R is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heteroaryl, heteroalkyl.

Compounds above may be synthesized according to methods in deLong, MA; Sturdivant, JM; Lichorowic, CL; Kornilov, A. Aryl Cyclopropyl Aminoisoquinolinyl Amide Compounds US Patent Application US2018-0327381 A1 published Nov. 15, 2018, which is incorporated into this application in its entirety.

Compounds may be prepared in racemic form or as individual enantiomers or diastereomers by either stereospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers or diastereomers by standard techniques, such as the formation of stereoisomeric pairs by salt formation with an optically active base, followed by fractional crystallization and regeneration of the free acid. The compounds may also be resolved by formation of stereoisomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column. The enantiomers also may be obtained from kinetic resolution of the racemate of corresponding esters using lipase enzymes.

Except as discussed below for tautomeric forms, specifically excluded from the term “isomers,” as used herein, are structural (or constitutional) isomers (i.e., isomers which differ in the connections between atoms rather than merely by the position of atoms in space). For example, a reference to a methoxy group, —OCH₃, is not to be construed as a reference to its structural isomer, a hydroxymethyl group, —CH₂OH. Similarly, a reference to ortho-chlorophenyl is not to be construed as a reference to its structural isomer, meta-chlorophenyl. However, a reference to a class of structures may well include structurally isomeric forms falling within that class (e.g., C₃-alkyl or propyl includes n-propyl and iso-propyl; C₄-alkyl or butyl includes n-, iso-, sec-, and tert-butyl; methoxyphenyl includes ortho-, meta-, and para-methoxyphenyl).

The above exclusion does not pertain to tautomeric forms, for example, keto-, enol-, and enolate-forms, as in, for example, the following tautomeric pairs: keto/enol, imine/enamine, amide/imino alcohol, amidine/amidine, nitroso/oxime, thioketone/enethiol, N-nitroso/hydroxyazo, and nitro/aci-nitro.

Note that specifically included in the term “isomer” are compounds with one or more isotopic substitutions. For example, H may be in any isotopic form, including ¹H, ²H (D), and ³H (T); C may be in any isotopic form, including ¹²C, ¹³C, and ¹⁴C; O may be in any isotopic form, including ¹⁶O and ¹⁸O; and the like.

Salts

A compound described herein can be in the form of a salt, e.g., a pharmaceutically acceptable salt. The term “pharmaceutically acceptable salt” includes salts of the active compounds that are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. Neutral forms of the compounds may be regenerated by contacting the salt with a base or acid and isolating the parent compound in a conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of this disclosure. Examples of pharmaceutically acceptable salts are discussed in Berge et al, 1977, “Pharmaceutically Acceptable Salts.” J. Pharm. Sci. Vol. 66, pp. 1-19.

For example, if the compound is anionic, or has a functional group which may be anionic (e.g., —COOH may be —COO—), then a salt may be formed with a suitable cation. Examples of suitable inorganic cations include, but are not limited to, alkali metal ions such as Na⁺ and K⁺, alkaline earth cations such as Ca²⁺ and Mg²⁺, and other cations. Examples of suitable organic cations include, but are not limited to, ammonium ion (i.e., NH₄⁺) and substituted ammonium ions (e.g., NH₃R₁⁺, NH₂R₂⁺, NHR₃⁺, NR₄⁺). Examples of some suitable substituted ammonium ions are those derived from: ethylamine, diethylamine, dicyclohexylamine, triethylamine, butylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, benzylamine, phenylbenzylamine, choline, meglumine, and tromethamine, as well as amino acids, such as lysine and arginine.

If the compound is cationic, or has a functional group that may be cationic (e.g., —NH₂may be —NH₃⁺), then a salt may be formed with a suitable anion. Examples of suitable inorganic anions include, but are not limited to, those derived from the following inorganic acids: hydrochloric, hydrobromic, hydroiodic, sulfuric, sulfurous, nitric, nitrous, phosphoric, and phosphorous.

Examples of suitable organic anions include, but are not limited to, those derived from the following organic acids: 2-acetyoxybenzoic, acetic, ascorbic, aspartic, benzoic, camphorsulfonic, cinnamic, citric, edetic, ethanedisulfonic, ethanesulfonic, fumaric, glucoheptonic, gluconic, glutamic, glycolic, hydroxymaleic, hydroxynaphthalene carboxylic, isethionic, lactic, lactobionic, lauric, maleic, malic, methanesulfonic, mucic, oleic, oxalic, palmitic, pamoic, pantothenic, phenylacetic, phenylsulfonic, propionic, pyruvic, salicylic, stearic, succinic, sulfanilic, tartaric, toluenesulfonic, and valeric. Examples of suitable polymeric organic anions include, but are not limited to, those derived from the following polymeric acids: tannic acid, carboxymethyl cellulose.

Unless otherwise specified, a reference to a particular compound also includes salt forms thereof.

Chemically Protected Forms

It may be convenient or desirable to prepare, purify, and/or handle an active compound in a chemically protected form. The term “chemically protected form” is used herein in the conventional chemical sense and pertains to a compound in which one or more reactive functional groups are protected from undesirable chemical reactions under specified conditions (e.g., pH, temperature, radiation, solvent, and the like). In practice, well known chemical methods are employed to reversibly render unreactive a functional group, which otherwise would be reactive, under specified conditions. In a chemically protected form, one or more reactive functional groups are in the form of a protected or protecting group (also known as a masked or masking group or a blocked or blocking group). By protecting a reactive functional group, reactions involving other unprotected reactive functional groups can be performed, without affecting the protected group; the protecting group may be removed, usually in a subsequent step, without substantially affecting the remainder of the molecule. See, for example, Protective Groups in Organic Synthesis (T. Green and P. Wuts; 3rd Edition; John Wiley and Sons, 1999). Unless otherwise specified, a reference to a particular compound also includes chemically protected forms thereof.

A wide variety of such “protecting,” “blocking,” or “masking” methods are widely used and well known in organic synthesis. For example, a compound which has two nonequivalent reactive functional groups, both of which would be reactive under specified conditions, may be derivatized to render one of the functional groups “protected,” and therefore unreactive, under the specified conditions; so protected, the compound may be used as a reactant which has effectively only one reactive functional group. After the desired reaction (involving the other functional group) is complete, the protected group may be “deprotected” to return it to its original functionality.

A hydroxy group may be protected as an ether (—OR) or an ester (—OC(O)R), for example, as: a t-butyl ether; a benzyl, benzhydryl (diphenylmethyl), or trityl (triphenylmethyl) ether; a trimethylsilyl or t-butyldimethylsilyl ether; or an acetyl ester (—OC(O)CH₃, —OAc).

An aldehyde or ketone group may be protected as an acetal (RCH(OR)₂) or ketal (R₂C(OR)₂), respectively, in which the carbonyl group (R₂C═O) is converted to a diether (R₂C(OR)₂), by reaction with, for example, a primary alcohol. The aldehyde or ketone group is readily regenerated by hydrolysis using a large excess of water in the presence of acid.

An amine group may be protected, for example, as an amide (—NRC(O)R) or a urethane (—NRC(O)OR), for example, as: a methyl amide (—NHC(O)CH₃); a benzyloxy amide (—NHC(O)OCH₂C₆H₅, —NH-Cbz); as a t-butoxy amide (—NHC(O)OC(CH₃)₃, —NH-Boc); a 2-biphenyl-2-propoxy amide (—NHCO(O)C(CH₃)₂C₆H₄C₆H₅, —NH-Bpoc), as a 9-fluorenylmethoxy amide (—NH—Fmoc), as a 6-nitroveratryloxy amide (—NH—Nvoc), as a 2-trimethylsilylethyloxy amide (—NH— Teoc), as a 2,2,2-trichloroethyloxy amide (—NH-Troc), as an allyloxy amide (—NH— Alloc), as a 2(-phenylsulphonyl)ethyloxy amide (—NH—Psec); or, in suitable cases (e.g., cyclic amines), as a nitroxide radical (>N-0«).

A carboxylic acid group may be protected as an ester, for example, as: an alkyl ester (e.g., a methyl ester; a t-butyl ester); a haloalkyl ester (e.g., a haloalkyl ester); a trialkylsilylalkyl ester; or an arylalkyl ester (e.g., a benzyl ester; a nitrobenzyl ester); or as an amide, for example, as a methyl amide.

A thiol group may be protected as a thioether (—SR), for example, as: a benzyl thioether; an acetamidomethyl ether (—S—CH₂NHC(O)CH₃)

Prodrugs and Other Modifications

In addition to salt forms, also provided are compounds that are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds described herein. Prodrugs can be converted to the compounds of the present invention by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the compounds of the present invention when placed in a transdermal patch reservoir with or without a suitable enzyme or chemical reagent.

A compound described herein can also be modified by appending appropriate functionalities to enhance selective biological properties. Such modifications are known in the art and include those that increase biological penetration into a given biological system (e.g., blood, lymphatic system, central nervous system), increase oral availability, increase solubility to allow administration by injection, alter metabolism, and/or alter rate of excretion. Examples of these modifications include, but are not limited to, esterification with polyethylene glycols, derivatization with pivalates or fatty acid substituents, conversion to carbamates, hydroxylation of aromatic rings, and heteroatom substitution in aromatic rings.

In addition to a compound of formula (I) or (II) a prostaglandin, and other optional components, the balance of a composition may comprise solvent.

The pH of compositions can affect both stability of the compound and its efficacy. For example, higher pH may result in decomposition of a compound of formula (I), while lower pH may be irritating to the eye. In embodiments, the pH may be about 4.0 to about 7.0, or about 5.0 to about 6.0. In embodiments, a composition may have a pH of at least about 5.0, at least about 5.5, at least about 6.0, at least about 6.5, at least about 7.0, less than about 5.0, less than about 5.5, less than about 6.0, less than about 6.5, less than about 7.0, about 5.0, about 5.1, about 5.2, about 5.3, about 5.4, about 5.5, about 5.6, about 5.7, about 5.8, about 5.9, or about 6.0.

Composition pH can be adjusted with acid or base, if necessary. Any acid or base compatible with the components of the composition can be used. Exemplary acids include hydrochloric acid, citric acid, gluconic acid, lactic acid, acetic acid, and glycolic acid. Exemplary bases include sodium hydroxide, potassium hydroxide, and triethanolamine.

Methods of Making Compositions

Compositions may be prepared using standard methods. In embodiments, composition components may be combined in water (e.g., purified water) with stirring, followed by pH adjustment to a suitable final pH. Techniques for preparing compositions may generally be found in “Remington's Pharmaceutical Sciences”, (Meade Publishing Co., Easton, Pa.).

When preparing compositions, components should be selected to optimize solubility, stability and compatibility. Compositions should typically be sterile and stable under the conditions of manufacture and storage. Compositions may be sterilized by filtering the composition through a sterilizing grade filter, such as a filter with a 0.22 micron nominal pore size.

Methods of Evaluating Compositions

Compositions may be evaluated for stability using established procedures. For example, compositions may be subjected to accelerated stability testing. For example, compositions remain stable, and do not undergo precipitation or become cloudy when they are stored at 40° C. for at least 1 month, 3 months or 6 months prior to evaluation. The active component (e.g., a 6- or 7-aminoisoquinoline compound) should not react with other formulation components, or decompose. Methods of evaluating such compounds include, for example, high performance liquid chromatography (HPLC) or determination of optical rotation (e.g., to determine if a compound has racemized).

Compositions may also be evaluated using the Preservative Effectiveness Test of the United States Pharmacopoeia for parenteral/ophthalmic products. In such tests, which will be known to those skilled in the art, five indicator organisms are utilized for the purpose of challenging the preservative system in a product. Three of the five USP indicator organisms address the growth of bacteria: Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Candida albicans is the representative yeast, while Aspergillus niger is a mold. A product is inoculated (contaminated) with a number of organisms between 1×10⁵(100,000) to 1×10⁶(1,000,000) colony forming units (CFU) per mL of product. At various intervals, depending on the category, the composition is tested to determine its ability to control reproduction or destroy the microorganisms. A logarithmic reduction is evaluated at each test interval required for the category. By test definition, any growth over the allotted amount for any of the indicated microorganisms renders the preservative in the product not effective. Compositions may also be evaluated using the European Pharmacopoeia Preservative Effectiveness Test, which also evaluates growth of P. aeruginosa, S. aureus, C. albicans and A. niger. The compositions of the present disclosure will pass at least one of these preservative effectiveness tests.

Example 4
Exemplary Combination Treatment

Formosan Rock macaque monkeys (Macaca cyclopis), animal identification consisting of uniquely numbered tattoos and color-coded cage cards are used in this study. On Study Day 1, the animals are at least four years old, and weigh at least 4 kg. The ocular tolerability is determined using a paired study design in which composition was administered q.d. AM for three days to one eye of each monkey (n=6 per group) with the untreated contralateral eye serving as an internal control. Each dose was administered just after the t=0, t=24, and t=48 hour measurement of intraocular pressure (IOP). IOP was taken in both eyes at time points of 0, 4, 8, 24, 48, 52, 56, and 72 hours after baseline (t=0) IOP measurement. Mortality observations, clinical observations, ocular irritation, and intraocular pressures were monitored, recorded, or measured throughout the in-life portion of the study. All treatments were administered as eye drops (one drop per eye). Each animal was sedated intramuscularly (IM) with approximately 5 mg/kg ketamine HCl (or to effect) with the objective of using the minimal dose necessary to achieve acceptable sedation to perform the IOP measurement and dosing procedure. A Model 30 CLASSIC pneumotonometer was used to measure intraocular pressure (IOP) non-invasively (Reichert, Inc, Depew, NY). One drop of ocular anaesthetic (0.5% proparacaine) was topically applied to each eye and allowed to take effect for at least 30 seconds prior to each IOP measurement. Using the pneumotonometer manual tonometry mode, and with the animal maintained in an upright position, 3 independent measurements were obtained and averaged for each eye, at all time points.

Three Rho Kinase inhibitor (ROCKi) formulations are prepared using the above Formulation one. When tested according to the above protocol, tolerability is demonstrated.

Example 5
Combination Treatment in Humans
