Anidulafungin side chain intermediate 4''-(pentyloxy)-[1,1':4',1''-terphenyl]-4-carboxylic acid

The invention relates to the preparation method of anidulafungin side chain intermediate 4''-(pentyloxy)-[1,1':4',1''-terphenyl]-4-carboxylic acid. The preparation method includes the steps of S1, subjecting 4 hydroxy-4'-bromobiphenyl and 1-bromopentane to nucleophilic substitution to obtain 4'-bromo-4-n-amyloxybiphenyl; S2, subjecting the 4'-bromo-4-n-amyloxybiphenyl and tetrahydroxydiboron to Suzuki coupling reaction to obtain 4-pentyloxy-4'-biphenylboronic acid; S3, subjecting the 4-pentyloxy-4'-biphenylboronic acid and methyl 4-iodobenzoate to Suzuki coupling reaction to obtain methyl 4''-(pentyloxy)-[1,1',4'-1''-terphenyl]-4-formate; S4, hydrolyzing to obtain 4''-(pentyloxy)-[1,1':4',1''-terphenyl]-4-carboxylic acid. arylboronic acid is prepared through Suzuki coupling; the target product is then prepared through Suzuki coupling and alkali hydrolysis; the preparation method has the advantages of low cost and good process operation simplicity and safety.

Total synthesis and structure-activity relationships of new echinocandin-like antifungal cyclolipohexapeptides

A series of new echinocandin-like cyclolipohexapeptides were designed and total synthesized via solution phase [3 + 3]-segment coupling strategy with an attempt to improve antifungal activity. The designed compounds showed potent antifungal activities with broad spectrum. In particular, 11 compounds (i.e. 28a-e, 28g, 28i-j, 29a, 29c and 29e) showed better in vitro antifungal activities against Candida albicans or Aspergillus fumigatus than caspofungin. Moreover, the synthesized compounds provided new SAR information for the echinocandins. The findings in this work suggested that the "left" tripeptide segment of cyclolipohexapeptide scaffold might be a hydrophilic structural motif, whereas the "right" lipopeptide segment was preferred as a hydrophobic core. The amino acid component of the cyclolipohexapeptide scaffold could significantly affect the SAR of the side chains.
