AB  - Chemical and biocatalytic synthesis of seven previously undescribed marchantin A ester derivatives has been presented. Chemical synthesis afforded three peresterified bisbibenzyl products (TE1-TE3), while enzymatic method, using lipase, produced regioselective monoester derivatives (ME1-ME4). The antiproliferative activities of all prepared derivatives of marchantin A were tested on MRC-5 healthy human lung fibroblast, A549 human lung cancer, and MDA-MB-231 human breast cancer cell lines. All tested esters were less cytotoxic in comparison to marchantin A, but they also exhibited lower cytotoxicity against healthy cells. Monoesters displayed higher cytotoxic activities than the corresponding peresterified products, presumably due to the presence of free catechol group. Monohexanoyl ester ME3 displayed the same IC50 like marchantin A against MDA-MB-231 cells, but the selectivity was higher. In this way, regioselective enzymatic monoesterification enhanced selectivity of marchantin A. ME3 was also the most active among all derivatives against lung cancer cells A549 with the slightly lower activity and selectivity in comparison to marchantin A.

AB  - Seven new bisbibenzyls (1-7) were isolated from the methanol extract of the liverwort Lunularia cruciata along with one previously known bibenzyl and five known bisbibenzyls. The structures of compounds 1-7 were elucidated on the basis of the spectroscopic data. These newly isolated bisbibenzyls may be divided into two groups, the acyclic bisbibenzyls, perrottetins (1-3), and the cyclic analogues, riccardins (4-7). Besides standard perrottetin and riccardin structures (1 and 4, respectively), they contain phenanthrene (3 and 5), dihydrophenanthrene (2), and quinone moieties (6 and 7), rarely found in natural products. The new compounds 3 and 5, as well as the known riccardin G, exhibited cytotoxic activity against the A549 lung cancer cell line with IC 50 values of 5.0, 5.0, and 2.5 μM, respectively.

AB  - A number of potentially useful compounds with various biological activities can be obtained from plant metabolites by microorganisms. In present research, essential oil of Calamintha glandulosa was subjected to the biotransformation process by mycromicete Aspergillus niger. GC/MS analyses of the original and biotransformed essential oil have revealed six(1-6) biotransformed compounds from one of the main component-limonene and one biotransformed product (7) originating from the less abundant component-thymol. Piperitone epoxide and piperitenone epoxide, the most abundant components of the original oil, were not biotransformed but gave three artefacts (A1, A2, B1) due to the acidic conditions formed in A. niger medium. Compounds 5, 6 as well as 7 have not been previously found as a biotransformation products of limonene (5 and 6) and thymol (7), respectively. New products (5, 6, and 7) together with the artefacts, were isolated by silica gel column chromatography followed by preparative silica gel thin layer chromatography, and their structures were established by a combination of 1D and 2D NMR spectra and GC/MS data. Biotransformation has one more confirmed as useful method, complementary to synthesis, for obtaining different type of molecules.

Compounds 5, 6 as well as 7 have not been previously found as a biotransformation products of limonene (5 and 6) and thymol (7), respectively. New products (5, 6, and 7) together with the artefacts, were isolated by silica gel column chromatography followed by preparative silica gel thin layer chromatography, and their structures were established by a combination of 1D and 2D NMR spectra and GC/MS data. Biotransformation has one more confirmed as useful method, complementary to synthesis, for obtaining different type of molecules.",

AB  - The chemical composition, antimicrobial and antiquorum sensing activity of the essential oil of Micromeria thymifolia (Scop.) Fritsch were investigated. Limonene, piperitone epoxide and piperitenone epoxide were found as the main constituents using a gas chromatography-mass spectrometry technique. In vitro antimicrobial activity of the oil was tested against six bacterial and seven fungal strains and high antimicrobial potential was noticed. Minimum inhibitory concentration varied from 0.031 mg/mL to 0.5 mg/mL for bacterial and 0.062 mg/mL to 0.5 mg/mL for fungal strains. The antiquorum properties of the essential oil were evaluated on Pseudomonas aeruginosa PAO1. The oil was tested at subMiC concentrations for anti-quorum sensing activity. The analyses on quorum-sensing functions have been carried out by evaluating twitching and swarming of bacterial cultures and the total amount of pyocyanin production produced by P. aeruginosa. This study showed that M thymifolia essential oil exhibited antiquorum sensing activity and may be used as an antipathogenic drug.
