uptake studies showed that the conjugates were 6–10 times selective for breast cancerous cells (MCF-7 and MDA-MB-435) over noncancerous cells (HUVECs and MCF-10A). Conjugate 1 displayed similar toxicity as free Dox toward the breast cancerous cells and was about 40 times less toxic toward the noncancerous cells and 4-fold more toxic toward the Dox resistant MDA-MB-435-MDR cells than the free Dox.

The amino group of doxorubicin I is reacted with bis-NHS-ester linkers 6, or anhydrides 13 to offer in high yield modified doxorubicins 7-12 and 14-16, respectively. Compounds 7-12 are mono-NHS-esters, and can be directly coupled with melanotransferrin (p97), a useful vector with the ability to cross the blood-brain barrier, to yield the expected doxorubicin-p97 conjugates. Upon activating the carboxylic group with BTTU, compound 14-16 could be used in the same reaction. Structurally, the amino group of doxorubicin is covalently bonded to the amino groups of p97. The conjugates are potential candidates for treatment of brain tumors.
Drug targeting to decrease cardiotoxicity – determination of the cytotoxic effect of GnRH-based conjugates containing doxorubicin, daunorubicin and methotrexate on human cardiomyocytes and endothelial cells
difference to the control was analysed. Results: Doxorubicin and daunorubicin exhibited a cytotoxic effect on both cell types, at the highest concentrations tested. Doxorubicin-based conjugates (AN-152, GnRH-III(Dox-O-glut), GnRH-III(Dox-glut-GFLG) and GnRH-III(Dox=Aoa-GFLG) showed the same cytotoxic effect on cardiomyocytes. Among the daunorubicin-based conjugates, [4Lys(Ac)]-GnRH-III(Dau=Aoa), GnRH-III(Dau=Aoa-YRRL)
