Abstract We report NMR studies on a known 22,23-dioxygenated milbemycin which show that the 22 and 23 oxygen atoms are trans diequatorial (I) and not trans diaxial (II) as previously reported1. The stereochemistry of milbemycins α5 to α8 is also discussed in the light of this observation. 
C-13β-ACYLOXYMILBEMYCINS, A NEW FAMILY OF MACROLIDES
TLDR
A family of novel milbemycins possessing C-13β-acyloxy substitution was produced by Streptomyces hygroscopicus ATCC 53718 and possess anthelmintic and ectoparasiticidal activity.
A novel series of milbemycin antibiotics from Streptomyces strain E225. II. Isolation, characterization, structure elucidation and solution conformations.
TLDR
A novel series of milbemycin antibiotics were isolated from the fermentation broth of a Streptomyces species designated E225 and the structures of the four main metabolites were determined by NMR techniques.
Avermectins and Milbemycins
The discovery of the avermectins and milbemycins in the mid nineteen seventies heralded a new era of antiparasitic chemotherapy. However, these compounds not only possess unprecedented activity
Neocitreamicins I and II, Novel Antibiotics with Activity against Methicillin-Resistant Staphylococcus aureus and Vancomycin-Resistant Enterococci
TLDR
Two novel antibiotics, neocitreamicins I and II, were isolated from a fermentation broth of a Nocardia strain and showed in vitro activity against Gram-positive bacteria including strains of methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecalis.
Further New Milbemycin Antibiotics from Streptomyces bingchenggensis
Three new α-class milbemycins from Streptomyces bingchenggensis, named milbemycins α28, α29 and α30, have been isolated and characterized. On the basis of detailed spectroscopic analysis and
