Conformational Re-engineering of Porphyrins as Receptors with Switchable NH???X-Type Binding Modes
Senge, Mathias; Norvaiša, Karolis; Flanagan, Keith J.; Gibbons, Dáire (2019)The selectivity and functional variability of porphyrin cofactors are typically based on substrate binding of metalloporphyrins wherein the pyrrole nitrogen units only serve to chelate the metal ions. Yet, using the porphyrin ... -
Functionalization of Deutero- and Protoporphyrin IX Dimethyl Esters via Palladium-Catalyzed Coupling Reactions
Senge, Mathias; O'Brien, Jessica; Sitte, Elisabeth; Flanagan, Keith J.; Kühner, Hannes; Hallen, Lukas J.; Gibbons, Dáire (2019)Herein, we report the functionalization of the β-positions of deutero- and protoporphyrin IX dimethyl ester. Initial halogenations were carried out on both deutero- and protoporphyrin IX dimethyl ester. While previously ... -
Structure and conformation of photosynthetic pigments and related compounds. 15. Conformational analysis of chlorophyll derivatives-implications for hydroporphyrins in vivo
Senge, Mathias; Gibbons, Dáire; Flanagan, Keith J.; Pounot, Léa (2019)Chlorophylls are fundamental macrocyclic cofactors in photosynthetic reaction centers and light‐harvesting complexes. Their biological function is well understood on the basis of protein structural data and a significant ...
