Lasalocid Acid Antibiotic at a Membrane Surface Probed by Sum Frequency Generation Spectroscopy.

Langmuir, 2020
Carboxyl polyether ionophores (CPIs) are widely used as veterinary antibiotics and to increase food-utilization in ruminating animals. Furthermore, CPIs can target drug-resistant bacteria but detailed knowledge about their mode-of-action is needed in ...

Accidental poisoning of 17 dogs with lasalocid

Veterinary Record, 2004
Over a period of 10 days, 17 dogs became weak and developed neurological deficits of different degrees of severity. About 12 hours before these clinical signs appeared they had all eaten a particular brand of commercial dog food from a recently opened bag. They were all quadriparetic and hyporeflexic, and some of them also showed additional systemic or

Barbatimão bark as an alternative to sodium lasalocid in finishing diets for lambs: Carcass characteristics and meat quality.

Meat Science
This study aimed to evaluate the effects of replacing sodium lasalocid with additives from barbatimão bark (Stryphnodendron rotundifolium) on the carcass characteristics and meat quality of feedlot lambs fed a high-concentrate diet.

A rapid and convenient screening method for detection of restricted monensin, decoquinate, and lasalocid in animal feed by applying SERS and chemometrics.

Food and Chemical Toxicology, 2020
The surface-enhanced activities of size- and shape-controlled gold nanoparticles (AuNPs) with superior chemical stability were investigated to explore a possible development of a simple and non-destructive spectroscopic method to help the regulatory ...

Solution conformation of lasalocid and lasalocid-Na+ (X-537A)

Bioorganic Chemistry, 1976
Abstract The complete unraveling of the proton nuclear magnetic resonance spectra at high field strength of Lasalocid ( 1 ) and its sodium salt ( 2 ) in different solvents allowed the definition of their solution conformations. The free acid, a lozengeshaped molecule of 17 × 13 × 9 A is prefolded in a way almost identical to that of its sodium ...

Spectrofluorometric Determination of the Antibiotic Lasalocid in Blood

Journal of Pharmaceutical Sciences, 1975
A spectrofluorometric assay was developed for the determination of the antibiotic lasalocid in dog blood, based on the intrinsic fluorescence of the compound in ethyl acetate. The assay can measure "total" levels of drug and any metabolites present. The specificity of the assay was verified by TLC separation of the dog blood extract, which indicated ...

In vitro evaluation of natural plant additives as substitutes for sodium lasalocid on the rumen short-chain fatty acid profile

New Zealand Journal of Agricultural Research
The objective of this study was to evaluate the effects of replacing sodium lasalocid (LAS) with different doses of copaiba oleoresin (CO) and dried barbatimão bark (DBB) on the rumen short-chain fatty acid profile in an in vitro ruminal fermentation ...

Lasalocid A selectively induces the degradation of MYD88 in lymphomas harboring the MYD88 L265P mutation.

Blood
Myeloid differentiation primary response protein 88 (MYD88) is a key adaptor molecule in the signaling pathways of toll-like receptor (TLR) and interleukin-1 receptor (IL-1R). A somatic mutation resulting in a leucine-to-proline change at position 265 of
