Food Chem 2024; 459:140347. [PMID: 38991436 DOI: 10.1016/j.foodchem.2024.140347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 06/26/2024] [Accepted: 07/03/2024] [Indexed: 07/13/2024]
Abstract
Quercetin is a flavonoid that occurs in many types of fruit and vegetables and is stable for no longer than 4.5 h in the investigated pH range (6.0-8.0), even at 4 °C in the dark. At higher temperatures, the degradation/oxidation process is much faster. Simple but effective proliposomal encapsulation was used to protect the quercetin from environmental conditions such as pH. With this approach, 65 to 90% of pure quercetin and quercetin-rich onion extract was kept after >60 days under conditions that favoured its oxidation (pH 7.4). In addition, the encapsulated quercetin decreases the lipid peroxidation induced by pulsed UV light by >50%. At a mass ratio of 1:100 quercetin to lipids (w/w), the liposomes remained intact in solutions for six months. Quercetin in lipid bilayers simultaneously protects the unsaturated lipids from peroxidation.

Ansari MF, Arjmand F. Quercetin-phenylalanine 3d-transition metal-based {Co(II), Ni(II) & Cu(II)} intercalative therapeutic agents: DNA & BSA interaction studies in vitro and cleavage activity. Int J Biol Macromol 2024; 254:127521. [PMID: 37898256 DOI: 10.1016/j.ijbiomac.2023.127521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 10/02/2023] [Accepted: 10/09/2023] [Indexed: 10/30/2023]
Abstract
New Quercetin-phenylalanine metal-based therapeutic agents of the formulation [Qu(Phe)M(II).(H2O)2].NO3 where M(II) = Co(II) and Ni(II) and [Qu(Phe)Cu(II).(H2O)2] were synthesized and their structure was predicted by IR, UV-vis, EPR and ESI-MS spectroscopic techniques. The bio-molecular interaction studies of the Quercetin-phenylalanine complexes, 1-3 with ct-DNA and BSA were performed using a battery of complimentary biophysical techniques. The corroborative results of these experiments revealed strong binding propensity via electrostatic interactions probably through minor grove binding towards ct-DNA, therapeutic target. The binding affinity of Quercetin-phenylalanine complexes 1-3 was quantified by determining binding constants values, Kb, Ksv, and the magnitude of binding propensity followed the order 3 > 1 > 2, implicating the preferential binding of Cu(II) complex 3 with ct-DNA. The cleavage studies were performed with complexes using gel electrophoretic mobility assay. The complexes 1-3 demonstrated efficient cleaving ability by the hydrolytic cleavage pathway involving hydroxyl (OH) radicals. BSA binding profile of Quercetin-phenylalanine metal therapeutics 1-3 was studied in order to understand the drug carrier potential of these compounds and found that complex 3 was capable of binding preferentially with BSA as compared to other complexes.

Abstract
Quercetin is one of the most powerful bioactive dietary flavonoids. The in vivo biological study of quercetin is extremely difficult due to its very low solubility. However, diorganotin complexes of quercetin are more useful when contrasted with quercetin due to increased solubility. In the present study, quercetin, substituted biguanide synthesized in the form of Schiff base and its di-alkyl/aryl tin (IV) complexes were obtained by condensing Schiff base with respective di-alkyl/aryl tin (IV) dichloride. Advanced analytical techniques were used for structural elucidation. The results of biological screening against Gram-positive/Gram-negative bacteria and fungi showed that these diorganotin (IV) derivatives act as potent antimicrobial agents. The in silico investigation with dihydropteroate (DHPS) disclosed a large ligand-receptor interaction and revealed a strong relationship between the natural exercises and computational molecular docking results.

Abstract
The term "scavengome" refers to the chemical space of all the metabolites that may be formed from an antioxidant upon scavenging reactive oxygen or nitrogen species (ROS/RNS). This chemical space covers a wide variety of free radical metabolites with drug discovery potential. It is very rich in structures representing an increased chemical complexity as compared to the parent antioxidant: a wide range of unusual heterocyclic structures, new CC bonds, etc. may be formed. Further, in a biological environment, this increased chemical complexity is directly translated from the localized conditions of oxidative stress that determines the amounts and types of ROS/RNS present. Biomimetic oxidative chemistry provides an excellent tool to model chemical reactions between antioxidants and ROS/RNS. In this chapter, we provide an overview on the known metabolites obtained by biomimetic oxidation of a few selected natural antioxidants, i.e., a stilbene (resveratrol), a pair of hydroxycinnamates (caffeic acid and methyl caffeate), and a flavonol (quercetin), and discuss the drug discovery perspectives of the related chemical space.

Abstract
Interest in antimicrobial gold complexes originated from the work of Robert Koch at the end of 19th century, who demonstrated that potassium dicyanidoaurate(I), K[Au(CN)2], showed activity against Mycobacterium tuberculosis, a causative agent of tuberculosis. Subsequently, a large number of gold(I) and gold(III) complexes have been evaluated as possible antimicrobial agents against a broad spectrum of bacteria, fungi and parasites. The first part of the present review article summarizes the results achieved in the field of antibacterial and antifungal activity of gold(I) and gold(III) complexes. The represented gold(I) complexes have been divided into three distinct classes based on the type of coordinated ligand: (i) complexes with phosphine-type ligands, (ii) complexes with N-heterocyclic carbene ligands and (iii) various other gold(I) complexes, while the results related to the antibacterial and antifungal gold(III) complexes have been mainly focused on the organometallic-type of complexes. The second section of this article represents findings obtained from the evaluation of antimalarial activity of gold complexes against chloroquine-sensitive and chloroquine-resistant strains of Plasmodium falciparum parasite. Antimalarial gold(I) and gold(III) complexes have been divided into the following classes, based on the nature of the coordinated ligand: (i) complexes with chloroquine and its derivatives, (ii) complexes with N-heterocyclic carbene ligands, (iii) complexes containing functionalised alkynes and (iv) thiosemicarbazonato ligands, as well as (v) other gold(I) and gold(III) complexes. In the last section of the review, gold(I) and gold(III) complexes have been reported to be potential agents against parasites that cause amoebiasis, leishmaniasis and trypanosomiasis. A systematic summary of these results could contribute to the future design of new gold(I) and gold(III) complexes as potential antimicrobial agents.
