Structure-Activity Relationship of Natural Dihydrochalcones and Chalcones, and Their Respective Oxyalkylated Derivatives as Anti- Saprolegnia Agents. PLANTS (BASEL, SWITZERLAND) 2024; 13:1976. [PMID: 39065502 PMCID: PMC11281103 DOI: 10.3390/plants13141976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2024] [Revised: 07/17/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024]
Abstract
Saprolegnia sp. is a pathogenic oomycete responsible for severe economic losses in aquaculture. To date, there is no treatment for its control that is effective and does not pose a threat to the environment and human health. In this research, two dihydrochalcones 1 and 2, and three chalcones 3-5, isolated from the resinous plant Adesmia balsamica, as well as their synthesized oxyalkylated derivatives 6-29 already reported and a new synthesized series of oxyalkylchalcones 30-35, were evaluated for their anti-saprolegnia activity and structure-activity relationship as potential control and treatment agents for strains of Saprolegnia parasitica and S. australis. Among the molecules tested, natural 2',4'-dihydroxychalcone (3) and new oxyalkylchalcone 34 were the most potent antisaprolegnia agents against both strains, even with better results than the commercial control bronopol. On the other hand, the structure-activity relationship study indicates that the contributions of steric and electrostatic fields are important to enhance the activity of the compounds, thus the presence of bulky substituents favors the activity.

Abstract
Despite the notable advancements made over the past decade in achieving carbon-carbon bonds by transition-metal-catalyzed cross-coupling processes, metal-free cross-coupling reactions for hydroacylation of aromatic alkynes via C(sp3)-H functionalization are still rare and highly desired. Here we report a metal-free reliable approach for the synthesis of α,β-unsaturated ketones (chalcones) via C(sp3)-H functionalization using MeCN:H2O as green solvent, Eosin Y as organic photocatalyst, and ambient air as oxidant. More significantly, this strategy can effectively transform a variety of methyl arenes and aromatic alkynes into the desired product. With high atom efficiency, use of green solvents, metal-free nature, environmental friendliness, and visible light as a renewable energy source, this method is compatible with biologically active molecules.

Abstract
Chalcone derivatives are considered valuable species because they possess a ketoethylenic moiety, CO-CH=CH-. Due to the presence of a reactive α,β-unsaturated carbonyl group, chalcones and their derivatives possess a wide spectrum of antiproliferative, antifungal, antibacterial, antiviral, antileishmanial, and antimalarial pharmacological properties. Recent developments in heterocyclic chemistry have led to the synthesis of chalcone derivatives, which had been biologically investigated toward certain disease targets. The major aspect of this review is to present the most recent synthesis of chalcones bearing N, O, and/or S heterocycles, revealing their biological potential during the past decade (2010-2021). Based on a review of the literature, many chalcone-heterocycle hybrids appear to exhibit promise as future drug candidates owing to their similar or superior activities compared to those of the standards. Thus, this review may prove to be beneficial for the development and design of new potent therapeutic drugs based on previously developed strategies.

Novel sulfonamide-chalcone hybrid stimulates inflammation, angiogenesis and upregulates vascular endothelial growth factor (VEGF) in vivo. Microvasc Res 2022; 139:104253. [PMID: 34520773 DOI: 10.1016/j.mvr.2021.104253] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 07/30/2021] [Accepted: 09/06/2021] [Indexed: 01/20/2023]
Abstract
Chalcones and sulfonamides are well-known chemical groups associated with several biological activities such as antibiotic, anti-inflammatory, and antitumor activities. Over the past few decades, a series of sulfonamide-chalcone hybrids have been synthesized and assessed to develop compounds with interesting biological properties for application in disease therapy. In the present study, a new sulfonamide-chalcone hybrid μ - (2,5-dichloro-N-{4-[(3E)-4-(3-nitrophenyl) buta-1,3-dien-2-yl] phenyl} benzene sulfonamide), or simply CL185, was synthesized, and its angiogenic activity was assessed using the chick embryo chorioallantoic membrane (CAM) assay at different concentrations (12.5, 25, and 50 μg/μL). To further investigate the role of CL185 in the angiogenic process, we evaluated the levels of vascular endothelial growth factor (VEGF) in all treated CAMs. The results showed that all concentrations of CL185 significantly increased tissue vascularization (p < 0.05) as well as the parameters associated with angiogenesis, in which inflammation was the most marked phenomenon observed. In all CAMs treated with CL185, VEGF levels were significantly higher than those in the negative control (p < 0.05), and at the highest concentration, VEGF levels were even higher than in the positive control (p < 0.05). The pronounced angiogenic activity displayed by CL185 may be related to the increase in VEGF levels that were stimulated by inflammatory processes observed in our study. Therefore, CL185 presents a favorable profile for the development of drugs that can be used in pro-angiogenic and tissue repair therapies.

Abstract
Chalcones belong to the flavonoid class of phenolic compounds. They form one of the largest groups of bioactive natural products. The potential anticancer, anti-inflammatory, antimicrobial, antioxidant, and antiparasitic properties of naturally occurring chalcones, and their unique chemical structural features inspired the synthesis of numerous chalcone derivatives. In fact, structural features of chalcones are easy to construct from simple aromatic compounds, and it is convenient to perform structural modifications to generate functionalized chalcone derivatives. Many of these synthetic analogs were shown to possess similar bioactivities as their natural counterparts, but often with an enhanced potency and reduced toxicity. This review article aims to demonstrate how bioinspired synthesis of chalcone derivatives can potentially introduce a new chemical space for exploitation for new drug discovery, justifying the title of this article. However, the focus remains on critical appraisal of synthesized chalcones and their derivatives for their bioactivities, linking to their interactions at the biomolecular level where appropriate, and revealing their possible mechanisms of action.
