Phospholipase A2 inhibitor varespladib prevents wasp sting-induced nephrotoxicity in rats.
Toxicon, 2022This study aimed to clarify whether varespladib, a phospholipase A2 (PLA2) inhibitor, can be used as a therapeutic agent for wasp sting-induced acute kidney injury (AKI). Rats were divided into control, AKI, and AKI + varespladib groups. The AKI model was established by subcutaneously injecting wasp venom at five different sites in rats.

Snake venom protection by a cocktail of varespladib and broadly neutralizing human antibodies
CellSnake envenomation is a neglected tropical disease, with 600 species causing over 100,000 deaths and 300,000 permanent disabilities in humans annually. Broadly neutralizing antibodies and broad chemical inhibitors have been proposed as solutions, but how to develop a therapeutically effective cocktail and the number of required components have been ...

Varespladib (LY315920) is a synthetic phospholipase A2 (PLA2) inhibitor that has been demonstrating antiophidic potential against snake venoms that present PLA2 neurotoxins. In this study, we evaluate the capacity of Varespladib to inhibit the neuromuscular effects of crotoxin (CTX), the main toxic component of Crotalus durissus terrificus snake venom,

Anticoagulant toxicity is a common function of venoms produced by species within the Bitis genus. Potent inhibition of the prothrombinase complex is an identified mechanism of action for the dwarf species B. cornuta and B. xeropaga, along with some localities of B. atropos and B. caudalis.

Cardiovascular Toxicology, 2023
In this work, we examined the action of two South American coralsnake (Micrurus corallinus and Micrurus dumerilii carinicauda) venoms on rat heart function in the absence and presence of treatment with Brazilian coralsnake antivenom (CAV) and varespladib (VPL), a potent phospholipase A2 inhibitor. Anesthetized male Wistar rats were injected with saline

Varespladib methyl in cardiovascular disease
Expert Opinion on Investigational Drugs, 2010The high risk of recurrent cardiovascular events amongst patients with cardiovascular disease receiving evidence-based therapies has prompted investigations into complimentary treatments that may reduce residual risk. Analyses of clinical trials in statin-treated patients demonstrate that elevated lipid levels and an activated systemic inflammatory ...

The phospholipase A2 (PLA2) inhibitors varespladib (LY315920) and its orally available derivative methyl-varespladib (LY333013) have been proposed as potential therapies for the treatment of snakebite envenomings in which toxicity depends on the action of PLA2s.

Secretory phospholipase A2 (sPLA2), which links surfactant catabolism and lung inflammation, is associated with lung stiffness, surfactant dysfunction, and degree of respiratory support in acute respiratory distress syndrome and in some forms of neonatal lung injury. Varespladib potently inhibits sPLA2 in animal models.

Snakebite envenomation often leads to severe visceral injuries, including acute liver injury (ALI). However, the toxicity mechanism remains unclear. Moreover, varespladib can directly inhibit phospholipase A2 (PLA2) in snake venom, but its protective effect on snakebite-induced ALI and the mechanism have not been clarified.

Surfactant and Varespladib Co-Administration in Stimulated Rat Alveolar Macrophages Culture
Current Pharmaceutical Biotechnology, 2013Acute lung injury is a life-threatening condition characterized by surfactant dysfunction and raised secretory phospholipase A2 (sPLA2) activity. Varespladib is a sPLA2 inhibitor shown to be effective in animal models of acute lung injury. We aimed at investigating the effect of co-administration of surfactant and varespladib on sPLA2 activity ...
