Background:

Brazilein is a phytochemical that has been found inC. sappanand has diverse biological activities.^1,2,3,4It is active againstE. coli,P. aeruginosa, and methicillin-susceptibleS. aureus(MSSA; MICs = 32, 512, and 512 µg/ml), as well as a panel of 10 clinical isolates of methicillin-resistantS. aureus(MRSA; MIC₅₀s = 16-32 µg/ml).¹Brazilein (10 µM) inhibits LPS-induced nitric oxide (NO) production in J774A.1 cells.²It is cytotoxic to HepG2, Hep3B, MDA-MB-231, MCF-7, A549, and Ca9-22 cancer cells (IC₅₀s = 3.15, 3.42, 2.36, 3.96, 9.68, and 8.63 µg/ml, respectively).³Brazilein (1-10 µg/ml) also inhibits the proliferation of isolated mouse spleen lymphocytes induced by concanavalin A .⁴
