Description

This application claims priority from chinese patent application 201811186743.7 filed as 2018/10/12. The present application refers to the above-mentioned chinese patent application in its entirety.
Technical Field
The present disclosure provides a crystalline form III of (1S,4S) -4-ethoxy-N- (2- ((R) -9- (pyridin-2-yl) -6-oxaspiro [4.5] decan-9-yl) ethyl) -1,2,3, 4-tetrahydronaphthalen-1-amine fumarate and methods of preparation, use of the crystalline form III in pharmaceutical compositions and use of the crystalline form III, compositions in the preparation of a medicament for the treatment and/or prevention of a disease associated with an opioid receptor (MOR) agonist.
Background
Opioid receptors are important G Protein Coupled Receptors (GPCRs), are target points for combination of endogenous opioid peptides and opioid drugs, have a regulating effect on nervous system immunity and endocrine system after being activated, and are the strongest and commonly used central analgesics at present. Endogenous opioid peptides are opioid active substances naturally produced in mammals, and currently known endogenous opioid peptides are roughly classified into enkephalins, endorphins, dynorphins and neokephalins (Pharmacol Rev 2007; 59: 88-123). The central nervous system has its corresponding opioid receptors, i.e., μ (MOR), δ (DOR), κ (KOR), etc. MOR is the target of action of opioid analgesics such as endogenous enkephalin and morphine.
Opioid drugs, when used for a long period of time, produce tolerance and side effects such as respiratory depression and constipation, which have been shown to be closely related to the function of β -arrestin. In order to reduce the side effect of opioid drugs, a drug can be designed based on negative beta-arrestin preferential ligands of MOR, so that the beta-arrestin mediated side effect is reduced, and the therapeutic effect is enhanced, in the research of the oxaspiro derivative as MOR selective drug, TrevenaInc research finds that the activity is poor when the aryl benzyl position is substituted (j.med.chem.2013, 56, 8019-one 8031), but WO2017063509 finds that an MOR compound which shows high activity, remarkably improved Emax and obviously improved hERG after the aryl benzyl position is cyclized and has a single configuration, and the structure is shown as formula (II):

the crystal structure of the compound used as a medicinal active ingredient often affects the chemical and physical stability of the medicament, and the difference of crystallization conditions and storage conditions can cause the change of the crystal structure of the compound and is sometimes accompanied by the generation of other forms of crystal forms. Generally speaking, amorphous drug products do not have regular crystal structures and often have other defects, such as poor product stability, difficult filtration, easy caking, poor flowability, and the like. Therefore, it is necessary to improve various properties of the compound represented by the formula (II).
