Safety and Effectivness of Quercetin & Dasatinib on Epigenetic Aging, Long-term treatment with senolytic drugs Dasatinib and Quercetin ameliorates age-dependent intervertebral disc degeneration in mice, Senolytic Combination of Dasatinib and Quercetin Alleviates Intestinal Senescence and Inflammation and Modulates the Gut Microbiome in Aged Mice. These improvements were consistent with preclinical findings of improvements in treadmill endurance and frailty following senescent cell removal in various murine models. These conditions include frailty, cataracts, age-related osteoporosis, age-related muscle loss, radiation-induced damage, cardiac dysfunction, vascular dysfunction and calcification, pulmonary fibrosis, hepatic steatosis, metabolic syndrome, diabetes, and dementia. Its absorption is affected by differences in its glycosylation, the food matrix from which it is consumed, and the co-administration of dietary components such as fiber and fat (, After absorption, quercetin is metabolized in various organs including the small intestine, colon, liver, and kidney. More clinical research is required to get population-specific doses of senolytics to improve anti-aging features with reduced side effects. Current therapeutic interventions for aging are targeted at cellular senescence. To determine whether reducing senescent cells protects against hyperoxia-induced lung injury, we administered the senolytic cocktail quercetin/dasatinib (2.5 and 5 mg/kg, i.p.) These findings indicate a potential therapeutic promise for use in humans to address aging. Insomnia that resulted in only 2-3 hours of sleep was also described in a case report in which thepatient was taking a lower dose of dasatinib, 25 mg/day on alternate weeks, although he had taken higher doses in the past (Sami et al., 2014). PE developed at a rate of 8% per year but the earliest time of onset was not reported (Cortes et al., 2016). A trial that used intermittent treatment with D+Q (5 mg/kg + 50 mg/kg) weekly in an accelerated aging mouse model found that healthspan was significantly extended (Zhu et al., 2015). The median duration of first-time cases of PE was 4 weeks. Quercetin, like dopamine, is a substrate for catechol-O-methyl transferase (COMT) and reportedly can be metabolized by intestinal flora to yield homovanillic acid and other metabolites that are absorbed and excreted. Published results exist from 3 human trials, two in diseased populations and one in healthy subjects. Three preclinical trials in mice reported beneficial effects in the CNS due to the elimination of senescent cells (Ogrodnik et al., 2019; Zhang et al., 2019; Musi et al., 2018). Severe cases occurred in only 1-4% of subjects within the trials. Begin yesterday morning, at 9:30am I calculated the dosage at 200mg Dasatinib and 2000mg Quercertin. Fisetin treated male mice had . Most excretion is by way of feces. Like other types of effusions, these are likely due to effects on the endothelium. Studies have shown that increased blood pressure, previous cardiac disease, and administering D twice daily, are all associated with a higher risk of PE. Senescent cells often express p16INK4a, a cyclin-dependent kinase inhibitor, tumor suppressor, and biomarker of aging, which renders the senescence growth arrest irreversible (, study reported a decrease of approximately 9.5% in human explanted adipose tissue (, ). The .gov means its official. The Forever Healthy Foundation announces the public launch of the Risk-Benefit Analysis of Dasatinib + Quercetin as a Senolytic Therapy, a structured review of the published evidence. Senescent cells accumulate after radiation exposure, which can induce cell and tissue dysfunction and skin or mucous membrane ulcers (Wang et al., 2020). Cell Signal. In some trials, there was a single cycle only while others repeated treatment weekly for 3 weeks or every 16 days for 6 cycles. Anorexia was reported by many studies at frequencies between 17-69%. In D+Q treated aged female mice, p53 was upregulated in uterine tissue and profibrotic factor miR34c was significantly reduced suggesting a possible anti-fibrotic effect (Cavalcante et al., 2019). Other case reports describe acute renal failure occurring after one month (Ozkurt et al., 2010) or more than a year of treatment with D (Kaiafa et al., 2014). An in vitro study found that dasatinib dramatically inhibits endothelial cell tube formation which is essential for proper function and angiogenesis (Gover-Proaktor et al., 2018) providing a possible mechanistic explanation for its effects on the vascular system. Due to the role of senescent cells in causing age-related degeneration, these widely known senolytics show a possibility of reducing this biological process. How likely adverse effects are to occur with intermittent combined D+Q treatment is largely unknown. 2022 Jun 21;11(13):1992. doi: 10.3390/cells11131992. The dose required to produce this effect in the mouse was 20mg/kg which is higher than the currently used dose in humans. The most distinguishing event was myocardial infarction, where seven patients in the D group and one patient in the placebo arm experienced a heart attack. It works by blocking the action of a protein called tyrosine kinase. If this pharmaceutical combination works in humans as an anti-aging supplement, it can be afforded by a sizable portion of the worlds population if the prices do not increase. In mice, D+Q treatment has been shown to reduceyH2AX in liver biopsies 17% down to 11% (Ogrodnik et al., 2017). The first in vivo cell atlas of senescent tissue in skeletal muscle has identified the damaging properties of these cells and explained why they block muscle regeneration. Nephrotic-range proteinuria has also been reported (Wallace et al., 2013) with an onset approximately 3 months after D initiation. The following "tornado" diagram summarizes the results of the previous sections: To view the tornado diagram as a pdf please click on the thumbnail below: For those who would prefer to view thedocumentin excel, we have includedthe original .xls file. Another retrospective analysis (n=43) reported that 23.3% of patients developed hypertriglyceridemia by 6 months, with the earliest onset after one month of treatment (Lu Yu et al., 2019). All reported events were of mild-moderate severity. Analysis of quercetin metabolites in plasma and liver have shown that the concentrations of its derivatives in the liver were lower than those in plasma, and the hepatic metabolites were extensively methylated (90%95%) (, Research suggests that quercetin and its metabolites tend to accumulate in the organs involved in its metabolism and excretion and that perhaps mitochondria might be an area of quercetin concentration within cells (, Elimination is quite slow, with a reported half-life ranging from 11 to 28 h and an average terminal half-life of 3.5 h (, Q is an antioxidant and specific quinone reductase 2 (QR2) inhibitor, an enzyme (along with the human QR1 homolog) that catalyzes the metabolism of toxic quinolines (, Estimated daily intake in Western diets ranges from 3-40 mg. With a high intake of fruit and vegetables, this can rise to 250 mg/day (, D+Q were identified as being potentially senolytic using apriori knowledge about their targets in relation to their ability to disable the SCAP networks (. An analysis of SASP gene signatures in skin biopsies from a trial (n=12) that used D (100 mg) for 169 days to treat systemic sclerosis-associated interstitial lung disease (Martyanov et al., 2019) found that in the subset of patients that responded to D treatment (n=3) SASP levels were both higher at baseline and, significantly lower post-treatment compared with non-improvers. These drugs have a wide array of therapeutic uses in aging, and a combination of both is not uncommon in anti-aging studies. Here, we demonstrate that dasatinib and quercetin (D&Q) have senolytic effects, reducing age-related increase in senescence-associated -galactosidase, expression of p16 and p21 gene and P16 protein in perigonadal white adipose tissue (pgWAT; all p 0.04). More than 15 million adults in the United States suffer from chronic back pain. Syncope was reported as an adverse event in a trial that used D to treat sarcoma. The human body harbors an estimated 38 trillion bacteria, which outnumber human cells. Senolytics are a new class of drugs that clear out old, damaged cells in the body, and they show promise in combating age-related diseases. Anyone considering taking quercetin should speak to a healthcare professional first to discuss the potential risks and benefits. The combination of Dasatibin and Quercetin has only been applied in controlled clinical trials. Copyright 2023, EASYCOCKTAILIDEAS - All Rights Reserved. Our analysis identified a total of only 8 benefits that have been documented in human studiesand another 46 benefits from preclinical trials (Table 4). 2019 Mar 15;20(6):1323. doi: 10.3390/ijms20061323. Histological examination showed fewer osteoclasts and femur cortical thickness and bone strength were higher in the D+Q group. Dasatinib dissolves better in low pH values, leading to more of the drug being absorbed into the blood. sharing sensitive information, make sure youre on a federal The drug combination is administered intermittently and continuously because of their short half-lives. A second trial (n=174) reported that dizziness occurred in 10% of subjects (Apperley et al., 2009) and a third trial (n=54) reported dizziness in 5.4% of patients (Wong et al., 2018). The desire to live longer may be a possibility in the future if the pharmaceutical combination of anti-aging drugs is proven for wider population use. We identified 31 preclinical trials related to the use of D+Q as senolytics, alone or in combination. Muscle cramps were also reported as an adverse effect in 8.8% of patients (n=69)(Chen et al., 2018). D-induced heart failure has been correlated to the inhibition of non-receptor type protein kinase ABL1 and ABL2 based on pharmacovigilance data (Izumi-Nakaseko et al., 2019). Dasatinib + Quercetin (D + Q) worsens liver disease progression in the diethylnitrosamine (DEN) / high fat diet (HFD) mouse model. Which benefits result from D+Q senolytic therapy? A study of genetic clearance of senolytic cells has shown a delay in wound healing and increased fibrosis after the wound is healed (Demaria et al., 2014). When senescent cells were transplanted into young mice, D+Q prevented the decreases in hanging endurance, grip strength, and speed that were seen in vehicle fed mice. There were 7 reports of abnormalities such as encephalocele, renal tract abnormalities, and hydrops fetalis. This site needs JavaScript to work properly. Src tyrosine kinase is expressed abundantly in vascular tissue, and activation of Src appears to play a crucial role in smooth muscle cell proliferation and vasoconstriction. Pericardial effusion (+/- cardiac tamponade) has been reported as an adverse effect in several clinical trials and case reports at varying frequencies that appear to be dose-dependent. It appears that senolytics work by facilitating apoptosis of senescent cells due to their SASP, not by targeting all cells expressing pINK4a (, The changes in multiple tissues (skin, adipose tissue, plasma) suggest that oral administration of D+Q decreases overall senescent cell burden rather than targeting cells within a single organ or structure (, Decreases in circulating SASP factors/gene expression, An open-label trial (n=9) found that there was a decrease in circulating SASP factors (plasma IL-1a, IL-2, IL- 6, IL-9 and MMP 2, MMP 9, and MMP 12) following 3 days of senolytic treatment (, A second open-label trial (n=14) in patients with idiopathic pulmonary fibrosis (IPF) found that select SASP proteins including IL-6, MMP-7 and TIMP2 showed a trend towards reduction (8 participants had reductions in circulating amounts) following treatment with D+Q 3 days per week for 3 weeks (, An analysis of SASP gene signatures in skin biopsies from a trial (n=12) that used D (100 mg) for 169 days to treat systemic sclerosis-associated interstitial lung disease (, One RCT (n=64) in healthy volunteers (over the age of 36 years) reported a significant reduction in post-exercise systolic blood pressure at 10 and 20 minutes in the group that received treatment with D+Q for 5 days (, An open-label trial reported improvements in physical function that included improved 6-min walk distance, 4-m gait speed, and 5-repeated chair-stand times (, One RCT (n=64) in healthy volunteers reported that nearly all participants in the D+Q group experienced a feeling of "lightness" in the joints the day after treatment (, A trial that used intermittent treatment with D+Q (5 mg/kg + 50 mg/kg) weekly in an accelerated aging mouse model found that healthspan was significantly extended (, A second study reported that bi-weekly administration of D+Q (5 mg/kg + 50 mg/kg)starting at 24-27 months of age (equivalent to age 75-90 years in humans) resulted in a 36% higher median post-treatment lifespan and lower mortality hazard (64.9% compared to the control group), Three preclinical trials in mice reported beneficial effects in the CNS due to the elimination of senescent cells (, of senescent glial cells in the region of the, (5 mg/kg+ 50 mg/kg) for 5 days every two weeks over 8 weeks restored neurogenesis and alleviated, Using AD transgenic mouse models, a third trial (, Four preclinical studies reported benefits to the cardiovascular system following treatment with D+Q (, The first trial, assessed the effect of D+Q ( 5 mg/kg + 10 mg/kg) once per month for 3 months in aged and atherosclerotic mice (, A single dose of D+Q (5 mg/kg + 50 mg/kg) has been shown to improve left ventricular ejection fraction in mice by approximately 10% (from 68% baseline up to 78% following treatment) due to improvements in end-systolic cardiac dimensions (, D+Q treatment also improved vasomotor function in two trials (, Elimination of senescent cardiac progenitor cells (CPCs) using D+Q has been shown, Improved cardiac diastolic function following D+Q treatment was reported by a study in obese mice (, Incubation with Q (3-12 M for 24 hours) has been shown to increase the expression of SIRT1 and thioredoxin in a dose-dependent manner in human kidney cells (, One trial reported a decrease in the inflammatory aspects of IPF in bronchoalveolar lavage (BAL) fluid following treatment with D+Q. 21 ; 11 ( 6 ):1037. doi: 10.3390/antiox11061037 treatment is largely unknown occurred in only 1-4 % patients!
