irinotecan/dichloromethane

A new, simple, sensitive and specific reversed-phase high performance liquid chromatographic (HPLC) method using ultraviolet detection was developed and validated for the analysis of CPT-11 (lambda(max)=254 nm, 365 nm) and its major active metabolite, SN-38 (lambda(max)=380 nm) in rat plasma and

Although irinotecan is an important anticancer drug for treating colorectal cancer, its dose-dependent side effects limited its clinical application. Thus, it's important to develop low-toxic candidates to enhance the efficacy of irinotecan. Polyynes from genus Oplopanax were reported to possess

SN-38 (7-ethyl-10-hydroxycamptothecin) is the active metabolite of irinotecan (CPT-11), which is 100-1000-fold more cytotoxic than irinotecan. Nonetheless, the extreme hydrophobicity of SN-38 has prevented its clinical use. SN-38 is poorly soluble in aqueous solutions, and it is practically
