Atroposelective Access to Bicyclic Peptides via an Amide Photocaging Strategy

open access: yesAngewandte Chemie International Edition, EarlyView.
Ansamers are an atypical class of atropisomers (Pansa/Mansa) and stereoselective synthesis of its two conformational isomers is challenging. We introduce a photocaged amide protection strategy: photolabile groups in monocycles reversibly modulate amide geometry, biasing macrolactamization to selectively give Pansa or Mansa.

Novel Macrocyclic Amidinoureas: Potent Non-Azole antifungals active against wild-type and resistant Candida species

open access: yes, 2013
Novel macrocyclic amidinourea derivatives 11, 18, and 25 were synthesized and evaluated as antifungal agents against wild-type and fluconazole resistant Candida species. Macrocyclic compounds 11 and 18 were synthesized through a convergent approach using

The Preparation of Macrocyclic Diester and Tetraester Ligands by a Transesterification Process [PDF]

open access: yes, 1986
This short review summarizes the synthesis of macrocyclic diester and tetraester crown Iigands by a transesterification process. Compared with the previous method using a diacid chloride, this method is especially effective for the synthesis of ...

A Water‐Soluble Cycloparaphenylene: Supramolecular Receptor with Visible Fluorescence

open access: yesChemistryEurope
We report the first synthesis of a water‐soluble [9]cycloparaphenylene derivative containing three hydrindacene (1,2,3,5,6,7‐hexahydro‐s‐indacene) units with four carboxylates at the 2,6‐positions via a macrocyclic gold complex.

Biocatalysts for Peptide Geranylation With Linear and Cyclic Prenyl Groups

open access: yesAngewandte Chemie International Edition, EarlyView.
A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids.

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

open access: yesAnimal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...
