Description

[Technical Field]

[0001] This disclosure relates to substituted pyrimidopyrimidine compounds that act as human epidermal growth factor receptor 2 (ErbB2) inhibitors. This disclosure also provides compounds of formula (I) and pharmaceutically acceptable salts thereof, as well as the use of the compounds for the treatment of abnormal cell growth (e.g., cancer) in subjects. [Background technology]

[0002] Human epidermal growth factor receptor 2 (ErbB2) is a member of the epidermal growth factor receptor family that possesses tyrosine kinase activity. ErbB2 plays a crucial role in signaling cascades in biochemical pathways involved in cell growth and differentiation. Amplification and mutations of ErbB2 are known to lead to uncontrolled cell proliferation in cancers (e.g., breast cancer, bladder cancer, colorectal cancer, and lung cancer). Existing therapies (including, but not limited to, monoclonal antibodies, bispecific antibodies, and kinase inhibitors) still present problems of high relapse rates and acquired resistance.

[0003] Current kinase inhibitors may be effective treatments for cancer, but their use may be limited due to insufficient selectivity for ErbB2 compared to EGFR. EGFR-related toxicities (e.g., gastrointestinal effects and rash) may necessitate regimen modifications (e.g., discontinuation or dose reduction), leading to suboptimal target coverage and reduced efficacy.

[0004] Furthermore, ErbB2 exon 20 YVMA insertion is associated with a higher incidence of brain metastases in NSCL cancer patients with ErbB2 mutations. Brain-penetrating ErbB2 inhibitors effective against ErbB2 mutations (e.g., YVMA) may be useful in treating patients with brain metastases.

[0005] There remains a need to identify potent, brain-penetrant, mutant-active ErbB2 inhibitors that spare EGFR for the treatment of patients having cancer or other proliferative diseases or conditions caused by alterations in ErbB2. SUMMARY OF THE INVENTION MEANS FOR SOLVING THE PROBLEM

[0037] A "prodrug" is a compound that, after administration, is metabolized or otherwise chemically converted to its active site. A prodrug may be a derivative of an active compound. A prodrug may be active or inactive before being converted to its active form in vivo.

[0038] The term “treatment” is used herein for example in relation to methods of treating inflammatory or gastrointestinal diseases and generally includes the administration of a compound or composition that reduces the frequency of symptoms of a medical condition (e.g., autoimmune disease, inflammatory disease, gastrointestinal disease) or delays its onset in a subject compared to a subject that has not been administered the compound or composition. This may include regressing, reducing, or preventing symptoms, clinical signs, and the underlying pathology of a condition in a manner that improves or stabilizes the condition of the subject (e.g., regression of symptoms of autoimmune or inflammatory diseases, e.g., improvement of the MAYO score in the treatment of ulcerative colitis).

[0039] The embodiments disclosed herein encompass all pharmaceutically acceptable compounds of the (I)-(IL) compounds that are isotope-labeled by substituting one or more atoms with atoms having different atomic masses or mass numbers. Examples of isotopes that can be incorporated into the disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, chlorine, and iodine (for example, respectively, 2 H, 3 H, 11 C,13 C, 14 C, 13 N, 15 N, 15 O, 17 O, 18 O, 31 P, 32 P, 35 S, 18 F, 36 Cl, 123 I, and 125 I) is one example. These radiolabeled compounds may be useful in determining or measuring the efficacy of a compound by characterizing, for example, the site and mode of action, or the binding affinity to pharmacologically important sites of action. Certain isotope-labeled (I)-(IL) compounds (e.g., those incorporating radioisotopes) are useful in studying the tissue distribution of drugs and / or substrates. Tritium, a radioisotope (i.e., 3 H) and carbon-14 (that is, 14 C) is particularly useful for this purpose, given its ease of implementation and the simplicity of its detection means.

[0040] Heavy isotopes (for example, deuterium, i.e., 2 Substitution with H) may offer certain therapeutic benefits resulting from greater metabolic stability (e.g., extended in vivo half-life or reduced required dosage), and is therefore preferable in certain circumstances.

[0041] Substitution with positron-emitting isotopes such as 11C, 18F, 15O, and 13N may be useful in positron emission tomography (PET) studies to examine substrate receptor occupancy. Isotope-labeled compounds (I) to (IL) can generally be prepared by conventional methods known to those skilled in the art, or by using appropriate isotope-labeling reagents instead of previously used unlabeled reagents, in a manner similar to the preparations and examples described below.

[0042] Embodiments disclosed herein encompass in vivo metabolites of the disclosed compounds. Such products may result, for example, from oxidation, reduction, hydrolysis, amidation, esterification, etc., of the administered compound, primarily by enzymatic processes. Accordingly, this disclosure includes compounds produced by processes comprising administering the disclosed compounds to mammals for a period of time sufficient to produce their metabolites.

[0132] The pharmaceutical composition may optionally also include a solubilizer that assists the solubility of one or more compounds selected from the compounds of formula (I), (IA)-(ID), (IA-1), (IA-2), (IB-1), or (IB-2). The term “solubilizer” generally includes agents that result in the formation of micelle solutions or true solutions of the drug. Certain acceptable nonionic surfactants (e.g., polysorbate 80) are useful as solubilizers, as are ophthalmologically acceptable glycols, polyglycols (e.g., polyethylene glycol 400), and glycol ethers.

[0133] Furthermore, the pharmaceutical composition may optionally contain one or more pH adjusters or buffers (e.g., acids (e.g., acetic acid, boric acid, citric acid, lactic acid, phosphoric acid, and hydrochloric acid); bases (e.g., sodium hydroxide, sodium phosphate, sodium borate, sodium citrate, sodium acetate, sodium lactate, and trishydroxymethylaminomethane); and buffers (e.g., citrate / dextrose, sodium bicarbonate, and ammonium chloride)). Such acids, bases, and buffers are included in amounts necessary to maintain the pH of the composition within an acceptable range.

[0134] The composition may optionally also include one or more pharmaceutically acceptable salts in amounts necessary to bring the osmotic pressure concentration of the composition within an acceptable range. Such pharmaceutically acceptable salts include those having a sodium, potassium, or ammonium cation and an anion of chloride, citric acid, ascorbic acid, boric acid, phosphate, bicarbonate, sulfate, thiosulfate, or bisulfite; preferred pharmaceutically acceptable salts include sodium chloride, potassium chloride, sodium thiosulfate, sodium bisulfite, and ammonium sulfate.

[0135] Other pharmaceutical compositions may optionally include one or more preservatives for inhibiting microbial activity. Suitable preservatives include mercury-containing substances (e.g., merfen and thiomersal); stabilized chlorine dioxide; and quaternary ammonium compounds (e.g., benzalkonium chloride, cetyltrimethylammonium bromide, and cetylpyridinium chloride).

[0136] The composition may contain one or more surfactants to enhance physical stability or for other purposes. Suitable nonionic surfactants include polyoxyethylene fatty acid glycerides and vegetable oils (e.g., polyoxyethylene (60) hydrogenated castor oil); and polyoxyethylene alkyl ethers and alkylphenyl ethers (e.g., octoxynol 10, octoxynol 40).
