VP-4604 (2.5 mM) showed low toxicity towards mammalian cells and was tolerated by mammalian cells (HaCaT, lymphocytes) with inhibition growth (%) of 44.1% and >50%, respectively.[1]
VP-4604 (2.5 mM, 18 h) inhibits drug-resistant S. aureus and P. aeruginosa with growth inhibition (%) GI >95% [1].
VP-4604 shows low cytotoxicity with a CC 50 value >118.4 mM towards HEK-293 (human embryonic kidney) ATCC CRL‐1573 and an HC 10 vaule >118.4 μM towards RBC (human red blood cells).[1]
