Licoisoflavone A is an orally active isoflavone. Licoisoflavone A inhibits proliferation, induces apoptosis, and causes G1/S phase arrest in colorectal cancer (CRC) cells. Licoisoflavone A inhibits the CDK2-Cyclin E1 axis. Licoisoflavone A inhibits lipid peroxidation with an IC₅₀ of 7.2 μM. Licoisoflavone A shows a dose-dependent inhibition effect on SARS-CoV-2 infection. Licoisoflavone A exhibits significant anti-tumor efficacy in mice bearing CT26 cell subcutaneous xenografts. Licoisoflavone A can be used for the study of colorectal cancer and SARS-CoV-2 infection.

Licoisoflavone A (0-100 μM) inhibits RNA-dependent RNA polymerase (RdRp) and cAMP-specific 3’,5’-cyclic phosphodiesterase 4 (PDE4) with IC₅₀ values of 47.31 μM and 1.77 μM, respectively^[1].
Licoisoflavone A (5 μM, 2 days) significantly reduces the cross-sectional area of Ang II-induced hypertrophic H9c2 cells by approximately 46%^[2].
Licoisoflavone A (15 μM, 48 h) upregulates Sirt3 expression and reduces MnSOD acetylation at K68 in PE-induced neonatal rat cardiomyocytes^[2].
Licoisoflavone A (15 μM, 48 h) decreases relative ANF and BNP levels in Phenylephrine (PE) (HY-B0769)-induced hypertrophic cardiac cells, but this effect is blocked when co-treated with Sirt3 inhibitor 3-TYP (HY-108331)^[2].
Licoisoflavone A ( 6.25-25 μM, 48 h) significantly inhibits proliferation, induces apoptosis, and causes G1/S phase arrest in HCT116 and SW480 colorectal cancer (CRC) cells^[4].
Licoisoflavone A (6.25-25 μM, 48 h) downregulates CDK2, Cyclin E1, and phosphorylated Rb (p-Rb) while upregulating p27 in HCT116 and SW480 cells, inhibiting the CDK2-Cyclin E1 axis^[4].
Licoisoflavone A (1-1000000 nM, 3 days) dose-dependently inhibits viability of 5 patient-derived CRC organoids (CRCOs) with IC₅₀ values ranging from 7.02 to 82.98 μM, and shows lower toxicity to normal colorectal organoids (CNOs)^[4].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (7.06 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
