The synthesis and antitumor activity of a novel didemnin B analogue containing a Psi [CH2NH] amide bond surrogate between N-Me-D-Leu(7) and pro(8) are reported. The analogue shows activity (GI(50) = 4 nM) comparable to that of didemnin B (GI(50) = 13 nM) in the NCI-60 tumor cell screen. This result, along with new data from previously reported synthetic didemnin analogues, is discussed within the context of the side-chain SAR for didemnins. (C) 2001 Elsevier Science Ltd.
