Nanotechnology Based Targeting Strategies for the Delivery of Camptothecin

Part of the Sustainable Agriculture Reviews book series (SARV, volume 44)


Camptothecin is a potent anti-cancer drug which has shown appreciable anti-tumor activity against a broad spectrum of cancers such as breast, ovarian, colon, lung and stomach. The water insolubility property, rapid conversion of its bioactive lactone form to inactive carboxylate form under physiological condition, incidence of drug resistance and the associated off-target side effects due to extended use of campothecin restricts its widespread clinical usage. The development of novel treatment modalities is therefore the demand of era. The last two decades have already evidenced the explosive growth of nanotechnology channeling into plethora of innovations in therapeutic domains, the main dominance being the ability to target the tumor tissues either passively or actively.

This chapter deals in brief with the origin and mode of action of campothecin, the drawbacks associated with the use of the conventional drug (campothecin), the structural modifications carried out to overcome the stability and solubility issues as well as the novel targeted drug delivery platforms (passive and active targeting) that has been explored for the treatment of solid tumors. The structure activity relationship of different campothecin derivatives are elaborately discussed. The mechanism of action of passive and active targeting illustrates the wide applicability of campothecin as an anticancer lead against different solid tumors and cell lines.
