The growth thermogenic curves of Escherichia coli (E. coli) affected by berberine, coptisine and palmatine were determined quantitatively by microcalorimetry. The power-time curves of E. coli with and without the three berberines alkaloids (BA) were acquired, meanwhile the extent and duration of inhibitory effects on the metabolism were evaluated by growth rate constant (k), half- inhibitory ratio (IC50), peak time of maximum heat-output power (tp), total heat-production (Qt) and so on. The inhibitory effects of BA on E. coli revealed that the sequence of their antimicrobial activity was berberine > coptisine > palmatine. The functional groups methylenedioxy at C2 and C3 on phenyl ring improve antimicrobial activity more remarkably than methoxyl at C2 and C3 on phenyl ring. However, the antimicrobial activity does not vary significantly with methylenedioxy or methoxyl at C9 and C10 on phenyl ring.

Coptis Chinensis is a traditional Chinese medicine herb that has the effect of clearing heat and drying dampness, purging fire to eliminate toxin. Berberine is the main alkaloid of Coptis Chinensis, and, recent researches showed that berberine had the effect of anti-atherosclerosis. This paper reviewed the anti-atherosclerosis mechanism of berberine, which may be related to regulating lipids, anti-inflammation, decompression, reducing blood sugar, and inhibiting vascular smooth muscle cell proliferation.

The effects of Coptis chinensis on the behavior of squamous cell carcinoma have not yet been established. We examined the anticancer activity of Coptis chinensis on human squamous carcinoma cells, both in vitro and in xenografted nude mice, and applied Pathway Array Technology to understand possible involvement of signaling pathways in Coptis Chinensis induced tumor cells inhibition as well. Following Coptis chinensis treatment, a time-dependent reduction in proliferation was observed in both cell lines and NCR/NU mice. Coptis chinensis has a wide effect on cell signaling, including cell cycle regulation (Cdk6, Cdk4, cyclin B1, cyclin E, cyclin D1, p27), cell adhesion (E-cadherin, osteopontin), differentiation, apoptosis(p-Stat3, p53, BRCA1), cytoskeleton (p-PKC α/β II, Vimentin, p-PKCα), MAPK signaling (raf-1, ERK1/2, p-p38, p-ERK), and the phosphatidylinositol 3-kinase signaling pathway (p-Akt, Akt, p-PTEN). In our conclusions, Coptis chinensis may be a novel therapeutic drug for squamous cell carcinoma.
