Edotecarin (formerly ED-749; J-107088; J 107088; PF 804950) is a novel and potent inhibitor of topoisomerase I that can induces single-strand DNA cleavage with IC50 of 50 nM. The novel indolocarbazole edotecarin differs from other topoisomerase I inhibitors both pharmacokinetically and pharmacodynamically. In vitro, it is more potent than camptothecins and has a variable cytotoxic activity in 31 different human cancer cell lines. Edotecarin also possesses greater than additive inhibitory effects on cell proliferation when used in combination with other agents tested in vitro against various cancer cell lines. The present in vivo studies were done to extend the in vitro findings to characterize the antitumor effects of edotecarin when used either alone or in combination with other agents (i.e., 5-fluorouracil, irinotecan, cisplatin, oxaliplatin, and SU11248) in the HCT-116 human colon cancer xenograft model. Treatment effects were based on the delay in onset of an exponential growth of tumors in drug-treated versus vehicle control-treated groups. In all studies, edotecarin was active both as a single agent and in combination with other agents. Combination therapy resulted in greater than additive effects, the extent of which depended on the specific dosage regimen. Toxicity in these experiments was minimal. Of all 359 treated mice, the six that died of toxicity were in the high-dose edotecarin/oxaliplatin group. The results suggest that edotecarin may serve as effective chemotherapy of colon cancer when used as a single agent, in combination with standard regimens and other topoisomerase inhibitors or with novel agents, such as the multitargeted tyrosine kinase inhibitor SU11248.
| ln Vitro |
Edocalin (0.6 μmol/L) enhances DNA-protein complex formation in human colon cancer cells labeled with 3H thymidine in a time-dependent manner [1].

| ln Vivo |
Edotecarin exhibits potent anti-metastatic properties and can enhance the survival rate of mice with intracranial D-456MG glioma by 83% [1]. Tumor growth was delayed by edocaline for a period of time that varied from 10.45 days at the lowest dose (3 mg/kg) to 24.83 days at the maximum dose (100 mg/kg). When edocalin and irinotecan are used in combination, the anticancer activity in vivo is enhanced as compared to when they are used alone [2].

| Additional Infomation |
Edotecarin is a novel, non-camptothecin, DNA topoisomerase I inhibitor. It is member of the class of compounds called indolocarbazoles.
Edotecarin is a synthetic indolocarbazole with antineoplastic activity. Edotecarin inhibits the enzyme topoisomerase I through stabilization of the DNA-enzyme complex and enhanced single-strand DNA cleavage, resulting in inhibition of DNA replication and decreased tumor cell proliferation. (NCI04) Drug Indication Clinical studies with edotecarin have shown activity in subjects with colorectal cancer, esophageal cancer and other solid tumors. Mechanism of Action Edotecarin inhibits the enzyme topoisomerase I through stabilization of the DNA-enzyme complex and enhanced single-strand DNA cleavage, resulting in inhibition of DNA replication and decreased tumor cell proliferation. Pharmacodynamics Edotecarin, formerly J-107088 is a novel, non-camptothecin, DNA topoisomerase-1 inhibitor. It is part of the class of compounds called indolocarbazoles. It is a novel inhibitor of topoisomerase I that induces single-strand DNA cleavage more effectively than NB-506 or camptothecin (CPT) and at different DNA sequences. The DNA-topoisomerase I complexes induced by edotecarin are more stable than those occurring after exposure to CPT or NB-506. The antitumor activity of edotecarin is less cell cycle dependent than other topoisomerase I inhibitors. Being an indolocarbazole, it is structurally related to staurosporine but does not possess protein kinase inhibitory properties. The antitumor activity of edotecarin has been tested in vitro and in vivo, and inhibition of tumor growth has been observed in breast, cervix, pharynx, lung, prostate, colon, gastric, and hepatic cancer models. Edotecarin is effective on cells that have acquired resistance related to P-glycoprotein. In vitro synergy has been demonstrated when edotecarin was tested in combination with cisplatin, 5-fluorouracil, etoposide, paclitaxel, doxorubicin, vincristine, CPT, and gemcitabine. |
