3-O-p-Coumaroylquinic acid, hydroxycinnamic acid derivative, is isolated from a 70% methanolic Crataegus extract (Crataegi folium cum flore).

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.

TASP 0277308 is a potent and selective sphingosine 1-phosphate 1 (S1P1) receptor antagonist (IC50 = 7.8 nM). TASP 0277308 inhibits S1P-induced chemotaxis (IC50 = 1.1-1.6 nM), HUVEC cell proliferation (IC50 = 3-3.6 nM) and suppresses angiogenesisin vivo.
