Pyrazolopyridine Compounds For IRE1 Inhibition

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 62/811,237, filed February 27, 2019 and U.S. Provisional Patent Application No. 62/813,975, filed March 5, 2019, all of which applications are incorporated herein by reference in their entireties.

BACKGROUND OF THE INVENTION

Cells often experience conditions during which the workload on the endoplasmic reticulum ("ER") protein folding machinery exceeds its capability, causing ER stress. ER stress can result from secretory work overload, expression of folding-defective secretory proteins, deprivation of nutrients or oxygen, changes in luminal calcium concentration, and deviation from resting redox state. Under ER stress, secretory proteins accumulate in unfolded forms within the organelle to trigger a set of intracellular signaling pathways called the Unfolded Protein Response (UPR). UPR signaling increases transcription of genes encoding chaperones, oxidoreductases, lipid-biosynthetic enzymes, and ER-associated degradation (ERAD) components.

In some instances, the ER stressed state remains too great, and cannot be remedied through the UPR’s homeostatic outputs. In these situations, the UPR switches strategies and actively triggers apoptosis. Apoptosis of irremediably stressed cells is a quality control strategy that protects multicellular organisms from exposure to immature and damaged secretory proteins. Many deadly human diseases occur if too many cells die through this process. Conversely, many human diseases such as diabetes mellitus and retinopathies proceed from unchecked cell degeneration under ER stress.

IREla and I RE 1 b are ER-transmembrane proteins that become activated when unfolded proteins accumulate within the organelle. IREla is the more widely expressed family member. The bifunctional kinase/endoribonuclease IREla controls entry into the terminal UPR. IREla senses unfolded proteins through an ER luminal domain that becomes oligomerized during stress.

Under irremediable ER stress, positive feedback signals emanate from the UPR and become integrated and amplified at key nodes to trigger apoptosis. IREla is a key initiator of these pro-apoptotic signals. IREla employs auto-phosphorylation as a timer. Remediable ER stress causes low-level, transient auto-phosphorylation that confines RNase activity to XBP1 mRNA splicing. However, sustained kinase autophosphorylation causes IREla’s RNase to acquire relaxed specificity, causing it to endonucleolytically degrade thousands of ER- localized mRNAs in close proximity to IRE la. These mRNAs encode secretory proteins being co-translationally translocated (e.g., insulin in b cells). As mRNA degradation continues, transcripts encoding ER-resident enzymes also become depleted, thus destabilizing the entire ER protein-folding machinery. Once IREla’s RNase becomes hyperactive, adaptive signaling through XBP1 splicing becomes eclipsed by ER mRNA destruction, which pushes cells into apoptosis.

A terminal UPR signature tightly controlled by IREla’s hyperactive RNase activity causes (1) widespread mRNA degradation at the ER membrane that leads to mitochondrial apoptosis, (2) induction of the pro-oxidant thioredoxin-interacting protein (TXNIP), which activates the NLRP3 inflammasome to produce maturation and secretion of interleukin- 1b, and consequent sterile inflammation in pancreatic islets leading to diabetes, and (3) degradation of pre-miRNA 17, leading to translational upregulation and cleavage of pre- mitochondrial caspase 2 and stabilization of the mRNA encoding TXNIP.

There is a need in the art for novel small molecule compounds that are capable of treating ER stress without resorting to UPR based apoptosis, thereby treating a wide range of disorders and diseases tied to ER stress. Such diseases include, for example,

neurodegenerative diseases, demyelinating diseases, cancers, eye diseases, fibrotic diseases, and/or diabetes. The present invention meets these needs.

Controlled Release Formulations and Drug Delivery Systems

In certain other embodiments, the formulations of the present invention may be, but are not limited to, short-term, rapid-offset, as well as controlled, for example, sustained release, delayed release and pulsatile release formulations.

The term sustained release is used in its conventional sense to refer to a drug formulation that provides for gradual release of a drug over an extended period of time, and that may, although not necessarily, result in substantially constant blood levels of a drug over an extended time period. The period of time may be as long as a month or more and should be a release which is longer that the same amount of agent administered in bolus form. In certain embodiments, the compounds of the invention can be formulated for sustained release over a period of 3-12 months.

For sustained release, the compounds may be formulated with a suitable polymer or hydrophobic material that provides sustained release properties to the compounds. As such, the compounds useful within the methods of the invention may be administered in the form of microparticles, for example by injection, or in the form of wafers or discs by implantation.

In one embodiment of the invention, the compounds of the invention are administered to a patient, alone or in combination with another pharmaceutical agent, using a sustained release formulation.

The term delayed release is used herein in its conventional sense to refer to a drug formulation that provides for an initial release of the drug after some delay following drug administration and that may, although not necessarily, includes a delay of from about 10 minutes up to about 12 hours.

The term pulsatile release is used herein in its conventional sense to refer to a drug formulation that provides release of the drug in such a way as to produce pulsed plasma profiles of the drug after drug administration.

The term immediate release is used in its conventional sense to refer to a drug formulation that provides for release of the drug immediately after drug administration. As used herein, short-term refers to any period of time up to and including about 8 hours, about 7 hours, about 6 hours, about 5 hours, about 4 hours, about 3 hours, about 2 hours, about 1 hour, about 40 minutes, about 20 minutes, about 10 minutes, or about 1 minute and any or all whole or partial increments thereof after drug administration after drug administration.

As used herein, rapid-offset refers to any period of time up to and including about 8 hours, about 7 hours, about 6 hours, about 5 hours, about 4 hours, about 3 hours, about 2 hours, about 1 hour, about 40 minutes, about 20 minutes, about 10 minutes, or about 1 minute and any and all whole or partial increments thereof after drug administration.

Dosing

The therapeutically effective amount or dose of a compound of the present invention depends on the age, sex and weight of the patient, the current medical condition of the patient and the progression of a disease or disorder contemplated in the invention. The skilled artisan is able to determine appropriate dosages depending on these and other factors.

A suitable dose of a compound of the present invention may be in the range of from about 0.01 mg to about 5,000 mg per day, such as from about 0.1 mg to about 1,000 mg, for example, from about 1 mg to about 500 mg, such as about 5 mg to about 250 mg per day. The dose may be administered in a single dosage or in multiple dosages, for example from 1 to 5 or more times per day. When multiple dosages are used, the amount of each dosage may be the same or different. For example, a dose of 1 mg per day may be administered as two 0.5 mg doses, with about a 12-hour interval between doses.

It is understood that the amount of compound dosed per day may be administered, in non-limiting examples, every day, every other day, every 2 days, every 3 days, every 4 days, or every 5 days.

In the case wherein the patient’s status does improve, upon the doctor’s discretion the administration of the inhibitor of the invention is optionally given continuously; alternatively, the dose of drug being administered is temporarily reduced or temporarily suspended for a certain length of time (i.e., a "drug holiday"). The length of the drug holiday optionally varies between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, or 365 days. The dose reduction during a drug holiday includes from 10%-100%, including, by way of example only, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%. Once improvement of the patient’s conditions has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, is reduced, as a function of the disease or disorder, to a level at which the improved disease is retained. In certain other embodiments, patients require intermittent treatment on a long-term basis upon any recurrence of symptoms and/or infection.

The compounds for use in the method of the invention may be formulated in unit dosage form. The term "unit dosage form" refers to physically discrete units suitable as unitary dosage for patients undergoing treatment, with each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, optionally in association with a suitable pharmaceutical carrier. The unit dosage form may be for a single daily dose or one of multiple daily doses (e.g., about 1 to 5 or more times per day). When multiple daily doses are used, the unit dosage form may be the same or different for each dose.

Toxicity and therapeutic efficacy of such therapeutic regimens are optionally determined in cell cultures or experimental animals, including, but not limited to, the determination of the LD ₅₀ (the dose lethal to 50% of the population) and the ED ₅₀ (the dose therapeutically effective in 50% of the population). The dose ratio between the toxic and therapeutic effects is the therapeutic index, which is expressed as the ratio between LD ₅₀ and ED ₅₀ . The data obtained from cell culture assays and animal studies are optionally used in formulating a range of dosage for use in human. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with minimal toxicity. The dosage optionally varies within this range depending upon the dosage form employed and the route of administration utilized.

2-Iodopropane (129 mL, 219.4 g, 1.291 mol) was added dropwise at RT to a mechanically stirred suspension of 3-bromo-4-chloro-li/-pyrazolo[4,3-c]pyridine (CAS: 1246349-99-4) (100 g, 0.43 mol) and anhydrous potassium carbonate (89.2 g, 0.645 mol) in dry DMF (1 L) and the resulting suspension stirred at RT for 16 h. Water (5 L) and EtOAc (2 L) were added with vigorous stirring to give a 2-phase solution. The aqueous layer was separated and further extracted with EtOAc (3 x 1 L) then the combined organic extracts were washed with water (2 x 500 mL), 5 wt% aqueous lithium chloride solution (500 mL), saturated brine (500 mL) then dried (Na2S04) and concentrated in vacuo to give the crude product as an approximately 3: 1 mixture of the 1 -isopropyl and 2-isopropyl alkylation products as a viscous syrup that solidified on standing. The products were separated by column chromatography on S1O2, using a gradient eluent of 0-50% TBME in cyclohexane. The unwanted 3-bromo-4-chloro-2-isopropyl-2//-pyra/olo|4.3-c | pyridine by-product was the first eluting component, which was discarded. Fractions containing the more polar, later eluting component were combined and evaporated to give the title compound (86.3 g, 70%) as a colourless syrup that solidified on standing to a colourless solid. 'H NMR (400 MHz, CDCI ₃ ) d: 8.16 (1H, d, J = 6 Hz), 7.27 (1H, d, J = 6 Hz), 4.77 (1H, septet, J = 6.7 Hz), 1.59 (6H, d, J = 6.7 Hz).

The ammonia solution was charged to a pre-chilled steel pressure vessel containing a suspension of 3-bromo-4-chloro- 1 -isopropyl- 1 //-py ra/olo| 4.3- c] pyridine (intermediate 1) (41.50 g, 0.151 mol) in 2-propanol (200 mL) and the pressure vessel sealed. The vessel was heated to 145°C resulting in a pressure rise to 12.5 bar, and the mixture stirred at this temperature for 48 h then cooled to RT. Remaining excess pressure was released, the vessel unsealed and the resulting suspended white solid collected by filtration. The solid was rinsed with 2-propanol (20 mL) then vacuum dried to give the title compound (24.80 g, 66%) as an off-white solid. ^X H NMR (400 MHz, CDC1 ₃ ) d: 7.81 (1H, d, J = 6.2 Hz),

A NanoLuc luciferase assay (Promega) was used according to the manufacturer’s instructions to detect the luciferase and luminescence measured on a luminometer (EnVision, PerkinElmer). IC50 values calculated by fitting a sigmoidal curve to percent inhibition of control of compound concentration.

Cellular apoptosis assay

INS-1 cells expressing mIREl were grown in RPMI, 10% FCS, 0.0003% b- mercaptoethanol and 150 pg/mL hygromycin B and for assays seeded at 10,000 cells/well in 384 well plates in media without with hygromycin B. After 24 hours incubation test compounds were added to the plate 10-point ½ log dilution series in duplicate and incubated for 30 minutes. Doxy cy cline (final concentration 100 nM) was added and plates incubated for a further 72 hours. To determine the proportion of apoptotic cells Hoechst 33342 (final concentration 10 pg/mL) was added, then after 30 minutes incubation cells imaged and analyzed on an InCell high content imager.
