Synthesis and in vitro glucose-lowering effect of 8-alkyl-coptisine / 中草药

ABSTRACT

Objective: To investigate the effect of 8-alkyl-coptisine on glycometabolism in vitro. Methods: HepG2 cells similar to human hepatic cells were used to test the glucose consumption (GC) in cultural solution in 24 h and MTT assay was used to monitor the proliferation of HepG2 cells. Results: The results indicated that 8-alkyl-coptisine could increase the amounts of GC of HepG2 cells. In glucose concentration (10 mmol/L), 8-hexyl-coptisine was the most significant. 8-Alkyl-coptisine had notable inhibition in proliferation of HepG2 cells. Conclusion: 8-Alkyl-coptisine was successfully synthesized. GC could increase as the length of the aliphatic chain increases firstly and the GC could decrease when the length of the aliphatic chain exceeds six atoms. 8-Hexyl-coptisine is a potential hypoglycemic leading compound.
