Remisporine B
Application Notes
Remisporine B is a metabolite of a marine fungus Remispora maritima. Remisporine B is a unique cyclopentachromone dimer resulting from a spontaneous Diels-Alder reaction of remisporine A, reported by resaerchers at Wyeth Research in 2003. Remisporine B is a weak antitumor active with IC50 of 83.1 μg/mL for K562 and 75.3 μg/mL for HL-60 tumor cell lines.
