Popis: A doxorubicin and [D-Lys(6)]Luteinizing Hormone-Releasing Hormone (LH-RH) conjugate, AN-152, was designed to target LH-RH receptor positive cells. AN-152 is more potent against a specific group of cancers than doxorubicin and has less peripheral toxicity. This therapy is potentially efficacious against many other types of malignancies. Here, AN-152 was tested on oral (KB) and laryngeal (HEp-2) carcinoma cells. LH-RH receptor presence was demonstrated by displacement binding assays. Cells were treated with 10 nM EGF or left untreated, then exposed to 0-10 microM AN-152. Cytotoxicity was assessed by MTT assay to determine ED(50) values. AN-152 association with the cells was monitored using two-photon laser scanning microscopy. AN-152 was more potent than doxorubicin in both KB and HEp-2 cell lines (P
