α-Santalol derivatives from Santalum album and their cytotoxic activities.
A bioassay-guided fractionation of the heartwood of Santalum album led to the isolation of seven α-santalol derivatives including (9S,10E)-9-hydroxy-α-santalal, (10R,11S)-10,11-dihydroxy-α-santalol, (9E)-11,13-dihydroxy-α-santalol, and (10E)-12-hydroxy-α-santalic acid. Their structures were determined on the basis of results of spectroscopic analysis, including two-dimensional (2D) NMR spectros...
متن کاملLignans from Santalum album and their cytotoxic activities.
A new neolignan, (7R,8R)-5-O-demethylbilagrewin (1), together with four known lignans (2-5), were isolated from the heartwood of Santalum album (Santalaceae). The structure of 1 was determined by analysis of extensive spectroscopic data. The isolated compounds and derivatives were evaluated for their cytotoxic activities against HL-60 human promyelocytic leukemia cells and A549 human lung adeno...
متن کاملMutagenic, Anti-Mutagenic and Cytotoxic Activities of Artediffusin (Tehranolide), in vitro, extracted from Artemisia diffusa
Background: Artediffusin is a sesquiterpene lactone with an endoperoxide group which has been isolated from Artemisia diffusa. Artemisia has always been of great botanical and pharmaceutical interest and is useful in traditional medicines for the treatment of a variety of diseases and complaints. The aims of the present study were to evaluate the cytotoxic, mutagenic and anti-mutagenic activiti...
متن کاملComparison of bactericidal and cytotoxic activities of trichogin analogs
Peptaibiotics are a group of membrane active peptides of fungal origin. They typically contain α-aminoisobutyric acid (Aib; 1-letter code, U) and other non-coded residues (Toniolo and Brückner, 2009; Neumann et al., 2015; Benedett et al., 1982) [1], [2], [3] stabilizing their helical structure. Peptaibols are peptaibiotics carrying a 1, 2-aminoalcohol at the C-terminus. When a fatty acid chain ...
متن کاملSynthesis, Anti-Inflammatory and Anti- Nociceptive Activities and Cytotoxic Effect of Novel Thiazolidin-4-ones Derivatives as Selective Cyclooxygenase (COX-2) Inhibitors
Objective(s): Nowadays, COX- 2 inhibitors such as valdecoxib are removed from the market because of their cardiovascular toxicity and their potential to increase the risk of strokes. In response to this, medicinal chemists have attempted to synthesize new classes of COX-2 Inhibitors. Materials and Methods: In this study, three novel analogues of thiazolidin-4-ones derivatives ...
