[Uses]

Milbemycins are a complex family of macrocyclic lactones containing a highly characteristic spiroketal group, produced by Streptomyces hydroscopicus subsp. aureolarcrimosus. Milbemycin D is a minor member of a group of analogues containing a 25-isopropyl substituent. Milbemycin D is a highly selective and potent nematocide and insecticide. Like the closely related avermectin, milbemycins are thought to act by opening glutamate sensitive chloride channels.

Milbemycin D is a minor member of a group of analogues containing a 25-isopropyl substituent. Milbemycin D is a highly selective and potent nematocide and insecticide. Like the closely related avermectin, milbemycins are thought to act on chloride-gated ion channels.
[Definition]

ChEBI: Milbemycin D is a milbemycin originally isolated from Streptomyces hygroscopicus with formula C33H48O7 that has insecticidal and anthelmintic proerties. It has a role as an insecticide, an anthelminthic drug and a nematicide.
