CPT, an alkaloid extract, displays anticancer activity as an inhibitor of DNA topoisomerase I. This action prevents resealing of DNA following DNA synthesis, halting nucleic acid synthesis and cell death.
Camptothecin 20-propionate monohydrate
WebCamptothecin (CPT, 1) is a plant alkaloid from the Camptotheca acuminata tree. 83 In in vitro assay, camptothecin exhibited excellent topoisomerase I inhibitory activity but poor water solubility (2.5×10 −3 mg ml −1) and unpredictable toxicity. In an attempt to improve both the toxicological profile and the water solubility, a variety of ... Web(S)-(+)-Camptothecin binds irreversibly to the DNA-topoisomerase I complex, inhibiting the reassociation of DNA after cleavage by topoisomerase I and traps the enzyme in a covalent linkage with DNA. The enzyme complex is ubiquinated and destroyed by the 26S proteasome, thus depleting cellular topoisomerase I. Blocks the cell cycle in S-phase at ... hugo sofa rove concepts
