| Avermectin | Avermectin. Uses: For analytical and research use. Group: Impurity standards. CAS No. 71751-41-2. Molecular Formula: C49H74O14. Mole Weight: 887.12. Catalog: APB71751412. |  |
| Avermectin A1a | Avermectin A1a is produced by the strain of Streptomyces avermitilis. It stimulates nerve cells to release Y-aminobutyric acid (GABA), which blocks the transmission of signals from the central nervous system to the motor nerve. It is not resistant to bacteria and fungi, but has strong activity to nematode parasites such as ancylostoma and Pteria, as well as insects such as flies. Abamectin B1a has the highest activity. Ivermectin obtained by catalytic hydrogenation contains 22 23- dihydroabamectin B1a (above 80%) and 22 23 dioxabamectin B1b (below 20%). Less active than B1a but less toxic. Used as repellent (subcutaneous or oral) for cattle, sheep and pigs, it is also effective against human filariasis. Synonyms: SCHEMBL1681257. CAS No. 65195-51-9. Molecular formula: C49H74O14. Mole weight: 887.10. |  |

| Doramectin (25-Cyclohexyl-5-O-demethyl-25-de (1-methylpropyl) avermectin A1A,. 25-Cylohexyl-avermectin B1, UK-67994, Dectomax) | Doramectin is a biosynthetic avermectin derived from a mutant of the original Streptomyces avermitilis strain supplemented with a cyclohexylcaboxylic acid starting unit. Doramectin was developed as an anthelmintic for internal parasite control. The presence of the cyclohexyl group replacing the sec-butyl moiety affords greater hydrophobicity and longer biological half-life compared to avermectin. Like the other milbemycin / avermectins, it selectively binds to parasite glutamate-gated chloride ion channels and disrupts neurotransmission leading to paralysis and death of the parasite. Group: Biochemicals. Alternative Names: 25-Cyclohexyl-5-O-demethyl-25-de (1-methylpropyl) avermectin A1A; 25-Cylohexyl-avermectin B1; UK-67994; Dectomax. Grades: Highly Purified. CAS No. 117704-25-3.

| Doramectin | Doramectin is a biosynthetic avermectin derived from a mutant of the original Streptomyces avermitilis strain supplemented with a cyclohexylcaboxylic acid starting unit. Doramectin was developed as an anthelmintic for internal parasite control. The presence of the cyclohexyl group replacing the sec-butyl moiety affords greater hydrophobicity and longer biological half-life compared to avermectin. Like the other milbemycin / avermectins, it selectively binds to parasite glutamate-gated chloride ion channels and disrupts neurotransmission leading to paralysis and death of the parasite.

| Milbemycin Oxime | Milbemycin oxime is a semi-synthetic macrocyclic lactone prepared by the oxidation and oximation of a mixture of two natural products, milbemycin A3 and A4 (in ~70: 30 ratio). Moxidectin oxime, marketed as Interceptor, is used therapeutically for the prevention of intestinal parasites in dogs. Like the other milbemycin / avermectins, it was developed for intestinal parasite control in animals and acts by opening glutamate sensitive chloride channels in neurons of invertebrates leading to paralysis by hyperpolarisation of these cells and signal transfer blocking. Group: Biochemicals. Grades: Highly Purified. CAS No. 129496-10-2. Pack Sizes: 5mg. US Biological Life Sciences. | Worldwide |
