Angewandte Chemie, Volume 133, Issue 31, Page 17011-17016, July 26, 2021., 2021 Neue bakterielle Chalconisomerasen und deren Varianten wurden durch eine Sequenz‐Struktur‐Funktions‐Evolutions (SSFE)‐Strategie identifiziert. Diese sind in der Lage, Chalcone in Flavanone mit breitem Substratspektrum und strikter (S)‐Stereopräferenz zu überführen, was eine biokatalytische Route zu (S)‐Flavanonen eröffnet. Abstract Die Chalconisomerase

Nutrients, 2013 Asthma is a chronic disease, characterized by airway inflammation, airflow limitation, hyper-reactivity and airway remodeling. It is believed that asthma is caused by the interaction between genetic and environmental factors. The prevalence of allergic diseases, including asthma, has increased worldwide during the past two decades. Although the precise

Photoangeregte Anionen in organischen Reaktionen
Angewandte Chemie, Volume 133, Issue 12, Page 6338-6363, March 15, 2021., 2021 Photoangeregte Anionen wirken stark reduzierend und können als Katalysatoren oder als Reaktanten eingesetzt werden. In Gegenwart von Basen verschiebt sich die Absorption durch Deprotonierung im Vergleich zur neutralen Spezies bathochrom. Daher ist häufig eine Anregung mit sichtbarem Licht möglich.

Neuroprotection by flavonoids [PDF]
Brazilian Journal of Medical and Biological Research, 2003 The high morbidity, high socioeconomic costs and lack of specific treatments are key factors that define the relevance of brain pathology for human health and the importance of research on neuronal protective agents. Epidemiological studies have shown beneficial effects of flavonoids on arteriosclerosis-related pathology in general and ...

Molecules, 2011 Flavonoids are present in almost all terrestrial plants, where they provide UV-protection and colour. Flavonoids have a fused ring system consisting of an aromatic ring and a benzopyran ring with a phenyl substituent. The flavonoids can be divided into several classes depending on their structure. Flavonoids are present in food and medicinal plants and

Biosynthesis of Flavonoids [PDF]
Nature, 1960 SEVERAL workers have shown that lignin and the ‘B ring’ of flavonoids are formed in vivo from shikimic acid and certain C6C3 compounds. The latter compounds are frequently encountered in plant tissues1. The ‘A ring’ of flavonoids appears to arise from acetate units2.
