Cyclo19,31[D-Cys19]-uPA19-31 is a potent competitive antagonist of the interaction of urokinase-type plasminogen activator with its receptor (CD87) [PDF]
, 2001 Urokinase-type plasminogen activator (uPA) represents a central molecule in pericellular proteolysis and is implicated in a variety of physiological and pathophysiological processes such as tissue remodelling, wound healing, tumor invasion, and ...

Stereoisomerism and Conformational Directionality (Prelog Lecture)
CHIMIA, 1986 The inaugural Prelog Lecture provides me with a unique opportunity to pay tribute to a great scientist, teacher, and friend. As I hope to show, the work of Vladimir Prelog is profoundly relevant to the work that I want to describe today.

Comptes Rendus. Chimie, 2021 Out-of-plane deformations of metalloporphyrin skeletons have been well documented as playing important roles in relevant biological processes. In contrast, out-of-plane binding to the N-core of large metal cations as period 6 post-transition elements has

Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis. [PDF]
, 2016 The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the

Computational exploration of the chemical structure space of possible reverse tricarboxylic acid cycle constituents [PDF]
, 2017 The reverse tricarboxylic acid (rTCA) cycle has been explored from various standpoints as an idealized primordial metabolic cycle. Its simplicity and apparent ubiquity in diverse organisms across the tree of life have been used to argue for its antiquity

Analysis of cis-isomer-enriched dihydroquercetin sample by 1D and 2D NMR spectroscopy
Разработка и регистрация лекарственных средствIntroduction. The structure of dihydroquercetin (DHQ) is characterized by two chiral centers at positions 2 and 3 of the benzopyran cycle, resulting in possible diastereomers: trans- and cis-isomers.

Angewandte Chemie, EarlyView.We develop new bifacial chiral non‐fullerene acceptors (NFAs) for organic solar cells (OSCs). Through comparative investigations of four NFAs including meso, racemic, and chiral entries, we demonstrate the superiority of homochiral NFAs for the first time.
