[0406] Step 1: N-(3-(N-(tert-butyl)sulfamoyl)phenyl)-3,5-dichloropyrazine-2-carboxamide (3.71g, 9.20mmol, intermediate 10), A mixture of DIPEA (2.12 mL, 11.96 mmol) and 2-amino-2-methyl-1-propanol (0.97 mL, 10.12 mmol) in ACN:DMSO (4:1, 50 mL) was stirred at RT for 16 h. Then, water was added and extracted with DCM (2x20 mL). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated under vacuum. The crude product was purified by silica gel chromatography (0-30% EtOAc / EtOH (3:1) in heptane) to give N-(3-(N-(tert-butyl)sulfamoyl)phenyl) -5-Chloro-3-((1-hydroxy-2-methylpropan-2-yl)amino)pyrazine-2-carboxamide (1.50 g, 3.29 mmol, 36% yield). 1 H NMR (DMSO-d 6 )δ:10.85(s,1H),9.03(s,1H),8.44(s,1H),7.87-7.94(m,2H),7.50-7.61(m,3H),5.05(t,J=5.5Hz , 1H), 3.53 (d, J=5.5Hz, 2H), 1.39 (s, 6...

[0417] Step 1: Add 5-(4,4-dimethyl-2-oxooxazolidin-3-yl)-3-(6-azaspiro[2.5]oct-6 to a 50-mL round bottom flask -yl)pyrazine-2-carboxylic acid (111 mg, 0.320 mmol, Intermediate 8) and DCM (4 mL). Then oxalyl chloride (0.24 mL, 0.48 mmol, 2M in DCM) was added, followed by two drops of DMF. The reaction mixture was stirred at RT for 30 min and the solvent was removed under vacuum. The residue was redissolved in DCM (4 mL) and washed with 3-amino-N-(tert-butyl)-5-methylbenzenesulfonamide (78 mg, 0.32 mmol, Intermediate 1) and DIPEA (0.17 mL, 0.96 mmol )deal with. The reaction mixture was stirred at RT for 18 h and the solvent was removed under vacuum. The crude material was absorbed onto a plug of silica gel and purified by chromatography through a silica gel column (eluting with a gradient of 0%-50% EtOA...

Abstract

Provided are compounds of formula (I) as defined herein, and synthetic intermediates thereof, which are capable of modulating the KIF18A protein, thereby affecting the cell cycle and cell proliferation processes to treat cancer and cancer-related diseases. The invention also includes pharmaceutical compositions comprising the compounds and methods for treating conditions associated with KIF18A activity.

Description

[0001] The present invention relates to the field of pharmaceutical agents, and more particularly, to compounds and compositions for modulating KIF18A and uses and methods for managing cell proliferation and treating cancer. Background technique [0002] Cancer is one of the most prevalent diseases that afflict mankind and is the leading cause of death worldwide. In the effort to find an effective treatment or cure for one or more of many different cancers, many groups have devoted considerable time, energy and financial resources over the past few decades. However, of the available cancer treatments and therapies to date, only a few offer a significant degree of success. [0003] Cancer is often characterized by unregulated cell proliferation. Disruption of one or more genes responsible for cellular pathways that control the progression of proliferation through the cell cycle and centrosomal cycling can result in a loss of normal regulation of cell proliferation. These dysr...
