Catellatolactams A–C (1–3), three novel ansamacrolactams, were isolated from the culture
extract of an underexplored rare actinomycete of the genus Catellatospora. Spectroscopic …

Cytochrome P450 enzymes (P450s) catalyze diverse oxidative cross-coupling reactions
between aromatic substrates in the natural product biosynthesis. Specifically, P450s install …

We report our investigation of the utility of peptide crosslinking cytochrome P450 enzymes
from biarylitide biosynthesis to generate a range of cyclic tripeptides from simple synthons …

Microbial natural products impress by their bioactivity, structural diversity, and ingenious
biosynthesis. While screening the less exploited actinobacterial genus Planomonospora …

Cyclization of linear peptides is an effective strategy to convert flexible molecules into rigid
compounds, which is of great significance for enhancing the peptide stability and bioactivity …

Ribosomally synthesized and post-translationally modified peptides (RiPPs) are a large
class of secondary metabolites that have garnered scientific attention due to their complex …

After the successful discoveries of numerous antibiotics from microorganisms, frequent
reisolation of known compounds becomes an obstacle in further development of new drugs …

Two new chloropyrroles, designated catellatopyrroles A (1) and B (2), along with 2-(2′-
