TLDR Calancardin B may help reduce inflammation in immune cells.
The study explores the immunomodulatory effects of compounds from the orchid *Calanthe cardioglossa*, particularly focusing on calancardin B, a bibenzyl-dihydrophenanthrene derivative. Calancardin B was found to significantly reduce LPS-induced TNF-α production in THP-1 monocytes and PBMCs from five multiple sclerosis (MS) patients, especially in CD14+ monocytes, which are key contributors to neuroinflammation in MS. The findings suggest that calancardin B, due to its specific methoxy and hydroxy groups, holds therapeutic potential in modulating immune responses and could be a promising strategy for treating MS by targeting monocyte activity.
