Monobenzone
Based on 1 publication(s) in Google Scholar
Monobenzone is a potent skin depigmenting agent. Monobenzone induces depigmentation and exhibits good potential for vitiligo research. Monobenzone is a potent inhibitor of RNR (Ribonucleotide reductase) enzyme activity by targeting RRM2 (a regulatory small subunit M2 of RNR) protein, and thus has significant anti-leukemia efficacy in vitro and in vivo. Monobenzone inhibits acute myeloid leukemia (AML) cells proliferation and DNA synthesis, induces cell cycle arrest, and Apoptosis .

Biological Activity
Monobenzone (2.5- 40 μM, 24-48 h) inhibits AML cells proliferation with IC50s of 6-18 μM and causes dose dependent DNA synthesis inhibition, induces cell cycle arrest and apoptosis in KG-1A, MOLM13, NB4 cells[2].
Monobenzone (0-10 μM, 24-48 h) blocks DNA damage repair in KG-1A, MOLM13, NB4 cells[2].
Monobenzone (0-100 μM, 72 h) overcomes the drug resistance to Ara-C (Cytarabine (HY-13605)), DOX (Doxorubicin(HY-15142)) and HU (Hydroxyurea(HY-B0313)) in KG-1A-ARAC, KG-1A-DOX, and KG-1A-HU cells[2].
Monobenzone (0-100 μM, 72 h) with the Bcl-2 inhibitor ABT-737 (HY-50907) synergistically inhibits cell the growth with an IC50 of 2.52 μM in MOLM13 cells and an IC50 of 9.69 μM in KG-1A cells compared with monobenzone alone[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

-
Concentration:3, 10, 30, 100 μM
-
Incubation Time:72 h
-
Result:Inhibited the growth of KG-1A, KG-1A-ARAC, KG-1A-DOX, and KG-1A-HU cells in a dose-dependent manner with IC50 values of 13, 16, 24, 37 μM.
-
Cell Line:KG-1A, MOLM13, NB4 cells (AML cells)
-
Concentration:0.25, 1, 4, 16, 64, 256, 1024 μM
-
Incubation Time:72 h
-
Result:Exerted a strong, dose-dependent inhibitory effect on the proliferation of treated AML cells, with IC50 values of approximately 6-18 μM.
-
Cell Line:KG-1A, MOLM13, NB4 cells
-
Concentration:2.5, 5, 10 μM
-
Incubation Time:24 h
-
Result:Induced cell cycle arrest at the S phase.
dNTP precursors significantly reversed the cell cycle arrest in S phase, suggesting that RNR (Ribonucleotide reductase) is the active target in the treated cells, resulting in the inhibition of DNA synthesis and cell proliferation.
-
Cell Line:KG-1A, MOLM13, NB4 cells
-
Concentration:0, 1.25, 2.5, 5, 10μM
-
Incubation Time:24, 48 h
-
Result:Increased r-H2Ax dose-dependently, blocking DNA damage repair in the treated cells
Monobenzone (100 - 200 mg/kg, i.p., daily, 2 weeks) effectively inhibits AML cell (MOLM13 cells) xenograft growth in nude mice [2].

-
Animal Model:Rag1 knockout and healthy C57BL/6 mice [1].
-
Dosage:40%, 60% Monobenzone cream
