Crystal structure and DNA binding properties of khellin oxime
Abstract The dried fruits of Ammi visnaga were subjected to Soxhlet extraction with water, followed by hexane and purified by column chromatography to yield Khellin ( 1) . Oximation of 1 yielded khellin oxime ( 2), crystallized by slow evaporation from CH 2 Cl 2 :EtOAc (6:3), characterized by single-crystal X-ray diffraction method for the first time. The DNA binding affinities of the 1 and 2 have been appraised
