Exploring a new family of designer copper(II) complexes of anthracene-appended polyfunctional organic assembly displaying potential anticancer activity via cytochrome c mediated mitochondrial apoptotic pathway. J Inorg Biochem 2023; 243:112182. [PMID: 36933342 DOI: 10.1016/j.jinorgbio.2023.112182] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 02/27/2023] [Accepted: 03/08/2023] [Indexed: 03/18/2023]
Abstract
The present article describes the systematic study on design and synthesis, physicochemical properties and spectroscopic features, and potential anticancer activities of a family of novel copper(II)-based designer metal complexes [Cu2(acdp)(μ-Cl)(H2O)2] (1), [Cu2(acdp)(μ-NO3)(H2O)2] (2) and [Cu2(acdp)(μ-O2CCF3)(H2O)2] (3) of anthracene-appended polyfunctional organic assembly, H3acdp (H3acdp = N,N'-bis[anthracene-2-ylmethyl]-N,N'-bis[carboxymethyl]-1,3-diaminopropan-2-ol). Synthesis of 1-3 was accomplished under facile experimental conditions, preserving their overall integrity in solution. The incorporation of polycyclic anthracene skeleton within the backbone of organic assembly increases lipophilicity of resulting complexes, thereby dictating the degree of cellular uptake with improved biological activity. Complexes 1-3 were characterized by elemental analysis, molar conductance, FTIR, UV-Vis absorption/fluorescence emission titration spectroscopy, PXRD and TGA/DTA studies, including DFT calculations. The cellular cytotoxicity of 1-3 when studied in HepG2 cancer cell line showed substantial cytotoxic effects, whereas no such cytotoxicity was observed when exposed to normal L6 skeletal muscle cell line. Thereafter, the signaling factors involved in the process of cytotoxicity in HepG2 cancer cells were investigated. Alteration of cytochrome c and Bcl-2 protein expression levels along with modulation of mitochondrial membrane potential (MMP) in the presence of 1-3, strongly suggested the possibility of activating mitochondria-mediated apoptotic pathway involved in halting the cancer cell propagation. However, when a comparative assessment on their bio-efficacies was made, 1 showed higher cytotoxicity, nuclear condensation, DNA binding and damage, ROS generation and lower rate of cell proliferation compared to 2 and 3 in HepG2 cell line, indicating that the anticancer activity of 1 is significantly higher than that of 2 and 3.

Abstract
D-allulose is a high-value rare sugar with many health benefits. D-allulose market demand increased dramatically after approved as generally recognized as safe (GRAS). The current studies are predominantly focusing on producing D-allulose from either D-glucose or D-fructose, which may compete foods against human. The corn stalk (CS) is one of the main agricultural waste biomass in the worldwide. Bioconversion is one of the promising approach to CS valorization, which is of significance for both food safety and reducing carbon emission. In this study, we tried to explore a non-food based route by integrating CS hydrolysis with D-allulose production. Firstly we developed an efficient Escherichia coli whole-cell catalyst to produce D-allulose from D-glucose. Next we hydrolyzed CS and achieved D-allulose production from the CS hydrolysate. Finally we immobilized the whole-cell catalyst by designing a microfluidic device. Process optimization improved D-allulose titer by 8.61 times, reaching 8.78 g/L from CS hydrolysate. With this method, 1 kg CS was finally converted to 48.87 g D-allulose. This study validated the feasibility of valorizing corn stalk by converting it to D-allulose.

Abstract
Chrysin is a flavone found in many plant extracts including blue passion flower, propolis and honey. The magnesium(ii) cation is an essential metal for life and it is involved in a variety of metabolic and physiological functions. Biological activities of flavonoids can be improved by complexation with metals. For this reason, Mgchrys was synthesised. The complex was characterised by spectroscopic techniques (ultraviolet–visible absorption spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), 1H and 13C-NMR) and elemental and thermogravimetric analysis. The results indicated that chrysin reacts with magnesium(ii) through a 4-carbonyl-5-hydroxy chelation site. The computational study suggests the coexistence of at least twelve conformers of Mgchrys at room temperature. There are six most stable conformers that show square-pyramidal and distorted square-pyramidal geometries. In addition, anticancer and antimetastatic activities of Mgchrys on the A549 cell line were evaluated and compared with the metal and the free ligand. The complex did not show cytotoxicity against normal lung fibroblasts but it behaved as a cytotoxic drug against the cancer cell line with oxidative stress being its probable mechanism of action. However, Mgchrys inhibited the different steps involved in the metastatic cascade: adhesion to fibronectin, migration and invasion. The compounds displayed no acute toxicity (Artemia salina test) and no mutagenic effect (Ames test).
