GOT1 Inhibition Induces Extracellular Matrix Remodeling in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Using tumor tissue engineering, we recreated pancreatic cancer and found that inhibiting glutamic‐oxaloacetic transaminase 1 (GOT1) induces extracellular matrix remodeling and secretome rewiring, as well as promotes cell death. ABSTRACT Pancreatic cancer cells rely on glutamine to sustain their survival in the stiff and poorly vascularized tumor ...

The crystal structure of 1-(2-iodobenzoyl)-4-(pyrimidin-2-yl)piperazine: a three-dimensional hydrogen-bonded framework, augmented by π–π stacking interactions and I...N halogen bonds

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2019
In 1-(2-iodobenzoyl)-4-(pyrimidin-2-yl)piperazine, C15H15IN4O, the central piperazine ring adopts an almost perfect chair conformation with the pyrimidine substituent in an equatorial site.

Functional and genetic evidence that nucleoside transport is highly conserved in Leishmania species: Implications for pyrimidine-based chemotherapy [PDF]

open access: yes, 2017
Leishmania pyrimidine salvage is replete with opportunities for therapeutic intervention with enzyme inhibitors or antimetabolites. Their uptake into cells depends upon specific transporters; therefore it is essential to establish whether various ...

Abiotic synthesis of purine and pyrimidine ribonucleosides in aqueous microdroplets

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance Discovery of an improved prebiotic method for the synthesis of ribonucleosides provides support to theories that posit a central role for RNA in the origin of life. It has been assumed that ribonucleosides arose through an abiotic process in

Acceptor‐Bridged Engineering Enables Highly Efficient Solution‐Processed Pure‐Green MR‐TADF OLEDs With External Quantum Efficiency of 29% and Small Roll‐Off

open access: yesAdvanced Science, EarlyView.
Solution‐processible pure green multi‐resonance thermally activated delayed fluorescence (MR‐TADF) emitters are developed through a strategic acceptor‐bridging engineering approach that integrates MR‐building blocks with pyrimidine‐derived frameworks.

Orotic Aciduria [PDF]

open access: yes, 2018
Orotic acid is an intermediate found in the pathway for pyrimidine synthesis. The mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) catalyzes the production of orotic acid by the conversion of the compound dihydroorotate to orotic acid.

Untersuchungen zum Ursprung der Substratspezifität von Enzymen der Amidohydrolase‐Superfamilie

open access: yesAngewandte Chemie, EarlyView.
Umfassende Analysen zweier Enzymklassen aus der Amidohydrolase‐Superfamilie (AHS) ergaben, dass die Katalyse über eine 1,4‐ bzw. 1,6‐nukleophile konjugierte Addition abläuft und diese Eigenschaft die Substratspezifität bestimmt. Obwohl alle Substrate und Produkte vollständig achiral sind, führt dieser mechanistische Unterschied zu einer invertierten ...

Three Dimensional Quantitative Structure-Activity Relationships of Sulfonamides Binding Monoclonal Antibody by Comparative Molecular Field Analysis [PDF]

open access: yes, 2008
The three-dimensional quantitative structure-activity relationship (3D-QSAR) model of sulfonamide analogs binding a monoclonal antibody (MabSMR) produced against sulfamerazine, was carried out by comparative molecular field analysis (CoMFA).
