AI Article Synopsis

  • The structure of globomycin, a new cyclic peptide antibiotic, was established using mass, PMR, and CMR spectra along with chemical degradation methods.
  • It is composed of several amino acids: L-serine, L-allo-threonine, glycine, N-methylleucine, L-allo-isoleucine, and 3-hydroxy-2-methylnonaic acid.
  • Notably, L-allo-threonine, L-allo-isoleucine, and 3-hydroxy-2-methylnonaic acid are unique components sourced from natural products, and a new mass analysis technique was developed for analyzing diastereoisomers of allo-th

Article Abstract

The structure of globomycin has been determined by mass, PMR and CMR spectra and by chemical degradation. Globomycin is a new cyclic peptide antibiotic composed of L-serine, L-allo-threonine, glycine, N-methylleucine, L-allo-isoleucine and 3-hydroxy-2-methylnonaic acid. Among these components, L-allo-threonine, L-allo-isoleucine and 3-hydroxy-2-methylnonaic acid are novel components from natural products. A newly developed mass analysis has been introduced for determining the diastereoisomers of allo-threonine.

Background: Host commensal gut microbes are shown to be crucial for microglial maturation, and functions that involve innate immune responses to maintain brain homeostasis. Sex has a crucial role in the incidence of neurological diseases with females showing higher progression of AD compared with males. Transcriptomics has been a powerful tool for the characterization of microglial phenotypes however, there is a large gap in relating to their functional protein abundances.

Background: Cardiovascular disease causes vascular dementia and contributes to most clinical dementia. This is embodied in the concept of vascular contributions to cognitive impairment and dementia (VCID). The potent endogenous peptide endothelin-1 (ET1) causes small artery vasoconstriction and fibrosis.

Background: A drug cocktail targeting different processes of aging was tested in an aging mouse model of Alzheimer's disease (AD) neuropathologic change as an intervention to improve behaviors corresponding to cognitive dysfunction in AD.

Method: A cocktail of acarbose/rapamycin/phenylbutyrate or a control treatment was administered (medicated vs. non-medicated chow) chronically to 22 months-old mice that received viral vector injections to induce amyloid and tau pathology in the hippocampus at 24 months of age.
