- An example, without limitation, of a prodrug would be a compound of any of Formula I, which is administered as an ester (the "prodrug” ) to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility, but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial.
- a further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety.
- Compounds of Formula I may contain one or more asymmetric centers and may thus occur as racemates and racemic mixtures, single enantiomers, diastereomeric mixtures and individual diastereomers. The present invention is meant to comprehend all such isomeric forms of the compounds of Formula I.

Description
The present invention relates to heterocyclic compounds as inhibitors of HPK1 that are useful for treatment of HPK1 mediated diseases and conditions such as cancer.
Enhancing anti-tumor immunity is emerging as a new cancer treatment method. The hematopoietic progenitor kinase 1 (HPK1) negatively regulates T cell activation, thus contributing the escape of tumor cells from the immune system. Inhibitors of HPK1 may be useful to enhance T cell activity and restore anti-tumor immunity.

A "prodrug" refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrugs may also have improved solubility in pharmaceutical compositions over the parent drug. An example, without limitation, of a prodrug would be a compound of any of Formula I, which is administered as an ester (the "prodrug" ) to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility, but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. A further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety.
Optical Isomers -Diastereomers -Geometric Isomers –Tautomers:
Compounds of Formula I may contain one or more asymmetric centers and may thus occur as racemates and racemic mixtures, single enantiomers, diastereomeric mixtures and individual diastereomers. The present invention is meant to comprehend all such isomeric forms of the compounds of Formula I.
Some of the compounds described herein contain olefinic double bonds, and unless specified otherwise, are meant to include both E and Z geometric isomers.
Some of the compounds of Formula I may contain one or more than one cyclic ring systems and may thus exist in cis-and trans-isomers. The present invention is meant to include all such cis-and trans-isomers.
Some of the compounds described herein may exist with different points of attachment of hydrogen, referred to as tautomers. Such an example may be a ketone and its enol form known as keto-enol tautomers. The individual tautomers as well as mixture thereof are encompassed with compounds of Formula I.
Compounds of the Formula I may be separated into diastereoisomeric pairs of enantiomers by, for example, fractional crystallization from a suitable solvent, for example MeOH or EtOAc or a mixture thereof. The pair of enantiomers thus obtained may be separated into individual stereoisomers by conventional means, for example by the use of an optically active amine or acid as a resolving agent or on a chiral HPLC column.
Alternatively, any enantiomer of a compound of the general Formula I may be obtained by stereospecific synthesis using optically pure starting materials or reagents of known configuration.
Stable Isotope-Labeled Analogs:
One or more than one of the protons in compounds of Formula I to VII can be replaced with deuterium atom (s) , thus providing deuterated analogs that may have improved pharmacological activities.

Additional excipients, for example sweetening, flavoring and coloring agents, may also be present.
The pharmaceutical compositions of the invention may also be in the form of an oil-in-water emulsions. The oily phase may be a vegetable oil, for example olive oil or arachis oil, or a mineral oil, for example liquid paraffin or mixtures of these. Suitable emulsifying agents may be naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate, and condensation products of the partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavouring agents.
Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents. The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleagenous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1, 3-butane diol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono-or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.
The compounds of the invention can also be administered intranasally or by inhalation, typically in the form of a dry powder (either alone, as a mixture, for example, in a dry blend with lactose, or as a mixed component particle, for example, mixed with phospholipids, such as phosphatidylcholine) from a dry powder inhaler or as an aerosol spray from a pressurized container, pump, spray, atomiser (preferably an I atomiser using electrohydrodynamics to produce a fine mist) , or nebuliser, with or without the use of a suitable propellant, such as 1, 1, 1, 2-tetrafluoroethane or 1, 1, 1, 2, 3, 3, 3-heptafluoropropane. For intranasal use, the powder may comprise a bioadhesive agent, for example, chitosan or cyclodextrin.
The pressurized container, pump, spray, atomizer, or nebulizer contains a solution or suspension of the compound (s) of the invention comprising, for example, ethanol, aqueous ethanol, or a suitable alternative agent for dispersing, solubilizing, or extending release of the active, a propellant (s) as solvent and an optional surfactant, such as sorbitan trioleate, oleic acid, or an oligolactic acid.
Prior to use in a dry powder or suspension formulation, the drug product is micronized to a size suitable for delivery by inhalation (typically less than 5 microns) .
This may be achieved by any appropriate comminuting method, such as spiral jet milling, fluid bed jet milling, supercritical fluid processing to form nanoparticles, high pressure homogenization, or spray drying.
Capsules (made, for example, from gelatin or HPMC) , blisters and cartridges for use in an inhaler or insufflator may be formulated to contain a powder mix of the compound of the invention, a suitable powder base such as lactose or starch and a performance modifier such as l-leucine, mannitol, or magnesium stearate. The lactose may be anhydrous or in the form of the monohydrate, preferably the latter. Other suitable excipients include dextran, glucose, maltose, sorbitol, xylitol, fructose, sucrose and trehalose.
A suitable solution formulation for use in an atomizer using electrohydrodynamics to produce a fine mist may contain from l mg to 20 mg of the compound of the invention per actuation and the actuation volume may vary from 1 L to 100 L. A typical formulation may comprise a compound of Formula (A) propylene glycol, sterile water, ethanol and sodium chloride. Alternative solvents which may be used instead of propylene glycol include glycerol and polyethylene glycol.
Suitable flavors, such as menthol and levomenthol, or sweeteners, such as saccharin or saccharin sodium, may be added to those formulations of the invention intended for inhaled/intranasal administration.
Formulations for inhaled/intranasal administration may be formulated to be immediate and/or modified release using, for example, poly (DL-lactic-coglycolic acid (PGLA) . Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release.
In the case of dry powder inhalers and aerosols, the dosage unit is determined by means of a valve which delivers a metered amount. Units in accordance with the invention are typically arranged to administer a metered dose or "puff" containing from 1 fig to 10 mg of the compound of Formula I. The overall daily dose will typically be in the range 1 lag to 10 mg which may be administered in a single dose or, more usually, as divided doses throughout the day.
Compounds of Formula I may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are cocoa butter and polyethylene glycols.
For topical use, creams, ointments, jellies, solutions or suspensions, etc., containing the compound of Formula I are employed. (For purposes of this application, topical application shall include mouth washes and gargles. )
Dosage levels of the order of from about 0.01 mg to about 140 mg/kg of body weight per day are useful in the treatment of the above-indicated conditions, or alternatively about 0.5 mg to about 7 g per patient per day. For example, a condition may be effectively treated by the administration of from about 0.01 to 50 mg of the compound per kilogram of body weight per day, or alternatively about 0.5 mg to about 3.5 g per patient per day, preferably 2.5 mg to 1 g per patient per day.
The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a formulation intended for the oral administration of humans may contain from 0.5 mg to 5 g of active agent compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Dosage unit forms will generally contain between from about 1 mg to about 500 mg of an active ingredient, typically 25 mg, 50 mg, 100 mg, 200 mg, 300 mg, 400 mg, 500 mg, 600 mg, 800 mg, or 1000 mg.
It will be 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.

Biological Activity Evaluation
HPK1 Biochemical Kinase Assay:
The compounds of the current invention can be tested for their inhibition of HPK1 kinase activity by the biochemical assay described below. HPK1 kinase activity is measured by the ADP-Glo
TM Assay (Promega, Madison, WI) . Recombinant human HPK1 kinase (amino acid 1–346) was expressed by baculovirus in Sf9 insect cells with an N-terminal GST tag. In the wells of 384 plates, 1-2 ng/uL of recombinant GST-HPK1 kinase was incubated with 0.1 ug/uL Myelin Basic Protein (MBP) substrate and 10 uM ATP in the presence of varying concentrations of compounds at room temperature for 60 minutes. Equal volume of the ADP-Glo
TM Reagent was added to the kinase reaction mixture, and the wells were incubated at room temperature for 40 minutes. Equal volume of the Kinase Detection Reagent was added to the above mixture, and the wells were incubated at room temperature for 30 minutes. Luminescence signal was then read by CLARIOstar (BMG Labtech) . The IC
50 value was determined as the concentration for 50%inhibition of HPK1 kinase activity compared to DMSO (A: IC
50 < 0.01 μM; B: IC
50 between 0.01 μM and 0.1μM; C: IC
50 between 0.1 μM and 1.0 μM; D: IC
50 > 1.0 μM) .
Cellular IL-2 Induction Assay:
Jurkat cells (ATCC, USA) were incubated with varying concentrations of test compounds in the presence of CD3/CD28 T-cell activator (STEMCELL #10971) over night. Take the supernatant from compound treated cells and measure IL-2 concentration using IL-2 ELISA assay (BioLegend #431804) . Normalize data to blank treated controls to calculate the fold of IL2 increase at indicted concentration of test compound (labels §, ^, #and *denote the compound concentration being tested as 50, 100, 300 and 500 nM, respectively) .
The results of test examples are shown in Table A.
