A. Andreani et al., POTENTIAL ANTITUMOR AGENTS .25. SYNTHESIS AND CYTOTOXIC ACTIVITY OF -CHLORO-3-INDOLYLMETHYLENE)1,3-DIHYDROINDOL-2-ONES, Anticancer research, 16(6B), 1996, pp. 3585-3588
The Knoevenagel reaction between 2-indolinones and 2-chloroindolaldehy
des gave chloro-3-indolylmethylene)-1,3-dihydroindol-2-ones which were
tested as potential antitumor agents on cultures of HeLa cells. 2-Chl
oro derivatives with at least one unsubstituted NH group, are promisin
g candidates for further investigation.
