Comparative pharmacokinetics of KRN8602, a new morpholino anthracycline, and adriamycin in tumor-bearing mice. Cancer chemotherapy and pharmacology, 1996, Volume: 38, Issue:5 It has been reported that KRN8602 shows antitumor effects similar or superior to those of Adriamycin (ADM) against several murine and human cell lines and has been found to be effective against multidrug resistant tumor cells. We investigated the pharmacokinetics of KRN8602, a new morpholino anthracycline, in comparison with ADM in mice bearing colon26 adenocarcinoma. After intravenous administration, both drugs disappeared triexponentially from the plasma and KRN8602 was eliminated faster than ADM. The rate of elimination of KRN8602 from tissues was also faster than than of ADM. The relative order of the area under the curve (AUC) of KRN8602 was spleen > tumor > small intestine > lung > kidney > heart > liver > brain > plasma, while that of ADM was spleen > kidney > lung > liver > heart > small intestine > tumor > plasma. ADM was not detectable in the brain. The AUC of KRN8602 was higher than that of ADM in the tumor and brain, but it was lower in other tissues. The tissue-to-plasma concentration ratio (KPapp) of KRN8602 was higher than that of ADM in the tumor, spleen, small intestine and brain. KRN8602 was metabolized to several metabolites. The concentrations of M1 and M2 (glycoside-type metabolites) was relatively high in the spleen. M3 (aglycone-type metabolite) showed a very high AUC ratio in the liver (34%). In tumor, M1 and M2 concentrations were low and M3 was not detected. KRN8602 had a greater activity than ADM and M2 had a cytotoxic activity similar to KRN8602 against colon26 cells in an MTT assay. These results suggest that the strong antitumor effect of KRN8602 against colon26 is due not only to its strong cytotoxic activity but also to its marked transferability into tumors. KRN8602 shows better selective toxicity than ADM, because KRN8602 is more selective for tumors than ADM and less is transferred to normal tissues.

Comparative pharmacokinetics of KRN8602, a new morpholino anthracycline, and adriamycin in tumor-bearing mice.

It has been reported that KRN8602 shows antitumor effects similar or superior to those of Adriamycin (ADM) against several murine and human cell lines and has been found to be effective against multidrug resistant tumor cells. We investigated the pharmacokinetics of KRN8602, a new morpholino anthracycline, in comparison with ADM in mice bearing colon26 adenocarcinoma.
