Comparative study of synthetic peptides corresponding to region 115-129 in Lys49 myotoxic phospholipases A2 from snake venoms
(2003)
Lys49 phospholipase A2 homologues constitute a group of catalytically-inactive proteins, present in the venoms of many
crotalid snakes, which induce myonecrosis. Current evidence supports the mapping of their toxic site ...
Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus
(2014-12)
Four disintegrins were isolated from the venoms of the Central American viperid snakes Atropoides mexicanus (atropoimin), Bothrops asper (bothrasperin), Cerrophidion sasai (sasaimin), and Crotalus simus (simusmin). ...
Isolation of two basic phospholipases A2 from Bothrops diporus snake venom: comparative characterization and synergism between Asp49 and Lys49 variants
(2019)
Bothrops diporus, previously considered a subspecies of the B. neuwiedi complex, is a medically relevant viperid in
Northeastern Argentina. The venom of this species causes local tissue damage characterized by ...
Myotoxin-neutralizing peptides
PEPTIDES NEUTRALISANT LES MYOTOXINES
(2018-03-27)
The present invention relates to polypeptides having myotoxin-neutralizing properties and their use for treatment of envenomation. The present invention further relates to methods for neutralizing a venom using the polypeptide ...
Isolation and characterization of basic myotoxic phospholipases A2 from Bothrops godmani (Godman's pit viper) snake venom
(1992)
Two basic myotoxic phospholipases A2 were purified to homogeneity from the venom of Bothrops godmani from Costa Rica by ion-exchange chromatography on CM-Sephadex. They have molecular weights of 14,300 (myotoxin I) and ...
Estudio de la capacidad ofiófaga y la resistencia de la zopilota (Clelia clelia, Colubridae) de Costa Rica a los venenos de serpiente
(1982)
The resistance of the non-venomous snake Clelia clelia (Colubridae) to 13 venoms of both viperid and elapid snakes was tested. Specimens were subjected to natural bites by venomous snakes and were injected with measured ...
Varespladib (LY315920) and methyl Varespladib (LY333013) abrogate or delay lethality induced by presynaptically-acting neurotoxic snake venoms
(2020)
The phospholipase A2 (PLA2) inhibitor Varespladib (LY315920) and its orally bioavailable prodrug, methyl-Varespladib (LY333013) inhibit PLA2 activity of a wide variety of snake venoms. In this study, the ability of these ...
An Asp49 Phospholipase A2 from Snake Venom Induces Cyclooxygenase-2 Expression and Prostaglandin E2 Production via Activation of NF-κB, p38MAPK, and PKC in Macrophages
(2014)
Phospholipases A2 (PLA2) are key enzymes for production of lipid mediators. We previously demonstrated that a snake venom sPLA2 named MT-III leads to prostaglandin (PG)E2 biosynthesis in macrophages by inducing the expression ...
Serum antibody response to polysaccharides in children with recurrent respiratory tract infections
(2001)
We evaluated children (15-months old and older) with recurrent upper respiratory tract infections and normal
levels of immunoglobulins in serum for specific polysaccharide immunodeficiency using an enzyme-linked
immunosorbent ...
Immunochemical properties of the N-terminal helix of myotoxin II, a lysine-49 phospholipase A2 from Bothrops asper snake venom
(2001)
Myotoxic class II phospholipases A2 from snake venoms can be divided into Asp49 and Lys49 types. The latter, including
Bothrops asper myotoxin II, exert membrane damage despite lacking catalytic activity. A heparin-binding, ...
