Evaluation of In Vitro Anti-inflammatory Activity of Azomethines of Aryl Oxazoles

E-Journal of Chemistry, 2011
Ability to inhibit erythrocyte hemolysis is often used as a characteristic of the membrane stabilising action of chemical compounds. Azomethines of aryl oxazoles were evaluated for anti-inflammatory by in vitro hemolytic membrane stabilising study.

Funktionalisierung von Peptiden auf der festen Phase im späten Synthesestadium

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Peptidmodifikationen sind für die Kontrolle der Eigenschaften von Peptidwirkstoffen von entscheidender Bedeutung. Daher sind Strategien, die einen effizienten und schnellen Einbau nicht‐kanonischer Modifikationen in Peptide in Parallelformaten ermöglichen, sehr gefragt.

Aromaticities of Five Membered Heterocycles through Dimethyldihydropyrenes Probe by Magnetic and Geometric Criteria

Journal of Chemistry, 2015
Aromaticities of five membered heterocycles, containing up to three heteroatoms, are quantified through the dimethyldihydropyrene (DHP) probe. Bond fixation caused by the fusion of heterocycles to the dimethyldihydropyrene nucleus (DHPN) was measured by ...
