  Geiparvarin Analogues: Synthesis and Anticancer Evaluation ofα-Methylidene-γ-butyrolactone-Bearing Coumarins

  摘要：

  To determine some of the structural features of geiparvarin that account for its cytostatic activity in vitro, certain geiparvarin analogues modified in the furan-3(2H)-one moiety and the alkenyloxy substituent were synthesized and tested against the growth of 60 human cancer cell lines derived from nine cancer-cell types. These compounds demonstrated a strong growth-inhibitory activity against leukemia cell lines but were relatively inactive against non-small-cell lung cancers and CNS cancers. Comparison of the mean log GI, values of gamma-[(E)-1-methylprop-1-enyl]-alpha-methylidene-gamma-butyrolactones 7-9 revealed that 7-[(E)-3-(2,3,4,5-tetrahydro-4-methylidene-5-oxofuran-2-yl)but-2-enyloxy]-2H-1-benzopyran-2-one (8: - 5.47) was more active than its 6-substituted counterpart 7 (- 5.21) and its 3-chloro-4-methyl derivative 9 (- 5.31) and had a potency similar to that of geiparvarin (log GI(50) = - 5.41). These results indicated that the furan-3(2H)-one moiety of geiparvarin could be replaced by an alpha-methylidene-gamma-butyrolactone unit without losing the anticancer potency, (:nd that the best substitution site at the coumarin moiety was C(7). The alkenyloxy substituent of 8 was also replaced by a methoxy substituent. Among these alpha-methylidene-gamma-butyrolactones, 7-[(2,3,4,5-tetrahydro-4-methylidene-5-oxo-2-phenyliuran-2-yl)methoxy]-2H-1-benzopyran-2-one (1l) was the most potent with a mean log GI(50) value of - 5.83 and a range value of 132(10(212)).
