Description
Technical Field
The application belongs to the technical field of pharmaceutical chemistry preparation and crystallization. In particular to a salt form and a crystal form of a medicament for diseases or symptoms mediated by S1P1 receptors, and also relates to a preparation method, a pharmaceutical composition and application of the salt form or the crystal form.
Background
1- { 2-fluoro-4- [5- (4-isobutylphenyl) -1,2, 4-oxadiazol-3-yl]-benzyl } -3-azetidinecarboxylic acid of the formula C 23 H 24 FN 3 O 3 Molecular weight 409.45 and chemical structure shown in formula A below.
As used herein, the term "1- { 2-fluoro-4- [5- (4-isobutylphenyl) -1,2, 4-oxadiazol-3-yl ] -benzyl } -3-azetidinecarboxylic acid" is used interchangeably with "the compound of formula A".
The compound shown in the formula A has S1P1 receptor agonist activity and selective specificity, and has remarkably shortened in vivo half-life, so that the compound is a high-quality second-generation S1P1 receptor agonist. Numerous studies have shown that there are a variety of S1P1 receptor agonists that are capable of binding to cognate receptors expressed on lymphocytes and leading to internalization of S1P1 receptors, which in turn prevents lymphocyte export. Therefore, S1P1 receptor agonists can reduce the ability of the body to initiate an immune response by preventing lymphocyte trafficking, and thus can be used as immunosuppressive agents for various autoimmune diseases.
In theory, the compound of formula A may be combined with one or more compounds of formula X m H n Wherein H is a dissociable hydrogen ion, X is a pharmaceutically acceptable anion, and m and n are natural numbers; the compounds of formula a may also be salified with one or more pharmaceutically acceptable cations, such as alkali metal ions or other pharmaceutically acceptable organic cations.
The identification, preparation, composition and use of compounds of formula a are disclosed in patent document CN103450171A, which is incorporated herein by reference. In particular, a method for preparing such a compound is disclosed in example 2. Patent document CN105315266A, which is incorporated by reference into the present application, discloses 12 crystalline forms of the compound of formula a. The inventor researches and discovers that the free bases have extremely low water solubility, the water solubility at 25 ℃ is 1.1 mu g/mL, and the free bases present different stable forms in different solvent environments, such as the most stable crystal form in water is a crystal form I, and the most stable crystal form in an organic solvent is a crystal form IV. The limitations of the compound are therefore: they are both insoluble in water and show polymorphism in the free base form. Therefore, the research on the salt form of the compound shown in the formula A has very important practical significance, and certain undesirable physicochemical or biological pharmaceutical properties of the medicine can be improved by salifying, such as changing the solubility or dissolution rate, polymorphism and the like of the medicine.

unless otherwise noted, "room temperature" means a temperature of about 10 to 30 ℃.
The "cyclic ether" may be tetrahydrofuran, 1, 4-dioxane, etc.

The "removal of solvent" can be carried out by methods conventional in the art, such as filtration, evaporation, centrifugation, nitrogen blowing or spin drying. The "filtration" is generally carried out by suction filtration at room temperature under a pressure less than atmospheric pressure, preferably under a pressure less than 0.09MPa. The "rotary evaporation method" is generally rotary evaporation at a pressure less than atmospheric pressure, preferably at a pressure less than 0.09MPa; the nitrogen blowing is generally to blow nitrogen through a nitrogen blower, and utilize the rapid flow of the nitrogen to volatilize the liquid; the specific operation of the centrifugation is as follows: placing the sample to be separated into a centrifuge tube, for example, centrifuging at 6000 rpm, until all solids settle to the bottom of the centrifuge tube; the specific operation of the volatilization is as follows: the sample solutions were left to evaporate to dryness at different temperatures. The experimental temperature for the "removal of solvent" is preferably 10 to 60 ℃.

The "crystal form" in the invention refers to a unique ordered molecular arrangement or configuration in a crystal lattice, which is proved by the representation of an X-ray powder diffraction pattern of a compound. It is well known to those skilled in the art that experimental errors therein depend on instrument conditions, sample preparation and sample purity. The 2 theta angles of the peaks in the XRD patterns will typically vary slightly from instrument to instrument and sample to sample. The difference in peak angle may vary from sample to sample by 1 °,0.8 °,0.5 °,03 °,0.1 °, etc., depending on the instrument, and typically allows an error of ± 0.2 °, so the difference in peak angle cannot be the only criterion. The relative intensities of the peaks may vary with the sample, sample preparation, and other experimental conditions, so the order of peak intensities cannot be considered the only or determining factor. The influence of experimental factors such as sample height can cause an overall shift in peak angle, and a certain shift is usually allowed.
