With regard to identifying the effective components of LMWH drugs curing hepatic
fibrosis disease, we carried out a comparative study on the efficacy of
enzymatically depolymerized LMWHs on CCl(4) induced mouse liver fibrosis. The
results showed that the controlled enzymatic depolymerization conditions resulted
in LMWHs with significantly different activities. The LMWH product depolymerized
by Heparinase I (I-11) with a Mw of 7160, exhibited a significant advantage in
reducing the liver inflammation by suppressing TNF-? and IL-1? secretion, and
minimizing hepatic fibrogenesis. The products prepared by only Heparinase II
(II-11), and combined Heparinase III and II (III-II-5) showed limited positive
effect on hepatic inflammation and fibrosis. On the contrary, the products by
combined Heparinase III and I (III-I-9, III-I-5) showed no effect or stimulation
effect on the hepatic fibrogenesis. Our results provided the basis for
structure-activity relationship insight for inhibition of liver fibrosis
activities of LMWHs, which might have significant implications for generic
anti-fibrosis disease drug development.
