to include all such possible isomers, including racemic mixtures, optically substantially pure forms and intermediate mixtures. Optically active (R) -and (S) -isomers can be prepared, for example, using chiral synthons or chiral reagents, or resolved using conventional techniques.
[0055] As used herein, and unless otherwise specified, the term “enantiomeric purity” or “enantiomer purity” refers to a qualitative or quantitative measure of a purified enantiomer. The enantiomeric purity of compounds described herein may be described in terms of enantiomeric excess (ee) , which indicates the degree to which a sample contains one enantiomer in greater amounts than the other. A racemic mixture has an ee of 0%, while a single completely pure enantiomer has an ee of 100%.

[0401] General procedure
[0402] The High-Performance Liquid Chromatography (HPLC) measurement was performed using a LC pump, a diode-array (DAD) or a UV detector and a column as specified in the respective methods. Flow from the column was brought to the Mass Spectrometer (MS) which was configured with an atmospheric pressure ion source. It is within the knowledge of the skilled person to set the tune parameters (e.g., scanning range, dwell time…) in order to obtain ions to allow the identification of the compound’s nominal monoisotopic molecular weight (MW) . Data acquisition was performed with appropriate software.
[0403] Compounds are described by their experimental retention times (Rt) and ions. If not specified differently in the table of data, the reported molecular ion corresponds to the [M+H] + (protonated molecule) and / or [M-H] - (deprotonated molecule) . All results were obtained with experimental uncertainties that are commonly associated with the method used.

[0433] USP1-UAF1 deubiquitination assay
[0434] Certain compounds provided herein were assessed by USP1-UAF1 deubiquitination assay. Deubiquitinase was measured by detecting the fluorescent signal generated when the amide bond between rhodamine and the C-terminal glycine of ubiquitin is hydrolyzed by USP1 using Ubiquitin-Rhodamine 110 (catalog U-555-050, R&D Systems) as an active substrate. Assay was conducted at a total 15 μl of reaction volume, including 0.05 nM USP1-UAF1 enzyme and assay buffer (50 mM HEPES pH 7.8, 0.5 mM EDTA, 100 mM NaCl, 0.1 mg / ml bovine serum albumin, I mM DTT, and 0.01%Tween-20) , and was commenced by adding a final concentration of 150 nM ubiquitin-rhodamine 110 substrate.
[0435] Deubiquitinase inhibitory assay was conducted with compounds dissolved in DMSO at a starting concentration of 10 μM. Dissolved compounds were added to 384-well microplate and premixed with USP1-UAF1 enzyme for 20 min incubation. Intrinsic fluorescence provided by compounds were measured as control prior to the addition of ubiquitin-rhodamine 110. Enzymatic reactions were started by adding ubiquitin-rhodamine 110 to the mixtures, and each well was read at 30 min by microplate reader ( TECAN) to detect the fluorescence intensity at 480 nm excitation / 530 nm emission.
[0436] All measured data were subtracted with control well, and IC50 values were calculated using four parameters dose-response inhibition model in GraphPad Prism 8.0.2 (La Jolla California USA, www. graphpad. com) .
[0437] Cell proliferation assay
[0438] For USP1 sensitivity, exponentially growing cells were seed in 96 or 384-well plates at very low density with the goal of not splitting for at least 7 days (typically 0.3k-1.2k cells / well) . Cells were plated on Day -1 and treated with DMSO or increasing concentrations of USP1 inhibitors on Day 0. At the end of the experiment, cell viability was estimated using Cell-Titer Glo (Promega) .
