AB  - The aims of this research were preparation of Juglans nigra husk extracts by employing an ultrasonic-assisted extraction method and process optimization of minerals extraction using response surface methodology. Extracts from J. nigra L. fresh husk were prepared using ethanol (70%, v/v) as a solvent, at different extraction temperatures: 15, 30 and 40 °C, and extraction times: 5, 15, 30, 60 and 80 min. The content of minerals in ethanol extracts was determined using inductively coupled plasma optical emission spectrometry (ICP-OES). The response surface methodology (RSM) was developed to evaluate the effect of two extraction factors as well as to optimize the extraction variables for each mineral individually. The RSM models pointed out 40 °C temperature and extraction time in the range 77–80 min as optimal conditions for extraction of macro- and micro-elements. Results of RSM optimization showed the relative order of maximum obtained yield of macro-elements: K>P>S>Ca>Mg and maximum yield of micro-elements was Si>Zn>Sr>Cu.

AB  - A study of structure cytotoxic-activity relationship of three hydroxy 4-phenyl-coumarins and basic coumarin molecule against two human cell lines (MRC5 fibroblasts and A375 melanoma cells) is presented. Of all investigated compounds the highest cytotoxic activity in both cell lines was determined for 7,8-dihydroxy-4-phenyl coumarin. SAR studies revealed the influence of phenyl group and hydroxyl group's number and position on cytotoxic activity. In addition, to get an insight about their binding preferences at the active site of the receptor (catalytic subunit of cAMP-dependent protein kinase) molecular docking studies were performed. Docking studies suggest that 4-phenyl hydroxycoumarins are potent cAMP-dependent protein kinase inhibitors, better than their analogs without phenyl group. The teratogenic potential was assessed in zebrafish embryo toxicity test and results showed that 4-phenyl dihydroxycoumarins were more while 7-hydroxy-4-phenyl coumarin was less embryo toxic in comparison to coumarin. In order to examine selected 4-phenyl hydroxycoumarins as a new lead compounds the druglikeness of selected 4-phenyl hydroxycoumarins was estimated by using Lipinski's "rule of five". All selected 4-phenyl hydroxycoumarins proved to have satisfying pharmacokinetic profile.
