Biological Activity

Coelenterazine (CTZ) can be catalyzed by luciferases, such as the sea pansy Renilla reniformis (Rluc) and the marine copepod Gaussia princeps (Gluc), which results in emission of blue light. In Gli36-Gluc- or Gli36-Rluc-expressing Gli36 cells, coelenterazine (8 μM/ml) shows a bioluminescence signal.

In vivo, in 4T1-implanted mouse, Coelenterazine detects cancer-associated superoxide anion and used to evaluate the role of superoxide anion in cancer cell biology and its role in pathology.

*The compound is unstable in solutions, freshly prepared is recommended

Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
