Special Issue Information

Dear Colleagues,

Regulated cell death (RCD) plays a significant role in the homeostasis of the body, both in physiological and pathological conditions. Excessive or insufficient RCD can cause diseases. RCD can take many forms, including apoptosis, necroptosis, or ferroptosis. Cells may be sensitive or resistant to different death types, which depends on the cell’s origin and treatment. For a long time, a considerable amount of interest has been paid towards searching for less well-known anticancer agents, especially with proapoptotic activities. They were found to be good targets for drug repurposing because of their proven safety, inexpensiveness, quality, and well-known ways of synthesis. Some of them exhibit a wide range of biological activities, such as anticancer, antiviral, anti-inflammatory, immunosupressive, antibacterial, and reversal of multidrug resistance. A variable type of biologically active molecules, natural or artificially synthesized, were used during the 19th–20th centuries due to their health benefits. However, validated studies of their derivatives, based on different nanoparticles, composed drug delivery systems, encapsulates, etc., with an effect on malignant tumor cells, have only begun within the last few decades. Proapoptotic agents and inducers of cellular death pathways are still the best players in anticancer strategies.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceuticals is an international peer-reviewed open access monthly journal published by MDPI.

Therapeutically targeting senescent cells seems to be an interesting perspective in treating chronic lung diseases, which are often associated with human aging. The combination of the drug dasatinib and the polyphenol quercetin is used in clinical trials as a senolytic, and the first results point to the relief of physical dysfunction in patients with idiopathic pulmonary fibrosis. In this work, we tested new combinations of drugs and polyphenols, looking for senolytic activity using human lung fibroblasts (MRC-5 cell line) with induced senescence. We researched drugs, such as azithromycin, rapamycin, metformin, FK-506, aspirin, and dasatinib combined with nine natural polyphenols, namely caffeic acid, chlorogenic acid, ellagic acid, ferulic acid, gallic acid, epicatechin, hesperidin, quercetin, and resveratrol. We found new effective senolytic combinations with dasatinib and ellagic acid and dasatinib and resveratrol. Both drug combinations increased apoptosis, reduced BCL-2 expression, and increased caspase activity in senescent MRC-5 cells. Ellagic acid senolytic activity was more potent than quercetin, and resveratrol counteracted inflammatory cytokine release during senolysis in vitro. In conclusion, dasatinib and ellagic acid and dasatinib and resveratrol present in vitro senolytic potential like that observed for the combination in clinical trials of dasatinib and quercetin, and maybe they could be future alternatives in the senotherapeutic field.
