Abstract

Synthesis of an aromatic cyclic enadione, 2-benzylidene-cyclohexane-1,3-dione (a potential angiogenesis inhibitor), has been done using benzaldehide (50 mmole) and cyclohexane-1,3-dione (50 mmole) as starting materials and NaOH 1.0 N as a catalyst. Odorless and white needle-shape powder has been achieved. The powder was 252.7 mg (2.53 %) and the purity of the powder was 88.81 %. Its melting point was 214.8 oC. The purity of the product was examined by gas chromatography, while the structure elucidation was done using IR spectrometer, 1H-NMR spectrometer, and GC-MS.IR spectrometer showed that the compound had a -C=O bond conjugated to an alkene or a phenyl moiety, methylen groups, and alkene’s -C–H bonds. 1H-NMR spectrometer showed that the compound had benzene moiety and methylen moieties, which were in α and β position to a carbonyl group. GC-MS showed that the molecular weight of the compound was 200 atomic mass unit.Key words: Angiogenesis inhibitor, synthesis, 2-benzylidene-cyclohexane-1,3-dione.

Abstract

One of well-established biological activities for chalcone derivatives is as acetylcholinesterase inhibitors, which can be developed for the therapy of Alzheimer’s disease. Assisted byretrospectively validated structure-based virtual screening (SBVS) protocol to identify potent acetylcholinesterase inhibitors, 80chalcone derivatives were designed and virtually screened. The F-measure value as the parameter of the predictive ability of the SBVS protocol developed in the research presented in this article was 0.413, which was considerably better than the original SBVS protocol (F-measure = 0.226). Among the screened chalcone derivatives two were selected as potential lead compounds to designpotent inhibitors for acetylcholinesterase: 3-[4-(benzyloxy)-3-methoxyphenyl]-1-(4-hydroxy-3-methoxyphenyl)prop-2-en-1-one(3k) and 3-[4-(benzyloxy)-3-methoxyphenyl]-1-(4-hydroxyphenyl)prop-2-en-1-one (4k).

Abstract

By employing Databases of Useful Decoys (DUD) and its enhanced version (DUD-E), several attempts to construct validated Structure-based Virtual Screening (SBVS) protocols to identify cyclooxygenase-2 (COX-2) inhibitors have been performed. Both databases tagged active COX-2 inhibitors for compounds with IC50 values < 1mM. In the search for phytochemicals as natural COX-2 inhibitors, however, most of their IC50 values are in the micromolar range, which will likely be identified as non-inhibitors for COX-2 by the available SBVS protocols. In this article, validation of an SBVS protocol by adding marginal active COX-2 inhibitors from DUD-E as active compounds is presented. Binary quantitative-structure activity relationship analysis by using recursive partition and regression tree method was performed subsequently to optimize the predictive ability of the protocol. The enrichment factor and the F-measure values of the optimized protocol could reach 44.78 and 0.47, respectively. The optimized protocol could identify 1 out of 9 phytochemicals as COX-2 inhibitors.
