Design, synthesis and evaluations of acridone derivatives using Candida albicans—Search for MDR modulators led to the identification of an anti-candidiasis agent
摘要:
In order to search for MDR modulators, rationally designed acridone derivatives were investigated for their effect on influx or efflux of Rhodamine6G (R6G) in CAI4 cells. Results of these investigations indicate that in presence of compound 12, inhibition of growth of CAI4 cells and also an increased influx/efflux of R6G in CAI4 cells have been observed. This seems to be occurring due to the cell wall rupturing of Candida albicans. Compound 12 may be a suitable candidate for candidiasis therapy. (C) 2009 Elsevier Ltd. All rights reserved.
To search multi drug resistance modulators, acridones carrying hydroxyl amine substituent at N-10 and COOH/Cl at C-4 were investigated for their interactions with the three components of efflux pump viz. P-gp, ATP, and Mg2+. Experimental and theoretical results indicated that the compounds with COOH group at C-4 interact with P-gp and Mg2+ while other set of compounds with Cl at C-4 interact with ATP and Mg2+. Spot assay and R6G influx/efflux assay of compound 3 using Candida albicans showed decrease in the fungal growth and efflux of R6G, respectively, in presence of compound 3 suggesting the suitability of this compound for MDR modulation.
