Drug-induced senescence program may be activated both in normal and cancer cells as a consequence of chemotherapeutic treatment, leading to some adverse side effects such senescence-associated secretory phenotype (SASP), secondary senescence, promotion. Targeted elimination senescent can achieved by drugs with senolytic activity (senolytics), for example, the plant-derived natural compound quercetin, especially when co-treated kinase inhibitor dasatinib. In present study, three quercetin derivatives were synthesized tested improved action against etoposide-induced human mammary epithelial triple-negative breast vitro. Transformation catechol moiety into diphenylmethylene ketal addition acetyl groups molecule (QD3 derivative) promoted clearance judged increased apoptosis compared etoposide-treated cells. A QD3-mediated effect was accompanied decreased SA-beta galactosidase levels p27, IL-1β, IL-8, HSP70 Similar not observed conclusion, novel agent QD3 described acting Thus, new one-two punch anti-cancer strategy based on combined pro-senescence drug is proposed.

Cellular senescence is a hallmark of aging defined by stable exit from the cell cycle in response to cellular damage and stress. Senescent cells (SnCs) can develop characteristic pathogenic senescence-associated secretory phenotype (SASP) that drives secondary disrupts tissue homeostasis, resulting loss repair regeneration. The use transgenic mouse models which SnCs be genetically ablated has established key role for driving age-related disease. Importantly, senotherapeutics have been developed pharmacologically eliminate SnCs, termed senolytics, or suppress SASP other markers senescence, senomorphics. Based on extensive preclinical studies as well small clinical trials demonstrating benefits senotherapeutics, multiple are under way. This Review discusses diseases, strategies target approaches discover advances senolytics.

Abstract Ageing-associated functional decline of organs and increased risk for age-related chronic pathologies is driven in part by the accumulation senescent cells, which develop senescence-associated secretory phenotype (SASP). Here we show that procyanidin C1 (PCC1), a polyphenolic component grape seed extract (GSE), increases healthspan lifespan mice through its action on cells. By screening library natural products, find GSE, PCC1 as one active components, have specific effects At low concentrations, appears to inhibit SASP formation, whereas it selectively kills cells at higher possibly promoting production reactive oxygen species mitochondrial dysfunction. In rodent models, depletes treatment-damaged tumour microenvironment enhances therapeutic efficacy when co-administered with chemotherapy. Intermittent administration either irradiated, cell-implanted or naturally aged old alleviates physical dysfunction prolongs survival. We identify senotherapeutic agent vivo activity high potential further development clinical intervention delay, alleviate prevent pathologies.

Lung cancer stands as the primary contributor to cancer-related fatalities worldwide, affecting both genders. Two types exist where non-small cell lung (NSCLC), accounts for 80–85% and SCLC 10-15% of cases. NSCLC subtypes include adenocarcinoma, squamous carcinoma, large carcinoma. Smoking, second-hand smoke, radon gas, asbestos, other pollutants, genetic predisposition, COPD are risk factors. On hand, stresses such DNA damage, telomere shortening, oncogene activation cause a prolonged cycle halt, known senescence.

Skin aging is associated with the accumulation of senescent cells and related to many pathological changes, including decreased protection against pathogens, increased susceptibility irritation, delayed wound healing, cancer susceptibility. Senescent secrete a specific set pro-inflammatory mediators, referred as senescence-associated secretory phenotype (SASP), which can cause profound changes in tissue structure function. Thus, drugs that selectively eliminate (senolytics) or neutralize SASP (senostatics) represent an attractive therapeutic strategy for age-associated skin deterioration. There growing evidence plant-derived compounds (flavonoids) slow down even prevent aging-associated deterioration appearance function by targeting cellular pathways crucial regulating senescence SASP.
