Creation of a new molecule through innovative combination of two reactions

Building up new macrocyclic molecules using both dynamic covalent and coordination reactions

Creation of a new molecule through innovative combination of two reactions
2023-06-13
(Press-News.org)

A research group led by Professor Hideki Fujiwara and Associate Professor Daisuke Sakamaki from the Graduate School of Science at Osaka Metropolitan University succeeded, for the first time, in synthesizing a new molecule using a novel combination of dynamic covalent chemistry, in which organic radicals couple and dissociate reversibly, and coordination chemistry, which binds radicals to metal ligands. The study shows that the two types of reactions work without inhibiting each other.

“This research was based on a very simple idea of combining two types of reactions,” stated Professor Sakamaki. “However, it was not clear if these reactions could coexist because they are so different in nature. Our results are expected to contribute to the development of new synthetic components for functional materials, such as sensing materials and porous materials.”

The study findings were published in Angewandte Chemie International Edition.

Elevated Lipoprotein(a) is the latest variant of ‘bad cholesterol’ found to increase the risk of recurrent coronary heart disease

2023-06-13
Increased levels of Lipoprotein(a), a variant of ‘bad cholesterol’, in the bloodstream are a risk factor for recurrent coronary heart disease (CHD) in people aged 60 or over, according to the results of a new study which tracked the issue over the course of 16 years. The results, published today in Current Medical Research & Opinion, suggest that current cholesterol-lowering medications may not be effective at reducing the risk of recurrent CHD – such as a heart attack – due to elevated Lp(a). “This finding adds to growing evidence of a relationship between increased Lp(a) and the risk of recurrent CHD,” says lead author Associate Professor ...

MOVA: new method for evaluating the pathogenicity of missense variants using AlphaFold2

MOVA: new method for evaluating the pathogenicity of missense variants using AlphaFold2
2023-06-13
Niigata, Japan - The Department of Neurology at Niigata University has developed a new in silico method for evaluating the pathogenicity of missense variants using AlphaFold2 (MOVA). Rare variants in the causative gene of ALS are present in 10-30% of sporadic ALS cases, which highlights the need for accurate and efficient pathogenicity prediction methods. To predict the pathogenicity of the variants, in silico analysis methods are commonly used. In some ALS causal genes, the mutations are concentrated in specific regions, and the accuracy of pathogenicity prediction can be improved by considering the positional information of the variants. ...

23Na MRI technique unleashes new approach for diagnosing diabetic kidney disease

23Na MRI technique unleashes new approach for diagnosing diabetic kidney disease
2023-06-13
Niigata, Japan - The gold standard test for predicting the onset of diabetic kidney disease is albuminuria. However, detecting albuminuria alone has limited sensitivity and specificity in end-stage renal failure with a decreased estimated glomerular filtration rate. This is supported by several reports, which state that about half of the type 2 diabetes patients who developed kidney dysfunction showed no preceding albuminuria. In this study, the authors propose the possibility of diagnosing tubular abnormalities in diabetic kidney disease at an early stage and connecting them to treatment by combining the evaluation of sodium concentration using 23Na MRI ...

Immune cell movement worse in older females, mice study finds

2023-06-13
Older female mice had more immune cells entering areas of the body where they shouldn’t according to a new study, demonstrating that sex differences contribute to age-related inflammation that needs to be considered in future research.   In a paper published in Journal of Leukocyte Biology today (Tuesday 13 June), at team of researchers led by Dr Myriam Chimen from the University of Birmingham have found that age significantly increases the number of immune cells entering the sack that holds major organs (peritoneal cavity) in female mice, when compared to young mice or older male mice.   The findings support previous studies that suggest ...

THE LANCET: First phase 3 trial of a chikungunya vaccine candidate finds it is generally safe and provokes an immune response

2023-06-13
Peer-reviewed / Randomised Controlled Trial / People Study of healthy US adults found that a single dose of the VLA1553 vaccine candidate was generally safe, well tolerated and provokes an immune response. After a single vaccination, the vaccine produced neutralizing antibody levels which are thought to protect against chikungunya disease in 99% (263/266) of participants. Antibody levels declined 28 days after vaccination, but seroprotection persisted in more than 96% (233/242) participants after six months. Most adverse events were moderate or mild and the authors say its safety profile is similar to other licensed vaccines The VLA1553 vaccine candidate ...

Glasgow, UK:  The informed consent process in biomedical research is biased towards people who can meet with clinical study staff during the working day. For those who have the availability to have a consent conversation, the time burden can be off-putting. Professor Eric Vilain, from the Department of Paediatrics, University of California, Irvine, USA, will tell the European Society of Human Genetics annual conference today (Tuesday 13 June) how results from his team’s study of the use of a chatbot (GIA – ‘Genetics Information Assistant’ ...
