Physiological Reports, Volume 14, Issue 11, June 2026.Abstract Heart failure with preserved ejection fraction (HFpEF) is associated with skeletal muscle dysfunction that contributes to exercise intolerance and disease progression. Altered Ca2+ homeostasis and increased oxidative stress have been proposed as mechanisms underlying muscle weakness in HFpEF; however, the effects of aerobic exercise on ...

A New Synthetic Approach to the Preparation of Indolo[3,2‐c]quinolines From Sulfonylalkyl Indoles
Advanced Synthesis &Catalysis, Volume 368, Issue 10, 19 May 2026.Functionalized indolo[3,2‐c]quinolines can be efficiently prepared from sulfonylalkyl indoles by a cascade process involving reduction, vinylogous aza‐Michael and aromatization reactions triggered by zinc powder in acetic acid at reflux. The reductive cyclization of sulfonylalkyl indoles obtained from 2‐(o‐nitroaryl)indoles, provides an efficient ...
