L67
Based on 2 publication(s) in Google Scholar
L67 (DNA Ligase Inhibitor) is a competitive DNA ligase inhibitor that effectively inhibits DNA ligases I/III (both IC50 are 10 μM). L67 can cause nuclear DNA damage by reducing levels of mitochondrial DNA and increasing levels of mitochondrially-generated ROS. L67 also activates the Caspase 1-dependent apoptosis pathway in cancer cells, can be used in cancer research.

In Vitro
L67 (10, 15 μM; 24 h) promotes nuclear DNA damage and (0-50 μM) increases the level of mSOX by inhibiting mitochondrial LigIIIα in HeLa cells[1].
L67 (10 μM; 24 h) induces changes in mitochondrial function that cause a reduction in OCR and mitochondrial DNA, and abnormal mitochondrial morphology in HeLa[1].
L67 (10, 100 μM; 24 h) induces apoptosis in cancer cells[1].
L67 (0-30 μM; 24 h) selectively induces cell death in cancer cells by activating a caspase 1-dependent apoptotic pathway[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:HeLa cells
-
Concentration:10, 15 μM; 0-50 μM
-
Incubation Time:24 h
-
Result:Increased the formation of nuclear γH2AX foci and steady state levels of γH2AX when at 10 or 15 μM. (γH2AX: a sign of DNA double-strand breaks).
Resulted in a concentration (0-50 μM)-dependent increase in mSOX (mitochondrial superoxide) levels. (mSOX is a major cause of the cellular oxidative damage).
-
Cell Line:HeLa cells
-
Concentration:10 μM
-
Incubation Time:24 h
-
Result:Reduced oxygen consumption rate (OCR) approximately 20%.
Resulted in about a 25% reduction in mitochondrial DNA.
-
Cell Line:HeLa cells
-
Concentration:10, 100 μM
-
Incubation Time:24 h
-
Result:Result:Induced apoptosis, and at 100 μM with apoptotic cells constituting about 50% of the HeLa cell population.
-
Cell Line:HeLa cells
-
Concentration:0-30 μM
-
Incubation Time:24 h
-
Result:Activates a caspase 1-dependent cell death pathway in cancer cells.
