BACKGROUND

[003] Janus kinase (JAK) proteins are a family of cytoplasmic protein tyrosine kinases. The four JAKs, JAK1, JAK2, JAK3, and TYK2, and seven signal transducer and activator of transcription (STAT) transcription factors mediate intracellular signal transduction downstream of cytokine receptors, which are implicated in the pathology of autoimmune, allergic, and inflammatory diseases, among others. The JAKs usually associate with cytokine receptors in pairs as either homodimers or heterodimers. Specific cytokines are associated with specific JAK pairings. Each of the four members of the JAK family is implicated in the signaling pathways of at least one of the cytokines associated with inflammation. Binding of a cytokine to a JAK-dependent cytokine receptor induces receptor dimerization which results in phosphorylation of tyrosine residues on the JAK kinase, effecting JAK activation. Phosphorylated JAKs, in turn, bind and phosphorylate various STAT proteins which dimerize, translocate to the cell nucleus, and directly modulate gene transcription, leading, among other effects, to the downstream effects associated with inflammatory or autoimmune disease. Additionally, there is recent evidence that the kinases R.0CK1 and R.0CK2 may interact with the STAT enzymes, resulting in downregulation of IL-21 and IL-17 secretion. Inhibition of ROCK kinases has been noted to have an anti-inflammatory effect as well as the well-known effects of JAK inhibition. In view of the role that kinases play in many disease states, there is an urgent and continuing need for small molecule ligands which inhibit or modulate the activity of kinases. SUMMARY [004] Described herein are compounds, having a formula: or a pharmaceutically acceptable salt thereof. [005] Also described herein are uses of the compounds, including inhibition of kinases and treatment of related diseases. BRIEF DESCRIPTION OF THE DRAWINGS [006] Fig. 1 shows a general scheme for preparing the compounds described herein, where R ¹ , R ² , R ³ , R ⁴ , and R ⁵ are as defined herein. DETAILED DESCRIPTION [007] Described herein are azetidinyl pyrimidine compounds that affect the function of kinases and other proteins, which are useful in treating diseases. Definitions [008] Certain terms, whether used alone or as part of a phrase or another term, are defined below. [009] The articles “a” and “an” refer to one or to more than one of the grammatical object of the article. [0010] Numerical values relating to measurements are subject to measurement errors that place limits on their accuracy. For this reason, all numerical values provided herein, unless otherwise indicated, are to be understood as being modified by the term “about.” Accordingly, the last decimal place of a numerical value provided herein indicates its degree of accuracy.

[0082] The present compounds and associated materials can be finished as a commercial product by the usual steps performed in the present field, for example by appropriate sterilization and packaging steps. For example, the material can be treated by UV/vis irradiation (200-500 nm), for example using photo-initiators with different absorption wavelengths (e.g. Irgacure 184, 2959), preferably water-soluble initiators (e.g. Irgacure 2959). Such irradiation is usually performed for an irradiation time of 1–60 min, but longer irradiation times may be applied, depending on the specific method. The material according to the present disclosure can be finally sterile-wrapped so as to retain sterility until use and packaged (e.g. by the addition of specific product information leaflets) into suitable containers (boxes, etc.). [0083] According to further embodiments, the present compounds can also be provided in kit form combined with other components necessary for administration of the material to the patient. For example, disclosed kits, such as for use in the treatment of cancer, can further comprise, for example, administration materials. [0084] The kits are designed in various forms based on the specific deficiencies they are designed to treat. [0085] The compounds or compositions provided herein may be prepared and placed in a container for storage at ambient or elevated temperature. When the compound or composition is stored in a polyolefin plastic container as compared to a polyvinyl chloride plastic container, discoloration of the compound or composition may be reduced, whether dissolved or suspended in a liquid composition (e.g., an aqueous or organic liquid solution), or as a solid. Without wishing to be bound by theory, the container may reduce exposure of the container’s contents to electromagnetic radiation, whether visible light (e.g., having a wavelength of about 380–780 nm) or ultraviolet (UV) light (e.g., having a wavelength of about 190–320 nm (UV B light) or about 320–380 nm (UV A light)). Some containers also include the capacity to reduce adherence or adsorption of the active agent to the surface of the container. Some containers also include the capacity to reduce exposure of the container’s contents to infrared light, or a second component with such a capacity. The containers that may be used include those made from a polyolefin such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, polymethylpentene, polybutene, or a combination thereof, especially polyethylene, polypropylene, or a combination thereof. In some embodiments, the container is a glass container. The container may further be disposed within a second container, for example, a paper, cardboard, paperboard, metallic film, or foil, or a combination thereof, container to further reduce exposure of the container’s contents to UV, visible, or infrared light. Compounds and compositions benefiting from reduced discoloration, decomposition, or both during storage, include eye drop solutions or implants that include a compound or composition thereof provided herein. The compounds or compositions provided herein may need storage lasting up to, or longer than, three months; in some cases up to, or longer than one year. The containers may be in any form suitable to contain the contents; for example, a bag, a bottle, or a box. [0086] The following examples further illustrate aspects of the present disclosure. However, they are in no way a limitation of the teachings or disclosure as described herein. EXAMPLES Example 1: ROCK and JAK assays. [0087] ROCK Kinase Inhibition Assays. All compounds were initially prepared as 10 mM stocks in anhydrous dimethylsulfoxide (DMSO). A 20 µL aliquot of the 10 mM solutions was transferred to individual wells in column 1 of a 96-well polypropylene microtiter plate (Corning #3363) and diluted with DMSO to give a final compound concentration of 4 mM. Test compounds were then serially diluted 1:5 in DMSO for an 11-point concentration response and further diluted in the assay buffer bringing all compound concentrations to a final range of 100 µM to 10 pM in 2.5% DMSO. The assay was performed in white 96-well, flat-bottom, half-area, non-binding assay plate (Corning #3642) in assay buffer consisting of 20 mM HEPES (pH 7.5), 10 mM MgCl ₂ *6H ₂ O, 100 µM sodium orthovanadate, 0.05% CHAPS and 0.1% bovine serum albumin. A 10 µL aliquot of compound from each well of the intermediate dilution plate and 20 µL of a 2X substrate/enzyme solution containing acceptor substrate (800 nM RSK2 peptide KRRRLSSLRA (SEQ ID NO:1)), ROCK2 enzyme (10 nM), or ROCK1 enzyme, and 1,4-Dithiothreitol (DTT, 2uM) were added to all wells. The reaction was initiated by the addition of 10 µL of 4x stock solution ATP (2 µM). Reactions were thoroughly mixed manually, covered, and allowed to incubate at room temperature for 75 min. Protein kinase activity was quantitated using Promega’s KINASE-GLO(TM) luminescent Kinase Assay Kit according to the manufacturer’s directions. ATP concentrations remaining in Test wells following the termination of the enzymatic reaction were compared against control wells containing equivalent amounts of DMSO containing no inhibitor (CTRL). ATP concentrations in both Test wells and CTRL wells were normalized against background (BKG) ATP concentrations in wells containing concentrations of inhibitor that completely inhibited the protein kinase under investigation (i.e. a concentration that prevented any consumption of ATP over the course of the incubation). Percent of Control (POC) values were determined for each concentration of compound tested according to the equation: POC = ((Test well value – BKG)/ (CTRL – BKG))*100 IC50 values were calculated using the following 4-parameter logistic curve-fitting algorithm: f(x) = (A+((B-A)/(1+((x/C)^D)))) IC50 values were converted to Ki values using the following Cheng-Prusoff Equation: Ki = IC50 / (1 + ([ATP]/Km ATP])). [0088] JAK Kinase Assays. Compounds were prepared in the same manner as described in the ROCK Kinase Assay with the exception to the substrate and enzyme. The JAK 2X substrate/enzyme solution consisted of acceptor substrate (800nM Abl peptide EAIYAAPFAKKK (SEQ ID NO:2)), JAK1, TYK2, JAK2 or JAK3 enzyme (10nM) and DTT (2uM). All other steps and solutions remain identical to the ROCK Kinase Assay above. Example 2.
