Protease inhibitor in scorpion (Mesobuthus eupeus) venom prolongs the biological activities of the crude venom.

It is hypothesized that protease inhibitors play an essential role in survival of venomous animals through protecting peptide/protein toxins from degradation by proteases in their prey or predators. However, the biological function of protease inhibitors in scorpion venoms remains unknown. In the present study, a trypsin inhibitor was purified and characterized from the venom of scorpion Mesobuthus eupeus, which enhanced the biological activities of crude venom components in mice when injected in combination with crude venom.

A Designed Tryptophan- and Lysine/Arginine-Rich Antimicrobial Peptide with Therapeutic Potential for Clinical Antibiotic-Resistant Candida albicans Vaginitis.

New therapeutic agents for Candida albicans vaginitis are urgently awaiting to be developed because of the increasing antibiotic resistance of C. albicans. Antimicrobial peptides (AMPs) are one of the most promising choices for next-generation antibiotics.

Centipede venoms and their components: resources for potential therapeutic applications.

Venomous animals have evolved with sophisticated bio-chemical strategies to arrest prey and defend themselves from natural predators. In recent years, peptide toxins from venomous animals have drawn considerable attention from researchers due to their surprising chemical, biochemical, and pharmacological diversity. Similar to other venomous animals, centipedes are one of the crucial venomous arthropods that have been used in traditional medicine for hundreds of years in China.

Scorpion Toxin, BmP01, Induces Pain by Targeting TRPV1 Channel.

The intense pain induced by scorpion sting is a frequent clinical manifestation. To date, there is no established protocol with significant efficacy to alleviate the pain induced by scorpion envenomation. One of the important reasons is that, little information on pain-inducing compound from scorpion venoms is available.

Two new types of allergens from the cockroach, Periplaneta americana.

Periplaneta americana cockroach is an important source of inhalant indoor allergen resource, and there are more than twenty IgE-binding components identified in P. americana, but only nine allergens were characterized. Our knowledge about cockroach allergens remains poor.
