Handling Instructions Technical Support

Acriflavine (Acriflavinium chloride) is a fluorescent acridine dye that can be used to label nucleic acid. Acriflavine is an antiseptic agent. Acriflavine is a potent HIF-1 inhibitor that prevents the dimerization of HIF-1α and HIF-1β subunits. Acriflavine inhibits the interaction between monocarboxylate transporter 4 (MCT4) and Basigin. Acriflavine is used in cancer research, such as breast cancer, brain tumor and chronic myeloid leukemia. Acriflavine is a potent papain-like protease (PLpro) inhibitor, which inhibits SARS-CoV-2.

Description

Acriflavine (Acriflavinium chloride) is a fluorescent acridine dye that can be used to label nucleic acid. Acriflavine is an antiseptic agent. Acriflavine is a potent HIF-1 inhibitor that prevents the dimerization of HIF-1α and HIF-1β subunits. Acriflavine inhibits the interaction between monocarboxylate transporter 4 (MCT4) and Basigin. Acriflavine is used in cancer research, such as breast cancer, brain tumor and chronic myeloid leukemia. Acriflavine is a potent papain-like protease (PLpro) inhibitor, which inhibits SARS-CoV-2[1][2][3][4][5][6].

In Vitro

Acriflavine inhibits MCT4-Basigin dependent Rluc activity in a dose-dependent fashion with an IC50 of 4.6 μM. The IC50 for Acriflavine inhibiting NhRL-MCT1/ Basigin-ChRL interaction is calculated to be ~19.5 μM[3].
Acriflavine (5 μM; treatment for 24 hours) does not significantly affect hypoxia-induced lactate production and secretion in HSR-GBM1 cells[3].
Acriflavine (1-25 μM; treatment for 72 hours) reduces the clonogenic potential of several neurosphere-derived cells and is more obvious under hypoxic conditions[3].
Acriflavine (1-10 μM; treatment for 24 hours) inhibits the replication of SARS-CoV-2 in Vero and A549ACE2+ cells and has low cytotoxicity[6].

Animal Model: NOG mice (male and female, 6-8-week-old) with HSR-GBM1-Luc cell - derived xenografts (subcutaneous injection of HSR-GBM1-Luc cells into the left and right flanks)[5].
Dosage: 8 mg/kg
Administration: Intraperitoneal injection, once a day, 13 times or 15 times
Result: Inhibited tumor growth.
Also reduced tumor microvessel density, indicating inhibition of tumor vascularization.
Animal Model: C57BL/6J-CD45.1 mice (8-10-week-old) with BCR/abl-induced chronic myeloid leukemia (retroviral transduction of BCR/abl into bone marrow cells and transplantation into recipient mice)[3].
Dosage: 8 mg/kg
Administration: Intraperitoneal injection, once a day, 10 days
Result: Reduced splenomegaly, lung infiltrate with myeloid cells, and white blood cell count in peripheral blood.
Decreased the percentage and number of GFP+/CD34-/LSK cells in bone marrow, indicating a reduction in leukemia stem cells.
Animal Model: K18-ACE2 transgenic mice (female, 8-10-week-old) infected with SARS-CoV-2 (intranasal infection with the virus)[6]
Dosage: 100 mg/kg, 5 mg/kg or 15 mg/kg
Administration: Oral administration once a day, intramuscular injection twice a day, 6 days
Result: Blocked the infection in the brain and significantly reduced the viral load in the lungs. The effect was more pronounced with oral administration.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
