Description

[Technical Field]

[0001] Technical field This application relates to the technical field of polypeptides, specifically calcitonin analogs and derivatives, and their uses. [Background technology]

[0002] background Amylin is a polypeptide hormone consisting of 37 amino acids, secreted by pancreatic islet β-cells along with insulin, and is deficient in diabetic patients. This substance functions in several different organ systems, primarily through amylin receptors 1-3 (AMYR1-3). Amylin can inhibit glucagon secretion, slow gastric emptying, signal satiety, and suppress appetite. Clinical studies have shown that amylin receptor agonists may be used to treat overweight, obesity, type 1 diabetes, and / or type 2 diabetes. An amylin analog known as pramulintide (trade name Simulin) can lower blood glucose levels and may be used to treat patients with diabetes who are taking insulin. However, pramulintide has a half-life of less than one hour and is administered with meals, so patients need to take this drug several times a day for treatment. Pramulintide is unstable, prone to fibrillation at neutral pH, and precipitates, rendering it ineffective, so it is supplied in an acidic solution.

[0003] Calcitonin is a hormone produced by the thyroid gland that regulates the concentration of calcium and phosphate in the blood. Calcitonin receptors are present in many tissues throughout the body and are involved in regulating bone remodeling. Salmon calcitonin, currently marketed under the name Miacalsic, is useful in treating conditions such as hypercalcemia and osteoporosis. Calcitonin is also unstable at neutral pH and is therefore supplied in acidic solutions. Salmon calcitonin has a half-life of less than 2 hours and needs to be administered to patients at least once a day. Currently marketed calcitonin drugs are salmon calcitonin and elcatonin (calcitonin from eels), but due to their low molecular weight, they require daily administration by injection. Furthermore, their desirable stability is only observed under acidic conditions, and they are unstable under neutral conditions, which poses a significant obstacle to the pharmaceutical use and formulation development of these molecules.

[0004] Because natural amyrin and calcitonin receptor agonists have short half-lives, extending their half-lives is a development goal for such drugs. Furthermore, since amyrin and calcitonin receptor agonists have low stability at neutral pH and a strong tendency to fibrillate, improving their stability at physiological pH is another development goal. [Overview of the project] [Problems that the invention aims to solve]

[0211] As used herein, "derivative" refers to a product resulting from the modification of a functional group (e.g., an amino acid residue) of a biomolecule (e.g., a polypeptide or protein) with a specific group or structure (e.g., a specific small molecule structure). Examples of modifications include, but are not limited to, acylation, amidation, esterification, and thioesterification.

[0212] Abbreviation The corresponding names or structures of some of the abbreviations used in the embodiments of this application are as follows:

[0213] [Table 1]

[0214] Exemplary embodiments of this application are described below, but various details of the embodiments in this application are included for the sake of clarity and should be interpreted as illustrative only. Accordingly, it will be understood by those skilled in the art that many variations and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. For clarity and conciseness, descriptions of well-known functions and structures are also omitted in the following description. [Examples]

[0215] Examples Example 1 Preparation of polypeptide derivatives Polypeptides were synthesized by solid-phase organic synthesis, specifically by solid-phase peptide synthesis (SPPS) using Fmoc-protected amino acids, followed by cleavage, oxidation, and purification to obtain the target product. Taking the compound caglirintide (referred to as "D1") as an example, the synthesis process is as follows.

[0216] 1.1 Solid phase synthesis Using Fmoc-linker MBHA resin S=0.32 mmol / g and employing Fmoc / tBu treatment, amino acids were sequentially condensed from the C-terminus to the N-terminus (right to left) according to the peptide sequence, as shown in Table 1.

[0217] [Table 2]

[0218] The following amino acids were coupled in order: A-01 Fmoc-Pro-OH, A-02 Fmoc-Thr(tBu)-OH, A-03 Fmoc-Asn(Trt)-OH, A-04 Fmoc-Ser(tBu)-OH, A-05 Fmoc-Gly-OH, A-06 Fmoc-Val-OH, A-07 Fmoc-Asn(Trt)-OH, A-08 Fmoc-Thr(tBu)-OH, A-09 Fmoc-Pro-OH, A-10 Fmoc-Pro-OH, A-11 Fmoc-Leu-OH, A-12 Fmoc-Ile-OH, A-13 Fmoc-Pro-OH, A-14 Fmoc-Gly-OH, A-15 Fmoc-Phe-OH, A-16 Fmoc-Asn(Trt)-OH, A-17 Fmoc-Asn(Trt)-OH, A-18 Fmoc-Ser(tBu)-OH, A-19 Fmoc-Ser(tBu)-OH, A-20 Fmoc-His(Trt)-OH, A-21 Fmoc-Arg(Pbf)-OH, A-22 Fmoc-Leu-OH, A-23 Fmoc-Phe-OH, A-24 Fmoc-Glu(OtBu)-OH, A-25 Fmoc-Ala-OH, A-26 Fmoc-Leu-OH, A-27 Fmoc-Arg(Pbf)-OH, A-28 Fmoc-Gln(Trt)-OH, A-29 Fmoc-Thr(tBu)-OH, A-30 Fmoc-Ala-OH, A-31 Fmoc-Cys(Trt)-OH, A-32 Fmoc-Thr(tBu)-OH, A-33 Fmoc-Ala-OH, A-34 Fmoc-Thr(tBu)-OH, A-35 Fmoc-Asn(Trt)-OH, A-36 Fmoc-Cys(Trt)-OH, A-37 Fmoc-Lys(Boc)-OH, A-38 Fmoc-Glu-otbu and A-39 C20 diacid.

[0219] Finally, polypeptide derivatives were formed on the resin.

[0220] The polypeptide derivatives on the resin were washed, removed, and dried to a certain weight for cutting.

[0221] 1.2 Cutting Formula of the cleavage reagent: The cleavage reagent was TFA:H2O:EDT:TIS = 95:1:2:2, and the amount used was 10 mL ± 2 mL per gram of peptide-on resin. The H2O, TFA, EDT, and TIS components of the required cleavage reagent were added sequentially to the cleavage reaction flask, and the temperature was controlled to 0-10°C. The cleavage reagent was added to the resin under stirring, and after the system temperature stabilized, it was stirred for a further 2.5 hours at a controlled temperature of 25-30°C. The cleavage solution was filtered and precipitated using 5 times the volume of liquid ice diethyl ether. The precipitate was filtered, washed three times with 3 times the volume of liquid ice diethyl ether, and then dried under reduced pressure at room temperature to obtain the crude solid product.

[0222] 1.3 Oxidation The crude product was finely ground and slowly added to purified water while stirring, dropwise adding an aqueous acetonitrile solution. After the crude product was added and completely dissolved, a methanol solution of iodine was added and the mixture was stirred for 30 minutes.

[0223] 1.4 Purification and freeze-drying The oxidizing solution described above was filtered through a 0.45 μm microporous filtration membrane. The crude product was separated and purified at room temperature using a column prepared with a C-18 column packing material having a suitable gradient, and then the target product was recovered, detected, analyzed, and sorted. A purity of 90% or higher was required. The off-specification target product was recovered, separated and purified again with a suitable gradient, and a suitable liquid peak was obtained. The above suitable liquid samples were freeze-dried under reduced pressure to obtain a freeze-dried powder of the purified polypeptide.

[0224] Table 2 shows polypeptides and derivatives prepared using a method similar to that described in Example 1 of this application. D2 represents the sequence of natural salmon calcitonin, D1 and D3 represent the sequences of modified calcitonin in the prior art, and the remainder are calcitonin analogs or derivatives provided in this application, wherein the fatty acid moiety of the polypeptide derivative is located outside the fatty acid-containing side chain for modification of the amino acid sequence and is therefore located at the distal end of the binding of the side chain to the amino acid sequence.

[0228] [Table 6]

[0229] Example 2 Activity test of derivatives in cells The purpose of this assay is to test the activity or potency of calcitonin analogs or derivatives against the human amyrin receptor in vitro using a luciferase assay.

[0230] 2.1 Construction of an amyrin receptor / CRE-luc cell line Using a standard protocol, CHO-K1 / Ga15 / AMY3 cells (purchased from GenScript, with calcitonin receptor and receptor activity-modifying peptide (RAMP) already constructed) were transfected with a plasmid containing a luciferase expression cassette with multiple copies of the cAMP response element (CRE). The cells were cultured in F12 medium containing 200 ug / mL zeosin, 2 ug / mL puromycin, 100 ug / mL hygromycin, and 400 ug / mL G418 to obtain a stably transfected amyrin receptor / CRE-luc cell line.

[0231] 2.2 Amylin Luciferase Assay The lyophilized powder obtained according to the method of Example 1 was dissolved in 20 mM phosphate buffer at pH 7.0 and diluted with growth medium (F12 culture medium containing 10% FBS) to obtain a derivative sample with an initial concentration of 10 nM. This sample was then subjected to 5-fold serial dilution with growth medium to obtain seven samples at concentrations including 10 nM, 2 nM, and 0.4 nM. 50 μL of the tested sample solution at each concentration was added to each well of a white 96-well plate.

[0232] Stable transfected amyrin receptor / CRE-luc CHO cells were resuspended in growth medium at a constant density, and 50 μL of the cell suspension was added to a white 96-well plate containing the test sample solution at a density of approximately 20,000 cells per well. After incubation at 37°C and 5% CO2 for 24 hours, 100 μL of luciferase substrate was added to each well and incubated for 3 minutes. Finally, luminescence was tested using SpectraMax L (Molecular Devices) with SoftMax Pro 7.0.3 GxP software. A standard curve was plotted using fluorescence intensity to calculate EC50. The results are shown in Table 3 below.

[0233] [Table 7]

[0234] The data in the table shows that most of the calcitonin analogs or derivatives provided in this application have strong activity against intracellular amyrin receptors, and that some derivatives have activity values ​​an order of magnitude higher than those of prior art calcitonin analogs or derivatives.

[0235] Example 3: Thermally Accelerated Stability Assay 3.1 Materials and Devices A stability testing chamber (BINDER GmbH), a 0.01 mg reading balance (METTLER TOLEDO), a pH meter (METTLER TOLEDO), a biosafety cabinet (ESCO), a T2G-II small motor-driven capping machine (Changsha zhongya pharmaceutical equipment co. LTD), a high-speed refrigerated centrifuge (Eppendorf), a sterilization cabinet (Shinva Medical), an Agilent 1260 high-performance liquid chromatograph, and a Sepax Bio-C18 4.6*250 mm 3 μm 200 Å reversed-phase column were used.

[0236] Reagents and consumables include ultrapure water (18.2 MΩ, automated), acetonitrile (HPLC grade), trifluoroacetic acid (HPLC grade), sodium dihydrogen phosphate (pharmaceutical grade, Hunan Jiudian Hongyang Pharmaceutical Co., Ltd), hydrochloric acid (pharmaceutical grade, Hunan Er-Kang Pharmaceutical Co., Ltd.), sodium hydroxide (analytical reagent grade, Hushi®, Sinopharm Chemical Reagent Co., Ltd.), vials, rubber stoppers, disposable syringes, and sterile filters.

[0237] 3.2 Assay Method Lyophilized powder (1 mg / mL) of a calcitonin analog or derivative prepared according to the method of Example 1 was mixed with sodium dihydrogen phosphate (1.42 mg / mL) and dissolved in ultrapure water in the indicated mass-to-volume ratio. After adjusting the pH to approximately 7.4 with hydrochloric acid / sodium hydroxide, the solution was filtered into a sterile vial in a clean bench using a 0.22 μm sterile filter. The vial was then capped and placed in a stability test chamber at 40°C. Detection was performed on day 7 (7d) and day 26 (26d), and changes in the characteristics and properties of the polypeptide were observed and recorded during the assay. The mixture was then centrifuged at 10000 rpm at 4°C for 3 minutes, and the supernatant was transferred to a liquid-phase sample vial. The polypeptide concentration and purity were detected using the following liquid-phase chromatography (where polypeptide concentration = peak area / injection volume / extinction coefficient / 60 × flow rate, polypeptide purity = target peak area / total peak area × 100%).

[0238] The conditions for reversed-phase chromatography were: flow rate: 1.0 ml / min, autosampler temperature: 15°C, column temperature: 25°C, detection wavelengths: 280 nm and 214 nm, mobile phase A: 100% H2O + 0.05% TFA, mobile phase B: 100% ACN. The elution gradient is shown in Table 4.

[0239] [Table 8]

[0240] 3.3 Assay Results The results are shown in Tables 5, 6, and 7. A difference of 5% or more in content compared to the initial value was generally assumed to be a significant change (for example, as defined in the Chinese Pharmacopoeia (2020 edition)). Within a reasonable margin of error, a decrease of less than 1% from the initial value to the detected content is indicated below as "no change".

[0241] [Table 9]

[0242] As shown in Table 5, the calcitonin analogs or derivatives provided in this application showed no significant changes in properties or characteristics in a thermally accelerated stability assay under neutral conditions. On day 7 of the accelerated test, the solution remained clear, indicating little to no characteristic or property changes in the polypeptide. Molecules such as M8, M9, and M13 showed no significant changes in properties or characteristics, and remained in a clear solution even on day 26 of the accelerated test, demonstrating fairly stable properties and characteristics.

[0243] [Table 10]

[0244] Table 6 shows that there was no significant change in the concentration of the calcitonin analogs or derivatives provided in this application during thermally accelerated stability assays under neutral conditions. The concentration change was less than 4% for all on day 7 of the accelerated test, and for some calcitonin analogs or derivatives, it was close to 1% (e.g., M5) or even less than 1% (indicated as "no change," e.g., M8 and M13). M8 and M13 showed high concentration stability, with a concentration change of less than 2% on day 26 of the accelerated test compared to day 0.

[0245] [Table 11]

[0246] Table 7 shows that there was no significant change in the purity of the calcitonin analogs or derivatives provided in this application during the thermally accelerated stability assay under neutral conditions. On day 7 of the accelerated test, the purity change of most polypeptide solutions was less than 1% as determined by reverse-phase chromatography, or no decrease in purity was observed at all. Molecules such as M5, M8, M9, and M13 were further found to have less change in purity or even less significant change on day 26 of the accelerated test, demonstrating high purity stability. In contrast to the 18% purity decrease of molecule D3 in the prior art on day 26 of the thermally accelerated assay (see Figure 1), the purity of the calcitonin analog M5 of this application decreased by only 0.68% at the same point (see Figure 2). A comparison of the purity changes of the calcitonin derivative M8 provided in this application and D1 (caglirintide, Novo Nordisk) in the thermally accelerated assay is shown in Table 8, and the reverse-phase chromatography spectra of molecule M8 before and after the thermally accelerated assay are shown in Figure 3. The differences in the backbones of M8 and D1 are evident from the data in Table 8 and Figure 3, with the former exhibiting superior stability under neutral conditions.

[0247] [Table 12]

[0248] As demonstrated by the data in this application, the calcitonin analogs and derivatives provided herein exhibited significantly higher stability in thermo-enhanced assays compared to those of the prior art.

[0249] Example 4 Thermally accelerated stability assay for suitability testing Calcitonin analog M8 (1 mg / ml), GLP-1 receptor agonist M51 (1 mg / ml), and sodium dihydrogen phosphate (1.42 mg / ml) were mixed and dissolved in ultrapure water. 5.5 mg / ml of phenol and 14 mg / ml of 1,2-dihydroxypropane were further added to the test group containing the excipients. After adjusting the pH to approximately 7.4 with hydrochloric acid / sodium hydroxide, an accelerated stability assay was performed according to the method of Example 3. The results are shown in Figure 4 (without excipients) and Figure 5 (with excipients). M8 was well miscible with M51 and showed only slight changes in the reverse-phase chromatography spectrum after a 1-month thermal accelerated assay under the same formulation conditions as M51. Therefore, they had the potential to be developed as co-formulations. As shown in the results of this thermal accelerated assay, the calcitonin analogs or derivatives provided herein exhibit remarkably good stability, for example, molecule M8, which has excellent thermal stability both as a single drug and in combination with M51 under the same formulation conditions.

[0250] Example 5: Tests on body weight changes and food consumption in animals This study used Sprague Dolly (SD) rats weighing 200–250 g. Rats were received at least 10–14 days prior to the start of the experiment to allow for adaptation to the experimental environment. Upon arrival, rats were exposed to a reverse light-dark cycle (lights off during the day, lights on at night) for two weeks, and individually housed for the first week to improve data accuracy and test sensitivity. Throughout the acclimatization and experimental periods, rats had free access to food and water. Five–eight rats were assigned to each derivative test group, and a dose of 10 nmol / kg of the derivative or vehicle was administered subcutaneously, with the administration time recorded for each group. After administration, rats were returned to cages and provided with access to food and water. Rats' food intake and body weight changes were recorded online or manually every 24 hours.

[0251] The experimental results for Group 1 and Group 2 are shown in Figures 6 and 7, and Figures 8 and 9, respectively. The calcitonin analogs and derivatives of this application were suggested to have a significant effect in reducing rat body weight and food intake.

[0252] Figures 6 and 7 further demonstrate that the calcitonin analogs of this application have superior effects compared to D1 in terms of weight loss and appetite suppression, and that M18, M9, and M13 are particularly effective.

[0253] Figures 8 and 9 further demonstrate that the calcitonin analogs and derivatives of this application, such as M8, M19, and M20, have a significant effect on reducing both body weight and food intake in rats.

[0254] While embodiments of this application have been described above, this application is merely illustrative and indicative, and is not limited to the specific embodiments and fields of application described above. Many variations can be conceived by those skilled in the art without departing from the claims of this application.
