[0002] Cross-reference to related applications
[0003] This application claims priority to U.S. Provisional Application No. 62 / 733,029, filed on September 18, 2018, U.S. Provisional Application No. 62 / 816,637, filed on March 11, 2019, and U.S. Provisional Application No. 62 / 889,929, filed on August 21, 2019, the disclosure of each of which is incorporated herein by reference in its entirety for all purposes. Technical Field
[0004] Provided herein are compounds, preferably compounds that inhibit the tyrosine kinase activity of a protein selected from Abelson protein (ABL1), Abelson-related protein (ABL2), or chimeric protein BCR-ABL1; compositions thereof, and methods of preparing the same; methods of inhibiting the tyrosine kinase activity of a protein selected from Abelson protein (ABL1), Abelson-related protein (ABL2), or chimeric protein BCR-ABL1; and methods of treating a disease wherein modulation of BCR-ABL1 activity prevents, inhibits, or ameliorates the pathology and / or symptomology of the disease. Background Art
[0005] In chronic myeloid leukemia (CML), the Philadelphia chromosome (Ph) formed by the t(9,22) reciprocal chromosome translocation occurs in hematopoietic stem cells. This chromosome carries the BCR-ABL1 oncogene encoding the chimeric BCR-ABL1 protein. Drugs that inhibit the tyrosine kinase activity of BCR-ABL1 through an ATP competitive mechanism (e.g. (imatinib), (nilotinib) and Dasatinib is an effective treatment for CML; however, some patients relapse due to the emergence of drug-resistant clones. For example, small molecules or combinations thereof can be used to inhibit the activity of BCR-ABL1 and BCR-ABL1 mutations through the ATP binding site, the myristoyl binding site, or a combination of both sites.

[0036] "Prodrug" refers to a compound that is metabolized or otherwise converted into a biologically active or more active compound (or drug) with respect to at least one property after administration. Relative to the drug, the prodrug is chemically modified in a manner that makes it less active or inactive relative to the drug, but the chemical modification allows the corresponding drug to be produced by metabolism or other biological processes after the prodrug is administered. The prodrug may have altered metabolic stability or transport characteristics, fewer side effects or lower toxicity, or an improved flavor relative to the active drug (see, for example, Nogrady, 1985, Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pp. 388-392, which is incorporated herein by reference).
