Citrusin B exhibits moderate in vitro inhibitory effect on tobacco mosaic virus replication with IC50 values 0.26?mmol?L?1.

Antennapedia Peptide TFA is a 16 amino acid peptide (RQIKIWFQNRRMKWKK). The DNA binding domain of the Drosophila transcription factor (Antennapedia), a 60 amino acid protein, is rapidly taken up by cells and has been fused to selected antigens to enhance their immunogenicity. A 16 amino acid peptide Antennapedia Peptide TFA from Antennapedia can facilitate the cytoplasmic uptake of cytotoxic T lymphocyte epitope 9-mer peptides.

RGD peptide (GRGDNP) (TFA) promote apoptosis through activation of conformation changes that enhance pro-caspase-3 activation and autoprocessing.
