Azithromycin and Roxithromycin define a new family of “senolytic” drugs that target senescent human fibroblasts

Abstract excerpt

Here, we employed a "senolytic" assay system as a screening tool, with the goal of identifying and repurposing FDA-approved antibiotics, for the targeting of the senescent cell population. Briefly, we used two established human fibroblast cell lines (MRC-5 and/or BJ) as model systems to induce senescence, via chronic treatment with a DNA-damaging agent, namely BrdU (at a concentration of 100 μM for 8 days). Cell...
