Human Endogenous Metabolite

In Vitro 5-ALA benzyl ester hydrochloride (Benzyl-ALA hydrochloride) (0.6-0.12 mM; 3 h) induces protoporphyrin IX (PPIX) accumulation in colon carcinoma cell lines SW480[2].
In Vivo Reducing the dose of 5-ALA benzyl ester hydrochloride (31 mg/kg; i.v. ; 1 hours) results in a dose-dependent reduction in tumour porphyrin levels[3]. Animal Model: Female CBA/Gy mouse (CaNT tumour model)[3] Dosage: 31 mg/kg Administration: i.v. ; 1 hours Result: Reducing the dose of 5-ALA benzyl ester hydrochloride resulted in a dose-dependent reduction in the concentration of porphyrins accumulating in the CaNT tumour.
