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

International 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).

Conformational studies of free and Li+ complexed jasplakinolide, a cyclic depsipeptide from the Fijian marine sponge Jaspis splendens [PDF]

, 2005
The complexation of Li+ to jasplakinolide, a marine sponge derived cyclic depsipeptide showed preferential binding to two out of four carbonyl oxygens (C-10, C-14) and the electrons of the aromatic system of the β-tyrosine amino acid residue.

Anti-Parasitic Compounds from Streptomyces sp. Strains Isolated from Mediterranean Sponges

Marine Drugs, 2010
Actinomycetes are prolific producers of pharmacologically important compounds accounting for about 70% of the naturally derived antibiotics that are currently in clinical use. In this study, we report on the isolation of Streptomyces sp.

Hydroxamic Acids as HDAC Inhibitor Drug Leads for Malaria

Medicinal 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.

The mycotoxin definition reconsidered towards fungal cyclic depsipeptides

Journal of Environmental Science and Health, Part C, 2016
Currently, next to the major classes, cyclic depsipeptides beauvericin and enniatins are also positioned as mycotoxins. However, as there are hundreds more fungal cyclic depsipeptides already identified, should these not be considered as mycotoxins as well?

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

Pest 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.

Octreotide Conjugates for Tumor Targeting and Imaging

Pharmaceutics, 2019
Tumor targeting has emerged as an advantageous approach to improving the efficacy and safety of cytotoxic agents or radiolabeled ligands that do not preferentially accumulate in the tumor tissue. The somatostatin receptors (SSTRs) belong to the G-protein-

Advances in large DNA fragment assembly for microbial cell factory engineering

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

On-resin multicomponent 1,3-dipolar cycloaddition of cyclopentanone–proline enamines and sulfonylazides as an efficient tool for the synthesis of amidino depsipeptide mimics [PDF]

, 2020
Depsipeptides are biologically active peptide derivatives that possess a high therapeutic interest. The development of depsipeptide mimics characterized by a chemical diversity could lead to compounds with enhanced features and activity. In this work, an
