Endoparacitiides Flashcards
8 classes of pre-2000 Endoparaciticides
Organophsophatates
Benzimidazole
Salicylanilides
Pyrazinoisoquinolones
Sulphonamides
Tetrahydropyramidines/ imidazothiazoles
Hexahydropyrazine
Macrolytic lactones
3 post-2000 endoparasitics
Cyclic Octadepsipeptide
Aminoacetonitrile derivative
Spioinidole
3 examples of organophosphates
Dichlorvos
Haloxon
Naphalofos
8 examples of Benzimidazoles
- Albendazole
- Febantel
- Fenbendazole
- Flubendazole
- Mebendazole
- Oxfendazole
- Oxibendazole
- Thiabendazole
Target and action of bendizamadole
Bind to B-tubulin
- inhibition/blockage of polymerization (assembly of dimers)
-> abnormal microtubule formation and disrupts intracellular homeostasis and energy metabolism
2 examples of salicyanilides
Closantel
Rafoxanide
2 examples of pyrazinoisoquinolones
Praziquantel
Epsiprantel
Example of sulphonamide
Clorsulon
Example of Tertrahydropryamidines/imidazothiazole
Levamisole
Morantel
Pyrantel
Oxantel
Action of tetrahydropyridines/imidazothiazoles
Excitatory to the Nicotinic acetylcholine receptor
-> contraction-> spastic paralysis of the worms
2 Examples of Hexahydropyrazine
piperazine and its derivative diethycarbamazine
7 examples of macrolytic lactones
abamectin
Doramectin
Eprinomectin
Ivermectin
Moxidectin
Milbemycin oxime
Selamectin
Target and action of macrocytic lactones
Target: GABA receptor and glutamate-gated chloride channel
Action: Flaccid paralysis of worms, GABA and Glutamate are inhibitory
2 examples of cyclic octadepsipeptide
Nitroxynil
Emodepside
Action of cyclic octadespitpetide
Acts on specific class of transmembrane G-protein coupled receptors (GPCRs, desiphillins)
Iatrophillin receptor class
