TLDR Calancardin B may help reduce inflammation in immune cells.
This study investigated the immunomodulatory potential of compounds isolated from the methanol extract of *Calanthe cardioglossa*. Researchers identified one new dihydrophenanthrene derivative and two new bibenzyl-dihydrophenanthrene derivatives, along with 12 known compounds. The study focused on their effects on THP-1 monocytes and human peripheral blood mononuclear cells (PBMCs) from multiple sclerosis patients. Five compounds notably reduced TNF-α levels in LPS-stimulated THP-1 monocytes, with calancardin B showing significant TNF-α reduction in both THP-1 monocytes and CD14<sup>+</sup> monocytes from MS PBMCs, highlighting its potential as an immunomodulatory agent.
