Exploring the Substitution of the C21‐OAc Moiety in [11]Cytochalasans: Synthesis and Evaluation of Fluorophore Conjugates

open access: yesChemBioChem, Volume 27, Issue 1, January 2026.
Via in silico docking of pyrichalasin H on G‐ and F‐actin, the C21‐OAc moiety is identified as a modifiable site tolerated for actin binding. Fluorescent [11]cytochalasan probes from pyrichalasin H and epoxycytochalasin C are obtained by selective C21‐OAc hydrolysis and acylation.

Mining Actinomycetes' Metabolomes and Genomes for Anti‐Phytophthora infestans Compounds

open access: yesMicrobial Biotechnology, Volume 18, Issue 12, December 2025.
Using a comparative metabolomic and genomic approach on 63 actinomycetes, this study identified 75 compounds associated with the strains' ability to inhibit the late blight‐causing agent Phytophthora infestans. This study highlighted the promise of applying multi‐omics techniques on closely related strains differing in biological activity to pinpoint ...

Environmental Requirements for Germination and Appressorium Formation of Ascospores and Conidia of Phyllosticta citricarpa, the Causal Agent of Citrus Black Spot

open access: yesPlant Pathology, Volume 74, Issue 7, Page 2108-2120, September 2025.
Cardinal temperatures for both Phyllosticta citricarpa spore germination were estimated as ~10ºC (minimum) and ~40ºC (maximum), and the optimum temperatures were ~30ºC for ascospores and ~24ºC for conidia. ABSTRACT Phyllosticta citricarpa produces ascospores and conidia that infect citrus tissues and cause citrus black spot (CBS).

The herbicidal natural product phosphonothrixin is an inhibitor of the riboflavin biosynthetic enzyme L‐3,4‐dihydroxy‐2‐butanone‐4‐phosphate synthase

open access: yesPest Management Science, Volume 81, Issue 8, Page 4328-4335, August 2025.
An enzyme involved in vitamin B2 biosynthesis, 3,4‐dihydroxy‐2‐butanone‐4‐phosphate synthase (DHBPS), was identified as the target of the natural product phosphonothrixin, representing a novel mode of action for herbicides. Abstract BACKGROUND In our ongoing search for new and environmentally friendly chemical entities that can control weeds via new ...
