Camptothecin (CPT), a pyrrolo quinoline alkaloid, is one of the most promising anticancer drugs of the 21st century. The compound was first isolated from the Chinese deciduous tree, Camptotheca acuminata. CPT exhibits a broad spectrum of antitumor activity both under in vitro and in vivo conditions. Irinotecan (CPT11) and Topotecan (TPT), two water-soluble derivatives of CPT, have been approved by the United States Food and Drug Administration for treating colorectal and ovarian cancers as well as against several types of brain tumor in children. Although CPT has been reported to exist in several species, the highest concentration (about 0.3 %) to date has been realized from Nothapodytes nimmoniana. The tree commonly referred to as “stinking tree” is native to warmer regions of South India. In the last few decades, driven by the enormous demand for CPT, there has been a decline of at least 20 % in the population, leading to red listing of the species. In recent years, efforts have been initiated in India to identify high-yielding individuals and populations of N. nimmoniana in its natural distribution range with the ultimate aim of using these lines to develop clonal orchards, as well as in developing in vitro production systems. In this chapter, we briefly review the overall status of N. nimmoniana as a source of CPT. Drawing upon existing literature as well as ongoing work at our laboratory, we discuss the basic patterns of accumulation of CPT in N. nimmoniana. We review the population variability for CPT accumulation along the distributional range of the species in the Western Ghats, India. Using a relatively new tool, namely the ecological niche model, we predict the chemical hot-spots of the species in the Western Ghats and offer a test of this prediction. Finally, we discuss strategies for a sustainable model of extraction of CPT from N.nimmoniana.
