To obtain enough materials and confirm the chemical structures for the new pepticinnamins, we have scaled up the fermentation of the mutant S. mirabilis P8-A2 (azdB STOP ) through a 5 L solid fermentation using soya flour mannitol (SFM) agar plates for 10 days to yield a 7.2 g of EtOAc crude extract, which was subjected to a flash column chromatography on C-18 silica gel, and Sephadex LH-20 followed by further purification using preparative HPLC, yielding compounds 1 (5 mg), 2 (2 mg), 3 (2.5 mg) and 4 (3 mg) which were studied by NMR (Tables and), MS, and Marfey´s reaction.
