Study on the Antifungal Activity and Molecular Docking of Polyester Metabolites from Talaromyces striatoconidius [PDF]

open access: yesBiology
Plant pathogenic fungi seriously threaten global crop production, and endophytic fungi are promising reservoirs of bioactive antifungal metabolites. Three undescribed polyester derivatives, talapolyesters I–K (1–3), along with thirteen known compounds ...

Acid-base pair-mediated copolymerization of acid-sensitive epoxides and cyclic anhydride for synthesizing recyclable thermoplastics [PDF]

open access: yesNature Communications
Developing low-cost, high-performance, and chemically recyclable alternatives to bulk polyolefin commodities is critical. Aromatic polyesters synthesized via ring-opening copolymerization (ROCOP) of phthalic anhydride (PA) and olefin-derived epoxides are
