An inulin and doxorubicin conjugate for improving cancer therapy.

Chemotherapy is one of the primary treatment mechanisms for treating cancer. Current chemotherapy is systemically delivered and causes significant side effects; therefore the development of new chemotherapeutic agents or enhancing the effectiveness of current chemotherapeutic could prove vital to patients and cancer care. The purpose of this research was to develop a new conjugate composed of doxorubicin (chemotherapeutic) and inulin (polysaccharide chain) and evaluate its potential as a new therapeutic agent for cancer treatment. The synergistic effect of inulin conjugated to doxorubicin has allowed the same cytotoxic response to be maintained or improved at lower doses as compared to doxorubicin. Supporting results include cytotoxicity profiles, calf thymus DNA binding studies, confocal microscopy, and transport studies.
