Radioactive synthesis and biodistribution study of β-elemene- 99mTc(CO)3 conjugates
β-Elemene, (5S,7R,10S)-(−)-(1-methyl-1-vinyl-2,4-diisopropenylcyclohexane), is an anticancer agent from traditional Chinese herbal medicine. Three novel 99mTc(CO)3-β-elemene conjugates were synthesized successfully, and compared with β-elemene exhibited improved water solubility. A biodistribution and micro single photon emission computed tomography image study showed there is a visible accumulation in Lewis lung cancer tumors.
