Determination of individual coumarin in a dry extract of Melilotus officinalis L.
Разработка и регистрация лекарственных средств, 2021 Introduction. Substances of plant origin exhibit a variety of pharmacological activity in combination with a relatively low toxicity and frequency of side effects. In this regard, a promising direction is the standardization of substances of plant origin

Sequence‐Modulated Active Tripeptide Condensates for Tandem Catalysis
Angewandte Chemie, EarlyView.Sequence‐modulated tripeptide coacervates mimic biomolecular condensates with controllable, enzyme‐regulated phase separation. They co‐sequester hydrophobic active species and hydrophilic enzymes, enabling tandem catalysis in aqueous media. Incorporated into artificial cells, they function as adaptive sub‐organelles, orchestrating compartmentalized ...

Advanced Materials, Volume 37, Issue 13, April 2, 2025.A single object with dual properties – degradable and non‐degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi‐material printing is enabled by the combination of a fully wavelength‐orthogonal photoresin and a monochromatic tunable laser printer, paving the way for precise multi‐material ...

Angewandte Chemie, EarlyView.A large variety of chemistry‐based ubiquitin probes have been developed. ABSTRACT Ubiquitin (Ub) and ubiquitin‐like proteins (Ubls) orchestrate diverse cellular processes through reversible post‐translational modification of target proteins. Their conjugation is governed by a cascade of E1 activating, E2 conjugating, and E3 ligating enzymes, while ...

Photochemical Fuel Carrier Molecules for Robotic Embodied Energy
Advanced Materials, EarlyView.We designed a novel fuel carrier photoresponsive molecule for on‐demand energy storage and release. Carrier molecules undergo bond scission under UV light to release chemical fuel and locally generate propulsive Marangoni flows. We demonstrate this photochemical embodied energy strategy in small‐scale robots and active matter systems, enabling ...

Biological activity of coumarin derivatives – a review
Croatian Journal of Food Science and Technology, 2011 Coumarin derivatives are wide spread in nature and found in many plants, fruits and vegetables. They show a broad spectrum of biological activities, but the use of coumarin is restricted by law and its maximal allowed concentration in foodstuff is ...
