A series of phthiobuzone analogs, prepared from potassium phthalimide or phthalandione, have been evaluated for their antiviral activities. Among the candidates, compounds 5j and 5k, which contain the substituted 4-halogenated phenyl ring at N-4′,4″ position, show more potent antiviral activity than phthiobuzone against herpes simplex virus 1 (IC50=8.56 and 2.85 μg/ml, respectively) and herpes simplex virus 2 (IC50=1.75 and 4.11 μg/ml, respectively). Compounds 9c and 9d with a propylene linker between the phthalimide and bisthiosemicarbazone moieties display similar antiviral potency against herpes simplex virus 1 (IC50=2.85 and 4.11 μg/ml, respectively).

There is disclosed the use of a compound of formula (I) wherein X, Y, W and Q are as defined in the specification, and pharmaceutically acceptable salts thereof, in the manufacture of a medicament, for the treatment or prophylaxis of diseases or conditions in which inhibition of the enzyme myeloperoxidase (MPO) is beneficial. Certain novel compounds of formula (I) and pharmaceutically acceptable salts thereof are disclosed, together with processes for their preparation. The compounds of formulae (I) are MPO inhibitors and are thereby particularly useful in the treatment or prophylaxis of neuroinflammatory disorders.

proton-coupled anion transporters with pH-switchable behaviour known to be regulated by an imine protonation equilibrium. Previously, chloride/nitrate exchange by PTSCs was found to be inactive at pH 7.2 due to locking of the thiourea anion binding site by an intramolecular hydrogen bond, and switched ON upon imine protonation at pH 4.5. The rate-determining process of the pH switch, however, was not
in vitro against ureaseenzyme to elucidate their anti-urease activity. All the compounds displayed potent inhibitory potential with IC50 values ranging between 3.65 ± 2.64 to 31.9 ± 1.094 μM, under positive control of thiourea (IC50 = 20.8 ± 0.75 μM). Structural activityrelationship (SAR) has revealed a variation based on substituents pattern at R group. The results of docking study suggest that these
