| Ivermectin B1b | Ivermectin B1b is the minor component (>20%) of the commercial anthelmintic, ivermectin. Members of the avermectin/milbemycin anthelmintic class exert their anthelmintic effects by binding to glutamate-gated chloride channels expressed on nematode neurones and pharyngeal muscle cells. The avermectin/milbemycins are also potent insecticides. In vitro tests have found the B1b (25-iso-propyl) analogue to be slightly more potent than the 25-sec-butyl (B1a) analogue as an inhibitor of nematode larval development and paralysis and also a more sensitive probe for ivermectin resistance. Group: Biochemicals. Alternative Names: Ivermectin B1b, 22, 23-Dihydroavermectin B1b. Grades: Highly Purified. CAS No. 70209-81-3. Pack Sizes: 500ug, 2.5mg. US Biological Life Sciences. | Worldwide |

| Milbemycin A3 | Milbemycins are a complex family of macrocyclic lactones containing a highly characteristic spiroketal group produced by Streptomyces hydroscopicus subsp. aureolarcrimosus. Milbemycin A3 is the dominant member of a group of analogues containing a 25-methyl substituent. Milbemycin A3 is a highly selective and potent nematocide and insecticide. Like the closely related avermectins, milbemycins are thought to act on chloride-gated ion channels. Related to: Avermectin B1a, Avermectin B1b, Milbemycin A4, Milbemycin D, Nemadectin. Group: Biochemicals. Alternative Names: (6R,25R)-5-O-Demethyl-28-deoxy-6,28-epoxy-25-methylmilbemycin B; Spiro [11, 15-methano-2H, 7H, 13H-furo [4, 3, 2-pq] [2, 6] benzodioxa cyclooctadecin-13, 2- [2H] pyran] , milbemycin B deriv.; (+)-Milbemycin α1; Antibiotic B 41A3; Emamectin A3; GWN 1725; Gowan 1725; Koromite; Matsuguard; Mesa; Mesa (acaricide); Milbeknock; Milbemectin; Milbemycin A3; Milbemycin α1; Ultiflora; Milbemycin EP Impurity B.
