  The new structural classes of ultrashort peptides that exhibit potent microbicidal action have potential as future drugs. Herein, we report that C-2 arylated histidines containing tripeptides His(2-Ar)-Trp-His(2-Ar) exhibit potent antifungal activity against Cryptococcus neoformans with high selectivity. The most potent peptide 12f [His(2-biphenyl)-Trp-His(2-biphenyl)] displayed high in vitro activity against C. neoformans (IC50 = 0.35 mu g/mL, MIC = MFC = 0.63 mu g/mL) with a selectivity index of >28 and 2 times higher potency compared to amphotericin B. Peptide 12f exhibited proteolytic stability, with no apparent hemolytic activity. The mechanism of action study of 12f by confocal laser scanning microscopy and electron microscopy indicates nuclear fragmentation and membrane disruption of C. neoformans cells. Combinations of 12f with fluconazole and amphotericin B at subinhibitory concentration were synergistic against C. neoformans. This study suggests that 12f is a new structural class of amphiphilic peptide with rapid fungicidal activity caused by C. neoformans.

  Rapid increase in the emergence of resistance against existing antifungal drugs created a need to discover new structural classes of antifungal agents. In this study we describe the synthesis of a new structural class of short antifungal peptidomimetcis, their activity, and plausible mechanism of action. The results of the study show that peptides lie and Ware more potent than the control drug amphotericin B, with no cytotoxicity to human cancer cells and noncancerous mammalian kidney cells. The selectivity of peptides to fungus is depicted by transmission electron microscopy studies, and it revealed that lie possibly disrupts the model membrane of the fungal pathogen.
• Regiospecific Direct C-H Arylation at the 2-Position of l-Histidine Using Arylboronic Acids
  作者：Rahul Jain、Amit Mahindra

  DOI：10.1055/s-0031-1290381

  日期：2012.7

  The first regiospecific direct C-2 arylation procedure for histidine using arylboronic acids has been developed. The reaction allows a one-step synthesis of a large variety of 2-aryl-L-histidines using ammonium persulfate and catalytic silver nitrate in TFA and CH2Cl2/H2O (1:1) at ambient temperature.
