Cantharidin: potent feeding deterrent to insects
Science (New York, N.Y.)
|February 22, 1974
Summary
Cantharidin, a compound from blister beetles, deters insect feeding. This natural terpenoid is effective at very low concentrations, showing its potential as an insect repellent.
Area of Science:
- Chemical Ecology
- Entomology
- Natural Products Chemistry
Background:
- Cantharidin is a toxic terpenoid derived from blister beetles.
- It is known as the active principle in Spanish fly.
- Cantharidin has potential applications due to its biological activity.
Purpose of the Study:
- To investigate the efficacy of cantharidin as an insect feeding deterrent.
- To determine the effective concentration of cantharidin for insect deterrence.
Main Methods:
- Chemical analysis of blister beetle secretions.
- Bioassays to assess insect feeding behavior in the presence of cantharidin.
Main Results:
- Cantharidin acts as a potent feeding deterrent to insects.
- Effectiveness was observed at a concentration of 10(-5) molar.
Conclusions:
- Cantharidin is a naturally occurring compound with significant insect repellent properties.
- Its low effective concentration suggests potential for developing natural insecticides.

01:10Drugs that Destabilize Microtubules
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
01:17Antidotes
Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...

01:17Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action
Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...

01:27Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions
Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.

01:28Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates these...
01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
