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

bidentate ligands to metal centres whilst retaining on their periphery a range of groups capable of forming triple hydrogen bonds. Their metalcomplexes have the potential to display interesting magnetic, optical and electrochemicalproperties when the hydrogen bonds are used for the crystal engineering of solid state materials. Here we report the synthesis and characterization of the six closely related

A simple, economical, and green approach to the synthesis of rhodanine derivatives using a tandem aldol condensation-thia-Michael addition process in aqueous diethylamine medium was described. The experiment protocol features simple operations, and the products were isolated in high to excellent yields (82–96%). As spontaneous precipitation always occurs at the end of the process, this leads to easy separation of the products via a simple filtration.

An efficient microwave-assisted synthesis of new (Z)-5-arylidenerhodanines under solvent-free conditions is described and their in vitro antifungal activity was evaluated following the CLSI (formerly NCCLS) guidelines against a panel of both standardized and clinical opportunistic pathogenic fungi. An analysis of the structure-activity relationship (SAR) along with computational studies showed that the most active compounds (F- and CF3-substituted rbodanines) possess high log P values and low polarizability. Mechanism-based assays suggest that active compounds neither would bind to ergosterol nor would produce a damage to the fungal membrane. (c) 2006 Elsevier Ltd. All rights reserved.
