Pokeweed antiviral protein (PAP) is a ribosome-inactivating protein (RIP), which enzymatically removes a single adenine base from a conserved, surface exposed loop sequence of ribosomal rRNA. We now present unprecedented experimental evidence that PA

Polyhydroxylated stilbene analogs of piceatannol are shown to possess protein‐tyrosine kinase (PTK) inhibitory activity. We have developed a novel approach to introduce an amide moiety into the structure of piceatannol. The amido substituted stilbe

The 2-(benzo[d]thiazole-2'-yl)-N-alkylanilines have previously revealed the presence of a strong intramolecular hydrogen bond. This in turn gives rise to a more complicated multiplet for the protons attached to the carbon adjacent to the amino group.
