natural product currently under phase II clinical trials. Here, we report the solid phase synthesis of 132 novel analogues of kahalalide F and their in vitro activity on a panel of up to 14 cancer cell lines. The structure-activity relationship of these analogues revealed that KF is highly sensitive to backbone stereotopical modification but not to side chain size modification. These observations suggest

The solid-phasesynthesis of six novel analogues of Kahalalide F (KF), a natural product currently undergoing Phase II clinical trials, is reported. In all these compounds, amides were used as isosteres for the depsi bond. For two of these compounds, we performed an efficient synthesis of N-Fmoc-protected (2R,3R)-2-amino-3-azidobutanoic acid, precursor of the aza-threonine. This is the first example
据报道,目前正在进行 II 期临床试验的天然产物 Kahalalide F (KF) 的六种新型类似物的固相合成。在所有这些化合物中,酰胺被用作 depsi 键的等排体。对于这些化合物中的两种,我们进行了 N-Fmoc 保护的 (2R,3R)-2-amino-3-azidobutanoic 酸(氮杂苏氨酸的前体)的有效合成。这是在固相中制备含氮杂-苏氨酸的肽中叠氮基团的固相还原的第一个例子。
