Abstract:
In this study, thirteen new compounds having a 2-[1-(6-methoxy-2-naphthyl)ethyl]-6-(substituted)benzylidenethiazolo[3,2-b]- 1,2,4-triazole-5(6H)-one structure were synthesised using N-[2-(6-methoxy-2-naphthyl)propanoyloxysuccinimide, N-[2-(6-methoxy-2-naphthyl)propanoyl]thiosemicarbazide and 3-[1-(6-methoxy-2-naphthyl)ethyl]-5-mercapto-1,2,4-triazole. The structures and physical properties of the compounds were elucidated by IR, 1H NMR, mass spectroscopy and elemental analysis. The antiinflammatory activity and gastric ulceration potential of the compounds were tested using naproxen as a reference compound.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
