Abstract
Description
[Technical Field]
[0001] This invention relates to an improved crystal form of SCO-101, its preparation, and its uses. Furthermore, this invention relates to an intermediate crystal form of SCO-101 that can be converted into an improved crystal form of SCO-101. [Previous Technology]
[0002] Cancer is a heavy burden on our society, with approximately 18 million new cancer cases diagnosed in 2019. Despite the introduction of many new treatment modalities / options, primary or acquired resistance to the applied treatment still represents the leading cause of cancer death.
[0003] Compound SCO-101, also known as NS3728, was first described in WO 2000 / 24707. SCO-101 has since been shown to be a potent enhancer of a series of anticancer agents and is currently being developed for use in combination therapies for cancer, particularly for the treatment of resistant cancers. WO 2017 / 198700 describes SCO-101 and its use in combination therapies for the treatment of cancer.
[0004] A series of substituted diphenylureas, including SCO-101, can be prepared as described in WO 2000 / 24707 by mixing suitable starting materials soluble in toluene, thereby causing SCO-101 to precipitate upon formation. SCO-101 prepared in toluene using the conditions of WO 2000 / 24707 is crystalline. [Summary of the Invention]
[0005] The inventors have discovered that the polymorphic form of SCO-101 prepared as described in WO 2000 / 24707 is not a thermally stable form, but rather a hygroscopic metastable polymorphic form. This polymorphic form of SCO-101 prepared as described in WO 2000 / 24707 is referred to herein as crystal form II. Furthermore, SCO-101 has shown a tendency to form solvates and exhibits several polymorphs. Therefore, from a pharmaceutical development and patient safety perspective, there is a need for a more stable crystal form that is free of solvates (anhydrous). In addition, there is a need to provide a metastable form that can be converted into the desired thermally stable form (referred to herein as crystal form I). The inventors have further demonstrated that the thermally stable crystal form I is unexpectedly non-hygroscopic, making crystal form I of SCO-101 a more attractive crystal form for clinical development.

Implementation Method
[0032] Definition
[0033] The terms "polymorph" or "polymorphic form" as used herein refer to the polymorphic form of SCO-101. Solids exist in amorphous or crystalline forms; the crystalline form is also referred to herein as the crystal form. In the case of a crystalline form, the crystal molecules are located in three-dimensional lattice positions. When a compound recrystallizes from a solution or slurry, it may crystallize with different spatial lattice arrangements; this is a characteristic known as "polymorphism," in which different crystalline forms are referred to as "polymorphs." Different polymorphic forms of a given substance may differ from each other in one or more physical properties, such as solubility and dissociation, true density, crystal shape, compressive behavior, flow properties, and / or solid-state stability. In the case of a chemical substance existing in two (or more) polymorphic forms, the unstable form generally transforms into a more thermally stable form after a sufficient period of time at a given temperature. When this transition is not rapid, the thermally unstable form is called the "metastable" form.
[0034] Unless otherwise stated, the unit of 2θ angle is degrees (°). When 2θ angle is used to define the characteristic of the unique XRPD peak maximum of a homomorphic material, each 2θ angle includes ±0.2° to account for error margins. Therefore, the XRPD peak maximum defined by 2θ angle 10.0 will include 9.8 and 10.2, and any number in between, represented by 10.0 ± 0.2.
[0035] The term “onset temperature” as used herein refers to the designed intersection of the extrapolated baseline and the tangent line at the start of melting in the DSC / TG experiment.
[0036] As used herein, the term "peak temperature" refers to a local highest or lowest temperature that can be determined by means of differential scanning calorimetry (DSC), a method known to those skilled in the art.
[0037] The term “seeding” as used herein refers to the technique of adding one or more “seeds” to a crystallization solution to promote crystal formation.
[0038] As used herein, the term "amorphous form" refers to the non-crystalline form of a substance as determined by X-ray powder diffraction (XRPD). The term "amorphous" encompasses solids with disordered molecular arrangement and no distinguishable crystal lattice.
[0039] The term "isomorphic form" refers to the characteristic of SCO-101 existing in different crystal forms with different crystal lattices, which provides for differences in crystalline materials in aspects such as crystal hardness, shape, and size. Different crystal forms can be identified and examined by crystallographic techniques such as XRPD and DSC / TG, or indirectly by assessing differences in physical and / or chemical properties associated with each specific allomorph. Different allomorphs have different physical properties, such as solubility, dissolution, solid-state stability, and processing characteristics in terms of powder flow and compaction during tableting.
[0040] As used herein, the term "anti-cancer agent" includes, but is not limited to, chemotherapeutic agents that have activity against sensitive tumors.
[0041] The term "polar protic solvent" refers to a polar solvent that can exchange protons with a reagent and contains polarizable protons.
[0042] The term "polar aprotic solvent" refers to a polar solvent that does not contain acidic hydrogen and does not act as a hydrogen bond donor.
[0043] The term "apolar solvent" refers to a solvent having a low dielectric constant (ε) of less than 9.5 and being immiscible with water.
[0044] The term "relative humidity" or "RH" refers to the percentage ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature.
[0045] The term "hygroscopic" is used herein to describe compounds or homocrystalline forms that adsorb water by means of absorption, adsorption, or a combination of both processes.
[0046] The terms "Form I" and "crystal form I" are used interchangeably herein. This also applies to Forms I, II, III, IV, and V. Crystal form I of SCO-101
[0047] Form I of SCO-101 has been shown to be nonhygroscopic and is the most thermally stable allomorph of SCO-101. Furthermore, Form I has demonstrated superior properties compared to other non-solvable and solvable forms of SCO-101 (such as Form II). Form I has a higher melting point than Form II (Figure 2A vs. Figure 2B), and together with results from competitive slurry experiments (Example 7), it can be inferred that Form I is a more thermally stable allomorph of SCO-101 compared to the other identified forms. In addition, DVS analysis of Form I (Figure 3A) and Form II (Figure 3B) has shown that Form I is substantially nonhygroscopic, while Form II absorbs approximately 6% water (w / w) at 90% RH. These experimental observations support the viewpoint that, from the perspective of stability and nonhygroscopicity, crystalline form I of SCO-101 is the most attractive crystalline form for clinical development.

[0208] 3,5-bis(trifluoromethyl)-phenyl isocyanate (3.5 kg) was added to a stirred solution of 3.2 kg of 4-bromo-2-(1H-1,2,3,4-tetrazol-5-yl)aniline in toluene (62 L). The tube used for adding 3,5-bis(trifluoromethyl)-phenyl isocyanate was washed with toluene (3.8 L) added to the reactor. The reaction mixture was heated to 55°C and stirred for 11 hours. In-process control (IPC) confirmed the conversion of the starting material, and the reaction mixture was cooled to 23°C after 2.5 hours.

[0212] Dissolve 3 g of SCO-101 Form I in 30 mL of acetone using sonication to aid dissolution. Filter the clarified solution into a 50 mL round-bottom flask using a syringe, and remove the solvent by rotary evaporation in a 40°C water bath. Allow the solution to stand on the rotary evaporator for one hour to ensure complete drying. Obtain the solid. Decant the solid into a crystallizing dish, cover with thin paper, and dry in a vacuum oven at 40°C overnight (approximately 17 hours).

Conclusion
[0222] The anhydrous nonsolvent crystal forms of SCO-101 can be prepared using the conditions of items 1, 13 and 14 in Table 1 to provide forms I, III and IV, respectively.
[0223] Furthermore, this embodiment demonstrates the ability to form a wide range of solvates, thereby producing different crystal forms (modes) of SCO-101. The desired crystal form can be obtained by selecting the conditions described in Table 1. Example 4: Preparation of Crystal Form I Material
[0224] The crude SCO-101 material was manufactured using the method described in Example 1. Method
[0225] Crude SCO-101 (50 g, 1.0 equivalent, 101 mmol) was dissolved in 2-propanol (257 g) in a 1 L reactor. The reaction mixture was heated at 50 °C until a clear solution was obtained. Water (326 g) was added fractionally to the solution over a 30-minute period. After cooling the resulting slurry to 20 °C over a 1-hour period, the crude SCO-101 was separated by filtration. The filter cake was washed with a mixture of 2-propanol / water (50 / 50% w / w, 39 g), and then the crude SCO-101 was redissolved in acetone (154 g) at 10 ± 5 °C. Water (195 g) was then added to the solution over a period of 70 to 90 minutes. Crystallized SCO-101 was separated and washed with a mixture of acetone / water (45:55% w / w, 180 g). The product was dried in an oven at 45 °C under reduced pressure. Results
[0226] The SCO-101 Form I prepared by the above method has been analyzed by XRPD (Figure 1A), TG / DSC (Figure 2A), and DVS (Figure 3A), and has undergone the competitive slurry experiment further described in Example 7. Conclusion
[0227] SCO-101 Form I has been shown to be non-hygroscopic and is the most thermally stable allomorph of SCO-101. Furthermore, Form I has exhibited superior properties compared to other non-solvable and solvable forms of SCO-101. Form I has the highest melting point, and together with results from competing slurry experiments, it can be inferred that Form I is the most thermally stable allomorph of SCO-101. In addition, DVS analysis of Form I and Form II has shown that Form I is substantially non-hygroscopic, while Form II absorbs approximately 6% (w / w) at 90% RH.

[0230] After 24 hours, wet sample display pattern 38 was formed. The solid was recovered by centrifugation and dried at 40°C for 24 hours. Results
[0231] XRPD analysis of the solid confirmed the formation of pattern 24 (Fig. 1C). TG / DSC analysis (Fig. 2C) confirmed the formation of the nonsolvent crystal form of SCO-101. DSC analysis showed an exothermic event initiating at 162°C. VT-XRPD confirmed that the exothermic event was caused by the transformation to pattern 29 (form IV). Conclusion

[0241] XRPD analysis was performed on a PANalytical X'pert pro with a PIXcel detector (128 channels), scanning the sample between 3 and 50° 2θ. The material was gently ground to release any agglomerates and loaded onto a porous disk supported by a Mylar polymer film. The porous disk was then placed in a diffractometer and analyzed using Cu K radiation (α1λ=1.54060 Å; α2=1.54443 Å; β=1.39225 Å; α1:α2 ratio=0.5) operating in transmission mode (step size 0.0130° 2θ, step time 18.87 s). The data were visualized and images generated using the HighScore Plus 4.7 desktop application (PANalytical, 2017). Polarized Light Microscopy (PLM)
[0242] The presence of crystallinity (birefringence) was determined using an Olympus BX53 microscope equipped with a cross-polarizing lens and a Motic camera.

Thermogravimetric analysis / differential scanning calorimetry (TGA / DSC)
[0243] Approximately 5-10 mg of material was added to a pre-weighed open aluminum dish and loaded into a TA Instruments Discovery SDT 650 Auto-Simultaneous DSC, which was kept at room temperature. The sample was then heated from 30°C to 400°C at a rate of 10°C / min, during which time the sample weight change and thermal flow response (DSC) were recorded. Nitrogen gas was used as the sample purging gas at a flow rate of 200 cm³ / min. Differential Scanning Calorimetry (DSC)
[0244] Weigh approximately 1-5 mg of material into an aluminum DSC pan and seal it loosely with an aluminum cap. Then load the sample pan into a TA Instruments Discovery DSC 2500 differential scanning calorimeter equipped with an RC90 cooler. Heat the sample and reference material to 200°C at a scan rate of 10°C / min and monitor the resulting heat flow response. Cool the sample to -80°C and then reheat it to 200°C at 10°C / min.

Experiments were conducted in dimethyl deuteride and each sample was prepared at a concentration of approximately 10 mM. Dynamic vapor adsorption (DVS) was used.
[0247] Place approximately 10–20 mg of sample in the mesh tray of a vapor adsorption balance, mounted on a Surface Measurement Systems DVS Intrinsic or Advantage dynamic vapor adsorption balance. The sample is subjected to a gradual change in relative humidity (RH) from 40% to 90% in 10% increments, maintaining the sample at 25°C until a steady weight is achieved (dm / dt 0.004%, minimum step 30 min, maximum step 120 min). After the adsorption cycle is complete, the sample is dried to 0% RH using the same procedure and then restored to 40% RH using a second adsorption cycle. Two cycles are performed. The weight change during the adsorption / desorption cycles is plotted to determine the hygroscopic properties of the sample. Any solids retained are then analyzed by XRPD.

In the TG trace, a mass loss of 3.4 wt.% (0.3 equivalents of acetone or 0.97 equivalents of water) was observed between 90 °C and 155 °C. Subsequent mass losses were secondary mass losses attributable to API decomposition, namely a 49 wt.% mass loss between 180 °C and 247 °C, and an 18 wt.% mass loss between 247 °C and 305 °C.

A first-order mass loss, absent in the received material, was observed in the TG trace. This resulted in a mass loss of 11.2 wt.% (1.0 equivalent of 2-propanol or 3.5 equivalent of water) between 100°C and 150°C. Subsequent mass losses were attributed to API decomposition, namely a 46.6 wt.% mass loss between 180°C and 250°C, and a 15.6 wt.% mass loss between 250°C and 305°C. In the DSC trace, an additional endothermic event, absent in Form I, was observed, initiating at 124 °C, coinciding with the mass loss of 2-propanol. This was followed by an endothermic event initiating at 220 °C, attributed to API decomposition, and then an exothermic event initiating at 271 °C. These data support the isopropanol solvate of Form V as described in this invention. (a) Enthalpy (normalized): 81.609 J / g; Peak temperature: 132.09 °C; Initiation temperature: 123.79 °C.

An increase in mass of approximately 6% was observed at 90% relative humidity. The 3% weight increase as RH increases from 70% to 80% corresponds to the formation of the monohydrate, and the total 6% weight increase corresponds to the dihydrate. This figure shows that form II is hygroscopic.
