The identity of the ortho-substituent of an arylazide influences its reactivity toward transition metals. Substitution of a vinyl group with an imine disables rhodium(II)-mediated C-H amination and triggers a Lewis acid mechanism catalyzed by iron(II) bromide to facilitate benzimidazole formation.
Eleven analogs of N-arylisoindoline pharmacophore were synthesized and evaluated for their anticonvulsant activities. The in vivo screening data acquired indicate that all the analogs have the ability to protect against pentylenetetrazole-induced seizure. Compounds 2, 6, and 11 elevated clonic seizure thresholds at 30 min which were more active than reference drug phenytoin, and compounds 2, 7, and 11 showed marked anticonvulsant activity on tonic seizure. The most potent compounds were 2 and 11 which had comparative activity to the phenytoin. Using a model of the open pore of the Na channel, we have docked all compounds. Docking studies have revealed that these compounds interacted mainly with residues II-S6 of NaV1.2 by making hydrogen bonds and have additional hydrophobic interactions with other domains in the channel's inner pore.

A series of related thalidomide derivatives (2-9) were synthesized by microwave irradiation and evaluated for anti-inflammatory activity. Such activity was assessed in vivo and ex vivo. Compounds 2, 8 and 9 showed the highest levels of inhibition of TNF-alpha production. On rat paw edema and hyperalgesia assays, compound 9, (1,4-phthalazinedione) demonstrated the highest in vivo anti-inflammatory activity
