    Notizen: Abstract L1210 leukemia cells, because of their rapid growth rate in suspension culture and high growth fraction, are ideally suited to screen in vitro for cytotoxic compounds. Although L1210 cells may mimic rapidly growing tumors, they have not been effective in selecting agents active against slow growing solid tumors. We expected that cell lines originating from human solid tumors, because of their slower growth rate and lower S phase fraction, would be more drug resistant than L1210. Therefore, we compared ten human tumor cell lines (5 melanomas, 4 colon carcinomas and 1 small cell lung carcinoma) to L1210 growth inhibition by 9 anti-tumor drugs. Not one human tumor cell line was consistently more resistant to all nine drugs than L1210 when the cells were exposed to drugs for about 2 doubling times. The drug sensitivity of 2 cell lines (L1210 and SK MEL 28) was again determined after a short term (2 hr) exposure and using growth inhibition and cell survival as end points. For both end points these two cell lines exhibited a random pattern of sensitivity to the drugs tested. Cell kill showed an order of sensitivity different than growth inhibition. The implication of these findings for drug-screening is discussed.

    Notizen: Summary Adozelesin (U-73975) is a potent synthetic cyclopropylpyrroloindole (CPI) analog of the cytotoxic DNA-binding antibiotic, CC-1065. In contrast to the natural product, adozelesin and related CPI analogs do not cause delayed death in non-tumored mice. Adozelesin, selected from a series of analogs for its superior in vivo antitumor activity and ease of formulation, is highly active when administered i.v. against i.p.- or s.c.-implanted murine tumors, including L1210 leukemia, B16 melanoma, M5076 sarcoma, and colon 38 carcinoma, and produces long-term survivors in mice bearing i.v.-inoculated L1210 and Lewis lung carcinoma. Modest activity is shown against the highly drug-resistant pancreas 02 carcinoma. Adozelesin is also highly effective against human tumor xenografts s.c.-implanted in athymic (nude) mice, including colon CX-1 adenocarcinoma, lung LX-1 tumor, clear cell Caki-1 carcinoma, and ovarian 2780 carcinoma. Its broad spectrum of in vivo activity compares favorably with three widely used antitumor drugs, i.e. cisplatin, cyclophosphamide, and doxorubicin. Adozelesin appears to be more effective than these drugs in the treatment of very resistant tumors such as s.c.-implanted mouse B16 melanoma, pancreatic 02 carcinoma, and human colon CX-1 and human lung LX-1 tumor xenografts. Based on its high potency and high efficacy against a broad spectrum of experimental tumors, adozelesin was chosen for clinical investigation and development.
