- Nuclear factor of activated T-cells cytoplasmic 1 (NFATc1) [1]
- β-Secretase 1 (BACE-1) (IC50 = 28.6 ± 2.3 μM) [2] - UDP-glucuronosyltransferases (UGTs): UGT1A1 (IC50 = 35.2 ± 3.1 μM), UGT1A3 (IC50 = 42.5 ± 2.8 μM), UGT1A6 (IC50 = 51.7 ± 3.5 μM), UGT1A9 (IC50 = 48.3 ± 3.2 μM), UGT2B7 (IC50 = 68.4 ± 4.1 μM) [3] |

| ln Vitro |
- Bavachalcone inhibited RANKL-induced osteoclast differentiation in mouse bone marrow macrophages (BMMs) in a dose-dependent manner. At concentrations of 5, 10, and 20 μM, it reduced the number of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated osteoclasts by 32±4%, 58±5%, and 75±6%, respectively [1]
- It downregulated the expression of osteoclast-specific genes and proteins: 20 μM Bavachalcone reduced NFATc1 and c-Fos mRNA levels by 68±5% and 59±4%, and protein levels by 72±6% and 65±5%, respectively [1] - The compound inhibited BACE-1 activity, with an IC50 value of 28.6 ± 2.3 μM, and showed no significant inhibitory effect on trypsin or chymotrypsin at 100 μM [2] - It exhibited selective inhibitory effects on UGT isoforms: strongly inhibiting UGT1A1, 1A3, 1A6, 1A9, and 2B7, while showing no significant inhibition on UGT2B4 even at 100 μM [3] - No significant cytotoxicity was observed in BMMs at concentrations up to 20 μM [1] |
| Enzyme Assay |
- BACE-1 activity assay: Recombinant BACE-1 was incubated with a fluorogenic substrate and Bavachalcone (10–100 μM) at 37°C for 1 hour. The fluorescence intensity of the cleaved substrate was measured at excitation/emission wavelengths of 320/405 nm to calculate inhibition efficiency and IC50 value [2]
- UGT activity assay: Human liver microsomes or recombinant UGT isoforms were mixed with Bavachalcone (10–100 μM), UDP-glucuronic acid (cofactor), and 4-methylumbelliferone (substrate). After incubation at 37°C for 60 minutes, the reaction was terminated, and the fluorescence of the glucuronidated product was measured at 365/450 nm to determine IC50 values [3] |
| Cell Assay |
- Osteoclast differentiation assay: Mouse BMMs were seeded in 96-well plates and cultured with M-CSF (30 ng/mL) and RANKL (50 ng/mL) in the presence of Bavachalcone (5, 10, 20 μM) for 5 days. Cells were fixed, stained for TRAP, and multinucleated (≥3 nuclei) TRAP-positive cells were counted as osteoclasts [1]
- Gene and protein expression assay: BMMs were treated with Bavachalcone (20 μM) and RANKL for 3–5 days. Total RNA was extracted for RT-PCR to detect NFATc1 and c-Fos mRNA levels; cell lysates were prepared for Western blot analysis of the corresponding proteins [1] - Cell viability assay: BMMs were seeded in 96-well plates, treated with Bavachalcone (5, 10, 20, 40 μM) for 5 days, and cell viability was measured by MTT assay [1] |

| Additional Infomation |
Bavachalcone is a chalcone compound. It has been reported to exist in Psoralea corylifolia, Broussonetia papyrifera, and Sophora prostrata, with relevant data. Bavachalcone is a phenolic chalcone compound isolated from the seeds of Psoralea corylifolia [1][2][3]. Its anti-osteoclastogenic mechanism involves the inhibition of RANKL-induced NFATc1 and c-Fos expression, which are key transcription factors for osteoclast differentiation [1]. BACE-1 inhibitory activity suggests its potential use in treating Alzheimer's disease by reducing β-amyloid production [2]. Inhibition of UGT isoenzymes suggests a potential risk of drug interactions, as UGT is a key enzyme in drug metabolism and detoxification [3].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
