In addition, two compounds (5a and 6a) were examined for their in vivo genotoxicity using rats and an 8-hydroxy-2'-deoxyguanosine (8-OHdG) assay. Compounds 5a and 5b were found to be highly active against Gram-positive and Gram-negative bacteria. In addition, a significant inhibition of urinary 8-OHdG level (50.2%) was observed upon treatment of animals with 500 mg/kg body weight (b.w.) of compound 6a (p < 0.0001). However, compound 5a increased urinary 8-OHdG levels. The lethal dose (LD₅₀) values for compounds 5a and 6a were determined by an up-and-down procedure (OECD 425; OECD 1998), which showed that these compounds are safe, since the LD₅₀ was >5000 mg/kg b.w. Thus, the tested compounds might have the potential for use as antibiotics, since they have low genotoxicity and strong antimicrobial activity.21:T7ed,
