Camptothecin – High-Purity Bioactive Extract for Pharmaceutical R&D and Advanced Formulations
La camptotecina (CPT) è un naturally occurring alkaloid originally isolated from Camptotheca acuminata. Today, it remains a critical precursor for the synthesis of topoisomerase-I inhibitor drugs such as irinotecan E topotecan, widely researched in oncology and cellular biology.
A AIHerba® (Shaanxi Zhonghong Investment Technology Co., Ltd.), we manufacture high-purity camptothecin Sotto GMP-aligned standards, serving pharmaceutical companies, research institutes, nutraceutical developers, and biotechnology innovators.

2. Key Benefits & Functional Properties
Expert Review – Dr. L. Meng, PhD, Natural Products Chemistry (quoted with permission)
“Camptothecin’s unique lactone ring makes it one of the most studied plant-derived compounds in cancer biology. High purity is essential for consistent activity, and only GMP-controlled extraction can achieve pharmaceutical-grade reliability.”
Proprietà principali
-
Topoisomerase-I Inhibition
Widely used as a reference compound in oncology research (NIH, PubMed: PMID 2684270). -
Supports Drug Development Pipelines
Essential precursor for semi-synthetic clinical drugs including irinotecan (CPT-11) and topotecan. -
Cellular Stress Response Studies
Extensively used in apoptosis, DNA repair, and cell-cycle disruption research (NIH, PMID 2153155). -
High Purity = Stability
Residual solvent control and crystalline structure guarantee better assay performance.
3. Health-Related Research Insights
While Camptothecin is not a dietary supplement, it is one of the most influential natural products in anti-tumor drug discovery.
Research suggests potential roles in:
-
DNA replication interference
-
Anti-proliferative activity
-
In vitro anti-tumor mechanism modeling
-
Precision oncology tool compound applications
(References linked below.)
4. Traditional Botanical Background
Camptotheca acuminata has been referenced in traditional Chinese medicine literature as far back as the 17th century, used historically for “heat-clearing” and detoxifying functions—long before scientists isolated camptothecin in 1966.
5. Recommended Usage (For Industrial & Research Applications Only)
-
Ricerca e sviluppo farmaceutico: 95–98% HPLC
-
Reference Standard: 98%
-
Formulation Input: For precursor synthesis only
-
Cosmetic R&D: Typically micro-dosed in high-tech anti-aging prototypes (not consumer-facing due to regulations)

6. Best Formulation Guidelines
-
Solubilità: Poor water solubility; dissolve in DMSO, ethanol, or formulated carriers
-
Stabilità: Protect lactone ring—avoid high pH
-
Compatibilità: Sensitive to oxidation
-
Ideal Use: Oncology model systems, biosimilar pathway research, early-stage drug formulation
