Silver(I)-N-heterocyclic carbene complexes challenge cancer; evaluation of their anticancer properties and in silico studies.

Drug Dev Res 2021 May 12. Epub 2021 May 12.

Department of Pharmaceutical Biotechnology, Faculty of Pharmacy, Sivas Cumhuriyet University, Sivas, Turkey.

Because of the continuous need for efficient therapeutic agents against various kinds of cancers and infectious diseases, the pharmaceutical industry has to find new candidates and strategies to develop novel and efficient drugs. They increasingly use computational tools in R&D stages for screening extensive sets of drug candidates before starting pre-clinical and clinical trials. N-Heterocyclic carbenes (NHCs) can be evaluated as good drug candidates because they offer both anti-cancer and anti-inflammatory features with their general low-toxicity profiles. Read More

Near-infrared absorbing Ru(ii) complexes act as immunoprotective photodynamic therapy (PDT) agents against aggressive melanoma.

Chem Sci 2020 Nov 9;11(43):11740-11762. Epub 2020 Sep 9.

Department of Chemistry and Biochemistry, The University of Texas at Arlington Arlington Texas 76019-0065 USA

Mounting evidence over the past 20 years suggests that photodynamic therapy (PDT), an anticancer modality known mostly as a local treatment, has the capacity to invoke a systemic antitumor immune response, leading to protection against tumor recurrence. For aggressive cancers such as melanoma, where chemotherapy and radiotherapy are ineffective, immunomodulating PDT as an adjuvant to surgery is of interest. Towards the development of specialized photosensitizers (PSs) for treating pigmented melanomas, nine new near-infrared (NIR) absorbing PSs based on a Ru(ii) tris-heteroleptic scaffold [Ru(NNN)(NN)(L)]Cl , were explored.

Synergistic effect of the anti-PD-1 antibody with blood stable and reduction sensitive curcumin micelles on colon cancer.

Drug Deliv 2021 Dec;28(1):930-942

Department of Cell Biology, School of Basic Medical Sciences, Southern Medical University, Guangzhou, China.

Curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione) is a potent anticancer drug with versatile biological activities, while the clinical translation of curcumin is severely limited due to its hydrophobicity, rapid elimination, and metabolism in the blood circulation. Herein, we aim to unravel the potential of curcumin as a synergistic agent with immunotherapy in the treatment of cancers. In an effort to minimize premature release and improve the systemic bioavailability, a superior blood stable and reduction sensitive curcumin micellar formulation, of which the release can be triggered by cancer cells, is rationally designed.

Glutathione-Depleting Nanomedicines for Synergistic Cancer Therapy.

ACS Nano 2021 May 11. Epub 2021 May 11.

State Key Laboratory of Bioelectronics, School of Biological Science and Medical Engineering, Southeast University, 2 Sipailou Road, Nanjing 210096, P.R. China.

Cancer cells frequently exhibit resistance to various molecular and nanoscale drugs, which inevitably affects the drugs' therapeutic outcomes. Overexpression of glutathione (GSH) has been observed in many cancer cells, and solid evidence has corroborated the resulting tumor resistance to a variety of anticancer therapies, suggesting that this biochemical characteristic of cancer cells can be developed as a potential target for cancer treatments. The single treatment of GSH-depleting agents can potentiate the responses of the cancer cells to different cell death stimuli; therefore, as an adjunctive strategy, GSH depletion is usually combined with mainstream cancer therapies for enhancing the therapeutic outcomes.

J Gastrointest Cancer 2021 May 11. Epub 2021 May 11.

Department of Botany and Microbiology, Faculty of Science, Al-Azhar Uniersity, 11847, Nasr City, Cairo, Egypt.

The present work aimed to study the activity of naturally derived fungal secondary metabolites as anticancer agents concerning their cytotoxicity, apoptotic, genetic, and histopathological profile. It was noticed that Aspergillus terreus, Aspergillus flavus, and Aspergillus fumigatus induced variable toxic potential that was cell type, secondary metabolite type, and concentration dependent. Human colonic adenocarcinoma cells (Caco-2) showed less sensitivity than hepatocyte-derived cellular carcinoma cells (HuH-7), and in turn, the half-maximal inhibitory concentration (IC) was variable.

Novel antimicrobial anionic cecropins from the spruce budworm feature a poly-L-aspartic acid C-terminus.

Proteins 2021 May 11. Epub 2021 May 11.

Institut de biologie intégrative et des systèmes (IBIS) and Faculté de médecine, Université Laval, Quebec City, Canada.

Cecropins form a family of amphipathic α-helical cationic peptides with broad-spectrum antibacterial properties and potent anticancer activity. The emergence of bacteria and cancer cells showing resistance to cationic antimicrobial peptides (CAMPs) has fostered a search for new, more selective and more effective alternatives to CAMPs. With this goal in mind, we looked for cecropin homologs in the genome and transcriptome of the spruce budworm, Choristoneura fumiferana. Read More

RRx-001 ameliorates inflammatory diseases by acting as a potent covalent NLRP3 inhibitor.

Cell Mol Immunol 2021 May 10. Epub 2021 May 10.

Hefei National Laboratory for Physical Sciences at Microscale, the CAS Key Laboratory of Innate Immunity and Chronic Disease, School of Basic Medical Sciences, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China.

The NLRP3 inflammasome plays a crucial role in innate immune-mediated inflammation and contributes to the pathogenesis of multiple autoinflammatory, metabolic and neurodegenerative diseases, but medications targeting the NLRP3 inflammasome are not available for clinical use. RRx-001 is a well-tolerated anticancer agent currently being investigated in phase III clinical trials, but its effects on inflammatory diseases are not known. Here, we show that RRx-001 is a highly selective and potent NLRP3 inhibitor that has strong beneficial effects on NLRP3-driven inflammatory diseases. Read More

Bortezomib induces methylation changes in neuroblastoma cells that appear to play a significant role in resistance development to this compound.

Sci Rep 2021 May 10;11(1):9846. Epub 2021 May 10.

Department of General Pathology, Pomeranian Medical University, Powstańców Wlkp. 72, 70-111, Szczecin, Poland.

The anticancer activity of bortezomib (BTZ) has been increasingly studied in a number of indications and promising results for the use of this treatment have been shown in neuroblastoma. As BTZ treatment is usually administered in cycles, the development of resistance and side effects in patients undergoing therapy with BTZ remains a major challenge for the clinical usage of this compound. Common resistance development also means that certain cells are able to survive BTZ treatment and bypass molecular mechanisms that render BTZ anticancer activity. Read More
