Bulbophyllum Odoratissimum에서 추출한 새로운 페난트렌, 3,7-Dihydroxy-2,4,6-trimethoxyphenanthrene

3,7-Dihydroxy-2,4,6-trimethoxyphenanthrene, A New Phenanthrene from Bulbophyllum Odoratissimum

Efficient stereoselective synthesis of α,β-Unsaturated acids, α-Cyanoacrylonitriles and α-Cyanoacrylates has been carried out in the presence of NaHSO4·SiO2 under solvent?free conditions with an E-geometry.

A new phenanthrene derivative 3,7-dihydroxy-2,4,6-trimethoxyphenanthrene was isolated from the all plant of Bulbophyllum odoratissimum, and its structure was elucidated by extensive spectral studies and chemical transformation. The compound displayed cytotoxicity against the growth of human leukemia cell lines K562 and HL-60, human lung adenocarcinoma A549, human hepatoma BEL-7402 and human stomach cancer cell lines SGC-7901 with IC50 values of 14.23, 10.02, 3.42, 15.36 and 1.13 mg/ml respectively.
