9-Amino Camptothecin is a derivative of Camptothecin (C175150), as antitumor agent. | [Definition]
ChEBI: 9-Aminocamptothecin is a pyranoindolizinoquinoline. | [Biological Activity]
9-amino camptothecin is a topoisomerase i inhibitor [1][2].dna topoisomerases relax dna torsional strain generated during replication, transcription, recombination, repair, and chromosome condensation. the relaxation of dna supercoiling by topoisomerase i is enabled by a mechanism of controlled rotation around a transient dna single-strand break. camptothecin (cpt) is isolated from the bark of the chinese tree camptotheca accuminata [3].9-amino camptothecin, a water-soluble camptothecin analogue, is a topoisomerase i inhibitor. in human ht-29 colon adenocarcinoma, 9-amino camptothecin (9-ac) exhibited cytotoxicity with ic50 value of 19 nm. 9-ac also induced dna damage in whole cells and nuclei at a concenstration of 85 nm and 21 nm, respectively [1].9-amino camptothecin had greater activity than camptothecin against human tumour xenografts, including lewis lung carcinoma and b16 melanoma. 9-ac had entered phase ii trials. in patients with advanced solid tumours, 9-amino camptothecin exhibited anti-tumor activity [1][2]. | [References]
