Identification and Venom Characterization of Two Scorpions from the State of Chihuahua Mexico: Chihuahuanus coahuliae and Chihuahuanus crassimannus

Toxins, 2023
Chihuahua is the largest state in Mexico. The ecosystem of this region is composed of large area of bushes, forests, and grasslands, which allows for a specific diversity of fauna; among them are interesting species of non-lethal scorpions.

The myth of scorpion suicide: are scorpions insensitive to their own venom? [PDF]

Journal of Experimental Biology, 1998
ABSTRACT The resistance of the scorpion Androctonus australis to its own venom, as well as to the venom of other species, was investigated. A comparison of the electrical and pharmacological properties of muscle and nerve fibres from Androctonus australis with those from the crayfish Procambarus clarkii enabled us to understand the lack ...

Venomics of the scorpion Tityus ocelote (Scorpiones, Buthidae): Understanding venom evolution in the subgenus Archaeotityus

International Journal of Peptide Research and Therapeutics, 2022
AbstractThe subgenusTityus (Archaeotityus)includes small variegated species considered until recently, a basal group withinTityus, one of the most diverse and medically relevant genera of scorpions in the New World.Archaeotityusspecies are distributed in the humid forests of Lower Central America and the Choco, Guiana Shield, and Amazon regions. Due to

Anticoagulant Activity of Low-Molecular Weight Compounds from Heterometrus laoticus Scorpion Venom

Toxins, 2017
Scorpion venoms are complex polypeptide mixtures, the ion channel blockers and antimicrobial peptides being the best studied components. The coagulopathic properties of scorpion venoms are poorly studied and the data about substances exhibiting these ...

Hyperpolarization Modulation of the T‐Type hCav3.2 Channel by Human Synenkephalin [1–53], a Shrew Neurotoxin Analogue without Paralytic Effects

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Human synenkephalin [1–53] (hSYN), an analogue peptide of shrew saliva neurotoxins, was synthesized and its structural characteristics studied. Synthetic hSYN potently activated the T‐type voltage‐gated Ca channel hCav3.2 but did not paralyze mealworms. These findings offer new insight into neurological disorder treatment and evolutionary mechanisms of

Terrestrial venomous animals, the envenomings they cause, and treatment perspectives in the Middle East and North Africa.

PLoS Neglected Tropical Diseases, 2021
The Middle East and Northern Africa, collectively known as the MENA region, are inhabited by a plethora of venomous animals that cause up to 420,000 bites and stings each year. To understand the resultant health burden and the key variables affecting it,

Protease inhibitors from marine venomous animals and their counterparts in terrestrial venomous animals [PDF]

, 2013
The Kunitz-type protease inhibitors are the best-characterized family of serine protease inhibitors, probably due to their abundance in several organisms.
