Structure-activity relationship studies performed with various didemnin analogues have demonstrated that the linear side chain portion of the molecule is vital to its biological potency. Three tamandarin analogues were prepared which consisted of the macrocycle of the natural product tamandarin B and side chains found in extremely potent didemnin compounds. The macrocycle was prepared using a revised approach with a new site of macrolactamization. The final analogues will all be subjected to biological activity screening.

520 # $a Structure-activity relationship studies performed with various didemnin analogues have demonstrated that the linear side chain portion of the molecule is vital to its biological potency. Three tamandarin analogues were prepared which consisted of the macrocycle of the natural product tamandarin B and side chains found in extremely potent didemnin compounds.

520 # $a The tamandarins are a class of naturally occurring cyclic depsipeptides isolated from a Brazilian ascidian. They are structurally similar to a more widely studied class of depsipeptides known as the didemnins. Both the didemnins and the tamandarins are of interest because of their wide range of impressive biological activity and their potential use as a drug therapy for many different diseases. Although numerous synthetic studies have identified structural elements that are critical in the biological activity profile, the identification of a receptor protein that could explain the variety of biological properties remains elusive. In an effort to identify a receptor protein, a synthetic analogue, [lys3] tamandarin B, was prepared. This analogue was designed for use in affinity chromatography studies and its synthetic preparation is discussed in detail. As the tamandarins are accepted as synthetic mimics of the didemnins, it is hoped that the future affinity studies conducted with this analogue will identify molecular targets of both the tamandarins and didemnins.
