  Synthesis and Antitumor Activity of Ester-Modified Analogues of Bengamide B

  摘要：

  Bengamide B, a novel sponge-derived marine natural product with broad spectrum antitumor activity, was not suitable for further preclinical development because of its difficult synthesis and very poor water solubility. Bengamide B produced a 31% T/C at its solubility-limited maximum intravenous dose of 33 micromol/kg in MDA-MB-435 breast carcinoma implanted subcutaneously as a xenograft in nude mice. Compound 8a, a bengamide B analogue with three structural changes (t-Bu alkene substituent, unsubstituted lactam nitrogen, and inverted lactam 5'-myristoyloxy group), was as potent as bengamide B in vitro and more efficacious than bengamide B in vivo. A series of ester-modified analogues based on 8a were synthesized and tested in vitro and in vivo (MDA-MB-435). The cyclohexyl- and phenethyl-substituted esters, 8c and 8g, respectively, had in vitro and in vivo activities similar to that of 8a and enhanced water solubility (ca. 1 mg/mL). Consequently, 8c and 8g were tested in the MDA-MB-435 xenograft model at 100 micromol/kg and produced 29% and 57% tumor regression, respectively.

  LAF389 的一种方便合成，一种苯甲酰胺 B 类似物

  摘要：

  描述了 LAF389 (9) 的优化、收敛、安全合成，这是一种类似于苯甲酰胺 B 的抗癌剂。从α-d-葡庚糖（d-甘油-d-古洛庚酸）γ-内酯（10）开始，分五步构建内酯15。在醛前体 14 的制备和随后的烯烃化以通过改进的 Julia 方案产生 15 方面进行了重大改进。通过使用 TMSCl 作为添加剂，这种烯烃化得到了显着改善。药物物质的第二个片段，ε-己内酰胺 7，是从 (5R)-5-羟基-l-赖氨酸 (1) 中通过两次一锅法获得的。最后，使用 2-乙基己酸钠 (Na-EH) 用 7 打开 15，得到 8，其脱保护得到 LAF389。

  pocket, seven bengamide derivatives were synthesized and evaluated for inhibition of MtMetAP1a and MtMetAP1c in different metalloforms, inhibition of M. tuberculosis growth in replicating and non‐replicating states, and inhibition of human K562 cell growth. Potent inhibition of MtMetAP1a and MtMetAP1c and modest growth inhibition of M. tuberculosis were observed for some of these derivatives. Crystal structures

  甲硫氨酸氨肽酶 (MetAP) 在许多细菌中执行蛋白质 N 末端加工的基本功能，是开发新型抗结核药物的有希望的目标。天然苯甲酰胺通过靶向 MetAP 酶有效抑制哺乳动物细胞的增殖，与苯甲酰胺衍生物复合的人类 2 型 MetAP 的 X 射线晶体结构揭示了活性位点的关键相互作用。通过保留与结合袋内保守残基的相互作用，同时探索结合袋周围细菌和人类 MetAP 之间的差异，合成了七种苯甲酰胺衍生物，并评估了对不同金属型中Mt MetAP1a 和Mt MetAP1c 的抑制作用，以及对结核分枝杆菌的抑制复制和非复制状态下的生长，以及抑制人类 K562 细胞的生长。对于这些衍生物中的一些，观察到Mt MetAP1a 和Mt MetAP1c 的有效抑制和结核分枝杆菌的适度生长抑制。Mt MetAP1c 与两种衍生物复合的晶体结构为改进这些抑制剂的效力和选择性提供了有价值的结构信息。

  indicated that the 2′R analogues were generally more cytotoxic than the 2′S analogues. Additionally, several analogues exhibited selective inhibition against various cancer cell lines: compounds 32a and 32b selectively inhibited MCF-7 cells, while 33b and 35b were more sensitive toward Lu-1 and HepG-2, respectively. Notably, some of the synthetic analogues possess cytotoxic activities with IC50 values less

  A modular, eight-step synthesis of bengamide E and six analogues from a common chiral pool has been developed. The key step in this approach is a cross-metathesis coupling of various commercial terminal olefins and a common alkene bearing the required stereogenic centers of bengamides lateral chain, which was easily derived from α-D-glucoheptonic-γ-lactone. Complete E-selectivity, and up to 92% yield
