Biological testing Antimicrobial and antiquorum-sensing activities Compounds 4a-e, 5a-c, 6a-r and 7a-d were screened for their antibacterial activity against Escherichia coli, Staphylococcus aureus and Bacillus cereus in Luria-Bertani agar medium [7,8] and antifungal activity against Candida albicans in Sabouraud's agar medium, Aspergillus fumigatus 293 in glucose minimal medium [8,9]. In addition, their antipathogenic potential was checked by examining the antiquorum-sensing activity against Chromobacterium violaceum ATCC 12472 in Luria-Bertani agar medium [10]. E. coli, B. cereus, S. aureus and C. albicans were obtained from the culture collection of the Department of Microbiology, Faculty of Pharmacy, Mansoura University, Mansoura, Egypt. A. fumigatus 293 was kindly provided from Keller Lab, Madison, WI, UW, USA. Ch. violaceum ATCC 12472 was kindly provided from Prof. Bob Mclean, Department of Biology, Texas State University, San Marcos, TX, USA. All bacterial strains were propagated in LuriaBertani agar medium (Merck, Germany). C. albicans was grown in Sabouraud's medium (E. Merck, Germany) and A. fumigatus 293 was cultivated in glucose minimal medium (E. Merck, Germany). Ampicillin was obtained from EPICO Co., Egypt. Fluconazole was obtained from Pfizer Co., Egypt. Catechin and DMSO 100% were obtained from SigmaAldrich Co., USA. Antibacterial screening (Determination of inhibition zone diameter (mm)) All the bacterial strains were propagated in Luria-Bertani broth (1% peptone, 0.5% yeast extract, 0.5% NaCl) and 6

solidified with 1.5% agar. Melted Muller Hinton agar (50 mL) at 50 °C were seeded with 50 µL of 1x10 CFU/mL of 18 h culture of tested microorganisms. The inoculated agar was mixed and poured into 15-cm-diameter plates to solidify. Wells were made in agar using cork borer. Tested compounds were dissolved in DMSO 100% in eppendorff tubes for final concentration 5 mg/mL. Aliquots each of 100 µL of each compound were applied into the wells, DMSO was also included as a negative control, and ampicillin in a concentration of 5 mg/mL was used as a reference antibacterial agent. The compounds were allowed to diffuse for 2 h at 4 °C and incubated at 37 °C for 24 h [7]. Inhibition zones were measured

-7-

using Vernier caliper and the activity of the tested compounds was estimated in comparison to ampicillin (Table 1). The inhibition zone diameter of DMSO was subtracted from the antibacterial activity of tested compounds. Antibacterial screening (Determination of minimum inhibitory concentration (MIC, µg/mL )) Minimum inhibitory concentration (MIC, µg/mL) of compounds 6j and 6o (with strong antibacterial activity against E. coli and S. aureus) was performed by a serial dilution technique using 96-multiwell microtiter plates [8]. The investigated compounds were dissolved in DMSO 100% to prepare stock solutions of 5000 µg/mL. Two fold serial dilutions of the dissolved compounds were performed in Luria-Bertani broth providing eight different concentrations (2500, 1250, 625, 312.5, 156.25, 78.125, 39.062 and 19.531 µg/mL). Overnight culture of microorganisms were diluted 6

to 1x10 CFU/mL in Luria-Bertani broth and 20 µL of the diluted cultures were added to the test solutions (100 µL) in the wells (one well per concentration per bacterial strain). The plates were incubated at 37 °C for 24 h [8]. MIC was detected visually as the least concentration inhibiting bacterial growth (no turbidity) and the activity of the tested compounds was estimated in comparison to ampicillin (Table 2). Antifungal screening (Determination of inhibition zone diameter (mm)) 3

Sabouraud's medium (50 mL) inoculated with 50 µL of 1x10 CFU/mL of 24 h culture of C. albicans. Glucose 3

minimal medium (50 mL) was inoculated with 50 µL of 1x10 SFU/mL of A. fumigatus 293. Wells were made in agar using cork borer. The tested compounds were dissolved in DMSO 100% in eppendorff tubes for final concentration 5 mg/mL and 100 µL of the test solution was applied in the wells. The standard antifungal drug (fluconazole) was also added at the same concentration and volume to each plate. In addition, DMSO (control solvent) was added to each plate. Plates were incubated at 37 °C for 48 h [9]. Antifungal activity of the tested compounds was determined by measuring the diameter of the inhibition zone (Table 1). The inhibition zone diameter of DMSO was subtracted from the antifungal acrivity of tested compounds. Antifungal screening (Determination of minimum inhibitory concentration (MIC, µg/mL)) Minimum inhibitory concentration (MIC, µg/mL) of compounds 4b, 4c and 6j (with strong antifungal activity against C. albicans) and compounds 4a, 5a, 6j, 6l, 7c and 7d (with strong antifungal activity against A. fumigatus 293) was determined by broth microdilution method using 96-multiwell microtiter plates. The investigated compounds were dissolved in DMSO 100% to prepare stock solutions of 5000 µg/mL. Two fold serial dilutions of the dissolved compounds were performed in the appropriate medium providing eight different concentrations (2500, 1250, 625, 312.5, 6

156.25, 78.125, 39.062 and 19.531 µg/mL). Overnight culture of C. albicans was diluted to 1x10 CFU/mL in 3

Sabouraud's medium and A. fumigatus 293 was diluted to 1x10 SFU/mL in glucose minimal medium. The diluted cultures (20 µL) were added to the test solutions (100 µL) in the wells (one well per concentration). The plates were incubated at 37 °C for 48 h [8]. MIC was detected visually as the least concentration inhibiting fungal growth (no turbidity) and the activity of the tested compounds was estimated in comparison to fluconazole (Table 2).

Antiquorum-sensing screening Cultures were prepared by growing Ch. violaceum ATCC 12472 in Luria-Bertani broth and incubated for 16-18 h in an orbital incubator running at 28 °C and 150 rpm. Cultures were then adjusted to 0.5 McFarland standard (Ca. 1x10

6

CFU/mL). Ch. violaceum (100 µL) was inoculated into Luria-Bertani agar (50 mL), poured into plates and solidified. Wells were made in Luria-Bertani agar medium using cork borer. The tested compounds were dissolved in DMSO 100% in eppendorff tubes for final concentration 5 mg/mL and 100 µL of test solution was applied in the wells. The positive control (catechin) was also added at the same concentration and volume to each plate. The positive control (catechin) was also added at the same concentration and volume to each plate. DMSO (control solvent) was added to each plate. Plates were incubated at 30 °C for 48 h to check the inhibition of pigment production around the well. Bacterial growth inhibition would result in a clear halo around the disc, while a positive quorum sensing inhibition is exhibited by a turbid halo harboring pigmentless bacterial cells of Ch. violaceum ATCC 12472 monitor strain [10]. Bacterial growth inhibition by the tested compounds was measured as radius (r1) in mm, while both growth and pigment inhibition was measured as radius (r2) in mm. The pigment inhibition (QS inhibition) was determined by substracting bacterial growth inhibition (r1) from the total radius (r2), thus; QS inhibition = (r2-r1) in mm (Table 1).

MTT assay for antitumor screening Compounds 4a-e, 5a-c, 6a-r and 7a-d were screened for cytotoxic activity against cervical cancer (Hela) and kidney fibroblast cancer (COS-7) cell lines adopting MTT assay [11-13] and using doxorubicin as a reference cytotoxic agent. Cells were cultured in Roswell Park Memorial Institute (RPMI) 1640 medium with 10% fetal bovine serum, penicillin (100 units/mL) and streptomycin (100 µg/mL) at 37 °C in an atmosphere of 5% CO2 were added. 4

Cells were placed in a 96-multiwell microtiter plate (10 cells/well), for 24 h at 37 °C and in an atmosphere of 5% CO2 before treatment with the compounds to allow attachment of the cells to the wall of the plate. The tested compounds were dissolved in DMSO and diluted with phosphate buffer solution (PBS) to obtain different concentrations. Tested compounds of different concentrations were added to each well and cells were incubated with the compounds for 48 h at 37 °C and in an atmosphere of 5 % CO2. All tests were performed in triplicates. The treated cells were washed with PBS and 100 µL of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide solution (MTT) (5 mg/mL MTT stock in PBS diluted to 1 mg/mL with 10% RPMI-1640 medium) was added. The 96-multiwell plates were read by microarray reader Perkinelmer vector 3V multilabel counter model 1420 (Perkinelmer, Boston, MA) for optical density at 490 nm [11-13]. The relative percentage cell viability was calculated from the following equation:

A

% cell viability =

The relation between surviving fraction and drug concentration is plotted to get the survival curve for cervical cancer (Hela) and kidney fibroblast cancer (COS-7) cell lines. The concentration required for 50% inhibition of cell viability (IC50) was obtained for each compound from the curve fitting using Sigma plot10.
