Additional Information

LU 79553 is a novel bis-naphthalimide which is highly cytotoxic in vitro with EC50 (concentration required for 50% inhibition of growth) ranging from 2 x 10(-7) to 5 x 10(-10) M. A number of studies were conducted to examine its antitumor activity in human xenograft models.  Complete regression of MX-1 (mammary carcinoma) xenografts was observed when LU 79553 was administered i.v. daily for 5 doses at 20 mg/kg (2 cycles starting on Days 6 and 20) or every 3 days for 2 doses at 55 mg/kg (2 cycles starting on Days 6 and 13) or every 7 days for 4 doses. Complete regression was also seen in the MX-1 model when tumors were staged at 1-2 g prior to the initiation of treatment. Regressions (complete or partial) were observed in the LX-1 (lung), CX-1 (colon), DLD (colon), and LOX (melanoma) xenograft models. A significant increase in the median survival time of OVCAR-3- (ovarian carcinoma) bearing mice was noted in LU 79553-treated animals (treated/control = 195%). The excellent activity of this compound in such a wide variety of tumor types suggests LU 79553 merits further investigation in clinical trials. see: http://www.ncbi.nlm.nih.gov/pubmed/7867004.
