α-glucosidase (from Saccharomyces cerevisiae) – the compound showed binding affinity to the enzyme, with enhancement factors of 9.45%, 12.64%, and 13.76% at α-glucosidase concentrations of 0.75, 1.50, and 2.25 U/mL, respectively (these values represent the specific binding ratio of the compound to the target enzyme).

| ln Vitro |
In an ultrafiltration LC-ESI-MS affinity assay, Iristectorigenin A demonstrated specific binding to α-glucosidase. The binding capacity, expressed as the enhancement factor (percentage of compound specifically bound relative to total compound in incubation), increased with higher enzyme concentrations: 9.45% at 0.75 U/mL, 12.64% at 1.50 U/mL, and 13.76% at 2.25 U/mL. This binding affinity was comparable to that of tectorigenin and irigenin, but lower than that of irisflorentin (which showed enhancement factors of 28.14%, 31.94%, and 36.75% under the same conditions). The structure-activity relationship analysis suggested that the presence of hydroxyl groups at positions R1, R2, and R3 (referring to the isoflavonoid skeleton) influences the inhibitory activity, and loss of these hydroxyls significantly reduces activity. Iristectorigenin A has similar substitution patterns on ring A but different substitution on ring C compared to tectorigenin and irigenin, leading to almost the same level of binding affinity to α-glucosidase.

| Enzyme Assay |
The ultrafiltration LC-MS screening for α-glucosidase inhibitors was performed as follows: 20 μL of B. chinensis extract (100 mg/mL) was mixed with 80 μL of α-glucosidase (10 U/mL, dissolved in ammonium acetate buffer at pH 6.8) at varying concentrations (0.75, 1.50, and 2.25 U/mL) and 100 μL of ammonium acetate buffer (pH 6.8) to a total volume of 200 μL. The mixture was incubated at 37°C for 40 minutes. Then, ultrafiltration was carried out using a centrifuge with a 30-kDa molecular weight cutoff ultrafiltration membrane filter at 12,000 rpm for 10 minutes at 25°C. The filter was washed three times by centrifugation with 100 mL aliquots of ammonium acetate buffer (pH 6.8) to remove unbound low-mass molecules. The bound isoflavonoids were released by adding 100 mL of methanol solution (50:50 v/v, pH 3.1), followed by centrifugation at 12,000 rpm for 10 minutes. This release step was repeated three times. A control group experiment with denatured enzymes was also carried out before each screening experiment. The ultrafiltrate samples were directly injected into the LC-MS system for analysis. The mobile phase consisted of water (solvent A) and acetonitrile (solvent B) with a gradient program at a flow rate of 0.5 mL/min. ESI-MS in positive mode was used for data collection. The binding of a ligand to α-glucosidase was calculated using the equation: enhancement factor (%) = (A1/A2) × 100%, where A1 is the amount of compound specifically bound to α-glucosidase and A2 is the total amount of compound in the reaction.

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
