P. Magiatis et al., SYNTHESIS AND CYTOTOXIC ACTIVITY OF PYRANOCOUMARINS OF THE SESELIN AND XANTHYLETIN SERIES, Journal of natural products, 61(8), 1998, pp. 982-986
The synthesis of known (3-6) and new (7-10 and 14-22) coumarins in the
seselin and xanthyletin series is described. The cytotoxic activity o
f compounds 3-22 was carried out in vitro on L-1210 cells. The most ac
tive compounds were 9, 16, 18, and 20 in the seselin series and 10, 17
, and 19 in the xanthyletin series. Structure-activity relationships a
re discussed.
