Large Libraries of Structurally Diverse Macrocycles Suitable for Membrane Permeation

Christian Heinis, Alessandro Angelini, Alexander Lund Nielsen, Mischa Schüttel, Manuel Leonardo Merz, Xinjian Ji, Anne Sofie Luise Zarda, Ganesh Kumar Mothukuri, Zsolt Bognár, Edward Jeffrey Will

Macrocycles offer an attractive format for drug development due to their good binding properties and potential to cross cell membranes. To efficiently identify macrocyclic ligands for new targets, methods for the synthesis and screening of large combinator ...

Peptide-Hypervalent Iodine Reagent Chimeras: Enabling Peptide Functionalization and Macrocyclization

Jérôme Waser, Christian Heinis, Xinjian Ji, Xingyu Liu

Herein, we report a novel strategy for the modification of peptides based on the introduction of highly reactive hypervalent iodine reagents-ethynylbenziodoxolones (EBXs)-onto peptides. These peptide-EBXs can be readily accessed, by both solution- and soli ...

Cyclic Peptides for Drug Development

Christian Heinis, Alexander Lund Nielsen, Xinjian Ji

Cyclic peptides are fascinating molecules abundantly found in nature and exploited as molecular format for drug development as well as other applications, ranging from research tools to food additives. Advances in peptide technologies made over many years ...

De novo development of small cyclic peptides that are orally bioavailable

Maury Mariano Duany Benitez, Phoukham Phothirath, Khaled Il Khwildy, Christian Heinis, Alexander Lund Nielsen, Sevan Mleh Habeshian, Manuel Leonardo Merz, Xinjian Ji, Bo Li

Cyclic peptides can bind challenging disease targets with high affinity and specificity, offering enormous opportunities for addressing unmet medical needs. However, as with biological drugs, most cyclic peptides cannot be applied orally because they are r ...

Mechanistic study of the radical SAM-dependent amine dehydrogenation reactions

Xinjian Ji, Shuguang Yuan

The radical SAM enzyme NosL catalyzes the conversion of L-Trp to 3-methyl-2-indolic acid, and this reaction is initiated by the 5'-deoxyadenosyl (dAdo) radical-mediated hydrogen abstraction from the L-Trp amino group. We demonstrate here that when D-Trp wa ...
