  Total synthesis and structure assignment of the antitumor antibiotic aranorosin

  摘要：

  The structurally unique antifungal and antitumor antibiotic aranorosin was prepared in a convergent, stereoselective sequence. Oxidative cyclization of N-protected L-tyrosine, followed by face-selective 1,2-addition of [(benzyloxy)methyl]lithium, Henbest oxidation in the presence of Kishi's radical inhibitor, and simultaneous N,O-deprotection led to an amino diol which was N-acylated with the fatty acid side-chain segment. After a low-temperature reduction of the lactone moiety to the lactol, the carbonyl function was regenerated under neutral conditions by diol cleavage with sodium periodate. Preparation of the acid side chain involved a diastereoselective imide alpha-alkylation directed by Evans' oxazolidinone auxiliary, followed by a series of Wittig-Horner chain extensions. Since the relative configuration at the C (6') position of the natural product had not been determined, we prepared both the (6'S) and the (6'R) isomers of aranorosin. Comparison of synthetic material with the reported spectral data for natural (-)-aranorosin, especially H-1 and C-13 NMR and [alpha]D, did not allow a definitive assignment. After purification of a sample of the isolated material from Pseudoarachniotus roseus, the corrected [alpha]D strongly indicated the (6'R)-stereochemistry for the natural compound. This assignment was confirmed by circular dichroism spectra for (6'S)- and (6'R)-aranorosin and the natural material.

  Fatty acid synthase (FAS) catalyzes the synthesis of palmitate from the sequential condensation of an acetyl primer with two carbon units added from malonyl-CoA. Inhibition of the beta-ketoacyl synthase domain of mammalian FAS leads to selective cytotoxicity to various cancer cell lines in vitro and in vivo. Also, inhibitors of FAS can cause reduced food intake and body weight in mice. Naturally occurring

  and for post‐exposure treatment is a continued challenge. In this study, we analyzed the reactivation potency of 111 novel nucleophilic oximes mostly synthesized using the CuAAC triazole ligation between alkyne and azide building blocks. We identified several oximes with significantly improved in vitro reactivating potential for tabun‐inhibited human AChE, and in vivo antidotal efficacies in tabun‐exposed

  乙酰胆碱酯酶（AChE）是一种降解神经递质乙酰胆碱的酶，当被有机磷化合物（OPs）（例如神经毒剂和杀虫剂）共价抑制时，可以被肟重新激活。然而，由于标准吡啶鎓醛肟肟解毒剂的低活化作用，塔邦仍然是最危险的神经制剂之一。因此，寻找最佳的活化剂来预防塔宾毒性和进行暴露后治疗仍然是一个挑战。在这项研究中，我们分析了炔烃和叠氮化物结构单元之间主要通过CuAAC三唑连接而合成的111种新型亲核肟的活化潜能。我们鉴定了几种肟，它们在禁忌暴露的人AChE中具有显着提高的体外再激活潜力，并且在禁忌暴露的小鼠中具有体内解毒作用。
