Hydroxycamptothecin for injection

Hydroxycamptothecin (HCPT) is a cell cycle-specific drug that mainly acts in the S phase. Recently, it has been found to have a targeted and selective inhibitory effect on DNA topoisomerase I, which catalyzes the unwinding of supercoiled DNA for replication and transcription. This product inhibits TOPOI and inhibits the replication and transcription of cancer cells. This product has no obvious cross-resistance with other commonly used anticancer drugs.

The main ingredient of this product is hydroxycamptothecin

This product is a yellow freeze-dried loose block or powder of hydroxycamptothecin, odorless, easily soluble in water. The pH value of the aqueous solution is 8.0-9.5.

It is suitable for malignant tumors such as primary liver cancer, gastric cancer, bladder cancer, rectal cancer, non-small cell lung cancer, head and neck epithelial cancer, leukemia, etc.
