Synthesis and Physiological Activity of Novel Berberine Derivatives
TO synthesize novel berberine derivatives with a variety of physiological activities
and study their antitumor activity and acetylcholinesterase inhibitory activity.
Method:
2
Berberines with a variety of physiological activities were pieced together isohydroxamic acid
o
-phenylenediamine
and sulfhydryl pharmacophore with effects in inhibiting histones and removing acetylases. Totally 7 novel berberine derivatives were obtained by means of organic synthesis. The structures of these derivatives were characterized and confirmed by
1
H-NMR
13
C-NMR and MS spectral data.Thiazolyl blue tetrazolium bromide(MTT) method was used in the determination of the cytotoxic activity of HCT116
HepG2
HeLa and CCRF-CEM human cancer cell lines
in vitro
.
Ellman
method was used to reveal the inhibitory activities of acetylcholinesterase and butyrylcholinesterase.
Result:
2
The results showed that the berberine derivatives containing methyl ketone had good antitumor and acetylcholinesterase inhibitory activities. The results demonstrated that compound 5bhad the highest anti-proliferative activity against CCRF-CEM cell line and the acetylcholinesterase inhibitory activities
with IC
50
=1.48 μmol·L
-1
and IC
50
=0.38 μmol·L
-1
respectivly.
Conclusion:
2
This paper provides a reference for the synthesis and biological evaluation of this kind of alkaloid derivatives. Compound 5bis a promising candidate drug and worth further study.
