| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

DNA-binding affinities and sequence specificities of protoberberine alkaloids and their demethylated derivatives: a comparative study.[Pubmed:17311227]
Chem Biodivers. 2007 Feb;4(2):145-53.
Berberrubine (1a), jatrorubine (2a), and Palmatrubine (3a) have been chemically prepared by partial demethylation of berberine (1), jatrorrhizine (2), and palmatine (3), respectively. Their interactions with calf thymus (CT) DNA, poly(dA-dT)poly(dA-dT), poly(dG-dC)poly(dG-dC), and eight AT-rich 12-mer double-stranded DNAs have been investigated by means of competitive ethidium bromide (EB) displacement experiments. The results showed that DNA-binding affinities of these protoberberine alkaloids have been significantly improved by partial demethylation, and that all of these alkaloids have the preferable binding affinities with AT-rich DNA. Especially, the sequence specificities of DNA-binding of demethylated derivatives 1a, 2a, and 3a had changed to a certain extent when compared with the parent alkaloids 1, 2, and 3, respectively. The binding mode of these alkaloids was further confirmed by UV spectroscopic titration experiments. All the compounds bind to double-stranded DNA most probably via an intercalating mode.
