Benzopyrylium salts as new anticancer, antibacterial, and antioxidant agents.

ABSTRACT: Benzopyrylium salts are an unexplored class of compounds and as a first, this study reports them as potential therapeutic agents. In this effort we pursue the synthesis and in vitro anticancer, antibacterial and antioxidant properties of some novel benzopyrylium salts. The benzopyrylium salts were synthesized and further characterized via UV-vis, IR, ¹H-NMR, ¹³C-NMR and mass spectrometry. The benzopyrylium salts were tested in vitro for anticancer activity across NCI 60 cell line panel. PS-CP-4MO showed the best activity against the MDA-MB-435 cell line of melanoma cancer in terms of the least GI₅₀ (1.78 μM), TGI (3.47 μM) and LC₅₀ (6.77 μM) values and showed selectivity against melanoma, colon cancer and leukemia. Mechanistic studies indicate that this compound inhibits MCF-7 cancer cells by inducing apoptosis and abrogates colony formation and wound healing in the cancer cells. Antibacterial studies show that some of the benzopyrylium salts are active on S. aureus (ATCC 29213) and the best active compound PS-CP-5Cl has a MIC of 8 μg/mL. Antioxidant studies indicate that they have good free radical scavenging properties (PS-CP-5Cl showed activity 1.48 times ascorbic acid). Fulfillment of the Lipinski's parameters of the benzopyrylium salts in silico showed tremendous drug likeness as potential pharmacophore leads.
