[Image] [Image] ACTIVITY : Analgesic; Antimigraine; Neuroprotective; Nootropic; Antiparkinsonian; Anticonvulsant; Eating-Disorders-Gen.; Anabolic; Anorectic; Ophthalmological; Neuroleptic; Antidiabetic; Antidepressant; Anesthetic; Antiemetic; Antiaddictive; Respiratory-Gen.; Laxative. MECHANISM OF ACTION : Vesicular glutamate transporter 1 modulator; Vesicular glutamate transporter 2 modulator. The ability of (I) to inhibit vesicular glutamate transporter 1 was tested in rats. The results showed that 2-(3-(2-carboxy-5-nitrophenylcarbamoyl)benzamido)-4-nitrobenzoic acid exhibited an inhibitory activity of 92%.
