Information. does cephalexin have any quinolones or derives from quinolones?

No.: Cephalexin is a an antibiotic in the cephalosporin family, with a mechanism of action similar to penicillins. It works by disrupting the synthesis of bacterial cell walls. Quinolones, like ciprofloxacin, are a different class of antibiotics, with a completely different structure and mechanism of action. These work by preventing dna unwinding. These classes are unrelated.
