Development of Novel Substituted 1,2,3,4-tetrahydro Cyclohex-1,2,3-trihydro Cyclopenta [B] Indole Derivatives as Potential Therapeutic Agents

Abstract

The current study aims to synthesize, characterize, and evaluate a specific class of heterocyclic compounds called fused polycyclic indoles, in combination with carbazoles, carbolines, and their partially saturated counterparts. These compounds have been known to have potent biological activity. The study's procedures involve synthesizing these compounds and evaluating them for central nervous system activity. Results showed that all the compounds had CNS-depressing effects in mice. Some compounds, such as YA1 and YA5, were found to have a stronger CNS-depressing activity than others. All compounds tested, YA1 to YA7, caused more than 50% change in locomotor activity when compared to a standard drug. YA3 and YA5 were found to have the highest activity at 86.2% and 83.9% respectively after 120 minutes of administration at a dose of 100 mg/kg. In addition, the acute oral toxicity studies showed that YA3 was non-toxic and YA5 was found to be toxic. The findings of the study provide evidence that these title compounds have good CNS activity.
