A Cationic Supramolecule With Potent Antifungal Activity, Single‐Species Selectivity, and Strong Synergy With Echinocandins

open access: yesAdvanced Science, EarlyView.
We introduce a new membrane‐active antifungal design, Gua‐SMACS‐16, that exhibits high potency and single‐species selectivity for C. tropicalis while sparing other close species in the Candida genus. Moreover, when combining with caspofungin, a clinical antifungal drug inhibiting 1,3‐β‐glucan synthase, they exhibit ultra‐strong synergy across a panel ...

Über Kumulene, XII. cis-Polyene durch Partialhydrierung von Kumulenen

open access: yes, 1960
Die katalytische Hydrierung von Kumulenen mit dem Lindlar-Katalysator liefert die entsprechenden Polyene. In den dafür in Frage kommenden Fällen erhielt man dabei noch unbekannte cis-Polyene, die sich durch Belichtung in die schon bekannten trans-Polyene

Räumliche Entwicklung von Koks in ZSM‐5‐Katalysatoren während der Umwandlung von Methanol in Kohlenwasserstoffe, aufgezeigt durch in‐situ‐Röntgen‐Photoelektronenspektroskopie

open access: yesAngewandte Chemie, EarlyView.
Oberfläche enthüllt: Verkokung ist die zentrale Ursache für die Deaktivierung von Zeolithkatalysatoren. Mithilfe von In‐situ‐XPS in Verbindung mit ergänzenden Methoden identifizieren wir Unterschiede in der Bildungskinetik und Zusammensetzung von Oberflächenkoks auf industriell relevanten ZSM‐5‐Katalysatoren während der MTH‐Umwandlung und zeigen damit ...

An Amphotericin B Derivative Equally Potent to Amphotericin B and with Increased Safety. [PDF]

open access: yesPLoS ONE, 2016
Amphotericin B is the most potent antimycotic known to date. However due to its large collateral toxicity, its use, although long standing, had been limited. Many attempts have been made to produce derivatives with reduced collateral damage.
