Biological screening combined with the synthesis of heterocyclic compounds with numerous functions is the most effective approach available for pharmacological assessment of potential future medications. In the under taken research that is presented here, 4-(1H-indol-3-yl)butanoic acid was sequentially converted into 4-(1H-indol-3-yl)butanoate, 4-(1H-indol-3-yl)butanohydrazide, and 5-[3-(1H-indol-3-yl)propyl]-1,2,4-triazole-2-thiol as a nucleophile. By treating aryl amines with 3-bromopropanoyl chloride in a series of parallel reactions, different electrophiles were created, leading to the formation of N-(aryl)-3-bromopropanamides.

The structures of these newly designed molecules were verified by IR, H-NMR, C-NMR, EI-MS and CHN analysis data. These molecules were screened against tyrosinase and their inhibitory activity explored that these 3-substituted-benzamides exhibit good to excellent potential, comparative to the standard.

In this study, heavy metal contamination in topsoil around Sahiwal coal fired power plant (SCFPP) was investigated. Within distance of 0-10, 11-20, 21-30 and 31-40 km of SCFPP, total 56 soil samples were taken, 14 replicate from each distance along with a background subsurface soil sample beyond 60 km.

It is widely believed that an inhibitor of the LOX pathway represents a rational approach for designing more potent antiinflammatory leads with druggable super safety profiles. In our continual efforts in search for anti-LOX molecules, the present work was to design a new series of N-alkyl/aralkyl/aryl derivatives (7a-o) of 4-phenyl-5-(1-phenylcarbamoylpiperidine)-4H-1,2,4-triazole-3-thiol which was commenced in seriate formation of phenylcarbamoyl derivative (1), hydrazide (2), semicarbazide (3) and 4-phenyl-5-(1-phenylcarbamoylpiperidine)-4H-1,2,4-triazole-3-thiol (4).

The in vitro results established all the three compounds as potent tyrosinase inhibitors relative to the standard. The Kinetics mechanism plots established that compound 8 inhibited the enzyme non-competitively.
