The methanolic extract of the leaves of Liriodendron tulipifera was found to show inhibitory activity towards farnesyl protein transferase (FPTase). Bioassay-guided fractionation of the methanolic extract resulted in the isolation of lipiferolide, an inhibitor of FPTase. This compound inhibited the FPTase activity in a dose-dependent manner, and showed cell(More)
The methanolic extract of the aerial parts of Centipeda minima was found to show inhibitory activity on farnesyl protein transferase (FPTase). Bioassay-guided fractionation of the methanolic extract resulted in the isolation of 6-O-angeloylprenolin, as an inhibitor on FPTase. This compound inhibited FPTase activity in a dose-dependent manner, and the IC50(More)
To generate a biobetter that has improved therapeutic activity, we constructed scFv libraries via random mutagenesis of several residues of CDR-H3 and -L3 of hu4D5. The scFv clones were isolated from the phage display libraries by stringent panning, and their anti-proliferative activity against HER2-positive cancer cells was evaluated as a primary selection(More)
The methanolic extract of the aerial parts of Persicaria thunbergii was found to show inhibitory activity on Farnesyl Protein Transferase (FPTase). Bioassay-guided fractionation of the methanolic extract resulted in the isolation of isorhamnetin, as an inhibitor on FPTase. This compound inhibited FPTase activity in a dose-dependent manner, and the IC50(More)
