Activity against murine leukemia cells

The antineoplastic activity of vanadium compounds has been studied for some time. In 1979, the metalocene compound, biscyclopentadienyldichloro-Vanadium(IV), (C5H5)VCI2, was found to have antitumor activity [161], The compound inhibited the growth of various cancer cell lines and the growth of solid tumors in vivo. Vanadium(V) peroxocomplexes with known insulin-mimetic activity were shown to have antitumor activity against murine leukemia cells at that time. Vanadocene compounds are now known to induce apoptosis in cell lines. The apoptotic signal... 

The related stannylpyrrole 90, which was reported by Dubac [72], has been used to synthesize the sponge metabolite mycalazol 11 (91) and related compounds, which have activity against the P388 murine leukemia cell line [74]. 

In 1991, Kojiri et al. reported the isolation of BE-13793C (344), an alkaloid isomeric with the arcyriaflavins C (347) and D (348) (see Scheme 2.89), from the culture broth of Streptoverticillium moharaense strain BA 13793 collected in Seto, Aichi Perfecture, Japan. BE-13793C (344) showed strong inhibitory activity against topoisomerases I and II and inhibited the growth of doxorubicin-resistant or vincristine-resistant P-388 murine leukemia cell lines, as well as their parent P-388 cell line (330). 

Several groups have used this reaction in recent years to prepare biologically active molecules. Benzothiophene derivatives 93, prepared from Gewald products 92 in three steps via a palladium-mediated aromatization reaction, (Scheme 21) were tested for their antiproliferative activity and inhibition of tubulin polymerization [55]. Several compounds showed inhibitory effects against murine leukemia (L1210), murine mammary carcinoma (FM3A) and human T-lymphoblastoid (Molt/4 and GEM) cells. For most of the compounds, there was a positive...
