  Unprecedented Biomimetic Homodimerization of Oroidin and Clathrodin Marine Metabolites in the Presence of HMPA or Phosphonate Salt Tweezers

  摘要：

  The first biomimetic homodimerization of oroidin and clathrodin was effected in the presence HMPA and diphosphonate salts, strong guanidinium and amide chelating agents. The intermolecular associations probably interfere with the entropically and kinetically favored intramolecular cyclizations. Use of oroidin.1/2HCl salt or clathrodin.1/2HCl was indicative in the presence of the ambident nucleophilic and electrophilic tautomers of the 2-aminoimidazolic oroidin and clathrodin precursors. Surprisingly, the homodimerization of oroidin led to the nagelamide D skeleton, while the homodimerization of clathrodin gave the benzene para-symmetrical structure 19. The common process was rationalized from tautomeric precursors I and III.

  fungal strain (Candida albicans), and oroidin was found to possess promising Gram-positive antibacterial activity. Using oroidin as a scaffold, 34 new analogues were designed, prepared and screened for their antimicrobial properties. Of these compounds, 12 exhibited >80% inhibition of the growth of at least one microorganism at a concentration of 50 µM. The most active derivative was found to be 4-phenyl-2-aminoimidazole

  海洋生物产生的次级代谢物可能对开发新的药物先导物很有价值，也可以为设计和合成新的生物活性化合物提供结构支架。海洋生物碱、clathrodin 和 oroidin 最初是从 Agelas 属的海绵中分离出来的，它们被制备并评估了它们对三种细菌菌株（粪肠球菌、金黄色葡萄球菌和大肠杆菌）和一种真菌菌株（白色念珠菌）的抗菌活性，并且发现 oroidin 具有有希望的革兰氏阳性抗菌活性。使用 oroidin 作为支架，设计、制备了 34 种新类似物并筛选了它们的抗菌特性。在这些化合物中，12 种在 50 µM 的浓度下表现出对至少一种微生物生长的抑制 > 80%。发现活性最强的衍生物是 4-苯基-2-氨基咪唑 6 小时，其对革兰氏阳性菌的 MIC₉₀（最低抑制浓度）值为 12.5 µM，对大肠杆菌为 50 µM。发现金黄色葡萄球菌和哺乳动物细胞之间的选择性指数对于化合物 6h 为 2.9，这在评估化合物作为抗菌先导物的潜力时很重要。

  [reaction: see text] A short synthesis of the C(11)N(5) oroidin derivatives is reported. The key step of the strategy is a one-pot oxidative bromine-mediated addition of protected guanidines to the N-acyl-1,2-dihydropyridines 9a-c. The new N-acyl-1,2-dihydropyridines were prepared directly from pyridine and pyrrole-2-carbonyl chloride by reduction with borohydride reagent in one step.

  日期：1998.2.1

  The preparation and transformation of 2-amino-4,5-dialkoxy-4,5-dihydroimidazolines A from 2-aminoimidazoles (AIs) is described. The oxidation of 2-aminoimidazole 8 with NCS in methanol affords cyclic guanidine adduct 9 which, upon heating, affords vinylogous AI derivative 3 and 8-aminoimidazolinone (glycocyamidine) 13. Olefin 3 comprises the core structure found in the oroidin alkaloids. Furthermore, oxidation of 8 with B-2 and DMSO affords directly alpha,beta-unsaturated imidazolinone 14 which is the key structural unit comprising the dispacamides (2). A highly facile and practical synthesis of the C11N5 marine sponge alkaloids oroidin (la), clathrodin (1c), and dispacamides (2) is outlined.
