Chromene chalcones from Tephrosia carrollii and the revised structure of Oaracacin.
نویسندگان
چکیده
The aerial parts of Tephrosia carrollii afforded two chromene chalcones. Their structures and stereochemistry were established by spectroscopic methods. The structure of oaxacacin was revised and confirmed by X-ray diffraction. In this paper, we describe the isolation of the chalcone known as "oaxacacin" and the new chalcone named epoxyobovatachalcone. The compound der. oaxacacin was found to be identical with obovatachalcone based on spectroscopic evidence and X-ray diffraction.

Chalcone and chromene motifs are synthetic or naturally occurring scaffolds with significant cytotoxic profile. Two types of novel regioisomeric chromene-chalcone hybrids, namely 1-(6-chloro or 6-methoxy-2H-chromen-3-yl)-3-phenylprop-2-en-1-one (Type A) and 3-(6-chloro or 6-methoxy-2H-chromen-3-yl)-1-phenylprop-2-en-1-one (Type B), both with different substituents on the phenyl ring attached to...
متن کاملStructure and isomeric studies of 1,3-diaryl-H-benzo[f]chromene, catalyst effect or thermodynamic stability? An ab initio study
Two possible isomers of some 1,3-diaryl-H-benzo[f]chromene have been studied using density functional theory. Structures of E1 and E2 isomers were optimized at the B3LYP and MP2 levels with different basis sets. The total electronic energies show that E2 isomer is about 3-5 kcal/mol more stable than E1 isomer and this energy difference is attributed to the planarity of heterocyclic ring and mor...

Cancer is a complex and life-threatening disease involving uncontrollable cell proliferation, evading apoptosis, and metastasis. Despite recent developments in cancer chemotherapy, there are no effective broad spectrum anticancer agents that could selectively target cancer cells. Thus, designing and discovering new efficient and selective anticancer agents are urgent needs. It is important that...
متن کاملFlemingins G-O, cytotoxic and antioxidant constituents of the leaves of Flemingia grahamiana.
The known flemingins A-C (1-3) and nine new chalcones, named flemingins G-O (4-12), along with deoxyhomoflemingin (13) and emodin (14) were isolated from a leaf extract of Flemingia grahamiana. The isolated chalcones were found to have a geranyl substituent modified into a chromene ring possessing a residual chain, as shown by spectroscopic methods. The leaf extract showed an IC50 value of 5.9 ...
