Metabolomics reveals the heterogeneous secretome of two entomopathogenic fungi to ex vivo cultured insect tissues. [PDF]

open access: yesPLoS ONE, 2013
Fungal entomopathogens rely on cellular heterogeneity during the different stages of insect host infection. Their pathogenicity is exhibited through the secretion of secondary metabolites, which implies that the infection life history of this group of ...

Lyngbyastatins 8–10, Elastase Inhibitors with Cyclic Depsipeptide Scaffolds Isolated from the Marine Cyanobacterium Lyngbya semiplena

open access: yesMarine Drugs, 2009
Investigation of an extract from the marine cyanobacterium Lyngbya semiplena, collected in Tumon Bay, Guam, led to the identification of three new cyclodepsipeptides, lyngbyastatins 8–10 (1–3).

Production of destruxins from Metarhizium spp. fungi in artificial medium and in endophytically colonized cowpea plants. [PDF]

open access: yesPLoS ONE, 2014
Destruxins (DTXs) are cyclic depsipeptides produced by many Metarhizium isolates that have long been assumed to contribute to virulence of these entomopathogenic fungi.

Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A

open access: yesAngewandte Chemie, Volume 138, Issue 26, 22 June 2026.
Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

open access: yesChemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Diarylethene‐Containing Photoswitchable Analogues of Tubulysins—Design, Synthesis, Biological, and Structural Evaluation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Diarylethene‐containing cyclic tubulysin analogues were designed, synthesized, and evaluated as light‐responsive cytotoxic agents. One analogue showed reversible photoswitching, photoregulated tubulin polymerization inhibition, and photoform‐dependent cytotoxicity.

Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1–5 and Therapeutic Implications in Neuroendocrine and Non‐Neuroendocrine Malignancies

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

Hydroxamic Acids as HDAC Inhibitor Drug Leads for Malaria

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a global health threat, with an estimated 282 million cases and 610,000 malaria‐associated deaths reported in 2024. Most mortality is due to infection by Plasmodium falciparum parasites, with the highest burden occurring in Sub‐Saharan Africa.

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

open access: yesPest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.
