A new butenolide derivative (1), along with three known compounds (2-4) were isolated from the MeOH extract of brown alga Sargassum micracanthum. The structures 1 to 4 determined by analyses 1D and 2D NMR mass spectroscopic data. identified as (5 E,10 Z)-6,10,14-trimethylpentadeca-5,10-dien-2,12-dione (2), E,9 E)-6,10,14-trimethylpentadeca-5,9-dien-2,12-dione (3), (-)-loliolide (4) comparing th...
Three new abietane-type diterpenoids, 7a-butoxyabieta-8,12-diene-11,14-dione (1), 6a,7a-dihydroxyabieta-8,12-dien-11,14-dione (2), and 6a,7b-dihydroxyabieta8,12-diene-11,14-dione (3) were isolated from the bark of Cryptomeria japonica D. Don. Their structures were established by means of 1D and 2D NMR, IR, UV, and HR-EI-MS spectra and comparison with the data of known analogues. ã 2016 Publishe...
In the title compound, C(15)H(10)FNO(3), the dihedral angle between the isoindoline-1,3-dione and 3-fluoro-4-methyl-phenol groups is 86.88 (8)°. The isoindoline-1,3-dione fragment is almost planar, with an r.m.s. deviation of 0.0154 Å within the group. Inter-molecular C-H⋯O hydrogen bonds generate C(6) chains running parallel to the [010] direction.
Novel benzimidazolo indane-1, 3-dione derivatives were synthesized and characterized by IR, HNMRand Mass spectral analysis. Biological screening of synthesized compounds allowed the identification of some novelanthelmintic agents bearing indane-1, 3-dione and benzimidazole scaffolds. Some of these compounds exhibited promisinganthelmintic activities.

Name: (1′S,6′R)-7-Chloro-2′,4,6-trimethoxy-6′-methylspiro[benzofuran-2(3H),1′-[2]cyclohexene]-3,4′-dione IUPAC Systematic Name: 7-Chloro-2′,4,6-trimethoxy-6′β-methylspiro[benzofuran-2(3H),1′-[2]cyclohexene]-3,4′-dione Synonyms: (2S,4′R)-7-Chloro-2′,4,6-trimethoxy-4′-methyl...
because of the importance of microbial metabolites of cholesterol as precursors in the synthesis of steroidal drugs, we decided to study the ability of arthrobacter simplex to degrade cholesterol. arthrobacter simplex cleaves the side chain of cholesterol in the presence of 2,2'-dipyridyl and produces 4-androstene-3,17- dione (ad) and androsta- 1,4-diene-3,17-dione(add). two other intermed...
Jun/Fos, a crucial factor in transmitting the tumor-promoting signal from the extracellular environment to the nuclear transcription machinery, has a dimerization interface possessing several coiled structural properties. Jun and Fos can interact with the DNA regulatory region, AP-1 (Activator Protein-1), which is composed of 5'-TGAC/GTCA-3'. Curcumin is a well-known anticancer and anti-inflamm...
