With the first generation medicinal chemistry synthesis as a starting point, we describe herein process development of AZD4573, an oncology drug candidate. In addition to improved yields and removal of chromatographic steps, we have addressed other factors such as availability of starting materials as well as safety of the chemistry involved. With several steps involving volatile, reactive, and non-UV active materials, reaction optimization was facilitated by implementing off-line 1H NMR analysis of crude mixtures. Key transformations targeted for process development included a Wolff-Kishner reduction, an iridium-catalyzed borylation, and enzymatic resolution of a racemic amino-ester.

A CDK9 inhibitor having short target engagement would enable a reduction of Mcl-1 activity, resulting in apoptosis in cancer cells dependent on Mcl-1 for survival. We report the optimization of a series of amidopyridines (from compound 2), focusing on properties suitable for achieving short target engagement after intravenous administration. By increasing potency and human metabolic clearance, we identified compound 24, a potent and selective CDK9 inhibitor with suitable predicted human pharmacokinetic properties to deliver transient inhibition of CDK9. Furthermore, the solubility of 24 was considered adequate to allow i.v. formulation at the anticipated effective dose. Short-term treatment with compound 24 led to a rapid dose- and time-dependent decrease of pSer2-RNAP2 and Mcl-1, resulting in cell apoptosis in multiple hematological cancer cell lines. Intermittent dosing of compound 24 demonstrated efficacy in xenograft models derived from multiple hematological tumors. Compound 24 is currently in clinical trials for the treatment of hematological malignancies.

Provided are a series of novel pyridine or pyrimidine derivatives which inhibit CDK9 and may be useful for the treatment of hyperproliferative diseases. In particular the compounds are of use in the treatment of proliferative disease such as cancer including hematological malignancies such as acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia, diffuse large B cell lymphoma, Burkitt's lymphoma, follicular lymphoma and solid tumors such as breast cancer, lung cancer, neuroblastoma and colon cancer.
