Description
Beauvericin (CAS 26048-05-5) induces apoptosis in A549 cancer cells.1 Disrupts mitochondrial volume regulation.2 Antifungal activity acting via inhibition of both multidrug efflux and TORC1 kinase.3 Crosses the blood-brain barrier in mice.4 Inhibits HIV-1 integrase.5
Chemical Properties
White powder
Uses
Beauvericin is a cyclic depsipeptide isolated from several fungal genera, notably Beauveria and Fusarium, first reported in 1969. Beauvericin exhibits broad antifungal, antibacterial, antiprotozoan and insecticidal activities. At the molecular level, beauvericin exhibits ionophore properties, and inhibits acyl-CoA:cholesterol acyltransferase activity. Beauvericin induces apoptosis by elevating intracellular calcium levels.

Uses
Toxic depsipeptide with antibiotic and insecticidal effects.
Definition
ChEBI: A trimeric cyclodepsipeptide composed from alternating methylphenylalanyl and hydroxyvaleryl residues.
Biological Activity
Depsipeptide belonging to the enniatin family. Active against gram-positive bacteria and mycobacteria. Also active against insects and brine shrimp. The ion-complexing capability allows it to transport alkaline earth metal and alkali metal ions across cell membranes. Has been shown to potentiate the antifungal activity of miconazole.
in vivo
Beauvericin (5 mg/kg; i.p.; after the first dosing cycle, observe for two days and continue the second dosing cycle) reduces tumor volume and increases necrosis in allogeneic transplant model mice[3].
Beauvericin (3, 5, 7 mg/kg; i.p.; once a week for three weeks) can significantly inhibit the growth of H22 allogeneic transplant model mice and increase the levels of TNF-α and IL-2 in mice[5].
| Animal Model: | BALB/c mice injected subcutaneously with mouse CT-26 colon cancer cells on the right side[3] |
| Dosage: | 5 mg/kg |
| Administration: | ntraperitoneal injection (i.p.)；The drug was administered on the third day after the injection of colon cancer cells and continued once a day for five days, then stopped for two days of observation, and continued on the tenth day after the injection of colon cancer cells, and continued once a day for four days. |
| Result: | Reduced the average tumor volume by 52.8 % and the average tumor weight by 60 %. |
| Animal Model: | Human cervical cancer KB-3-1 xenograft mouse model[3] |
| Dosage: | 5 mg/kg |
| Administration: | Intraperitoneal injection (i.p.)； The drug was administered once a day starting on the fifth day after cervical cancer injection for five days, followed by two days of observation. The drug was administered once a day starting on the twelfth day after cervical cancer cell injection for four days. |
| Result: | Reduced the average tumor volume by 31.3 % and the average tumor weight by 31.2 %. |
