[PMID: 37215785 PMCID: PMC10192847 DOI: 10.1016/j.heliyon.2023.e16108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 05/03/2023] [Accepted: 05/05/2023] [Indexed: 05/24/2023] Open
Abstract
Novel water-compatible supramolecular polymers (WCSP) based on the non-covalent interaction between carboxymethylcellulose (CMC) and o, m, and p-nitrophenylmaleimide isomers are proposed. The non-covalent supramolecular polymer was obtained from high viscosity CMC with a degree of substitution 1.03 with o, m, and p-nitrophenylmaleimide molecules that were synthesized from maleic anhydride and its corresponding nitroaniline. Subsequently, blends were made at different nitrophenylmaleimide concentrations, stirring rate, and temperatures, with 1.5% CMC, to select the best conditions for each case and to evaluate the rheological properties. The selected blends were used to form films and analyze spectroscopic, physicochemical, and biological properties. Then, the interaction between a CMC monomer and each isomer of nitrophenylmaleimide was investigated using quantum chemistry computational calculations with the B3LYP/6-311 + G (d,p) method, providing a detailed explanation of their intermolecular interactions. The supramolecular polymers obtained exhibit an increase in viscosity of blends between 20% and 30% compared to CMC, a shift in the wavenumber of the OH infrared band by approximately 66 cm-1, and the first decomposition peak at the glass transition temperature occurring between 70 and 110 °C. These changes in properties are attributed to the formation of hydrogen bonds between the species. However, the degree of substitution and the viscosity of the CMC affects the physical, chemical, and biological properties of the polymer obtained. The supramolecular polymers are biodegradable regardless of the type of blends made and are easily obtainable. Notably, the CMC with m-nitrophenylmaleimide yields the polymer with the best properties.

Int J Mol Sci 2022; 23:ijms23147943. [PMID: 35887292 PMCID: PMC9319702 DOI: 10.3390/ijms23147943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 07/12/2022] [Accepted: 07/14/2022] [Indexed: 12/04/2022] Open
Abstract
Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease characterized by parenchymal scarring, leading progressively to alveolar architecture distortion, respiratory failure, and eventually death. Currently, there is no effective treatment for IPF. Previously, 3′5-dimaleamylbenzoic acid (3′5-DMBA), a maleimide, demonstrated pro-apoptotic, anti-inflammatory, and anti-cancer properties; however, its potential therapeutic effects on IPF have not been addressed. Bleomycin (BLM) 100 U/kg was administered to CD1 mice through an osmotic minipump. After fourteen days of BLM administration, 3′5-DMBA (6 mg/kg or 10 mg/kg) and its vehicle carboxymethylcellulose (CMC) were administered intragastrically every two days until day 26. On day 28, all mice were euthanized. The 3′5-DMBA effect was assessed by histological and immunohistochemical staining, as well as by RT-qPCR. The redox status on lung tissue was evaluated by determining the glutathione content and the GSH/GSSG ratio. 3′5-DMBA treatment re-established typical lung histological features and decreased the expression of BLM-induced fibrotic markers: collagen, α-SMA, and TGF-β1. Furthermore, 3′5-DMBA significantly reduced the expression of genes involved in fibrogenesis. In addition, it decreased reduced glutathione and increased oxidized glutathione content without promoting oxidative damage to lipids, as evidenced by the decrease in the lipid peroxidation marker 4-HNE. Therefore, 3′5-DMBA may be a promising candidate for IPF treatment.

Abstract
A simple and efficient BF3-OEt2 promoted C3-alkylation of indole has been developed to obtain3-indolylsuccinimidesfrom commercially available indoles and maleimides, with excellent yields under mild reaction conditions. Furthermore, anti-proliferative activity of these conjugates was evaluated against HT-29 (Colorectal), Hepg2 (Liver) and A549 (Lung) human cancer cell lines. One of the compounds, 3w, having N,N-Dimethylatedindolylsuccinimide is a potent congener amongst the series with IC50 value 0.02 µM and 0.8 µM against HT-29 and Hepg2 cell lines, respectively, and compound 3i was most active amongst the series with IC50 value 1.5 µM against A549 cells. Molecular docking study and mechanism of reaction have briefly beendiscussed. This method is better than previous reports in view of yield and substrate scope including electron deficient indoles.

Oxoglutarate Carrier Inhibition Reduced Melanoma Growth and Invasion by Reducing ATP Production. Pharmaceutics 2020; 12:pharmaceutics12111128.

Abstract
Recent findings indicate that (a) mitochondria in proliferating cancer cells are functional, (b) cancer cells use more oxygen than normal cells for oxidative phosphorylation, and (c) cancer cells critically rely on cytosolic NADH transported into mitochondria via the malate-aspartate shuttle (MAS) for ATP production. In a spontaneous lung cancer model, tumor growth was reduced by 50% in heterozygous oxoglutarate carrier (OGC) knock-out mice compared with wild-type counterparts. To determine the mechanism through which OGC promotes tumor growth, the effects of the OGC inhibitor N-phenylmaleimide (NPM) on mitochondrial activity, oxygen consumption, and ATP production were evaluated in melanoma cell lines. NPM suppressed oxygen consumption and decreased ATP production in melanoma cells in a dose-dependent manner. NPM also reduced the proliferation of melanoma cells. To test the effects of NPM on tumor growth and metastasis in vivo, NPM was administered in a human melanoma xenograft model. NPM reduced tumor growth by approximately 50% and reduced melanoma invasion by 70% at a dose of 20 mg/kg. Therefore, blocking OGC activity may be a useful approach for cancer therapy.

Abstract
In a search for anticancer drugs by screening for inhibitors of telomerase, we have identified several small-molecule inhibitors that selectively inhibit telomerase in a cell-free system. Among these inhibitors, N-(1-pyrenyl) maleimide (NPM) induced apoptosis and displayed the greatest differential cytotoxicity against acute T cell leukemia-derived Jurkat cells cultured in vitro. In this work, the in vivo anti-leukemia activity of NPM was investigated using a bioluminescent mouse model. The luciferase-expressing Jurkat cells (Jurkat-Luc) were mixed with matrigel and injected subcutaneously into the nude mice. Drug treatment was commenced on day 7 after tumor implantation. The growth of xenografted tumors was significantly inhibited in the mice treated with NPM, which is comparable to the inhibitory effect of a classical anti-leukemia drug, cyclophosphamide. Combined treatment with NPM and cyclophosphamide further enhanced the growth inhibition of xenografted Jurkat-Luc cells. Immunohistochemistry staining with cleaved caspase 3 (cl-caspase 3) indicated a very heavy staining of cl-caspase 3 only in the tumor implants excised from the NPM-treated mice. We conclude that NPM induced apoptosis and inhibited the growth of xenografted Jurkat-Luc cells in nude mice, demonstrating that NPM displays anti-leukemia activity in vivo.

Abstract
N-(1-pyrenyl) maleimide (NPM) is a fluorescent reagent that is frequently used as a derivatization agent for the detection of thio-containing compounds. NPM has been shown to display a great differential cytotoxicity against hematopoietic cancer cells. In this study, the molecular mechanism by which NPM induces apoptosis was examined. Here, we show that treatment of Jurkat cells with NPM leads to Bak oligomerization, loss of mitochondrial membrane potential (Δψm), and release of cytochrome C from mitochondria to cytosol. Induction of Bak oligomerization appears to play a critical role in NPM-induced apoptosis, as downregulation of Bak by shRNA significantly prevented NPM-induced apoptosis. Inhibition of caspase 8 by Z-IETD-FMK and/or depletion of Bid did not affect NPM-induced oligomerization of Bak. Taken together, these results suggest that NPM-induced apoptosis is mediated through a pathway that is independent of caspase-8 activation.

Abstract
Several lines of evidence suggest that hnRNPs A/B (hnRNPs A1, A2/B1, and A3) play an important role in proliferation, although the functional overlap among members of hnRNPs A/B remains largely unknown. In this study, we have employed RNAi knockdown and proteomic approaches to investigate the biological functions of hnRNPs A/B. Depletion of hnRNP A2, but not A1 or A3, produced a significant inhibition of cellular proliferation in Jurkat cells. Analysis of the proteomes in the cells depleted for hnRNP A1, A2, or A3 has identified a total of 167 differentially expressed proteins in the depleted cells. Network analysis of the proteins altered in the cells depleted for hnRNP A2 revealed that the biological processes likely affected by these proteins are related to cell cycle, cytoskeleton rearrangement, and transcription regulation. Indeed, we have confirmed that the level of RhoA and CrkL was selectively reduced in the cells depleted of hnRNP A2, but not in the cells depleted for hnRNP A1 or A3. Therefore, we suggest that the reduced proliferation observed in the cells depleted of hnRNP A2 may result from its effects on cell adhesion processes in the Jurkat cells.
