Berberine is an isoquinoline alkaloid contained in plants of Ranuculaceae and Berberidaceae. Extracts of berberine-containing plants have been used as Chi nese folk remedies for centuries. After screening the antihypertensive activit y in spontaneously hypertensive rats ( SHRs ), 6-protoberberine ( PTB-6 ) was found to be most effective in the synthetic compounds from berberine. In cons cious SHRs, PTB-6 lowered the systemic arterial blood pressure ( SBP ) in a do se-dependent manner. The possible mechanisms were then investigated in the pr esent study. Cardiac output in PTB-6-treated anesthetized SHRs, using thermodi lution method, was modified slightly with an decrease of heart rate. Also, th e total peripheral resistance was attenuated by PTB-6. In isolated aortic rin gs from normotensive rats, PTB-6 produced relaxation in a precontraction-depen dent manner in both the presence and absence of endothelium. Specific effect on a-adrenoceptor by PTB-6 was characterized using radioligand binding study. PTB-6 also can dose-dependently inhibit the effect of KCl-induced membrane dep olarization. Using fura-2 to study the calcium influx into vascular smooth mu scle cells, this work observed that high concentration of PTB-6 inhibited calc ium influx into vascular smooth muscle cells. Moreover, PTB-6 was found to in hibit left ventricular pressure in isolated rat heart. Another hand, injectio n of PTB-6 into the intracerebral ventricula of the brain ( i.c.v. ) can lower the systemic arterial blood pressure and heart rate of SHRs. The results indi cate that PTB-6 works more effective than other derivatives of berberine to lo wer the SBP in SHRs via an influence on cardiac output and vascular tone.

Berberine, a quaternary ammonium salt isoquinoline alkaloids. It has a wide range of biochemical and pharmacological effects. The objective of this study was to synthesize 13-O-lipophilic substituted berberine derivatives and evaluate their photocytotoxic effects against human colon cancer cell lines. The modified berberine at 13-O-position by n-alkyl lipophilic substitution was synthesized and in vitro investigated for cytotoxicity and photocytotoxicity by MTT assay. The introduction of lipophilic substituents at 13-O-position of the berberine scaffold led to potent inhibition against human colon cancer cells. Among 8 synthesized compounds, compound 4e exhibit strongest growth inhibition against human colon cancer cells. HPLC analysis showed that the lipophilic modification of 4e enhanced the cellular uptake in DLD-1 cells. Cell viability assay showed that 4e inhibited the cell growth of SW480, DLD-1 and HT-29 cells in a dose- and time-dependent manner and in a light dose- and time-dependent manner after visible light (420 nm) irradiation. Flow cytometry analysis was employed to evaluate the photocytotoxic effects of berberine (1) and 4e for cell cycle effect, cell death, intracellular reactive oxygen species (ROS) and mitochondrial membrane potential (ΔΨm) charge in DLD-1 cells. In cell cycle analysis, 4e induced remarkable SubG1 phase in DLD-1 cells after light irradiation. In cell death analysis, 4e induced cell both apoptosis and necrosis after light irradiation. Compound 4e also distinctly induced intracellular ROS and reduced mitochondrial membrane potential in DLD-1 cells after light irradiation. In conclusion, photodynamic treatment of 4e demonstrated a significant photocytotoxic effects in SW480, DLD-1 and HT-29 cells, induced remarkable cell apoptosis and necrosis, increased intracellular ROS level and triggered mitochondrial membrane potential depolarization. The conclusion revealed that berberine derivatives at 13-O-position bearing n-alkyl group had the potential as a candidate of anticancer agent and phototherapeutic drugs.
