Phenobarbital derivatives synthesized out of the alkyl chain at the 5-position, particularly with hydrophilic properties, and carrying an active ester at the end, allow formation of aminodextran conjugates that give curves in the desired range of the assay in the ONLINE TDM microparticle assay format when matched against the Roche FPIA antibody specific for phenobarbital (“an antibody specific for phenobarbital”).
Complexes of the [Co(tripeptidato)(NH3)2] and NH4[Co(tetrapeptidato)(NH3)2] types (tripeptidato and tetrapeptidato denote the tri- and tetraanions of the coordinating peptides respectively) have been prepared and characterized by means of their electronic, 1H NMR, and circular dichroism (CD) spectral data. In the NH4[Co(tetrapeptidato) (NH3)2] complex, the pep tide coordinates to cobalt(III) as a quadridentate

Synthesis of Orthogonally Protected Bis(aminomethyl)malonic Acid, and Its Use as a Key Building Block in the Preparation of Cyclic Peptide Conjugates of 2-N-Alkyl-1,2,3,4-tetrahydroisoquinoline on a Solid Support
Orthogonally protected bis(aminomethyl)malonicacid (1) was synthesized and used as a key building block for the construction of cyclic peptide conjugates on a solid support. The applicability of the building block was demonstrated by preparation of 19 backbone cyclized/branched peptide conjugates of N-2-alkyl-5-(3-aminopropoxy)-1,2,3,4-tetrahydroisoquinoline as stereoisomeric pairs.
