[0005] Insulin is an important peptide hormone associated with a range of diseases and disorders. It demonstrates an unparalleled ability to lower glucose in almost all forms of diabetes. Insulin is a hormone secreted by the pancreas that regulates blood glucose levels and plays a role in maintaining normal blood glucose levels. However, in people with diabetes, insulin cannot function properly due to a lack of insulin, insulin resistance, and loss of beta cell function. Consequently, blood glucose cannot be used as an energy source, leading to elevated blood glucose levels and hyperglycemia. Therefore, insulin therapy is crucial for patients with abnormal insulin secretion (type I) or insulin resistance (type II), and insulin administration is essential for regulating blood glucose levels. However, like other proteins and peptide hormones, insulin has a very short half-life in the body, thus requiring repeated administration.
[0006] Furthermore, insulin therapy can produce an overreaction, which can lead to life-threatening hypoglycemia. Hypoglycemia is a common complication of insulin replacement therapy in diabetic patients and can cause serious morbidity, including altered mental status, loss of consciousness, seizures, and death. In fact, the fear of such complications constitutes a major obstacle to strict control of blood glucose levels, and for patients with long-term type 2 diabetes, these efforts (“strict control”) may lead to increased mortality.
[0007] Therefore, there is an urgent need for new diabetes treatment technologies that can reduce the risk of hypoglycemia while preventing blood glucose levels from rising above the normal range, and at the same time exhibit an ideal half-life to limit the overall injection frequency for patients.

[0229] Unless otherwise stated, the practice of this invention will be carried out using conventional methods of protein chemistry, biochemistry, recombinant DNA technology and pharmacology within the art.
[0230] Example 1: Synthesis of insulin analogs
[0231] Figures 1A to 1M The insulin analogues shown were synthesized via a combination of solid-phase and liquid-phase synthesis. Purification of the analogues was performed by HPLC using a specific buffer and a specific reversed-phase column, which comprised a combination of ion exchange and reversed-phase media packed within the column.
[0232] Example 2: Biopotency of 8 Insulin Analogs
[0233] It was determined that they were displayed separately. Figures 1A to 1D , Figures 1H to 1J as well as Figure 1L The biopotency of eight insulin analogs was determined. The calculated insulin concentration units (IU / mL) were assigned to the eight insulin analogs using a conversion factor of 1 μIU / L = 6 picomoles / L (J Diabetes Sci Technol. May 2019;13(3): 597–600, the contents of which are incorporated herein by reference in their entirety). Figure 4 The calculated IU / mg values for eight insulin analogs are shown.
[0234] Bioequivalence of 8 insulin analogs according to Chinese Pharmacopoeia <1211> The concentration of insulin analogs and insulin reference standards was determined by comparison with the insulin reference standard. Specifically, insulin analogs and insulin reference standards were prepared using either diluent 1 or diluent 2. Diluent 1 contained 0.9% sodium chloride, pH 2.5 (adjusted with HCl), and 0.2% phenol. Diluent 2 contained 0.9% sodium chloride, pH 2.5 (adjusted with HCl). Insulin reference standards (27.2 IU / mg) and insulin analogs (calculated as 25 IU / mg) were prepared using diluent 1. Additionally, low-dose and high-dose solutions of the insulin reference standard and test analogs (0.05 IU / mL and 0.1 IU / mL, respectively) were prepared using diluent 2.
[0235] According to the Chinese Pharmacopoeia <1211> In this study, ICR mice (25-28g, 6 mice per group) were injected with 0.2-0.3 mL of low- and high-dose solutions of eight insulin analogs and insulin standards. The mice were then administered low- and high-dose insulin standards and insulin analogs according to a parallel design / protocol. Blood samples were collected from the orbital venous sinus 40 minutes after each administration. The glucose concentration of each blood sample was determined using the glucose oxidase-peroxidase method (Roche blood glucose test strips). Figure 5 The blood glucose levels after administration (i.e., 40 minutes later) are shown, and are correlated with high and low dose solutions of the analogue and reference standard, respectively. Figure 6 The relative biopotency of insulin analogs was summarized by comparing calculated and measured biopotency. Figure 7 This indicates that all eight insulin analogs tested had a glucose-lowering effect, with the three most active insulin analogs being insulin analog 2 (…). Figure 1B ), Api3545 ( Figure 1H ), Api3549 ( Figure 1L ).
[0236] Example 3: Subcutaneous administration of insulin analogs in the db / db mouse model showed controlled glucose curves over time.
[0237] The db / db mouse strain is a widely accepted model of type 2 diabetes, reproducing most aspects of human type 2 diabetes. Specifically, db / db mice carry a mutation in the leptin receptor, leading to obesity, decreased insulin receptor sensitivity, and subsequently elevated blood glucose levels, decreased β-cell function, and elevated HBA1c levels. As with human type 2 diabetes, the diabetic status in db / db mice is progressive. Animals at 6 weeks of age have near-normal or slightly elevated plasma glucose (PG) and relatively normal β-cell function. Fasting plasma glucose (FPG) levels gradually increase over several weeks, and β-cell function declines, resulting in very high FPG (>400 mg / dL) and complete β-cell degeneration by approximately 16 weeks of age. The db / db mouse model can be used for acute conditions but is more commonly used for chronic conditions to assess the cumulative effect of test compounds over several weeks of treatment. Variability is relatively low, so validating compounds with a group size of approximately 8 animals can yield good statistical significance.
[0238] Therefore, insulin analog 1 was tested. Figure 1A The ability to control glucose curves in a db / db type 2 diabetes model was assessed. Wild-type m / m mice were also included as a control in this study. Mice were male, aged 6–8 weeks, and the total group size was 8 mice. Insulin analogs were delivered subcutaneously in a single dose. The dose volume was 5 mL / kg (125 μL per 25 g mouse). Mice were injected with the following dose levels: insulin degludec 1.5 IU / kg (model) and insulin analog #1 ( Figure 1A The dosages were 0.04 mg / kg, 0.12 mg / kg, or 0.36 mg / kg. All insulin compounds (degludec insulin and analog #1) were diluted with 0.9% sodium chloride (mediator, physiological saline). The mediator control consisted of 0.9% sodium chloride.
[0239] Blood samples were collected at 0h (0-60 min before administration), 0.5h, 1h, 2h, 4h, 6h, 8h, 10h, 12h, 18h, 24h, and 30h after a single dose for measuring plasma glucose concentration. In addition, mouse body weight was measured daily for 3 days.
[0240] like Figure 2As shown, glucose curves at 2, 4, 6, and 8 hours were statistically significantly lower for all three study groups (1.5 IU / mg insulin degludec, 0.36 mg / kg, and 0.12 mg / kg analog 1) than for the db / db mediator control. Throughout the entire timeframe starting from the 2-hour time point, the glucose curve for 0.36 mg / kg analog 1 was statistically lower than that for the db / db mediator control. Furthermore, the response (reduction in glucose levels) to analog 1 at doses of 0.36 mg / kg, 0.12 mg / kg, and 0.04 mg / kg was dose-proportional.
[0241] Treatment with 1.5 IU / mg insulin degludec and analogue #1 at all dose levels had no significant effect on animal body weight, at least within the 1–3 day timeframe. Figures 3A to 3B This result indicates that insulin analog #1 can effectively regulate glucose curves while maintaining safety (by body weight).
[0242] Example 4: Efficacy of insulin analogs in non-fasting Spradolai rats
[0243] Male Spradolai (SD) rats aged 8–10 weeks were administered 175 nmol–200 nmol insulin analogs 1, 2, 3, 4, APi3545, APi3546, APi3547, and APi3549 via subcutaneous injection. Insulin degludec was used as a positive control. The mediator control consisted of glycerol (19.6 mg), m-cresol (1.72 mg), phenol (1.50 mg), zinc acetate (91.75 µg), and WFI (to 1 mL).
[0244] like Figures 8A to 8C , Figure 12 , Figures 14A to 14C and Figure 18 As shown, compared with rats injected with degludec insulin, rats injected with insulin analogs 1, 2, 3, 4, APi3545, APi3546, APi3547, and APi3549 exhibited a more sustained reduction in glucose levels. Insulin analogs 4 and APi3545 maintained low glucose levels for up to 48 hours. Insulin analog 3 showed the most thorough glucose-lowering effect.
[0245] like Figure 9 and Figure 15As shown, the area under the glucose curve (AUC) values of insulin analogs 2, 3, and 4 followed their specific activity order. Furthermore, compared to rats injected with degludec insulin, rats injected with insulin analogs 1, 2, 3, 4, APi3545, APi3546, APi3547, and APi3549 exhibited a more sustained reduction in glucose levels. Insulin analogs 4 and APi3545 maintained low glucose levels for up to 48 hours. Insulin analog 3 showed the most thorough glucose-lowering effect.
[0246] like Figure 10 As shown, rats injected with insulin analog 2 exhibited a more sustained decrease in glucose levels compared to rats injected with degludec insulin.
[0247] like Figures 11A to 11C and Figures 17A to 17B As shown, compared with rats injected with degludec insulin, rats injected with insulin analogs 1, 2, 3, 4, APi3545, APi3546, APi3547, and APi3549 maintained C-peptide levels for a longer period. Insulin analog 2 showed the most thorough and longest-lasting C-peptide reduction effect. Insulin analog APi3545 maintained undetectable C-peptide levels for up to 72 hours.
[0248] like Figure 13 and Figure 16 As shown, rats injected with insulin analogs 1, 2, 4, APi3547, and APi3546 exhibited a smaller rate of weight gain compared to rats injected with degludec insulin.

[0252] In A-14, Gly is replaced with Aad; in B-16, His(3-Me) is replaced with Pal; and in B-25, His(3-Me) is replaced with Pal; and in B-25, His(3-Me) is replaced with 3-Pal. The fatty acid residues are linked to B-Lys. 29 It is almost equivalent to insulin analogs.
[0253] The substitutions in degludec insulin (Tyr→Aad in A14, Tyr→His(5-I) in B-16, and Phe→Ala(4-thiazolyl) in B-25) produced the longest-acting insulin analog tested (APi3545).
[0254] Compared to insulin degludec, all tested structural variations enhanced and prolonged the glucose-lowering effect of insulin analogs.
[0255] Example 6: Interaction between in vitro insulin analogs and IGF-1R receptors
[0256] Insulin-like growth factor (IGF-1R) is a tyrosine kinase receptor that regulates cell growth and proliferation and can be activated by IGF-1, IGF-2, and insulin.
[0257] The IGF-1R signaling pathway regulates multiple cell phenotypes related to tumor cell survival and growth, including cell cycle progression, apoptosis, and differentiation.
[0258] Epidemiological studies have reported a positive correlation between circulating IGF-1 levels and various primary cancers, such as breast cancer, colorectal cancer, and prostate cancer.
[0259] The agency may consider the activation of the IGFR-1R receptor by insulin analogs (investigative T1D and T2D drugs) as a potential carcinogenic risk.
[0260] IGF-1R (Luc) HEK293 reporter cells were exposed to 0.015–4 mg / mL IGF-1, insulin, and insulin analogs 1, 2, 3, and 4. Figure 19 As shown, insulin analogs 1, 2, 3 and 4 did not exhibit IGF-1R activation at concentrations up to 4 µg / mL (1.6 µM).
