A green pigment, viridaphin A1 glucoside (1), was isolated from the green aphid Megoura crassicauda. One- and two-dimensional NMR spectrometric analyses of 1 and its aglycone established the structure as an octacyclic compound. Viridaphin A1 glucoside exhibited cytotoxicity against HL-60 human tumor cells with an IC50 of 23 μM and antibacterial activity against Bacillus subtilis NBRC 3134 with a minimum inhibitory concentration of 10.0 μg/mL. These results suggested that aphid pigments may protect aphids from invasive species, including viruses and bacteria.

Racemic protein crystallography is an emerging methodology to obtain high-resolution protein structures. Preparation of both a mirror image of protein and a mirror image of glycan is essential to apply the new methodology to glycoprotein. This article describes an efficient synthesis of L-galactose that is amirror image of D-galactose. The developed method takes only 6 steps from D-galactose without any chromatographic purification.
