practical protocol for completely regioselective and highly stereoselective synthesis of vinyldiazaphosphonates from N-heterocyclic phosphine (NHP) and allenes via phospha-Michael/intramolecular nucleophilic substitution reaction has been developed. This transformation enabled the synthesis of valuable densely functionalized vinyldiazaphosphonates with a β-, γ-unsaturated ester moiety under mild reaction

A simple and efficient reaction protocol for the synthesis of N-benzylthioureas is described from benzylisothiocyanate (BITC: 94% pure/ GC-MS), isolated from crushed papaya seeds.
Benzyl isothiocyanate (BITC), a dietary isothiocyanate (ITC) derivedfrom cruciferous vegetables, has anticancer properties. It is believed that the ITC moiety (-N═C═S) that reacts predominantly with thiol compounds plays a central role in triggering the activities resulting from these properties. Recent studies have demonstrated that ITCs also covalently modify amino moieties in a protein. In this
The present invention discloses novel biologically produced bifunctional chimeric antibodies, directed against human carcinoembryonic antigen and metal chelates, having two sets of antigen-specific variable regions of defined amino acid sequences. DNA constructs for the light and heavy chain variable regions comprising the novel antibodies of the invention are disclosed. Eukaryotic host cells capable of biological expression of the bifunctional chimeric antibodies and comprising the novel bifunctional chimeric antibody-encoding DNA constructs are also provided.
