A review on the effect of macrocyclic lactones on dung-dwelling insects: Toxicity of macrocyclic lactones to dung beetles

Onderstepoort J Vet Res, 2015
Avermectins and milbemycins are commonly used in agro-ecosystems for the control of parasites in domestic livestock. As integral members of agro-ecosystems with importance in maintaining pasture health through dung burial behaviour, dung beetles are an excellent nontarget bio-indicator taxon for examining potential detrimental effects of pesticide ...

FIVE REASONS TO PRESCRIBE A MACROLIDE FOR ENT DISEASE

Медицинский совет, 2016
Macrolides are antibiotics the chemical structure of which has a macrocyclic lactone ring. Macrolides have several advantages over other groups of antibiotics. They are characterized by high antibacterial activity against intracellular pathogens and have

Dog Waste Creates a Preference‐Performance Mismatch for Urban Dung Beetles

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study demonstrates a preference‐performance mismatch associated with an abundant urban resource. The dung beetle Onthophagus orpheus strongly prefers domestic dog dung despite substantially lower offspring survival, suggesting that the accumulation of pet waste in urban environments may have unintended ecological consequences for dung beetle ...

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...

Perspectives on the utility of moxidectin for the control of parasitic nematodes in the face of developing anthelmintic resistance

International Journal for Parasitology: Drugs and Drug Resistance, 2019
Macrocyclic lactone (ML) anthelmintics are the most important class of anthelmintics because of our high dependence on them for the control of nematode parasites and some ectoparasites in livestock, companion animals and in humans. However, resistance to

Structural diversity and biological activities of naturally derived bafilomycins from actinomycetes

Beni-Suef University Journal of Basic and Applied Sciences
Background Bafilomycins (Baf) are plecomacrolide antibiotics characterized by a 16-membered macrocyclic lactone containing two sets of conjugated dienes linked by a 1,3-dimethyl propan-2-ol (C3) spacer to an unusually folded tetrahydropyran ring.

Laboratory and field studies to investigate the efficacy of a novel, orally administered combination product containing moxidectin, sarolaner and pyrantel for the prevention of heartworm disease (Dirofilaria immitis) in dogs

Parasites & Vectors, 2019
Background Dirofilaria immitis is a filarial parasite of dogs that can cause serious or fatal cardiopulmonary disease. Three studies were conducted to evaluate the efficacy and safety of monthly treatment with moxidectin in a chewable tablet product in ...

SMART-Guided Isolation and Identification of Seven-Membered Cembranolides with Anti-Inflammation Activity from the Soft Coral Sinularia mollis

Marine Drugs
The first systematic chemical investigation on Sinularia mollis resulted in the isolation and identification of 36 seven-membered cembranolides, including 14 new compounds named sinumollolides A–N (1–14) and 22 known analogs (15–36) by HSQC-based small ...
