Product Information
| Description: | O-acetylcamptothecin is a derivative of camptothecin, a naturally occurring alkaloid extracted from the bark of the Chinese tree Camptotheca acuminata. Camptothecin and its derivatives are primarily known for their potent anticancer properties, particularly through their action as inhibitors of topoisomerase I, an enzyme critical for DNA replication and transcription. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
