    Author: Liu M, Xu PL, Wang ZJ.
    Journal: Yao Xue Xue Bao; 1992; 27(5):388-93. PubMed ID: 1442062.
    Abstract:
    According to drug combination principle 26 substituted benzaldehyde/cinnamicaldehyde semicarbazones were synthesized. Twelve of which were not found in literature. The structures of the title compounds were confirmed by elemental and IR, UV, 1HNMR and MS analyses. Thirteen compounds were screened in vivo against Ehrlich ascites tumor cells. Four compounds (VIIf, VIIg, VIIh, VIIm) showed strong antitumor activity. The percent increase in life span were between 46.1%-91.1%. 3-Methoxy-4-hydroxy and 3-methoxy-4-acetyloxy-cinnamicaldehyde selenosemicarbazones showed stronger activity and less toxicity with increase of life span of 76.5% (300 mg/kg) and 91.1% (60 mg/kg), respectively. They were worthy to be studied further.
