Modeling and molecular dynamics indicate that snake venom phospholipase B-like enzymes are Ntn-hydrolases

Phospholipase B in snake venoms and bee venom.

Angiostatin-like molecules are generated by snake venom metalloproteinases.

Angiostatin is a plasminogen-derived anti-angiogenic factor composed of its first four kringle structures. This molecule is generated by proteolytic cleavage of plasminogen by some proteolytic enzymes in vitro. Since venoms of viper snakes are a rich source of both serine- and metalloproteinase, we hypothesized that angiostatin-like polypeptides could be generated during the envenomation after ...

Snake Venom, Anti-snake Venom & Potential of Snake Venom

Many active secretions produced by animals have been employed in the development of new drugs to treat diseases such as hypertension and cancer. Snake venom toxins contributed significantly to the treatment of many medical conditions. Venomous snakes have a bad reputation and rightly so because of their often deadly bites. But what makes a snake’s bite so deadly is the venom. Of the 3000 snake ...

Therapeutic application of natural inhibitors against snake venom phospholipase A2

Natural inhibitors occupy an important place in the potential to neutralize the toxic effects caused by snake venom proteins and enzymes. It has been well recognized for several years that animal sera, some of the plant and marine extracts are the most potent in neutralizing snake venom phospholipase A(2) (svPLA(2)). The implication of this review to update the latest research work which has be...

Quercetin as an inhibitor of snake venom secretory phospholipase A2.

As polyphenolic compounds isolated from plants extracts, flavonoids have been applied to various pharmaceutical uses in recent decades due to their anti-inflammatory, cancer preventive, and cardiovascular protective activities. In this study, we evaluated the effects of the flavonoid quercetin on Crotalus durissus terrificus secretory phospholipase A2 (sPLA2), an important protein involved in t...
