3H-1,2-benzoxathiepine 2,2-dioxides: a new class of isoform-selective carbonic anhydrase inhibitors
Abstract A new chemotype with carbonic anhydrase (CA, EC 4.2.1.1) inhibitory action has been discovered, the homo-sulfocoumarins (3H-1,2-benzoxathiepine 2,2-dioxides) which have been designed considering the (sulfo)coumarins as lead molecules. An original synthetic strategy of a panel of such derivatives led to compounds with a unique inhibitory profile and very high selectivity for the inhibition of the tumour associated (CA IX/XII) over the cytosolic (CA I/II) isoforms. Although the CA inhibition mechanism with these new compounds is unknown for the moment, we hypothesize that it may be similar to that of the sulfocoumarins, i.e. hydrolysis to the corresponding sulfonic acids which therea…
Crystallographic Study of Solvates and Solvate Hydrates of an Antibacterial Furazidin
In this study we present a detailed crystallographic analysis of multiple solvates of an antibacterial furazidin. Solvate formation of furazidin was investigated by crystallizing it from pure solvents and solvent-water mixtures. Crystal structure analysis of the obtained solvates and computational calculations were used to rationalize the main factors leading to the intermolecular interactions present in the solvate crystal structures as well as resulting in formation of the observed solvates and solvate hydrates. Furazidin forms pure solvates and solvate hydrates with solvents having large hydrogen bond acceptor propensity as well as with a hydrogen bond donor and acceptor formic acid. In …
