Description: Genz-644282, also known as SAR402674, is a non-camptothecin inhibitor of topoisomerase I with potential antineoplastic activity. Topoisomerase I inhibitor Genz-644282 binds to and inhibits the enzyme topoisomerase I, which may result in the inhibition of repair of single-strand DNA breaks, DNA replication, and tumor cell growth in susceptible tumor cell populations.

| Biological target: | Genz-644282 is a non-camptothecin topoisomerase I inhibitor, used for cancer research. |
| In vitro activity: | The induction and stability of Top1cc produced by Genz-644282 were evaluated in human colon cancer carcinoma HCT116 cells using the Immunocomplex of Enzyme (ICE) and alkaline elution assays. Figure 3A shows that Genz-644282 is more potent at trapping Top1-DNA covalent cleavage complexes than either CPT or TPT at the same concentration. Additionally, even metabolites of Genz-644282, Genz-649974, Genz-649975, and Genz-649978, are active and effective at trapping Top1 with Genz-649978 being less potent than the others (Fig. 3B).

| In vivo activity: | Following i.v. administration of Genz-644282 (2 mg/kg) to nu/nu mice, the mean blood clearance, volume of distribution, and terminal half-life were 21.8 mL/min/kg, 5.44 L/kg, and 5.14 hours, respectively. An i.v. injection of Genz-644282 (2 mg/kg) to nu/nu mice bearing NCI-H460 human tumor xenografts resulted in plasma PK parameters of 104 mL/min/kg mean clearance, a 49.3-L/kg volume of distribution, and terminal half-life of 8.14 hours. The mean area under the curve (AUC) in tumor tissues (9,690 ng·h/mL) was approximately 30-fold higher than that observed in plasma (319 ng·h/mL), showing that Genz-644282 has a high penetration into tumor tissue in the xenograft model. For an analysis of the PK/PD relationship of Genz-644282, this study compared the exponential growth of tumors in control mice with tumor growth in the Genz-644282–treated mice. The growth decreased by a factor proportional to drug concentration. The estimated average tumor concentration of Genz-644282 at steady state ranged from 130 to 519 nmol/L, or 24- to 96-fold higher than the in vitro IC90 (5.4 nmol/L), thus predicting that the tumor would be responsive to treatment.
