Description

Pyrimidine derivatives as Wee1 inhibitors
Technical Field
The invention belongs to the field of pharmaceutical chemistry, and particularly relates to a novel compound with a Wee1 kinase inhibition effect, a preparation method thereof and application of the compound in preparation of antitumor drugs.
Background
Wee-1 protein kinase is an important negative regulatory protein in cell cycle checkpoints. The cell cycle checkpoints include the G1 phase checkpoint for the transition from G1 (cell resting phase) to S phase (DNA synthesis phase), the G2 phase checkpoint for the transition from G2 (cell division preparatory phase) to M (cell division phase) and the spindle checkpoint for the transition from M phase metaphase to anaphase. Wee-1 protein kinase plays an important role in the checkpoint at G2. Cell entry into M phase is dependent on CDK1 kinase activity, Wee-1 inhibits CDK1 activity by phosphorylating Tyr15 of CDK1 protein, preventing cells from entering M phase (cell division phase). Polo kinase phosphorylates Wee-1, activates degradation of Wee-1 protein, and promotes cells to enter M phase. It can be seen that Wee-1 kinase activity determines the activity of the G2 checkpoint and, in turn, regulates the G2 to M phase transition in cells [ Cell Cycle,2013.12(19): p.3159-64 ].
Cell cycle checkpoints are activated primarily following DNA damage and play an important role in the repair of DNA in cells. Normal activation of cell cycle checkpoints blocks the cell cycle promoting DNA repair. Inhibiting the function of check point, the DNA damage can not be repaired, and the cell is apoptotic. Compared with normal cells, a plurality of tumor cells repair DNA damage and avoid apoptosis mainly depending on the activation of a G2 stage checkpoint because the function of a P53 protein which is an important protein of the G1 stage checkpoint is damaged. Therefore, inhibition of the checkpoint at stage G2 selectively kills tumor cells. While the role of Wee-1 kinase activity in the checkpoint at stage G2 suggests that Wee-1 kinase determines the repair or death of tumor cells after DNA damage, inhibition of Wee-1 activity promotes the entry of unrepaired tumor cells into stage M after DNA damage, inducing apoptosis [ Curr Clin Pharmacol,2010.5(3): p.186-91 ].
In addition to its role in the G2 checkpoint, Wee-1 has been implicated in DNA synthesis, DNA homology repair, post-translational modification of histones, and other functions that are closely related to tumorigenesis and development [ J Cell Biol,2011.194(4): p.567-79 ]. In a large number of tumors including liver, breast, cervical, melanoma and lung cancers [ PLoS One,2009.4(4): p.e5120 ]; hepatology,2003.37(3): p.534-43; mol Cancer,2014.13: p.72 ], Wee-1 expression was greatly elevated. While the high expression of Wee-1 is positively correlated with the poor development and prognosis of tumors, suggesting that Wee-1 kinase may be involved in the development and development of tumors. Studies in vitro cell models and in vivo animal models have shown that inhibition of Wee-1 activity while inducing DNA damage can significantly inhibit the growth of a variety of tumors [ Cancer Biol Ther,2010.9(7): p.514-22; mol Cancer Ther,2009.8(11): p.2992-3000 ].
Therefore, the development of specific, small molecule inhibitors of highly active Wee-1 kinase would be of significant clinical value for tumor therapy, especially in targeting tumors with an impaired G1 checkpoint such as a P53 deletion.

Definitions and explanations
As used herein, the following terms and phrases are intended to have the following meanings, unless otherwise indicated. A particular term or phrase, unless specifically defined otherwise, should not be considered as indefinite or unclear, but rather construed according to a common definition, when appearing herein with a trade name, is intended to refer to its corresponding commodity or its active ingredient. The term "pharmaceutically acceptable" as used herein is intended to refer to those compounds, compositions and/or formulations which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.
The term "pharmaceutically acceptable salt" refers to a form of a compound that does not cause significant irritation to the organism to which it is administered and does not abrogate the biological activity and properties of the compound. In certain particular aspects, pharmaceutically acceptable salts are obtained by reacting a compound of formula (1A) or formula (1B) with an acid, such as an inorganic acid, e.g., hydrochloric acid, hydrobromic acid, hydrofluoric acid, sulfuric acid, phosphoric acid, nitric acid, phosphoric acid, etc., an organic acid, e.g., formic acid, acetic acid, propionic acid, oxalic acid, trifluoroacetic acid, malonic acid, succinic acid, fumaric acid, maleic acid, lactic acid, malic acid, tartaric acid, citric acid, picric acid, methanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, etc., and an acidic amino acid, e.g., aspartic acid, glutamic acid, etc.
References to pharmaceutically acceptable salts are understood to include solvent addition forms or crystalline forms, especially solvates or polymorphs. Solvates contain either stoichiometric or non-stoichiometric amounts of solvent and are selectively formed during crystallization with pharmaceutically acceptable solvents such as water, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is ethanol. Solvates of the compounds of formula (1A) or formula (1B) are conveniently prepared or formed according to the methods described herein. For example, the hydrate of the compound of formula (1A) or (1B) is conveniently prepared by recrystallization from a mixed solvent of water/organic solvent, using an organic solvent including, but not limited to, acetonitrile, tetrahydrofuran, ethanol or methanol. In addition, the compounds mentioned herein can exist in unsolvated as well as solvated forms. In general, the solvated forms are considered equivalent to unsolvated forms for purposes of the compounds and methods provided herein.
In other embodiments, the compounds of formula (1A) or formula (1B) are prepared in different forms, including, but not limited to, amorphous, pulverized, and nano-sized forms. In addition, the compound of formula (1A) or formula (1B) includes crystalline forms, and may also be polymorphic forms. Polymorphs include different lattice arrangements of the same elemental composition of a compound. Polymorphs typically have different X-ray diffraction patterns, infrared spectra, melting points, densities, hardness, crystal forms, optical and electrical properties, stability and solubility. Different factors such as recrystallization solvent, crystallization rate and storage temperature may cause a single crystal form to dominate.
In another aspect, the compounds of formula (1A) or formula (1B) have one or more stereogenic centers and thus occur as racemates, racemic mixtures, single enantiomers, diastereomeric compounds and individual diastereomers. Asymmetric centers that may be present depend on the nature of the various substituents on the molecule. Each such asymmetric center will independently produce two optical isomers and all possible optical isomers and diastereomeric mixtures and pure or partially pure compounds are included within the scope of the invention. The present invention is meant to include all such isomeric forms of these compounds.
