GML-1 is a TSPO (peripheral benzodiazepine receptor) ligand with anxiolytic activity. Its binding affinity (Ki value) to TSPO is comparable with PK11195. GML-1 is selective for TSPO versus the central benzodiazepine receptor (CBR, GABAA receptor). The compound GML-1 was the most active of a series of 1-arylpyrrolopyrazine-3-carboxamides, and its anxiolytic effects were examined using the open field test (OFT) and the elevated plus maze (EPM) test. The EPM test is a general anxiety test measuring the time spent by animals in the open or the enclosed arms. When compound was administered to CD-1 mice at the dose of 1.0 mg/kg, it significantly increased the percentage of open arm entries and the time spent in the open arms. GML-1 is a potential antianxiety agent.

The TSPO-mechanism of anxiolytic action of GML-1 was proved by inhibitor analysis with TSPO antagonist PK11195 that blocks effect of GML-1.

The involvement of neurosteroids in the mechanism of action of GML-1 was confirmed by co-administration of GML-1 with neurosteroid synthesis inhibitors. The anxiolytic effect of GML-1 in elevated plus-maze tests was completely blocked by the neurosteroidogenic-enzyme inhibitors trilostane and finasteride.

The tablet dosage form of GML-1 was developed and showed pronounced anxiolytic activity after intragastric administration in rats in a wide range of doses.
