Synthesis and physiological effects of new 4-aminophenol derivatives as paracetamol analogues.

Paracetamol has antipyretic and analgesic properties and it is widely used for fever and pain. However, paracetamol is partially metabolized to N-acetyl-p-benzoquinoneimine, which in overdose leads to liver necrosis, urging for safer paracetamol analogues. As the latter, new para-aminophenol derivatives containing fragments of acetic acid, saturated fatty acids and monoethanolamine were synthesized.

Migraine and cognitive dysfunction: a narrative review.

The association between migraine and cognitive function has been studied during the last decade, however, this relationship is not well established. As migraine prevalence is highest between the ages of 30-40, aligning with some of our most productive years, we must understand cognitive changes within this disorder. Cognitive impairment potentially limits social and professional interactions, thus negatively impacting quality of life.

Elucidation of cytotoxicity of α-Synuclein fibrils on immune cells.

Progressive aggregation of α-synuclein (α-Syn), a small cytosolic protein involved in cell vesicle trafficking, in the midbrain, hypothalamus, and thalamus is linked to Parkinson's disease (PD). Amyloid oligomers and fibrils formed as a result of such aggregation are highly toxic to neurons. However, it remains unclear whether amyloid-induced toxicity of neurons is the primary mechanism of the progressive neurodegeneration observed upon PD.

Recent advances in asymmetric synthesis cyclopropanol intermediates.

Cyclopropanols have attracted significant attention in organic synthesis as versatile three-carbon synthons, as this readily available class of donor-activated cyclopropanes undergoes miscellaneous transformations, either ring-opening or with retention of the cyclopropane ring. This review summarizes stereoselective and stereoretentive transformations suitable for asymmetric synthesis. The utility of cyclopropanols is discussed for two main strategies: (i) substrate-controlled transformations using enantiomerically enriched cyclopropanol intermediates through a traditional approach, and (ii) the use of nonchiral or racemic cyclopropanols, where asymmetric induction is achieved through a chiral catalyst, representing a direction that has recently emerged.

The Frequency and Incidence of QT Prolongation with Extended Use of Bedaquiline or Delamanid in a Large, Multi-Country MDR/RR-TB Cohort.

Background: The 2022 WHO guidelines on multi-drug/rifampicin resistant tuberculosis (MDR/RR-TB) recommend six months of bedaquiline (Bdq) in the all-oral 9-month shorter regimen and six months or longer for Bdq and delamanid (Dlm) in the 18-20-month longer regimen. However, lack of evidence on extended treatment using Bdq or Dlm has limited their use to six months. We examine the frequency and incidence of QT prolongation based on duration of Bdq and/or Dlm use in longer regimens.
