Highly Diastereoselective Access to Densely Functionalized Piperidine Cores of Influenza Endonuclease Inhibitors via a Metal-Free S1 Approach.

A novel, highly diastereoselective, and metal-free synthesis of multisubstituted piperidines via an S1 approach is reported in this study. The method allows for the preparation of highly functionalized compounds with exceptional diastereomeric selectivities and consistently reproducible yields. These compounds are of significant interest due to their remarkable biological activities toward influenza endonuclease.

A RAPID DIAGNOSTIC PCR ASSAY FOR THE DETECTION OF SCHISTOSOMA MANSONI IN THEIR SNAIL VECTORS.

Accurate detection of schistosome infections in snails is vital for epidemiologic and laboratory studies. Traditional microscopy methods to detect schistosomes in snails are hindered by long prepatent periods and snail survivorship, leading to inaccurate assessment of infections. A rapid, multiplexed PCR assay targeting Biomphalaria sudanica or Biomphalaria glabrata (internal control) and Schistosoma mansoni DNA is described.

Definition of sinonasal and otological exacerbation in patients with primary ciliary dyskinesia: an expert consensus.

Background: Recurrent infections of the nose, sinuses and ears are common problems for people with primary ciliary dyskinesia. While pulmonary exacerbations in primary ciliary dyskinesia are defined, there is no definition for ear-nose-throat exacerbations, a potential outcome for research and clinical trials.

Methods: We set up an expert panel of 24 ear-nose-throat specialists, respiratory physicians, other healthcare professionals and patients to develop consensus definitions of sinonasal and otological exacerbations in children and adults with primary ciliary dyskinesia for research settings.

Metabolic glycan labelling with bio-orthogonal targeting and its potential in drug delivery.

New modes of targeted drug delivery are emerging with promise of enhancing therapeutic efficacy while reducing side effects. This review examines the landscape of metabolic glycan labelling-a technique gaining traction for its potential in specific drug targeting. By exploiting the natural glycan synthetic pathway of monosaccharides, unnatural sugar analogues are incorporated into glycoproteins, allowing for the presentation of unique functional groups on cells.
