Antagonist of formyl peptide receptor 1 (FPR1). Reduces superoxide production induced by fMLF with an EC50 of 0.63 μM. Almost completely blocks fMLF-stimulated primary granule exocytosis.

Echimidine, a major hepatotoxic dehydropyrrolizidine alkaloid produced by E. plantagineum, in the honey (780 ng/g) and in the subsequent mead samples (236-540 ng/mL). Echimidine-N-Oxide has antifungal activity.

(Iso)-MS4322 ((Iso)-YS43-22) is a selective and potent protein arginine methyltransferase 5 (PRMT5) degrader with potential anticancer activity that effectively reduces PRMT5 protein levels in MCF-7 cells and inhibits the growth of a wide range of cancer cells.
