Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of medicine, and relates to a polymorph of a benzo[c]chromane compound and a preparation method and use thereof. BACKGROUND

[0002] Cathepsins are a class of proteolytic enzymes that are widely present in the lysosomes of various tissue cells. According to their structure and catalytic type, cathepsins are divided into three categories: serine proteases (cathepsins A and G), aspartic proteases (cathepsins D and E), and cysteine proteases 3. Among them, cysteine proteases are the largest cathepsin family, including 11 proteases: cathepsins B, C, F, H, K, L, O, S, W, V, and Z.

[0003] Cathepsin C (also known as dipeptidyl peptidase I or "DPP1") is constitutively expressed in many tissues, with the highest levels in lung, kidney, liver, and spleen. Some recent publications have begun to describe the role of cathepsin C in certain inflammatory processes. For example: Adkison et al., J Clin Invest. 2002 Feb; 109(3): 363-71; Tinh et al., Archives of Biochemistry and Biophysics. 2002 403: 160-170; from these studies, cathepsin C is co-expressed with certain serine proteases in granules and plays a role in processing the precursor forms of these proteases into active forms, which are then released from the granules of inflammatory cells recruited to the site of inflammation. Once activated, these proteases have many functions, including the degradation of various extracellular matrix components, which together can propagate tissue damage and chronic inflammation.

[0004] WO 2004 / 110988 relates to certain nitrile derivatives and their use as DPP1 inhibitors.

[0005] WO 2009 / 074829 relates to peptidyl nitriles and their use as DPP1 inhibitors.

[0006] WO 2010 / 128324 relates to alpha-amino amide nitriles and their use as DPP1 inhibitors.

[0007] WO 2012 / 119941 relates to peptidyl nitrile compounds and their use as DPP1 inhibitors.

[0008] WO 2013 / 041497 relates to N-[1-cyano-2-(phenyl)ethyl]-2-azabicyclo[2.2.1]heptane-3- carboxamides and their use as DPP1 inhibitors.

[0009] WO 2001 / 096285 and WO 2003 / 048123 relate to beta-amino cyanamidines having inhibitory activity against cysteine proteases.

[0010] WO 2015 / 110826 relates to alpha-amino cyanamidines and their use as DPP1 inhibitors.

[0011] WO 2022 / 117059 provides a Cathepsin C inhibitor, which is (S)-N-((S)-1-cyano-2-(8-cyano-2-fluoro-6H-benzo[c]chromen-3-yl)ethyl)-1,4-oxazepane-2-carboxamide, having the structure of Formula I,

[0012]

[0013] The crystal form as a pharmaceutical active ingredient often affects the chemical stability of the drug. Different crystallization conditions and storage conditions can lead to changes in the crystal structure of the compound, and sometimes other forms of crystal are also produced. In general, amorphous drug products do not have a regular crystal structure, and often have other defects, such as poor product stability, fine crystallization, difficult filtration, easy caking, poor flowability, etc. The polymorphism of the drug has different requirements for product storage, production and scale-up. Therefore, it is necessary to further study the crystal form of the above-mentioned compound and improve the various properties of the above-mentioned compound. SUMMARY
