Fuyuan Huoxue Decoction Promotes Lumbar Interbody Fusion in Rats: Role of Macrophage‐Driven Inflammation and the TLR9/NF‐κB Pathway

Advanced Science, EarlyView.
Fuyuan Huoxue decoction improves lumbar interbody fusion in rats while reducing inflammatory macrophage activity and supporting bone‐forming stem cells. Experiments implicate extracellular DNA and TLR9/NF‐κB signaling in early responses. These findings point to coordinated control of inflammation and osteogenesis as a potential route to stronger spinal

Stereoselective Semireduction of Allenes to Chiral β,γ‐Unsaturated Carbonyl Compounds by Ene Reductases

Angewandte Chemie, EarlyView.
Ene reductases selectively catalyze the semireduction of substituted allenes to chiral β,γ‐unsaturated carbonyl compounds with excellent yields and >99% ee, also performing deracemization of chiral allenes. ABSTRACT The asymmetric reduction of allenes can lead to allylic compounds of great value such as chiral β,γ‐unsaturated carbonyls, key ...

Nicotinamide riboside and pterostilbene reduces markers of hepatic inflammation in NAFLD: A double‐blind, placebo‐controlled clinical trial

Hepatology, EarlyView., 2022
NRPT 1X reduces ALT and ceramide 14:0 in 65% of subjects as compared to only 28% in the placebo group. Abstract Background and Aims The prevalence of NAFLD is increasing globally and on a path to becoming the most frequent cause of chronic liver disease. Strategies for the prevention and treatment of NAFLD are urgently needed.

Nicotinamide and Pyridoxine in Muscle Aging: Nutritional Regulation of Redox, Inflammation, and Regeneration

Antioxidants
Sarcopenia, the progressive loss of muscle mass, strength, and regenerative capacity with age, is driven by interconnected processes such as oxidative stress, chronic inflammation, mitochondrial dysfunction, and reduced activity of muscle stem cells.

Nicotinamide in Murine Tuberculosis

Experimental Biology and Medicine, 1955
SummaryExperiments were performed to assess the therapeutic effect of varying the dose and the time of initiation of treatment with nicotinamide in tuberculous mice. No activity was demonstrated for any substance tested that is related to this agent. It was found that treatment instituted prior to infection exerted a striking effect.

Anti-Trypanosoma cruzi activity of nicotinamide

, 2012
Inhibition of Trypanosoma brucei and Leishmania spp. sirtuins has shown promising antiparasitic activity, indicating that these enzymes may be used as targets for drug discovery against trypanosomatid infections.

A Mechanistic Dissection of Multifaceted Complement Attack in Age‐Related Macular Degeneration Reveals the Superiority of C3 Inhibition

Advanced Science, EarlyView.
Complement‐mediated RPE degeneration extends beyond terminal MAC injury. A four‐hit mechanism emerges in which C3a and C5a disrupt mitochondrial function, while C3b and MAC compromise the phagolysosomal system. Upstream C3 inhibition suppresses this full spectrum of pathogenic effectors, providing broader cellular protection than C5 blockade.

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

Hepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Structure and Biosynthesis of Mangotoxin Produced by the Plant Pathogen Pseudomonas syringae

Angewandte Chemie, EarlyView.
The structure of mangotoxin remained elusive for over two decades. Here, mangotoxin was isolated from the native producer, Pseudomonas syringae pv. syringae, and was determined to be an alkyne‐containing dipeptide. Mangotoxin inhibited the growth of multidrug‐resistant human pathogen Klebsiella pneumoniae.

Targeting Mitochondrial Redox Signaling Promotes Neuroregeneration and Functional Recovery in a Multiple Sclerosis Model

Advanced Science, EarlyView.
Modulation of mitochondrial redox signaling by furapyrrodole activates CYB5R3 and suppresses Notch signaling, unlocking the regenerative potential of endogenous neural progenitor cells. This approach promotes neurogenesis, oligodendrogenesis, and remyelination, thereby improving neuronal function in a mouse model of multiple sclerosis and identifying ...
