| 21-hydroxyoligomycin A (Nemadectin omega, Antibiotic LL-F28249 omega) | 21-Hydroxyoligomycin A is a rare member of the oligomycin class isolated as a co-metabolite of nemadectin, hence its original naming as nemadectin omega. Only limited literature references to this metabolite are available.

| 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.

| Moxidectin | Moxidectin is a semi-synthetic milbemycin derived from nemadectin by selective oxidation followed by methyloximation. Moxidectin was patented in 1991 as an anthelmintic for internal parasite control. The presence of the methyloxime affords moxidectin a greater hydrophobicity and longer biological half-life compared to nemadectin. It binds selectively to parasite. Group: Biochemicals. Grades: Highly Purified. CAS No. 113507-06-5. Pack Sizes: 5mg. US Biological Life Sciences. | Worldwide |
