Structure–Activity Relationship of Benzofuran Derivatives with Potential Anticancer Activity

Abstract

Benzofuran is a heterocyclic compound found naturally in plants and it can also be obtained through synthetic reactions. Multiple physicochemical characteristics and versatile features distinguish benzofuran, and its chemical structure is composed of fused benzene and furan rings. Benzofuran derivatives are essential compounds that hold vital biological activities to design novel therapies with enhanced efficacy compared to conventional treatments. Therefore, medicinal chemists used its core to synthesize new derivatives that can be applied to a variety of disorders. Benzofuran exhibited potential effectiveness in chronic diseases such as hypertension, neurodegenerative and oxidative conditions, and dyslipidemia. In acute infections, benzofuran revealed anti-infective properties against microorganisms like viruses, bacteria, and parasites. In recent years, the complex nature and the number of acquired or resistant cancer cases have been largely increasing. Benzofuran derivatives revealed potential anticancer activity with lower incidence or severity of adverse events normally encountered during chemotherapeutic treatments. This review discusses the structure–activity relationship (SAR) of several benzofuran derivatives in order to elucidate the possible substitution alternatives and structural requirements for a highly potent and selective anticancer activity.

Could natural terpenes be an alternative for the treatment of neglected tropical diseases?

“…The antiparasitic properties of compound 3 can be attributed to the presence of a benzofurane ring. The benzofuran ring is known to enhance the biological activity of various compounds (Farhat et al., 2022). This compound also exhibits biological activity against larvae of Anopheles subpictus , a malaria vector (Govindarajan et al., 2018), and Eimeria oocysts, causing avian coccidiosis (Massoud et al., 2010).…”

Fluorescence in depth: integration of spectroscopy and imaging with Raman, IR, and CD for advanced research

“…The combined CD and fluorescence spectroscopies have applications in drug delivery studies. Benzofuran derivatives have promising potential as anticancer agents, demonstrating a lower occurrence and severity of adverse effects commonly observed during chemotherapy treatments [196]. To probe their ability to interact with proteins, Scognamiglio et al assessed the interaction of two 4-nitrophenyl-functionalized benzofurans (BF1 and BDF1) with bovine serum albumin (BSA), which served as a model protein.…”

Synthesis of 2-acyl benzofurans and indoles based on nucleophile-intercepted Meyer–Schuster rearrangement of o-hydroxyphenyl and o-aminophenyl propargylic alcohols

“…Benzoheterocycles such as benzofurans and indoles have been demonstrated to be privileged structures widely found in drugs, bioactive natural products, agrochemicals, and functional materials. 1 Among them, 2-aroyl benzofurans and indoles have attracted increasing attention in recent decades due to their important activities as promising drug candidates. 2 For example, rugchalcone A–B ( 1 and 2 ) showed promising anti-inflammatory activity.…”
