摘要

Abstract: Full details of concise, diastereocontrolled syntheses of 2-5 and their incorporation into tri-, tetra-, and pentapeptide S, the C-terminus of bleomycin A2, are described. The extension of the studies to the synthesis of a complete set of tri-and tetrapeptide S structural analogs 29a, b and 43b-j is detailed, and their DNA binding constants (apparent KB, calf thymus DNA) and apparent binding site sizes were determined. Consistent with past ...
