Design, synthesis and inhibitory activity of novel 2, 3-dihydroquinolin-4(1H)-one derivatives as potential succinate dehydrogenase inhibitors. Eur J Med Chem 2021; 214:113246. [PMID: 33582385 DOI: 10.1016/j.ejmech.2021.113246] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 01/25/2021] [Accepted: 01/26/2021] [Indexed: 11/23/2022]
Abstract
Thirty-three new 2, 3-dihydroquinolin-4(1H)-one analogues were designed, synthesized and characterized by IR, 1H NMR, 13C NMR and HRMS. The crystal structures of compounds 2g and 4l were characterized by single crystal X-ray diffraction. Their antifungal activities were determined against five plant pathogenic fungi namely Rhizoctonia solani, Fusarum graminearum, Helminthosporium maydis, Sclerotinia sclerotiorum and Botrytis cinerea. The results indicated that most of them revealed significant antifungal activity at 20 mg/L. Compound 4e showed the strongest antifungal activity against Botrytis cinerea and had better effects than the commercial fungicide fluopyram. Meanwhile, the active compounds were evaluated for their inhibitory activities against succinate dehydrogenase (SDH). The results displayed that they exhibited excellent activity. Compound 4e had better inhibitory activity than fluopyram. The molecular modeling results demonstrated that compound 4e could strongly bind to and interact with the binding sites of SDH. The inhibitory activity of 2, 3-dihydroquinolin-4(1H)-one derivatives against SDH has been reported for the first time.

Abstract
Fungal infections are a growing challenge in immunocompromised patients, especially candidiasis. The prolonged use of traditional antifungals to treat Candida infection has caused the emergence of drug resistance, especially fluconazole. Therefore, new therapeutic strategies for Candida infection are warranted. Recently, attention has been paid to the anti-Candida activity of antibiotics and their derivatives. Studies revealed that a series of antibiotics/derivatives displayed potential anti-Candida activity and some of them could significantly increase the susceptibility of antifungals. Interestingly, the derivatives of aminoglycosides were even more active than fluconazole/itraconazole/posaconazole. This article reviews the anti-Candida activities and mechanisms of antibiotics/derivatives used alone or in combination with antifungals. This review will helpfully provide novel insights for overcoming Candida resistance and discovering new antifungals.

Abstract
Globally, invasive fungal infections pose a significant challenge to modern human medicine due to the limited number of antifungal drugs and the rise in resistance to current antifungal agents. A vast majority of invasive fungal infections are caused by species of Candida, Cryptococcus, and Aspergillus. Novel antifungal molecules consisting of unexploited chemical scaffolds with a unique mechanism are a pressing need. The present study identifies a dibromoquinoline compound (4b) with broad-spectrum antifungal activity that inhibits the growth of pertinent species of Candida (chiefly C. albicans), Cryptococcus, and Aspergillus at a concentration of as low as 0.5 μg/mL. Furthermore, 4b, at a subinhibitory concentration, interfered with the expression of two key virulence factors (hyphae and biofilm formation) involved in C. albicans pathogenesis. Three yeast deletion strains ( cox17Δ, ssa1Δ, and aft2Δ) related to metal ion homeostasis were found to be highly sensitive to 4b in growth assays, indicating that the compound exerts its antifungal effect through a unique, previously unexploited mechanism. Supplementing the media with either copper or iron ions reversed the strain sensitivity to 4b, further corroborating that the compound targets metal ion homeostasis. 4b's potent antifungal activity was validated in vivo, as the compound enhanced the survival of Caenorhabditis elegans infected with fluconazole-resistant C. albicans. The present study indicates that 4b warrants further investigation as a novel antifungal agent.

Abstract
Gram-positive bacteria are responsible for a broad range of infectious diseases, and the emergency and wide spread of drug-resistant Gram-positive pathogens including MRSA and MRSE has caused great concern throughout the world. 4-Quinolones which are exemplified by fluoroquinolones are mainstays of chemotherapy against various bacterial infections including Gram-positive pathogen infections, and their value and role in the treatment of bacterial infections continues to expand. However, the resistance of Gram-positive organisms to 4-quinolones develops rapidly and spreads widely, making them more and more ineffective. To overcome the resistance and reduce the toxicity, numerous of 4-quinolone derivatives were synthesized and screened for their in vitro and in vivo activities against Gram-positive pathogens, and some of them exhibited excellent potency. This review aims to outlines the recent advances made towards the discovery of 4-quinolone-based derivatives as anti-Gram-positive pathogens agents and the critical aspects of design as well as the structure-activity relationship of these derivatives. The enriched SAR paves the way to the further rational development of 4-quinolones with a unique mechanism of action different from that of the currently used drugs to overcome the resistance, well-tolerated and low toxic profiles.

Abstract
Based on a rationally conceived pharmacophore model to build a multi-target bacterial topoisomerase inhibitor, twenty-one fluoroquinolone-flavonoid hybrids were synthesized. Some obtained hybrids show excellent antibacterial activity against drug-resistant microorganisms with narigenin-ciprofloxacin being the most active, showing 8, 43, 23 and 88 times better activity than ciprofloxacin against Escherichia coli ATCC 35218, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923 and Candida albicans ATCC 90873, respectively. Drug accumulation and DNA supercoiling assays of two active analogues revealed potent inhibition of both the DNA gyrase and efflux pump, confirming the desired dual mode of action. Molecular docking study disclosed that the introduced flavonoid moiety not only provides several additional interactions but also does not disturb the binding mode of the floxacin moiety. Our data also demonstrated that development of antifungals is possible from fluoroquinolones modified at C-7 position.
