Leinamycin is an 18-membered macrolactam produced by several species of Streptomyces atroolivaceus. This macrolactam has also been shown to exhibit antitumor properties as well as antimicrobial properties against gram-positive and gram-negative bacteria.^[1] The presence of a spiro-fused 1,3-dioxo-1,2-dithiolane moiety was a unique structural property at the time of this compound's discovery and it plays an important role in leinamycin's antitumor and antibacterial properties due to its ability to inhibit DNA synthesis.^[2]^[3]
