Dapolsertib is an investigational new drug that is being evaluated for the treatment of cancer. It is dual inhibitor of PIM family of serine/threonine protein kinases and mutant forms of FMS-related tyrosine kinase 3 (FLT3) that is being developed by Ryvu Therapeutics SA.[1]
Dapolsertib is an orally available inhibitor of PIM family serine/threonine protein kinases and mutant forms of FMS-related tyrosine kinase 3 (FLT3; STK1) with potential antineoplastic activity. Upon oral administration, dapolsertib binds to and inhibits the kinase activities of PIM-1, -2 and -3, and mutant forms of FLT3, which may result in the interruption of the G1/S phase cell cycle transition, an inhibition of cell proliferation, and an induction of apoptosis in tumor cells that overexpress PIMs or express mutant forms of FLT3. FLT3, a tyrosine kinase receptor that is overexpressed or mutated in various cancers, plays a role in signaling pathways that regulate hematopoietic progenitor cell proliferation, and in leukemic cell proliferation and survival. PIM kinases, downstream effectors of many cytokine and growth factor signaling pathways, including the FLT3 signaling pathway, play key roles in cell cycle progression and apoptosis inhibition and may be overexpressed in various malignancies.

5,6-dibromo-4-nitro-2-(piperidin-4-yl)-1-(propan-2-yl)-1H-1,3-benzodiazole (Example 26A):
4,5-dibromo-1-N-(propan-2-yl)benzene-1,2-diamine (2,8g, 9,lmmol) and
isonipeconic acid (1,17g, 9,lmmol) were taken up in phosphoric acid (17,82g, 0,18mol). The resulting mixture was stirred at 180°C for 3,5 hours. The mixture was allowed to cool to RT and diluted with water to 200ml. The solution was basified to pH 14.0 using solid NaOH. The resulting precipitate was then filtered off and washed repeatedly with MeOH. The filtrate was concentrated in-vacuo. The product was purified on Al2O3 (basic) using DCM/MeOH/NH3 sat. in MEOH (25: 15: 1). The obtained product (8,7mmol, 3,9g) was dissolved in cone. H2SO4 (30ml). Next KNO3 (8,7mmol, 0,89g) was added in one portion at 0° C. The resulting mixture was stirred at 0°C for 3h and at RT overnight. Then the mixture was poured onto ice. The product was filtered and washed with water.The product was purified on on Al2O3 (basic) using DCM/MeOH/NH3 sat. in MEOH (25: 15: 1) to afford 5,6-dibromo-4- nitro-2-(piperidin-4-yl)-1-(propan-2-yl)-1H-1,3-benzodiazole (1,9g). 1H NMR (600 MHz, DMSO) δ 8.74 (bs, 1H), 8.48 (s, 1H), 8.35 (bs, 1H), 4.94 (hept, J = 6.8 Hz, 1H), 3.52 – 3.46 (m, 1H), 3.42 – 3.37 (m, 2H), 3.08 (bs, 2H), 2.07 – 1.96 (m, 4H), 1.60 (d, J = 6.9 Hz, 6H). m/z 446,8; rt 2,7min.
