Simple and efficient method for aromatization of tetrahydro-β-carbolines by using K2S2O8 as a catalyst and its antimicrobial activity comparison with molecular docking studies

详细

A novel and efficient aromatization of tetrahydro-β-carbolines under mild conditions using K₂S₂O₈ as a catalyst was developed. The method is applicable for all kinds of C¹ substituted systems. All synthesized compounds were screened for their in vitro antibacterial activity against Staphylococus aureus, Bacillus subtilis, Escherichia coli, and Klebsiella pneumonia, as well as fungi, such as Aspergillus flavus and Fusarium oxysporum. Compounds 4b, 4g, 4i, and 4k demonstrated excellent in vitro antibacterial and antifungal activities than the standard drugs. The docking studies were carried out for most active compounds 4b, 4g, 4i, and 4k.
