Biologically active phenol and indole derivatives of terrestrial arthropods: electrophy­sio­logical and chemical characteristics

Біологічні студії, 2019
Toxins-antagonists of glutamatergic synapses were found in venoms of different terrestrial Arthrpopodae, both Insecta and Aranei. Chemical structures of some of them were described, and a majority of such substances are derivatives of phenol and indole ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Two Novel Peptide Toxins from the Spider Cyriopagopus longipes Inhibit Tetrodotoxin-Sensitive Sodium Channels

, 2020
Sodium channels play a critical role in the generation and propagation of action potentials in excitable tissues, such as nerves, cardiac muscle, and skeletal muscle, and are the primary targets of toxins found in animal venoms.

Multi‐Omics Analyses Elucidate the Venom Components of the Wasp Vespa mandarinia

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The wasp Vespa mandarinia was widely reared in Yunnan province. The venom was responsible for their aggressive behavior. Tweety proteases, hyaluronidase, venom dipeptidyl peptidase 4, and phospholipase A1 and A2 isozyme were identified. In addition, organic heterocyclic compounds, organic acids, and derivatives were found.

Tandem mass spectrometric investigation of acylpolyamines of spider venoms and their 15N-labeled derivatives [PDF]

, 2004
The fragmentation mechanism of the acylpentamine toxins 1–4 found in the venom of the spider Agelenopsis aperta has been investigated in detail. To identify the origin of the two doublets of unexpected fragment ions at m/z 129/112 and m/z 115/98, three ...

Venomic and pharmacological activity of Acanthoscurria paulensis (Theraphosidae) spider venom

Toxicon, 2013
In the present study we conducted proteomic and pharmacological characterizations of the venom extracted from the Brazilian tarantula Acanthoscurria paulensis, and evaluated the cardiotoxicity of its two main fractions. The molecular masses of the venom components were identified by mass spectrometry (MALDI-TOF-MS) after chromatographic separation ...
