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].
