[0035] In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the invention. However, those skilled in the art will understand that the invention can be practiced without these details. The following description of several embodiments is given under the understanding that this disclosure is to be considered as examples of the claimed subject matter and is not intended to limit the appended claims to the specific embodiments shown. Headings used throughout this disclosure are provided for convenience only and should not be construed as limiting the claims in any way. Embodiments shown under any heading may be combined with embodiments shown under any other heading.

[0036] definition Unless the context otherwise requires, throughout the specification and claims, the word “comprising” and its variations, such as “including” and “containing”, shall be interpreted in an open, inclusive sense, meaning “including but not limited to”.

[0037] Throughout this specification, the reference to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with that embodiment is included in at least one embodiment of the invention. Therefore, the phrases "in one embodiment" or "in an embodiment" appearing in various places throughout this specification do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0038] Embodiments of the "compound" as used throughout this specification include the solid, crystalline, salt, and eutectic forms of tenofovir alafenamide disclosed herein.

[0039] The phrase "compound" or "compound described herein" refers to salts and / or cocrystals of tenofovir alafenamide. Therefore, "salts and / or cocrystals of tenofovir alafenamide" includes tenofovir alafenamide hemi-dihydroxynaphthyl salt form I, tenofovir alafenamide hemi-dihydroxynaphthyl salt form II, tenofovir alafenamide sebacic acid salt form I, tenofovir alafenamide naphthalene sulfonate form I, tenofovir alafenamide orotate form I, tenofovir alafenamide orotate form II, and tenofovir alafenamide form III.

[0040] In addition, “salts and / or cocrystals of tenofovir alafenamide” include tenofovir alafenamide vanillate and tenofovir alafenamide disennarate.

[0041] The invention disclosed herein is also intended to include all pharmaceutically acceptable salts and / or cocrystals of tenofovir alafenamide that are isotopically labeled by substituting one or more atoms with atoms having different atomic masses or mass numbers. Examples of isotopes that may be incorporated into the disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, chlorine, and iodine, respectively, for example... 2 H, 3 H, 11 C 13 C 14 C 13 N、 15 N、 15 O、 17 O、 18 O、 31 P, 32 P, 35 S, 18 F, 36 Cl、 123 I and 125 I. These radiolabeled compounds can be used to help determine or measure the effectiveness of compounds, for example, by characterizing the site or mode of action, or binding affinity to pharmacologically important sites of action. Certain isotope-labeled salts and / or cocrystals of tenofovir alafenamide, such as those incorporating radioisotopes, can be used in drug and / or substrate tissue distribution studies. Given their ease of incorporation and readily available detection methods, radioisotope tritium (i.e., 3 H) and carbon-14 (i.e. 14 C) Particularly suitable for this purpose.

[0042] Using heavier isotopes such as deuterium (i.e., 2 H) substitution can provide certain therapeutic advantages due to increased metabolic stability. For example, the in vivo half-life may increase or the dosage requirement may decrease. Therefore, in some cases, heavier isotopes may be preferred.

[0043] Using positron emission of isotopes (e.g.) 11 C 18 F, 15 O and 13 N) substitution can be used in positron emission tomography (PET) studies to examine substrate acceptor occupancy. The preparation of isotopically labeled salts and / or cocrystals of tenofovir alafenamide can generally be performed using conventional techniques known to those skilled in the art or by methods similar to those described in the examples below, using appropriate isotopically labeled reagents instead of previously used unlabeled reagents.

[0059] Crystalline forms of tenofovir alafenamide salts and / or eutectic forms It is desired to develop crystalline forms of tenofovir alafenamide salts and / or cocrystals that can be used in the synthesis of tenofovir alafenamide salts and / or cocrystals. These crystalline forms can serve as intermediates in the synthesis of tenofovir alafenamide salts and / or cocrystals. Under certain conditions, the crystalline forms may possess properties suitable for medical or pharmaceutical applications, such as bioavailability, stability, purity, and / or manufacturability.

[0060] Crystalline forms of tenofovir alafenamide salts and / or cocrystals, including substantially pure forms, offer advantages in bioavailability and stability, making them suitable for use as active ingredients in pharmaceutical compositions. Variations in the crystal structure of a pharmaceutical substance or active ingredient can affect the dissolution rate (which may affect bioavailability, etc.), manufacturability (e.g., ease of handling, ability to consistently prepare doses of known strength), and stability (e.g., thermal stability, shelf life, etc.). Such variations can affect the preparation or formulation of pharmaceutical compositions in different dosage or delivery forms (e.g., solutions or solid oral dosage forms, including tablets and capsules). Crystalline forms offer desired or appropriate hygroscopicity, particle size control, dissolution rate, solubility, purity, physical and chemical stability, manufacturability, yield, and / or process control compared to other forms such as non-crystalline or amorphous forms. Therefore, the crystalline forms of salts and / or cocrystals of tenofovir alafenamide can provide advantages such as improvements in the following: the method of preparation of the compound, the stability or storability of the compound in the form of a pharmaceutical product, the stability or storability of the pharmaceutical substance of the compound, and / or the bioavailability and / or stability of the compound as an active agent.

[0260] XRPD data In some embodiments, the crystalline form is characterized by the intergranular plane spacing determined by X-ray powder diffraction (XRPD). XRPD diffraction patterns are typically represented by plotting the peak intensities versus their positions, i.e., diffraction angles 2θ (2-θ) in degrees. Characteristic peaks of a given XRPD can be selected based on their positions and relative intensities to conveniently distinguish the crystal structure from other crystal structures.

[0261] Under the following experimental settings, XRPD patterns were collected on a PANanalytical XPERT-PRO diffractometer: 45 kV, 40 mA, Kα1 = 1.5406 Å, scan range 2 to 40°, step size 0.0084 or 0.0167°, measurement time: 5 minutes.

[0262] Those skilled in the art will recognize that measurements of XRPD peak positions and / or intensities for a given crystalline form of the same compound will vary within an error range. Values ​​in 2θ degrees allow for an appropriate error range. Typically, the error range is expressed in "±". For example, a 2θ degree of approximately "8.7 ± 0.3" represents a range from approximately 8.7 ± 0.3 (i.e., approximately 9.0) to approximately 8.7 ± 0.3 (i.e., approximately 8.4). Depending on sample preparation techniques, calibration techniques applied to the instrument, variations in human operation, etc., those skilled in the art will recognize that an appropriate error range for XRPD can be ±0.5; ±0.4; ±0.3; ±0.2; ±0.1; ±0.05; or smaller. In some embodiments of the invention, the XRPD error range is ±0.05. In some embodiments of the invention, the XRPD error range is ±0.1. In some embodiments of the invention, the XRPD error range is ±0.2. In some embodiments of the invention, the XRPD error range is ±0.5.
