- A new series of N-substituted phthalimide compounds was synthesized in good yield. All the compounds were characterized by spectroscopic data and were evaluated for their inhibitory activity against the expression of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) and pro-inflammatory proteins in the bacterial lipopolysaccharide (LPS)-induced murine macrophage (RAW 264.7) cells. All the compounds significantly (p <0.05) downregulated the LPS-stimulated COX-2 and iNOS expression from 100% to the ranges of 61.9±5.1–84.5±4.1% and 41.1±5.4–85.3±1.9%) at 10 µM, respectively. Among others, 4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N′-[(3,4-dichlorophenyl)methylidene]benzohydrazide displayed the most potent inhibition to the level of (41.1±5.4%) iNOS expression, about half of the potency of dexamethasone (23.0±3.3%). Moreover, the neuroprotective activity of the compounds was assessed against the 6-hydroxydopamine (6-OHDA)-challenged neuroblastoma SH-ST5Y cells, and all compounds exhibited significant (p <0.05) protection with variable potencies. 4-(1,3-Dioxo-1,3-dihydro-2H-isoindol-2-yl)-N′-[(3,4-dihydroxyphenyl)methylidene]benzohydrazide was found to display more than 70% relative neuroprotection against 6-OHDA-induced cell death with the additional advantage of keeping the highest cell viability index (83.3±4.5%) to the cells.
