- Discovery of Janus Kinase 2 (JAK2) and Histone Deacetylase (HDAC) Dual Inhibitors as a Novel Strategy for the Combinational Treatment of Leukemia and Invasive Fungal Infections
-
Clinically, leukemia patients often suffer from the limited efficacy of chemotherapy and high risks of infection by invasive fungal pathogens. Herein, a novel therapeutic strategy was developed in which a small molecule can simultaneously treat leukemia and invasive fungal infections (IFIs). Novel Janus kinase 2 (JAK2) and histone deacetylase (HDAC) dual inhibitors were identified to possess potent anti-proliferative activity toward hematological cell lines and excellent synergistic effects with fluconazole to treat resistant Candida albicans infections. In particular, compound 20a, a highly active and selective JAK2/HDAC6 dual inhibitor, showed excellent in vivo antitumor efficacy in several acute myeloid leukemia (AML) models and synergized with fluconazole for the treatment of resistant C. albicans infections. This study highlights the therapeutic potential of JAK2/HDAC dual inhibitors in treating AML and IFIs and provides an efficient strategy for multitargeting drug discovery.

- New and Practical Synthesis of Momelotinib
-
New and practical synthetic route of momelotinib, a JAK inhibitor, is described on a decagram scale. A convergent synthetic process is adopted to prepare the methyl 4-(2-((4-morpholinophenyl)amino)pyrimidin-4-yl) benzoate intermediate, by cyclization of 1-(4-morpholinophenyl)guanidine and methyl 4-(3-(dimethylamino)acryloyl)benzoate in high yield and mild conditions. Momelotinib is obtained in 43.2% yield over five steps and 99.1% purity (HPLC).

- A novel and efficient synthesis of momelotinib
-
An improved route for the synthesis of momelotinib has been developed. A nucleophilic addition reaction between the starting material, 4-morpholinoaniline, and cyanamide gave the 1-(4-morpholinophenyl)guanidine. Simultaneously, methyl 4-acetylbenzoate was converted into methyl (E)-4-[3-(dimethylamino)acryloyl]benzoate in the presence of N,N-dimethylformamide dimethylacetal. The enaminone intermediate was then condensed at elevated temperature in alcoholic alkali with the 1-(morpholinophenyl)guanidine to form the desired pyrimidine, which was hydrolysed to the corresponding acid. This procedure is simple in operation, without noble metal catalyst and suitable for industrial production. Finally, the desired compound momelotinib was acquired by an amidation reaction.
