Unlocking the Drug Potential of the Bryostatin Family: Recent Advances in Product Synthesis and Biomedical Applications.

Unlocking the Drug Potential of the Bryostatin Family: Recent Advances in Product Synthesis and Biomedical Applications. Chemistry. 2019 Sep 03;: Authors: Wu R, Chen H, Chang N, Xu Y, Jiao J, Zhang H Abstract Bryostatins are a class of naturally occurring macrocyclic lactones with a unique fast developing portfolio of clinical applications, including treatment of AIDS, Alzheimer's disease and cancer. This comprehensive account summarizes the recent progress (2014-present) in the development of bryostatins, including their total synthesis and biomedical applications. An emphasis is placed on the discussion of bryostatin 1, the most-studied analog to date. This review highlights the synthetic and biological challenges of bryostatins and provides an outlook on their future development. PMID: 31479550 [PubMed - as supplied by publisher]

In conclusion, a polypharmacology approach of combining established, prolongevity drug inhibitors of specific nodes may be the most effective way to target the nutrient-sensing network to improve late-life health. Deletion of p38α in Neurons Slows Neural Stem Cell Decline and Loss of Cognitive Function in Mice https://www.fightaging.org/archives/2019/10/deletion-of-p38%ce%b1-in-neurons-slows-neural-stem-cell-decline-and-loss-of-cognitive-function-in-mice/ Researchers here provide evidence for p38α to be involved in the regulation of diminished neural stem cell activity with age. It is thought...

Abstract Detection of glutathione in human serum is of great importance for clinical diagnosis of various diseases, such as AIDS, diabetes mellitus, Alzheimer disease and cancer. In this work, a new water-soluble bismacrocyclic polyamine-derived compound, namely L, which contains two molecules of 4-nitro-1,2,3-benzoxa-diazole as the fluorophores, was designed and prepared. The experiments of selectivity of L toward metal ions showed it could rapidly and sensitively detect Hg2+ with a detection limit of 27 nM. Furthermore, the cell imaging and co-staining experiments in HeLa cells demonstrated that the L-Hg2+ pro...

In this study, β2∗ nAChR-containing receptors and lynx1 were identified using pull down studies from the mouse brain (Nissen et al., 2018), while ws-lynx1, SLURP-1 and SLURP-2 has been successfully mixed with human brain tissue to pull down multiple nAChR subtypes (Lyukmanova et al., 2016a,b; Thomsen et al., 2016). To support the in vivo interaction studies, a lynx1KO phenotype was ameliorated by crossing these mice into mutant mice null for α7 and β2 nAChR genes (Miwa et al., 2006). These in vivo studies provide an important biological context for the interactions observed within in vitro systems. ...

ConclusionThe most advanced phase III clinical applications led to the development of two vaccines containing QS-21 as part of AS, the Herpes Zoster vaccine (HZ/su) (ShingrixTM) which received a license in 2017 from the FDA and a marketing authorization in EU in 2018 and the RTS,S/AS01 vaccine (MosquirixTM) against malaria which was approved by the EMA in 2015 for further implementation in Sub Saharan countries for routine use.Graphical abstract

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...

In this study, we examined the benefits of early-onset, lifelong AET on predictors of health, inflammation, and cancer incidence in a naturally aging mouse model. Lifelong, voluntary wheel-running (O-AET; 26-month-old) prevented age-related declines in aerobic fitness and motor coordination vs. age-matched, sedentary controls (O-SED). AET also provided partial protection against sarcopenia, dynapenia, testicular atrophy, and overall organ pathology, hence augmenting the 'physiologic reserve' of lifelong runners. Systemic inflammation, as evidenced by a chronic elevation in 17 of 18 pro- and anti-inflammatory cytokin...

DiscussionWe hypothesize that caregivers who receive the decision aid will have lower levels of decisional conflict and higher levels of decision-making self-efficacy compared to the control group. We also hypothesize that the DECAD decision aid will reduce mammography use among older women with ADRD.Trial registrationClinical Trials Register,NCT03282097. Registered on 13 September 2017.

This study is the culmination of a decade of research that has repeatedly demonstrated that this vaccine can effectively and safely target in animal models what we think may cause Alzheimer's disease. I believe we're getting close to testing this therapy in people." Although earlier research established that antibodies significantly reduce amyloid buildup in the brain, researchers needed to find a safe way to introduce them into the body. A vaccine developed elsewhere showed promise in the early 2000s, but when tested in humans, it caused brain swelling in some patients. The new idea was to start with DNA codin...

Today's open access paper is, I think, chiefly interesting for the later section in which the authors ponder future directions for the treatment of aging via means of destroying or manipulating the activity of senescent cells. The accumulation of senescent cells is one of the root causes of aging. The creation of senescent cells happens constantly in the undamaged and fully functional tissues of young people, a tiny fraction of these senescent cells manage to evade destruction and linger to cause issues, and given enough time that fraction will grow large enough to kill you. Cellular senescence isn't the only harmful cause...
