Spider-Venom Peptides as Therapeutics
Spiders are the most successful venomous animals and the most abundant terrestrial predators. Their remarkable success is due in large part to their ingenious exploitation of silk and the evolution of pharmacologically complex venoms that ensure rapid subjugation of prey. Most spider venoms are dominated by disulfide-rich peptides that typically have high affinity and specificity for particular...
متن کاملSpider-Venom Peptides as Bioinsecticides
Over 10,000 arthropod species are currently considered to be pest organisms. They are estimated to contribute to the destruction of ~14% of the world's annual crop production and transmit many pathogens. Presently, arthropod pests of agricultural and health significance are controlled predominantly through the use of chemical insecticides. Unfortunately, the widespread use of these agrochemical...
متن کاملScorpion Venom as Therapeutic Agent - Current Perspective
Scorpions and their venoms have been employed in medication since thousands of years in Asia. The scorpion venom is an extremely advanced mixture of salts, nucleotides, biogenic amines, enzymes, mucoproteins, peptides and proteins (e.g. Neurotoxins). Scorpion venoms contain peptides that block or modify ion-channel function and present some doable applications to regulate cell excitability. Spe...
متن کاملIn vitro neutralization of the scorpion, Buthus tamulus venom toxicity.
Scorpion (Buthus tamulus) venom was subjected to neutralization by treating the venom with various chemicals such as hydrochloric acid, sodium hydroxide, thiourea, formaldehyde, zinc sulphate, acetic acid and trichloroacetic acid. The venom was also subjected to heat treatment. The levels of total protein, free amino acids and protease activity in neutralized venom decreased significantly. The ...
متن کاملVerified spider bites in Oregon (USA) with the intent to assess hobo spider venom toxicity.
This study compiled 33 verified spider bites from the state of Oregon (USA). The initial goal was to amass a series of bites by the hobo spider to assess whether it possesses toxic venom, a supposition which is currently in a contested state. None of the 33 bites from several spider species developed significant medical symptoms nor did dermonecrosis occur. The most common biters were the yello...
