[0013] WEE1 is a tyrosine kinase that is a key component of the ATR-mediated G2 cell cycle checkpoint, which blocks the initiation of mitosis in response to cellular DNA damage. ATR phosphorylates and activates CHK1, which then activates WEE1, leading to the selective phosphorylation of cyclin-dependent kinase 1 (CDK1) at Tyr15, thereby stabilizing the CDK1-cyclin B complex and arresting cell cycle progression. This process confers a survival advantage by allowing tumor cells time to repair damaged DNA before the onset of mitosis. Inhibition of WEE1 inhibits the G2 checkpoint, causing cancer cells with DNA damage to enter unscheduled mitosis and undergo cell death by mitotic apoptosis. Therefore, inhibition of WEE1 has the potential to sensitize tumors to DNA-damaging agents such as cisplatin and induce tumor cell death.

[0014] definition Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. All patents, applications, published applications, and other publications referenced herein are incorporated by reference in their entirety unless stated otherwise. In the event that there are a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

[0015] Unless otherwise specified, as used herein, the term "crystalline" and related terms, when used to describe a substance, component, product, or form, means that the substance, component, product, or form is substantially crystalline, for example, as determined by X-ray diffraction (see, e.g., J. Chem. Soc. 1999, 144:111-112; J. Chem. Soc. 1999, 144:111-112).

[0016] As used herein, unless otherwise specified, the terms "about" and "approximately," when used in connection with a dose, amount, or weight percent of a component of a composition or dosage form, refer to a dose, amount, or weight percent that would be recognized by one of ordinary skill in the art as providing an equivalent pharmacological effect to that obtained from the specified dose, amount, or weight percent. In some embodiments, the terms "about" and "approximately," as used in this context, contemplate a dose, amount, or weight percent that is within 30%, 20%, 15%, 10%, or 5% of the specified dose, amount, or weight percent.

[0017] As used herein, unless otherwise specified, the terms "about" and "approximately," when used in connection with a numerical value or range of values ​​provided to characterize a particular solid form, such as a particular temperature or temperature range (e.g., those describing melting, dehydration, desolvation, or glass transition temperatures), mass change (e.g., mass change as a function of temperature or humidity), solvent or water content (e.g., mass or percentage), or peak position (e.g., in analysis by IR or Raman spectroscopy or XRPD), indicate that the value or range of values ​​may be deviated from to an extent that would be reasonable to one of ordinary skill in the art while still describing the solid form. Techniques for characterizing crystalline and amorphous forms include, but are not limited to, thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray powder diffractometry (XRPD), single crystal X-ray diffraction, vibrational spectroscopy (e.g., infrared (IR), Raman spectroscopy), solid state and solution nuclear magnetic resonance (NMR) spectroscopy, optical microscopy, hot stage optical microscopy, scanning electron microscopy (SEM), electron crystallography and quantitative analysis, particle size analysis (PSA), surface area analysis, solubility studies, and dissolution studies. In some embodiments, the terms "about" and "approximately," when used in this context, indicate that a numerical value or range of values ​​may vary within 30%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1.5%, 1%, 0.5%, or 0.25% of the recited value or range of values. In the context of molar ratios, "about" and "approximately" indicate that a numerical value or range of values ​​may vary within 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1.5%, 1%, 0.5%, or 0.25% of the recited value or range of values. Because the numerical values ​​of peaks in X-ray powder diffraction patterns can vary from instrument to instrument or sample to sample, quoted numerical values ​​should not be construed as absolute, and it is understood that there is an acceptable variability, such as ±0.2 degrees two-theta (°2θ) or more. For example, in some embodiments, XRPD peak position values ​​can vary by up to ±0.2 degrees 2θ while still describing a particular XRPD peak.

[0018] As used herein, unless otherwise specified, a solid form that is "substantially physically pure" is substantially free of other solid forms. In some embodiments, a substantially physically pure crystalline form contains less than about 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.4%, 0.3%, 0.2%, 0.1%, 0.05%, or 0.01% by weight of one or more other solid forms. Detection of other solid forms can be achieved by any method apparent to one of skill in the art, including, but not limited to, diffraction analysis, thermal analysis, elemental combustion analysis, and / or spectroscopy.

[0019] As used herein, unless otherwise specified, a solid form that is "substantially chemically pure" is substantially free of other chemical compounds (i.e., chemical impurities). In some embodiments, a solid form that is substantially chemically pure contains less than about 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.4%, 0.3%, 0.2%, 0.1%, 0.05%, or 0.01% by weight of one or more other chemical compounds. Detection of other chemical compounds can be achieved by any method apparent to one of skill in the art, including, but not limited to, methods of chemical analysis such as mass spectrometry, spectroscopic analysis, thermal analysis, elemental combustion analysis, and / or chromatographic analysis.

[0020] As used herein, unless otherwise indicated, a chemical compound, solid form, or composition that is "substantially free" of other chemical compounds, solid forms, or compositions means that the compound, solid form, or composition contains, in some embodiments, less than about 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.4%, 0.3%, 0.2%, 0.1%, 0.05%, or 0.01% by weight of other compounds, solid forms, or compositions.

[0021] In any compound described herein having one or more chiral centers, unless the absolute stereochemistry is explicitly indicated, it is understood that each center may independently be in the R or S configuration, or a mixture thereof. Thus, the compounds provided herein may be enantiomerically pure, enantiomerically enriched, racemic, diastereomerically pure, diastereomerically enriched, or a stereoisomeric mixture. Additionally, in any compound described herein having one or more double bonds that produce geometric isomers that can be defined as E or Z, it is understood that each double bond may independently be E or Z, or a mixture thereof. Similarly, it is understood that in any compound described, all tautomeric forms are also intended to be included.

[0022] It is understood that the compounds described herein can be isotopically labeled. Substitution with isotopes such as deuterium can provide certain therapeutic advantages due to greater metabolic stability, such as increased in vivo half-life or reduced dosage requirements. Each chemical element represented in a compound structure may include any isotope of that element. For example, in a compound structure, a hydrogen atom may be explicitly disclosed or understood as being present in the compound. At any position in a compound where a hydrogen atom can be present, the hydrogen atom may be any isotope of hydrogen, including, but not limited to, hydrogen-1 (protium) and hydrogen-2 (deuterium). Thus, reference to a compound herein encompasses all possible isotopic forms unless the context clearly indicates otherwise.

[0023] When a range of values ​​is provided, it is understood that the upper and lower limits, and every intervening value between the upper and lower limits of that range, are encompassed within an embodiment.

[0024] Terms and phrases used in this application, and variations thereof, particularly in the appended claims, should be construed as open-ended rather than limiting, unless expressly stated. As an example above, the term "including" should be construed to mean "including without limitation," "including but not limited to," etc. As used herein, the term "comprising" is synonymous with "including," "containing," or "characterized by" and is inclusive or open-ended, not excluding additional, unrecited elements or method steps. The term "having" should be construed as "having at least." The term "including" should be construed as "including, but not limited to." The term "example" is used to provide illustrative examples rather than an exhaustive or exclusive list of items under discussion. The use of terms such as "preferably," "preferred," "desired," or "desirable," and words of similar import, should not be understood to imply that a particular feature is critical, essential, or even important to its structure or function, but rather is intended merely to highlight alternative or additional features that may or may not be utilized in a particular embodiment. Additionally, the term "comprising" is intended to be synonymous with the phrases "having at least" or "including at least." When used in the context of a process, the term "comprising" means that the process includes at least the recited steps, but may include additional steps. When used in the context of a compound, composition, or device, the term "comprising" means that the compound, composition, or device includes at least the recited features or components, but may also include additional features or components.

[0025] With respect to the use of virtually any plural and / or singular term herein, those skilled in the art can convert from plural to singular and / or from singular to plural as appropriate depending on the context and / or application. Various singular / plural permutations may be expressly stated herein for clarity. The indefinite article "a" or "an" does not exclude a plurality. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage. Any reference signs in the claims should not be construed as limiting the scope thereof.

[0207] One or more free base forms or one or more salt forms of Compound A, or pharmaceutically acceptable salts thereof, which may be used to treat, ameliorate, and / or inhibit the growth of cancers in which inhibition of WEE1 activity is beneficial, are provided in any of the embodiments described in paragraphs

[0069] to

[0076] under the heading "Compound."

[0208] As used herein, "subject" refers to an animal that is the object of treatment, observation, or experiment. "Animal" includes cold-blooded and warm-blooded vertebrates and invertebrates, such as fish, crustaceans, reptiles, and particularly mammals. "Mammals" include, but are not limited to, mice, rats, rabbits, guinea pigs, dogs, cats, sheep, goats, cows, horses, primates, such as monkeys, chimpanzees, and apes, and particularly humans. In some embodiments, the subject may be a human. In some embodiments, the subject may be a child and / or infant, such as a child or infant with a fever. In other embodiments, the subject may be an adult.

[0209] As used herein, the terms "treat," "treating," "treatment," "therapeutic," and "therapy" do not necessarily imply a complete cure or elimination of a disease or condition. Any alleviation, to any extent, of any undesirable signs or symptoms of a disease or condition can be considered treatment and / or therapy. Furthermore, treatment can include actions that may worsen a subject's overall feeling of health or appearance.

[0210] The terms "therapeutically effective amount" and "effective amount" are used to refer to the amount of an active compound or pharmaceutical agent that elicits a described biological or medical response. For example, a therapeutically effective amount of a compound, salt, or composition may be the amount necessary to prevent, alleviate, or ameliorate the symptoms of a disease or condition, or to prolong the survival of the subject being treated. This response may occur in a tissue, system, animal, or human, and includes alleviation of the signs or symptoms of the disease or condition being treated. Determination of an effective amount is well within the capabilities of one of ordinary skill in the art in light of the disclosure provided herein. The therapeutically effective amount of a compound disclosed herein required as a dose will depend on the route of administration, the type of animal, such as a human, being treated, and the physical characteristics of the particular animal under consideration. Dosage can be adjusted to achieve the desired effect and will depend on factors such as body weight, diet, concurrent medications, and other factors that one of ordinary skill in the medical field would recognize.

[0211] For example, an effective amount of a compound or radiation is an amount that results in (a) relief, alleviation, or elimination of one or more symptoms caused by cancer, (b) reduction in tumor size, (c) tumor elimination, and / or (d) long-term disease stabilization (growth arrest) of the tumor. In the treatment of lung cancer (e.g., non-small cell lung cancer), a therapeutically effective amount is an amount that reduces or eliminates cough, shortness of breath, and / or pain. As another example, an effective amount, or therapeutically effective amount, of a WEE1 inhibitor is an amount that results in reduced WEE1 activity and / or phosphorylation (e.g., CDC2 phosphorylation). Reductions in WEE1 activity are known to those skilled in the art and can be determined by analyzing WEE1 endogenous kinase activity and phosphorylation of downstream substrates.

[0212] The amount of Compound A free base or salt form, or its pharmaceutically acceptable salt, required for therapeutic use will vary depending not only on the particular compound or salt selected, but also on the route of administration, the nature and / or symptoms of the disease or condition being treated, and the age and condition of the patient, and will ultimately be at the discretion of the attending physician or clinician. In the case of administration of a pharmaceutically acceptable salt, the dosage may be calculated as the free base. As will be understood by those skilled in the art, in certain circumstances, it may be necessary to administer the compounds disclosed herein in amounts that exceed, or even far exceed, the dosage ranges set forth herein to effectively and aggressively treat, particularly, progressive diseases or conditions.

[0213] Generally, however, suitable doses will often be within the range of about 0.05 mg / kg to about 10 mg / kg. For example, suitable doses may be within the range of about 0.10 mg to about 7.5 mg per kg of body weight per day, e.g., about 0.15 mg to about 5.0 mg per kg of recipient body weight per day, about 0.2 mg to 4.0 mg per kg of recipient body weight per day, or any amount therebetween. The compound may be administered in unit dosage form, which may contain, for example, 1 to 500 mg, 10 to 100 mg, 5 to 50 mg, or any amount therebetween of active ingredient per unit dosage form.

[0214] The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day The sub-dose itself may be further divided, for example, into a number of discrete loosely spaced administrations.

[0215] As will be readily apparent to one skilled in the art, the useful in vivo dosage and the particular method of administration will vary depending on the age, weight, severity of the affliction, mammalian species being treated, the particular compound being used, and the The activity of the compound will vary depending on the specific application for which it is used, and the specific application for which it is used. The determination of effective dosage levels, i.e., the dosage levels necessary to achieve the desired result, can be accomplished by one of ordinary skill in the art using routine methods, for example, human clinical trials, in vivo studies, and in vitro studies. The determination of effective dosage levels, i.e., the dosage levels necessary to achieve the desired result, can be accomplished by one of ordinary skill in the art using routine methods, for example, human clinical trials, in vivo studies, and in vitro studies. For example, useful dosages of the free base form or salt form of Compound A, or a pharmaceutically acceptable salt thereof, can be determined by comparing their in vitro activity and in vivo activity in animal models. Such comparisons can be made by comparison with established drugs, such as cisplatin and / or gemcitabine.

[0216] Dosage amount and interval may be adjusted individually to provide plasma concentrations sufficient to maintain the active moiety's modulatory effect or minimal effective concentration (MEC). The MEC varies for each compound but can be estimated from in vivo and / or in vitro data. The dosage required to achieve the MEC will depend on individual characteristics and the route of administration. However, HPLC assays or bioassays can be used to measure plasma concentrations. Dosage intervals can also be determined using the MEC value. Compositions should be administered using a regimen that maintains plasma concentrations above the MEC for 10-90% of the time, preferably 30-90%, and most preferably 50-90%. In cases of local administration or selective uptake, the effective local concentration of a drug may not be related to plasma concentration.

[0217] It should be noted that the attending physician would know how and when to terminate, interrupt, or adjust administration due to toxicity or organ dysfunction. Conversely, the attending physician would also know to adjust treatment to higher levels if the clinical response is not adequate (precluding toxicity). The magnitude of the dose administered in the management of the disease of interest will vary with the severity of the disease or condition to be treated and the route of administration. The severity of the disease or condition may, for example, be assessed, in part, by standard prognostic evaluation methods. Furthermore, the dose, and perhaps the frequency of administration, will also vary with the age, weight, and response of the individual patient. Programs comparable to those discussed above may be used in veterinary medicine.

[0218] The compounds, salts, and compositions disclosed herein can be evaluated for efficacy and toxicity using known methods. For example, the toxicology of a particular compound or a subset of compounds sharing a particular chemical moiety can be established by evaluating in vitro toxicity on cell lines, such as mammalian cell lines, preferably human cell lines. The results of such studies often predict toxicity in animals, such as mammals, or particularly humans. Alternatively, the toxicity of a particular compound in an animal model, such as a mouse, rat, rabbit, dog, or monkey, can be determined using known methods. The efficacy of a particular compound can be established using several recognized methods, such as in vitro methods, animal models, or human clinical trials. When selecting a model for determining efficacy, those skilled in the art can rely on the state of the art to guide them in selecting the appropriate model, dose, route of administration, and / or regimen.
