Isoflavones as potentiators of antibacterial activity

, p. 5677 - 5679 (2003)
Isoflavones isolated from Lupinus argenteus were found to potentiate the antibacterial activity of α-linolenic acid, also found in the same plant. The isoflavones also potentiated the activity of the natural plant antibiotic berberine and the synthetic fluoroquinoline antibiotic norfloxacin. The isoflavones increased the uptake of berberine into Staphylococcus aureus cells, indicating that they may be inhibiting a multidrug resistance pump (MDR). Thus, L. argenteus contains a weak antibacterial and also MDR pump inhibitors, which increase its potency.

Diversity-oriented synthesis of derivatives of natural products is an important approach for the discovery of novel drugs. In this paper, a series of novel 3,4-diaryl-1H-pyrazoles and 3,5-diaryl-1H-pyrazoles derivatives were synthesized through the one-po

A series of deoxybenzoin derivatives from genistein were synthesized and their structures were elucidated by 1H NMR, mass spectral data and micro analyses. The structures of 2, 7 and 10 were determined by single-crystal X-ray analysis. These obtained compounds were evaluated for their assayed antibacterial (Bacillus subtilis, Escherichia coli, Pseudomonas fluorescence and Staphylococcus aureus) and antifungal (Aspergillus niger, Candida albicans and Trichophyton rubrum) activities by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method. Most compounds have displayed comparable antibacterial activity against bacterial. On the basis of the biological results, structure-activity relationships are discussed.
