Definitions
- the present invention relates to a crystalline form of a novel compound exhibiting excellent agonistic activity on melanocortin receptors, a method for preparing the same, and a pharmaceutical composition comprising the same.
- Leptin protein is a hormone secreted by body fat cells (adipocytes), and its secretion increases with an increase in body fat content, and by regulating the functions of various neuropeptides generated in the hypothalamus, appetite, body fat It regulates various in vivo functions, including content and energy metabolism (Schwartz, et al., Nature 404, 661-671 (2000)).
- the signal transduction of appetite and weight control by leptin protein is made through the regulation of many factors downstream, the most representative of which are melanocortin, AgRP (agoutirelated peptide) and neuropeptide Y (neuropeptide). Y, NPY) hormones.
- Alpha-MSH hormone induces various physiological responses by binding to three MCR subtypes in addition to MC4R.
- Five MCR subtypes have been identified so far.
- MC1R is mainly expressed in skin cells and is involved in the regulation of melanin pigmentation (skinpigmentation)
- MC2R is mainly expressed in the adrenal gland and is mainly expressed in the glucocorticoid hormone.
- ACTH asdrenocorticotropic hormone
- MC3R and MC4R which are mainly expressed in the central nervous system, are involved in the regulation of appetite, energy metabolism, and body fat storage efficiency, and MC5R expressed in various tissues is known to regulate exocrine function (Wikberg, et al., Pharm Res 42 (5) 393-420 (2000)).
- activation of the MC4R receptor has been proven to be a major action point in the development of anti-obesity drugs because it has the effect of effectively reducing body weight by inducing a decrease in appetite and an increase in energy metabolism (Review: Wikberg, Eur. J. Pharmacol 375, 295).
- agouti protein aberrant expression animal model (agouti mouse) experiment.
- agouti protein was expressed at a high concentration in the central nervous system, and it was found that obesity was induced by acting as an antagonist of MC4R in the upper and lower thalamus (Yen, TT et al., FASEB J). 8, 479-488 (1994);Lu D., et al. Nature 371, 799-802 (1994)).
- AgRP agouti-related peptide
- Appetite inhibitors acting on the central nervous system are the main types of obesity treatment developed so far, and most of them are drugs that control the action of neurotransmitters. Examples include noradrenalin agents (phentermine and mazindol) and serotonergic agents fluoxetine and sibutramine.
- noradrenalin agents phentermine and mazindol
- serotonergic agents fluoxetine and sibutramine.
- the neurotransmitter modulator it exerts a wide range of effects on various physiological actions in addition to appetite suppression through numerous subtype receptors. Therefore, in the case of the modulators, there is a major disadvantage in that the selectivity for each subtype is lacking, and various side effects are accompanied by long-term administration.
- melanocortin agonists are neuropeptides, not neurotransmitters, and in MC4R gene KO mice, all other functions other than energy metabolism are normal. It has an advantage as an action point in that it can induce only a decrease.
- the receptor is a G-protein coupled receptor (GPCR), which belongs to the most successful category of new drug action points developed so far, and it is greatly distinguished from existing action points in that it is relatively easy to secure selectivity for subtype receptors. do.
- GPCR G-protein coupled receptor
- the crystal structure of a pharmaceutically active ingredient often affects the chemical stability of the drug.
- Different crystallization conditions and storage conditions can change the crystal structure of the compound and sometimes lead to the concomitant production of different forms of the crystalline form.
- Amorphous drug products generally do not have a regular crystal structure and often have other defects such as poor product stability, smaller particle size, difficult filtration, easy agglomeration and poor flowability. Therefore, there is a need to improve various physical properties of the product.
- a person skilled in the art cannot easily predict under what conditions a compound will crystallize effectively, and which crystal form will be advantageous in terms of reproducibility, stability, and bioavailability. There is a need.

- Example 2 N -((3 S ,5 S )-1-((3 S ,4 R )-One-( tert -Butyl)-4-(4-chlorophenyl)pyrrolidine-3-carbonyl)-5-(morpholine-4-carbonyl)pyrrolidin-3-yl)- N -((One s ,4 R Preparation of crystalline form B of sulfate of )-4-methylcyclohexyl)isobutyramide
- the compound (MC70) prepared in Preparation Example 3 was dissolved in 1-propyl alcohol, and an 85% aqueous phosphoric acid solution was added so that the molar ratio of MC70:H 3 PO 4 was 1:1, and stirred to prepare a mixed solution. It was confirmed that the mixed solution was maintained as a clear solution, so heptane was added to the mixed solution and stirred at room temperature for 4 days. Thereafter, the stirring temperature was increased to 40° C., 50° C., and 60° C., respectively, and further stirred for 1 day, 17 days, and 6 days in sequence, but no crystals were formed.
- the compound (MC70) prepared in Preparation Example 3 was dissolved in ethanol, and an 85% aqueous phosphoric acid solution was added with an aqueous phosphoric acid solution so that the molar ratio of MC70:H 3 PO 4 was 1:1, and stirred to prepare a mixed solution. It was confirmed that the mixed solution was maintained as a clear solution, and cyclohexane was added to the mixed solution and stirred at room temperature for 4 days. Thereafter, the stirring temperature was increased to 35° C., 50° C., and 60° C., respectively, and further stirred for 4 days, 3 days, and 3 days in sequence, but no crystals were formed.
- the compound (MC70) prepared in Preparation Example 3 was dissolved in acetone, and an excess of aqueous phosphoric acid solution was added to an 85% aqueous phosphoric acid solution such that a molar ratio of MC70:H 3 PO 4 was 1:8 and stirred to prepare a mixed solution. It was confirmed that the mixed solution was maintained as a clear solution, and hexane was added to the mixed solution and stirred at room temperature for 4 days. Thereafter, the stirring temperature was increased to 40° C., 50° C., and 60° C., respectively, and further stirred for 3 days, 1 day, and 1 day in sequence, but no crystals were formed.
- Powder XRPD diffraction patterns were performed using a Panalytical Xpert Pro MPD diffractometer using an incident Cu radiation beam. After compacting a sample of about 20-30 mg on a glass sample holder to have a flat surface, set the generator to 45 kV (acceration voltage) and 40 mA (filament emission) and measure in reflection mode (not-spin). did. Bragg angles (2 ⁇ ) in the range of 4 to 40° were measured with a step size of 0.026° and a Time per step condition of 51 seconds.
- Form A of the sulfate salt according to Example 1 was confirmed to be a crystalline material, and specific values of XRPD are shown in Table 1 below.
- TGA and DSC combo analysis was performed using a Mettler-Toledo TGA/DSC 3+ analyzer.
- the sample was placed in an open aluminum pan, the pan was sealed, the lid pierced, and then inserted into the TG furnace. Measurements were made by heating at a rate of 10 K/min under nitrogen from 25°C to a maximum of 350°C.
- HSM HSM was measured on a Leica DM LP microscope using a Linkman hot stage (model FTIR 600) with a TMS 93 controller. Samples were observed using a lambda plate with crossed polarizers at either 10x0.22 or 20x0.40 magnification. The sample was placed on a cover slip and another cover slip was placed over the sample and the sample was visually observed as the stage was heated. A drop of mineral oil may be added to the sample in some cases to investigate outgassing, and images were captured using a SPO Insight color digital camera with SPOT software v.4.5.9.
- solubility was measured based on the final volume of water added to the sample.
