Description

Macrocyclic KIF18A inhibitors and their use thereof FIELD OF THE INVENTION The present invention relates to organic compounds, in particular to KIF18A (Kinesin Family Member 18A) inhibitors, useful for treatment of cancers in a mammal. In particular, the present invention relates to macrocyclic compounds that have KIF18A inhibition activity, as well as their manufacture, pharmaceutical compositions containing them and their potential use as medicaments. BACKGROUND OF THE INVENTION KIF18A is a mitotic kinesin possessing an ATPase activity. It is thought to regulate dynamics at the plus end of kinetochore microtubules for proper chromosome positioning during cell mitosis (Rath and Kozielsky. Nat. Rev. Cancer.2012, 12(8)). The motor domain of KIF18A mediates the plus-end-directed sliding in an ATP-dependent manner and adopts conformational changes upon ATP hydrolysis. In addition, the accumulation of KIF18A at the plus end of microtubules requires the C-terminal tail domain. Genetic evidence has demonstrated that KIF18A plays dual roles in chromosome alignment and microtubule depolymerization/ stabilization. Depletion of KIF18A leads to aberrant spindles, misaligned chromosomes and activation of spindle assembly checkpoint (SAC). KIF18A depolymerizes longer microtubules more quickly than shorter ones. Genetic ablation of KIF18A results in long microtubules (Mayr et al. Curr. Biol.2007, 17(6)). There is increasing evidence suggesting involvement of KIF18A in cancer progression as the overexpression of KIF18A is often linked with poor prognosis in various tumor types, e.g., liver cancer, colorectal cancer, kidney cancer and pancreatic cancer. Several independent studies have demonstrated that KIF18A is a synthetic lethal partner with different forms of genomic instability, such as whole-genome doubling (WGD), aneuploidy and chromosomal instability (CIN) (Quinton et al. Nature.2021, 590(7846); Cohen-Sharir et al. Nature.2021, 590(7846); Marquis et al. Nat. Commun.2021, 12(1)). Depletion of KIF18A selectively induces mitotic arrest, lagging chromosome, micronuclei formation, cell cycle arrest and apoptosis in CIN-high tumor cells, but marginal effects on diploid cells. Consistently, pharmacological inhibition of KIF18A phenocopies KIF18A loss leading to persistent SAC activation, prolonged mitosis, misaligned chromosomes and apoptosis in WGD+ cancer cells. SUMMARY OF THE INVENTION Objects of the present invention are novel compounds of formula (I), their manufacture, medicaments based on a compound in accordance with the invention and their production as well as the use of compounds of formula (I) as KIF18A inhibitors for the treatment of cancers.

A further embodiment of present invention is (xxi) a compound or a pharmaceutically acceptable salt thereof according to any one of embodiments (i) to (xix), when manufactured according to the process of embodiment (xx). PHARMACEUTICAL COMPOSITIONS AND ADMINISTRATION Another embodiment provides pharmaceutical compositions or medicaments containing the compounds of the invention and a therapeutically inert carrier, diluent or excipient, as well as methods of using the compounds of the invention to prepare such compositions and medicaments. In one example, compounds of formula (I) may be formulated by mixing at ambient temperature at the appropriate pH, and at the desired degree of purity, with physiologically acceptable carriers, i.e., carriers that are non-toxic to recipients at the dosages and concentrations employed into a galenical administration form. The pH of the formulation depends mainly on the particular use and the concentration of compound, but preferably ranges anywhere from about 3 to about 8. In one example, a compound of formula (I) is formulated in an acetate buffer, at pH 5. In another embodiment, the compounds of formula (I) are sterile. The compound may be stored, for example, as a solid or amorphous composition, as a lyophilized formulation or as an aqueous solution. Compositions are formulated, dosed, and administered in a fashion consistent with good medical practice. Factors for consideration in this context include the particular disorder being treated, the particular mammal being treated, the clinical condition of the individual patient, the cause of the disorder, the site of delivery of the agent, the method of administration, the scheduling of administration, and other factors known to medical practitioners. The “effective amount” of the compound to be administered will be governed by such considerations, and is the minimum amount necessary to inhibit KIF18A. For example, such amount may be below the amount that is toxic to normal cells, or the mammal as a whole. In one example, the pharmaceutically effective amount of the compound of the invention administered parenterally per dose will be in the range of about 0.01 to 100mg/kg, alternatively about 0.1 to 20 mg/kg of patient body weight per day, with the typical initial range of compound used being 0.3 to 15 mg/kg/day. In another embodiment, oral unit dosage forms, such as tablets and capsules, preferably contain from about 1 to about 100 (e.g., 25 to 100) mg of the compound of the invention. The compounds of the invention may be administered by any suitable means, including oral, topical (including buccal and sublingual), rectal, vaginal, transdermal, parenteral, subcutaneous, intraperitoneal, intrapulmonary, intradermal, intrathecal and epidural and intranasal, and, if desired for local treatment, intralesional administration. Parenteral infusions include intramuscular, intravenous, intraarterial, intraperitoneal, or subcutaneous administration. The compounds of the present invention may be administered in any convenient administrative form, e.g., tablets, powders, capsules, solutions, dispersions, suspensions, syrups, sprays, suppositories, gels, emulsions, patches, etc. Such compositions may contain components conventional in pharmaceutical preparations, e.g., diluents, carriers, pH modifiers, sweeteners, bulking agents, and further active agents. A typical formulation is prepared by mixing a compound of the present invention and a carrier or excipient. Suitable carriers and excipients are well known to those skilled in the art and are described in detail in, e.g., Ansel, Howard C., et al., Ansel’s Pharmaceutical Dosage Forms and Drug Delivery Systems. Philadelphia: Lippincott, Williams & Wilkins, 2004; Gennaro, Alfonso R., et al. Remington: The Science and Practice of Pharmacy. Philadelphia: Lippincott, Williams & Wilkins, 2000; and Rowe, Raymond C. Handbook of Pharmaceutical Excipients. Chicago, Pharmaceutical Press, 2005. The formulations may also include one or more buffers, stabilizing agents, surfactants, wetting agents, lubricating agents, emulsifiers, suspending agents, preservatives, antioxidants, opaquing agents, glidants, processing aids, colorants, sweeteners, perfuming agents, flavoring agents, diluents and other known additives to provide an elegant presentation of the drug (i.e., a compound of the present invention or pharmaceutical composition thereof) or aid in the manufacturing of the pharmaceutical product (i.e., medicament). An example of a suitable oral dosage form is a tablet containing about 1 to 1000 mg (e.g., 25mg, 50mg, 100mg, 250mg, or 500mg) of the compound of the invention compounded with about 1 to 1000 (e.g., 90-30) mg anhydrous lactose, about 1 to 1000 (e.g., 5-40) mg sodium croscarmellose, about 1 to 1000 (e.g., 5-30) mg polyvinylpyrrolidone (PVP) K30, and about 1 to 1000 (e.g., 1-10) mg magnesium stearate. The powdered ingredients are first mixed together and then mixed with a solution of the PVP. The resulting composition can be dried, granulated, mixed with the magnesium stearate and compressed to tablet form using conventional equipment. An example of an aerosol formulation can be prepared by dissolving the compound of the invention, for example 1 to 1000 (e.g., 5-400 mg), in a suitable buffer solution, e.g. a phosphate buffer, adding a tonicifier, e.g. a salt such sodium chloride, if desired. The solution may be filtered, e.g., using a 0.2 micron filter, to remove impurities and contaminants. An embodiment, therefore, includes a pharmaceutical composition comprising a compound of formula (I), or a stereoisomer or pharmaceutically acceptable salt thereof. In a further embodiment includes a pharmaceutical composition comprising a compound of formula (I), or a stereoisomer or pharmaceutically acceptable salt thereof, together with a pharmaceutically acceptable carrier or excipient. Another embodiment includes a pharmaceutical composition comprising a compound of formula (I) for use in the treatment of cancer.

BIOLOGICAL EXAMPLES Example B1 Kif18A motor assay The motor activity of KIF18A was studied using an ADP-Glo assay (promega). This assay determined the potency of compounds in inhibiting KIF18A ATPase in the presence of microtubules (MT). Recombinant human KIF18A (1-355) protein was expressed in E. coli with an N-terminal GST tag. The protein was purified sequentially on a GST Bestarose FF column, a Mono S 10/100 GL column and a Superdex200 gel filtration column. The entire assay was conducted at RT. KIF18A at a concentration of 8nM was pre- incubated with a three-fold dilution of the test compound or DMSO for 15 minutes in an assay buffer consisting of 15mM Tris pH 7.5, 10mM MgCl2, 0.01% Pluronic F-68, 1μM Taxol, and 50μg/ml microtubules (MT).52μM ATP was added to initiate the enzymatic reaction. At 30 minutes, the ADP-Glo reagent was added to terminate the reaction. Following a 40-minute incubation, the detection reagent (Promega#V913A) was added, and luminescence was measured using a PHERAstar FSX reader (BMG). The percentage of inhibition was calculated using the following formula: % Inhibition = 100 - (Signal compound- Signal positive control) / (Signal vehicle control - Signal positive control) × 100. The positive control represented the group without KIF18A, while the vehicle control was the DMSO group. To determine the effect-dose curve and IC50, a 4-parameter nonlinear regression equation with a variable slope was used, and the analysis was performed using GraphPad Prism 9.0. Table 1: The activities of the compounds of the present invention in Kif18A motor assay Example B2 The anti-proliferation activity of KIF18A was studied using a Cell Titer Glo assay (promega). This assay determined the potency of compounds in inhibiting cell growth. Cell lines were seeded as follows 24 hours before compound treatment: HT-29 (ATCC) 1800 cells/well, 90µl of McCoy’s 5A media supplemented with 10% FBS. Test compounds were added to cells in a 10x dilution scheme by adding 10 µl of serially diluted compound to the plate, and the treated cells were incubated in a 37°C, 5% CO2 incubator. After 3 days incubation, the media and compounds were refreshed with 90 µl media and 10 µl 10x compounds accordingly, and the treated cells were incubated for additional 3 days in a 37°C, 5% CO2 incubator. The cells were treated for 6 days in total, and cell viability determined via the Promega Cell Titre-Glo® Assay kit. Luminescence units were used to calculate %Inhibition. %Inhibition was calculated for each well as: ([max - min] - [test - min]/[max – min]. EC50 values were calculated from concentration vs. %Inhibition data via a four-parameter variable slope model.
