2-Thiohydantoin derivatives are produced by heating a mixture of thiourea and an α-amino acid. The method described offers the advantages of simplicity, low cost, easy work-up and scalability.

by reaction of L-amino acids with thiourea or ammonium thiocyanate. Their antimicrobial activities were evaluated against bacterial strains by broth microdilution assays. The time-kill kinetics, the antibiofilm activity and the cytotoxicity to mammalian cells were determined for the compound that exhibited the best antimicrobial profile (1b). Results: Eleven thiohydantoins were readily obtained in good

campaigns, we decided to perform a systematic study on their promiscuity. An amount of 163 rhodanines, hydantoins, thiohydantoins, and thiazolidinediones were synthesized and tested against several targets. The compounds were also characterized with respect to aggregation and electrophilic reactivity, and the binding modes of rhodanines and relatedcompounds in published X-ray cocrystal structures were analyzed
