Abstract: A compound of Formula I or a pharmaceutically acceptable salt thereof (wherein X, Y, Z and n are defined herein). These compounds are useful in the treatment of diseases mediated by topoisomerase I enzyme such as cancers. Also provided are processes for the preparation of compounds of Formula I. The compounds are more water soluble, stable in buffer solution at various pH, and exhibit better anti-tumor activity and rapid release of SN-38 in tumor microenvironments.
