Naphthopyranone Glycosides from Paepalanthus microphyllus
Three new naphthopyranone glycosides, paepalantine-9-O-beta -D-glucopyranosyl-(1 -->6)-beta -D-glucopyranoside (I), paepalantine-9-O-alpha -L-arabinopyranosyl-(1 -->6)-beta -D-glucopyranoside (2), and paepalantinc-9-O-alpha -L-rhamnopyranosyl-( (1 -->6)-beta -D-glucopyranoside (3), along wi...

Summary: | Three new naphthopyranone glycosides, paepalantine-9-O-beta -D-glucopyranosyl-(1 -->6)-beta -D-glucopyranoside (I), paepalantine-9-O-alpha -L-arabinopyranosyl-(1 -->6)-beta -D-glucopyranoside (2), and paepalantinc-9-O-alpha -L-rhamnopyranosyl-( (1 -->6)-beta -D-glucopyranoside (3), along with the known paepalantine-9-O-beta -D-glucopyranoside (4) were isolated from aerial parts of Paepalanthus microphyllus. These compounds were characterized by spectrometric methods, including electrospray mass spectrometry and 1D and 2D NMR experiments. As a part of our program for screening natural compounds for anti-HIV activity, compounds 1-4 were tested in C8166 cells infected with HIV 1(MN). |
