Synthesis and structure-activity relationship of novel bisindole amidines active against MDR Gram-positive and Gram-negative bacteria
摘要:
A series of novel diamidines with N-substituents on an amidine N-atom were synthesized and evaluated for their cytotoxicity and in vitro antibacterial activity against a range of Gram-positive and Gram-negative bacterial strains. Based on structure-activity relationship, N-substituents with a branched chain and a shorter carbon chain on the amidine N-atom exhibited more promising activity against Gram-negative and MDR-Gram-positive bacteria: compounds 5c and Si were the most powerful candidate compounds. Compound 5c showed greater efficacy than levofloxacin against most drug resistant Gram-positive bacteria and exhibited broad-spectrum antibacterial activity against Gram-negative bacteria, with MIC values in the range of 2-16 mu g/mL. Slightly more potent antibacterial activity against Klebsiella pneumoniae, Acinetobacter calcoaceticus, Enterobacter cloacae, and Proteus mirabilis was observed for 5i in comparison with 5c. Compound 5i also showed remarkable antibacterial activity against NDM-1-producing Gram-negative bacteria, with MIC values in the range of 2-4 mu g/mL, and was superior to the reference drugs meropenem and levofloxacin. Effective antibacterial activity of 5i was also shown in vivo in a mouse model of Staphylococcus aureus MRSA strain, with an ED(50)values of 2.62 mg/kg. (C) 2018 Published by Elsevier Masson SAS.
Palladium-catalyzed benzylation of N-Boc indole boronic acids
摘要:
The direct benzylation of indole 2-boronic acid can be efficiently achieved using trans-PdBr-(N-Succ)(PPh(3))(2), alleviating the need for strong bases or toxic organotin reagents. Under these reaction conditions substituted indole-2-boronic acids and substituted benzyl bromides are cross-coupled to afford aryl(indolo)methanes in good yield. (C) 2010 Elsevier Ltd.

conditions, trapped by a variety of nucleophilic reagents, and used to access a number of novel substituted indoles. Nucleophilicaddition reactions to indolynes proceed with varying degrees of regioselectivity; distortion energies control regioselectivity and provide a simple model to predict the regioselectivity in the nucleophilicadditions to indolynes and other unsymmetrical arynes.

These compounds are shown to bind in the DNA minor groove with high affinity, and exhibit superior in vitro antitrypanosomal activity to that of DAPI. Six new diamidines (5b, 5c, 5d, 5e, 5f and 5j) exhibit superior in vivo activity to that of DAPI and four
