A convenient synthetic pathway enabling D-glucal and D-galactal pinacol boronates to be prepared in good isolated yields was achieved. Both pinacol boronates were tested in a series of cross-coupling reactions under Suzuki-Miyaura cross-coupling conditions to obtain the corresponding aryl, heteroaryl, and alkenyl derivatives in high isolated yields. This methodology was applied to the formal synthesis of the glucopyranoside moiety of papulacandin D and the first total synthesis of bergenin.

Background: Drug-induced organ toxicity is a significant health concern, with gentamicin known for its effective antibacterial properties but also severe side effects, particularly cytotoxicity in liver and kidney tissues. This current study observed the preventive role of baicalein and bergenin against hepatic and renal injuries caused by gentamicin in rats.
Methods: Thirty-two male Sprague Dawley rats were divided into four groups, namely, control, gentamicin (gentamicin 80 mg/kg/day), baicalein (gentamicin 80 mg/kg/day + baicalein 100 mg/kg/day) and bergenin (gentamicin 80 mg/kg/day + bergenin 100 mg/kg/day).

Neurological disorders refer to the pathological changes of the nervous system involving multiple pathological mechanisms characterized by complex pathogenesis and poor prognosis. Peroxisome proliferator-activated receptor (PPAR) is a ligand-activated transcription factor that is a member of the nuclear receptor superfamily. PPAR has attracted considerable attention in the past decades as one of the potential targets for the treatment of neurological disorders.

Background: Intracerebral hemorrhage (ICH) is a severe form of stroke characterized by high incidence and mortality rates. Currently, there is a significant lack of effective treatments aimed at improving clinical outcomes. Our research team has developed a three-dimensional (3D) biological scaffold that incorporates Bergenin, allowing for the sustained release of the compound.

Bergenin is the main active ingredient of Bergenia purpurascens, a medicinal plant which has long been used to treat a variety of Th17 cell-related diseases in China, such as allergic airway inflammation and colitis. This study aimed to uncover the underlying mechanisms by which bergenin impedes Th17 cell response in view of cellular metabolism. In vitro, bergenin treatment reduced the frequency of Th17 cells generated from naïve CD4 T cells of mice.
