In the present paper 5-[4′-(4-[(4-aryloxy)methyl]-1H-1,2,3-triazol-1-yl}methyl)[1,1′-biphenyl]-2-yl]-1H-tetrazoles (5a–g) and [2′-(1H-tetrazol-5-yl)[1,1′-biphenyl]-4-yl]methyl-substituted-1-carbodithioates (11h–q) have been designed and synthesized. These compounds were subjected to docking (against AT1 receptor protein enzyme in complex with Lisinopril), in vitro angiotensin converting enzyme inhibition

with carbondisulfide in the presence of bases. These compounds were tested for the inhibition of four human (h) isoforms of the zinc enzyme carbonic anhydrase, CA (EC 4.2.1.1), hCA I, II, IX, and XII, involved in pathologies such as glaucoma (CA II and XII) or cancer (CA IX). Several low nanomolar inhibitors targeting these CAs were detected. The X-ray crystalstructure of the hCA II adduct with morpholine

A carbonic anhydrase inhibitor which comprises a compound of general formula: R1R2N-CS2-M+ for use in the treatment of microbial infection, eye disease or cancer; wherein R1 and R2 are each independently selected from H or an organic substituent, or together form a ring, and optionally contain one or more heteroatoms; wherein R and R2 together comprise at least 5 carbon atoms or at least 2 carbon atoms and a heteroatom, or R2 comprises at least 4 carbon atoms; and wherein M+ comprises a monovalent cation.
Synthesis of <i>S</i>-(2-Thioxo-1,3-dithiolan-4-yl)methyl Dialkylcarbamothioate and <i>S</i>-Thiiran-2-ylmethyl Dialkylcarbamothioate via Intermolecular O−S Rearrangement in Water<sup>,</sup>
3-dithiolan-4-yl)methyl dialkylcarbamothioates (3) and S-thiiran-2-ylmethyl dialkylcarbamothioate (5) has been reported by the reaction of 5-(chloromethyl)-1,3-oxathiolane-2-thione (1) with sodium dialkylcarbamodithioate (2) and dialkylamine (4), respectively, through intermolecular O−S rearrangement in water. A plausible mechanism of formation of the title compounds has also been proposed.
Some thiazole derivatives bearing dithiocarbamic acid esters were synthesized in order to investigate their anticandidal activity and cytotoxicity. The structures of the obtained final compounds (6a--j) were confirmed by spectral data (IR, ^1H NMR, ^13}C NMR, and MS) and elemental analysis. The anticandidal activity of the compounds was determined (6a--j) using the microbroth dilution method and their cytotoxicity was evaluated according to the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay against normal cells. Contrary to expectations, weak antifungal activity was observed with IC_50} values ranging between 30 and 403 \mu g/mL.
