Synthesis of 2‐(Trifluoromethyl)Azetidines by Strain‐Release Reactions of 2‐(Trifluoromethyl)‐1‐Azabicyclo[1.1.0]Butanes

Chemistry – A European Journal, EarlyView.
2‐(Trifluoromethyl)‐1‐azabicyclo[1.1.0]butanes, available by diastereoselective cyclopropanation of 2‐(trifluoromethyl)‐2H‐azirines, can be successfully involved in strain‐release ring‐opening processes, as illustrated by their reaction with benzyl chloroformate, trifluoroacetic anhydride or palladium‐catalyzed hydrogenolysis.

Solvent‐free Process for Preparing Metal‐organic Framework Composites based on Carbon‐based Quantum Dots and their Derivatives as Drug Delivery Systems for Andrographolide

Chemistry – A European Journal, Accepted Article.
Andrographolide (ADG) was conjugated with MIL‐53(Al), ZIF‐8, carbon‐based quantum dots (CBQDs) and doped carbon‐based quantum dots (D‐CBQDs) using high‐pressure (0.3 GPa) contact. This solvent‐free approach is environmentally friendly, energy‐efficient and time‐saving, resulting in ADG‐MOFs‐CBQDs/D‐CBQDs with physical properties comparable to those ...

In vitro screening and in vivo evaluation of antiparasitic phytochemicals against Cryptocaryon irritans in pompano, Trachinotus ovatus

Journal of the World Aquaculture Society, Volume 53, Issue 6, Page 1084-1100, December 2022., 2022
Abstract Cryptocaryon irritans, one of the most devastating holotrichous ciliated protozoans, causes massive economic losses in the pompano, Trachinotus ovatus, mariculture industries. Considering the many advantages of phytochemicals, such as low cost, low residuals, and low pollution, they can be a good alternative for the prevention and control of C.

Integrating Catalysis and Analysis: Accelerated Asymmetric Reaction Development with a Multitasking Reactivity Umpolung/Chiroptical Reporter Auxiliary

Chemistry – A European Journal, Accepted Article.
High‐throughput asymmetric reaction development of an organocatalytic Michael addition is achieved by using a readily available isatin molecule as amine protecting group, reagent for reactivity Umpolung, and as chiroptical yield and enantioselectivity reporter.

Lewis‐X‐Containing Triterpenoid Saponins Inhibit DC‐SIGN‐ and L‐SIGN‐Mediated Transfer of HIV‐1 Infection

Chemistry – A European Journal, EarlyView.
The convergent synthesis of Lewis‐X‐containing betulinic acid and echinocystic acid saponins (1 and 2) is presented. The synthetic saponins were shown to inhibit, at the low micromolar range, the DC‐SIGN‐ and L‐SIGN‐mediated transfer of HIV‐1 infection to CD4‐positive cells, whereas free Lewis‐X, aglycones, and structurally similar triterpenoid ...

Membran‐Bioreaktor‐Technik kombiniert mit nachgeschalteter Ozonung – Vergleich mit konventionellen Ozonanwendungen Combination of Membrane Bioreactor and Downstream Ozonation – A Comparison to Conventional Ozone Applications

Chemie Ingenieur Technik, EarlyView.
Kommunale Kläranlagen gelten als Haupteintragspfad organischer Mikroschadstoffe in die aquatische Umwelt. Ein Großteil der Arzneimittelrückstände und Industriechemikalien wird in Kläranlagen nicht oder nur teilweise entfernt. Um einen qualitativ höheren Kläranlagen‐Ablauf zu erzeugen, wird eine Kombination aus hybridem Teilstrom‐Membran‐Bioreaktor mit ...
