Abstract
Description
FUSED TRICYCLIC COMPOUNDS AND METHODS OF USE THEREOFTECHNICAL FIELD
[0001] Disclosed herein are certain novel spiro heterocyclic compounds and analogues and derivatives thereof, as WRN inhibitors that inhibit Werner Syndrome helicase enzyme (WRN) activity, and are therefore useful in treating cancers characterized as microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) . More particularly, this invention is directed to pharmaceutical compositions compromising such compounds and methods for producing such compounds.BACKGROUND
[0002] The ultimate goal of anti-cancer drug development is the discovery of chemicals that can eliminate cancer cells without harming the patient’s normal cells (Kaelin, W.G. Jr. The concept of synthetic lethality in the context of anticancer therapy. Nat. Rev. Cancer 5, 689–698 (2005) ) . The discovery of synthetic lethal interactions with genetic deficiencies in cancers has highlighted several candidate targets for drug development, with variable clinical success. Synthetic lethality (SL) occurs when simultaneous mutations in two genes causes cell death, but a single mutation in either gene is viable (Lucchesi, J.C. Synthetic lethality and semi-lethality among functionally related mutants of Drosophila melanfgaster. Genetics 59, 37–44 (1968) ) . Due to the nature of these interactions, inhibiting the products of genes that have a synthetic lethal relationship with prevalent genetic mutations in cancer cells should specifically kill cancer cells, while sparing normal cells (O’Neil, N.J., Bailey, M.L. & Hieter, P. Synthetic lethality and cancer. Nat. Rev. Genet 18, 613–623 (2017) ) .
[0003] DNA mismatch repair (MMR) is a conserved mechanism that contributes to maintenance of genome stability by removing errors generated during DNA replication, long-tract DNA repair synthesis, and recombination (Pecina-Slaus, N., Kafka, A., Salamon, I. & Bukovac, A. Mismatch Repair Pathway, Genome Stability and Cancer. Front Mol. Biosci. 7, 122 (2020) ) . MMR deficiencies lead to a phenotype known as microsatellite instability (MSI) . As a result, tumors with microsatellite instability high (MSI-H) status carries higher mutational burden, frequent deletion and insertion events in repetitive DNA tracts, and extended TA dinucleotide repeat sequences across the genome (van Wietmarschen N. et al., Nature 586, 292-298 (2020) ) .
[0004] A sizable subset of endometrial, ovarian, colorectal, and gastric cancers is characterized by MSI-H (Kim, T.M.; Laird, P.W.; Park, P.J. The landscape of microsatellite instability in colorectal and endometrial cancer genomes. Cell 155, 858-868 (2013) ; Pal, T.; Permuth-Wey, J.; Kumar, A.; Sellers, T.A. Systematic review and meta-analysis of ovarian cancers: estimation of microsatellite-high frequency and characterization of mismatch repair deficient tumor histology. Clin. Cancer Res. 14, 6847-6854 (2008) ) . While patients with MSI-H cancers generally respond well to immune checkpoint inhibitors (ICIs) with an overall response rate of ~40%, a significant proportion of MSI tumors do not respond, or evolve resistance, to immunotherapy and chemotherapy, highlighting the need for more and improved targeted and combinatorial treatments (Zhao, P.; Li, L.; Jiang, X.; Li, Q. Mismatch repair deficiency / microsatellite instability-high as a predictor for anti-PD-1 / PD-L1 immunotherapy efficacy. J. Hematol. Oncol. 12, 54 (2019) ; Lemery, S.; Keegan, P.; Pazdur, R. First FDA Approval Agnostic of Cancer Site-When a Biomarker Defines the Indication. N. Engl. J. Med. 377, 1409-1412 (2017) ) .
[0005] WRN (WRN RecQ helicase) has been identified by several groups and companies as a synthetic lethal vulnerability in MSI-H cell lines by several large-scale functional genomics screens across large panels of cell lines (Behan, F.M. et al. Prioritization of cancer therapeutic targets using CRISPR-Cas9 screens. Nature 568, 511-516 (2019) ; Chan, E.M. et al. WRN helicase is a synthetic lethal target in microsatellite unstable cancers. Nature 568, 551-556 (2019) ; Kategaya, L. et al. Werner Syndrome Helicase Is Required for the Survival of Cancer Cells with Microsatellite Instability. iScience 13, 488-497 (2019) ) . WRN is a multifunctional enzyme with helicase and exonuclease activities and plays roles in various cellular processes crucial for the maintenance of genome stability, including DNA replication, transcription, DNA repair, and telomere maintenance (Bohr, V.A. Rising from the RecQ-age: the role of human RecQ helicases in genome maintenance. Trends Biochem Sci. 33, 609–620 (2008) ; Singh, D.K., Ahn, B. & Bohr, V.A. Roles of RECQ helicases in recombination-based DNA repair, genomic stability and aging. Biogerontology 10, 235–252 (2009) ) . Its helicase activity has been shown to be crucial to the survival of cell lines with defective mismatch repair that have become MSI-H (Lieb, S. Werner syndrome helicase is a selective vulnerability of microsatellite instability-high tumor cells. eLife 8, e43333 (2019) ) . Together with the observation that WRN knockdown is tolerated in microsatellite stable (MSS) cell lines, these results indicate that WRN helicase inhibitors may provide a new therapeutic option for MSI-H cancers (Kategaya, L.; Perumal, S.K.; Hager, J.H.; Belmont, L.D. Werner Syndrome Helicase Is Required for the Survival of Cancer Cells with Microsatellite Instability. iScience, 13, 488-497 (2019) ) .SUMMARY OF INVENTION

[0268] Definitions
[0269] The following description is made with the understanding that the present disclosure is to be considered as an exemplification of the claimed subject matter, and is not intended to limit the appended claims to the specific embodiments illustrated. The headings used in this disclosure are provided for convenience and are not to be considered to limit the claims in any way. Embodiments illustrated under any heading might be combined with any other illustrated heading embodiments.
[0270] All technical and scientific terms used herein, unless defined otherwise, have the same meaning as commonly understood by one of ordinary skill in the art. It must be noted that as used in this disclosure, the singular forms “a” , “an” , and “the” include plural referents unless the context clearly dictates otherwise. Thus, “the compound” includes a plurality of such compounds and “the assay” includes one or more assays, and so forth.
[0271] As used in the present disclosure, the following words, phrases and symbols are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.
[0272] A dash “-” unless otherwise indicated, as used herein, at the front or end of a chemical group is used, a matter of convenience, to indicate a point of attachment for a substituent. For example, -OH is attached through the carbon atom; chemical groups may be depicted with or without one or more dashes without losing their ordinary meaning. A wavy line drawn through a line in a structure indicates a point of attachment of a group. Unless chemically or structurally required, no directionality is indicated or implied by the order in which a chemical group is written or named. A solid line coming out of the center of a ring indicates that the point of attachment for a substituent on the ring can be at any ring atom.
[0273] The prefix “Cm-n ” unless otherwise indicated, as used herein, indicates that the following group has from m to n carbon atoms. For example, “C1-6 alkyl” indicates that the alkyl group has from 1 to 6 carbon atoms, for example, without limitation, the number of carbon atoms maybe 1, 2, 3, 4, 5, or 6. In similar manner, the term “m-n membered” rings or “m-to n-membered” ring , m and n mean integer ranges of ring atoms from m to n, such as “3-7 membered heterocyclic ring” or “3-to 7-membered heterocyclic ring” , refers to a ring containing 3-7 ring atoms (e.g. 3, 4, 5, 6, or 7 ring atoms) , of which up to 80%may be heteroatoms, such as N, O, or S, and the remaining atoms are carbon.
[0274] “A compound provided herein” or “a compound described herein” or “a compound disclosed herein” or “a compound of the present disclosure” and the like refers to the compounds of Formula (I) or similar compounds represented by other Formulas.
[0275] In certain embodiments, the term “about” , directed to that value or parameter per se, includes the indicated amount ±10%, ±5%, or ±1%. Also, the term “about X” includes description of “X” .
[0276] As used herein, any “R” group (s) such as, without limitation, R1, R2, R3, etc., represent substituents that can be attached to the indicated atom. An “R” group may be substituted or unsubstituted. If two “R” groups are described as being “taken together” , refers to the two “R” groups and the atoms they are attached to can form a ring including but not limited to cycloalkyl, aryl, heteroaryl, heterocyclyl or carbocyclyl. For example, without limitation, if R11 and R12 of NR11R12 group are indicated to be “taken together” , it means that they are covalently bonded to one another to form a ring as follow:
[0277] “Adjoining atoms” as used herein, refers to atoms that are in immediately next to each other. For instance, in “C1-C2-C3-C4” atom C1 is adjoining to atom C2, atom C2 is adjoining to atoms C1 and C3, so on and so forth.
[0278] “Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the said event or circumstance occurs and instances in which it does not. Also, the term “optionally substituted” means that any one or more hydrogen atoms on the designated atom or group may or may not be replaced by a suitable substituent other than hydrogen. the substituent may be either the same or different at every position. Combinations of substituents envisioned by this invention are preferably those that result in the formation of stable or chemically feasible compounds. The term “stable, ” as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and, in certain embodiments, their recovery, purification, and use for one or more of the purposes disclosed herein. the terms “optionally substituted” , “optionally unsubstituted or substituted” , “optional unsubstituted or substituted” , “optionally independently unsubstituted or substituted” , and “unsubstituted or substituted” are used interchangeably. For example, when a group is described as being “unsubstituted or substituted” means the group may be unsubstituted or substituted by one or more the indicated substituents.
[0279] “Substituted” means that one or more hydrogen atoms on the designated atom or group is substituted by one or more substituents other than hydrogen, in the conditions that the designated atom's normal valence is not exceeded. The substituents include, but not limited to, deuterium, halogen, hydroxy, CN, alkyl, haloalkyl, alkenyl, haloalkenyl, alkynyl, haloalkynyl, alkoxy, haloalkoxy, acyl, amino, amido, amidino, aryl, azido, carbamoyl, carboxyl, carboxyl ester, cyano, guanidino, heteroalkyl, heteroaryl, heterocyclyl, hydrazino, iimino, oxo, nitro, alkylsulfenyl, alkylsulfinyl, sulfonic acid, alkylsulfonyl, thiocyanate, thiol, thione, or combinations thereof. Similar indefinite structures can be arrived at by defining substituents with further substituents herein, unless otherwise noted, the maximum number of serial substitutions in compounds described herein is three. For example, serial substitutions of substituted aryl groups with two other substituted aryl groups are limited to ( (substituted aryl) substituted aryl) substituted aryl. Similarly, the above definitions are not intended to include impermissible substitution patterns (e.g., methyl substituted by 5 fluorines or heteroaryl groups having two adjacent oxygen ring atoms) . Such impermissible substitution patterns are well known to the skilled artisan. Whenever used to modify a chemical group, “substituted” may describe other chemical groups defined herein. For example, the term “substituted aryl” includes, but not limited to, “alkylaryl” . Unless specified otherwise, if a group is described as optionally substituted, means that any one or more hydrogen atoms on the designated group may or may not be replaced by a suitable substituent other than hydrogen, also namely, the group can be itself without any substituents, also can be substituted by one or more suitable substituents.
[0280] The term “unsaturated” as used herein, means that a moiety has one or more units of unsaturation.
[0281] The term “partially unsaturated” in the context of rings, unless otherwise defined, refers to a monocyclic ring, or a component ring within a polycyclic (e.g. bicyclic, tricyclic, etc. ) ring system, wherein the component ring contains at least one degree of unsaturation in addition to those provided by the ring itself, but is not aromatic. Examples of partially unsaturated rings include, but are not limited to, 3, 4-dihydro-2H-pyran, 3-pyrroline, 2-thiazoline, etc. Where a partially unsaturated ring is part of a polycyclic ring system, the other component rings in the polycyclic ring system may be saturated, partially unsaturated, or aromatic, but the point of attachment of the polycyclic ring system is on a partially unsaturated component ring. For example, unless otherwise defined, 1, 2, 3, 4-tetrahydroquinoline is a partially unsaturated ring if its point of attachment is through the piperidino ring, e.g.:
[0282] The term “saturated” in the context of rings, unless otherwise defined, refers to a 3-10 membered monocyclic ring, or a 7-14 membered polycyclic (e.g. bicyclic, tricyclic, etc. ) ring system, wherein the monocyclic ring or the component ring that is the point of attachment for the polycyclic ring system contains no additional degrees of unsaturation in addition to that provided by the ring itself. Examples of monocyclic saturated rings include, but are not limited to, azetidine, oxetane, cyclohexane, etc. Where a saturated ring is part of a polycyclic ring system, the other component rings in the polycyclic ring system may be saturated, partially unsaturated, or aromatic, but the point of attachment of the polycyclic ring system is on a saturated component ring. For example, unless otherwise defined, 2-azaspiro [3.4] oct-6-ene is a saturated ring if its point of attachment is through the azetidino ring, e.g.:
[0283] The term “aliphatic” or “aliphatic group” , unless otherwise indicated, as used herein, means a straight-chain (i.e., unbranched) or branched, fully saturated or partially saturated (containing one or more units of unsaturation) hydrocarbon chain, that has a single point of attachment to the rest of the molecule. aliphatic may be a fully saturated or partially saturated (containing one or more units of unsaturation) monocyclic hydrocarbon or also multicyclic hydrocarbon (e.g. bicyclic or tricyclic hydrocarbon) , that has a single point of attachment to the rest of the molecule. Unless otherwise specified, aliphatic groups contain 1-6 aliphatic carbon atoms, and the monocyclic hydrocarbon and multicyclic hydrocarbon are collective as “cycloaliphatic” , “cycloaliphatic ring” , or “cycloaliphatic group” . In some embodiments, aliphatic groups contain 1-5 aliphatic carbon atoms. In other embodiments, aliphatic groups contain 1-4 aliphatic carbon atoms. In still other embodiments, aliphatic groups contain 1-3 aliphatic carbon atoms, and in yet other embodiments, aliphatic groups contain 1-2 aliphatic carbon atoms. In some embodiments, “cycloaliphatic ring” refers to a monocyclic C3-C6 hydrocarbon that is completely saturated or partially saturated that contains one or more units of unsaturation, but which is not aromatic, that has a single point of attachment to the rest of the molecule. In some embodiments, “cycloaliphatic ring” refers to a bicyclic or tricyclic C6-C10 hydrocarbon that is fully saturated or partially saturated that contains one or more units of unsaturation, but which is not aromatic, and that has a single point of attachment to the rest of the molecule. Suitable aliphatic groups include, but are not limited to, linear or branched, substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloakenyl, cycloakynyl groups and hybrids thereof including but not limited to (cycloalkyl) alkyl, (cycloalkenyl) alkyl or (cycloalkyl) alkenyl.

Further, the compositions can be presented as a powder, as granules, as a solution, as a suspension in an aqueous liquid, as a non-aqueous liquid, as an oil-in-water emulsion or as a water-in-oil liquid emulsion. In addition to the common dosage forms set out above, the compound represented by Formula (I) and the other similar Formula, or a pharmaceutically acceptable salt thereof, may also be administered by controlled release means and / or delivery devices. The compositions may be prepared by any of the methods of pharmacy. In general, such methods include a step of bringing into association the active ingredient with the carrier that constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both. The product can then be conveniently shaped into the desired presentation.
[0328] Thus, the pharmaceutical compositions of this invention may include a pharmaceutically acceptable carrier and a compound or a pharmaceutically acceptable salt, of Formula (I) and the other similar Formula. The compounds of Formula (I) and the other similar Formula, or pharmaceutically acceptable salts thereof, can also be included in pharmaceutical compositions in combination with one or more other therapeutically active compounds.
[0329] The pharmaceutical carrier employed can be, for example, a solid, liquid or gas. Examples of solid carriers include lactose, terra alba, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, and stearic acid. Examples of liquid carriers are sugar syrup, peanut oil, olive oil, and water. Examples of gaseous carriers include carbon dioxide and nitrogen. In preparing the compositions for oral dosage form, any convenient pharmaceutical media may be employed. For example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and the like may be used to form oral liquid preparations such as suspensions, elixirs and solutions; while carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents, and the like may be used to form oral solid preparations such as powders, capsules and tablets. Because of their ease of administration, tablets and capsules are the preferred oral dosage units whereby solid pharmaceutical carriers are employed. Optionally, tablets may be coated by standard aqueous or nonaqueous techniques.
[0330] A tablet containing the composition of this invention may be prepared by compression or molding, optionally with one or more accessory ingredients or adjuvants. Compressed tablets may be prepared by compressing, in a suitable machine, the active ingredient in a free-flowing form such as powder or granules, optionally mixed with a binder, lubricant, inert diluent, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine, a mixture of the powdered compound moistened with an inert liquid diluent. Each tablet preferably contains from about 0.05mg to about 5g of the active ingredient and each cachet or capsule preferably containing from about 0.05mg to about 5g of the active ingredient. For example, a formulation intended for the oral administration to humans may contain from about 0.5mg to about 5g of active agent, compounded with an appropriate and convenient amount of carrier material which may vary from about 0.05 to about 95 percent of the total composition. Unit dosage forms will generally contain between from about 0.0lmg to about 2g of the active ingredient, typically 0.01mg, 0.02mg, 1mg, 2mg, 3mg, 4mg, 5mg, 6mg, 7mg, 8mg, 9mg, 10mg, 25mg, 50mg, l00mg, 200mg, 300mg, 400mg, 500mg, 600mg, 800mg or l000mg.
[0331] Pharmaceutical compositions of the present invention suitable for parenteral administration may be prepared as solutions or suspensions of the active compounds in water. A suitable surfactant can be included such as, for example, hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof in oils. Further, a preservative can be included to prevent the detrimental growth of microorganisms.
[0332] Pharmaceutical compositions of the present invention suitable for injectable use include sterile aqueous solutions or dispersions. Furthermore, the compositions can be in the form of sterile powders for the extemporaneous preparation of such sterile injectable solutions or dispersions. In all cases, the final injectable form must be sterile and must be effectively fluid for easy syringability. The pharmaceutical compositions must be stable under the conditions of manufacture and storage; thus, preferably should be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol) , vegetable oils, and suitable mixtures thereof.
[0333] Pharmaceutical compositions of the present invention can be in a form suitable for topical use such as, for example, an aerosol, cream, ointment, lotion, dusting powder or the like. Further, the compositions can be in a form suitable for use in transdermal devices. These formulations may be prepared, utilizing a compound represented by Formula I of this invention or a pharmaceutically acceptable salt thereof, via conventional processing methods. As an example, a cream or ointment is prepared by admixing hydrophilic material and water, together with about 0.05wt%to about 10wt%of the compound, to produce a cream or ointment having a desired consistency.
[0334] Pharmaceutical compositions of this invention can be in a form suitable for rectal administration wherein the carrier is a solid. It is preferable that the mixture forms unit dose suppositories. Suitable carriers include cocoa butter and other materials commonly used in the art. The suppositories may be conveniently formed by first admixing the composition with the softened or melted carrier (s) followed by chilling and shaping in molds.
[0335] In addition to the aforementioned carrier ingredients, the pharmaceutical formulations described above may include, as appropriate, one or more additional carrier ingredients such as diluents, buffers, flavoring agents, binders, surface-active agents, thickeners, lubricants, preservatives (including antioxidants) and the like. Furthermore, other adjuvants can be included to render the formulation isotonic with the blood of the intended recipient. Compositions containing a compound described by Formula I or pharmaceutically acceptable salts thereof, may also be prepared in powder or liquid concentrate form.
[0336] Generally, dosage levels on the order of from about 0.001mg / kg to about 150mg / kg of body weight per day are useful in the treatment of the above-indicated conditions or alternatively about 0.05mg to about 7g per patient per day. For example, cancer, disease and conditions of the immune system, may be effectively treated by the administration of from about 0.001 to 50mg of the compound per kilogram of body weight per day or alternatively about 0.05mg to about 3.5g per patient per day.
[0337] It is understood, however, that the specific dose level for any particular patient will depend upon a variety of factors including the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy.

Animals were housed under Optimized Hygienic Conditions in individual ventilation cages at constant temperature and humidity with 3-5 animals in each cage with food and water at libitum and a 12h: 12h light: dark cycle. Animals were allowed to acclimatize for at least 1 week before being enrolled in the experimental design. The study described here was performed according to the guidelines approved by the Institutional Animal Care and Use Committee (IACUC) of INVIVO Biotechnology Co., Ltd, following the guidance of the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) . Tumors were established by subcutaneous inoculation of human colorectal cancer SW48 cells (1x106 cells / animal in 100 μL in PBS) in the right flank of animal. SW48 cells were obtained from ATCC (Cat. No. 30-2008) . The cells were cultured in RPMl-1640 medium (Viva Cell, C3010-0500) supplemented with 10%FBS (Gibco, Cat. No. 10091-148) , 2 mM L-glutamine, 1 mM sodium pyruvate and 10 mM HEP ES at 37℃ in an atmosphere of 5%CO2 in air. Test compounds were dissolved in DMSO. Final formulation was 5%DMSO, 20%Solutol, 75%of an aqueous 20%w / v solution of 2-hydroxypropyl-beta-cyclodextrin (HPβCD) . Treatment was initiated 7 days post tumor cell inoculation, when the xenografts had reached a mean volume of approximately 168 mm3. The tumor bearing animals were randomized based on tumor volumes into experimental groups with 6 animals per group and treatment was initiated. Compounds were dosed orally (p.o. ) once per day (QD) for 3 weeks. Tumor size, in mm3 was calculated following the formula: (L x W2 x π / 6) ; where W = width and L = length of the tumor. As a measure of efficacy, the %T / C value was calculated at the end of the experiment according to:
[0541] (△tumor volumetreated / △tumor volumecontrol) *100
[0542] Tumor growth inhibition (%TGI) was calculated according to:
[0543] TGI (%) = [1- (Ti-T0) / (Vi-V0) ] *100
[0544] Where △tumor volumes represent the mean tumor volume on the evaluation day minus the mean tumor volume at the start of the experiment. Ti is the average tumor volume of a treatment group on a given day, T0 is the average tumor volume of the treatment group on the beginning of the experiment, Vi is the average tumor volume of the vehicle control group on the same day as Ti, and V0 is the average tumor volume of the vehicle group on the same day as T0.
[0545] The results are shown in FIG 1 and FIG 2.
[0546] Results: The compounds in the present invention exhibit superior tumor inhibitory activity, safety and PK compared to HRO761.
[0547] Under the above experimental conditions, thetumor growth inhibition (TGI) at 3 mg / kg on day 21 exceeds 100%. Ideally, the TGI on day 21 is above 105% (See FIG 1 ) .
[0548] Under the above experimental conditions, the body weight change of the mice treated with 3 mg / kg on day 21 is within ±10%and preferably within ±5% (FIG 2) .
