In Silico Investigation of Potential PARP‐1 Inhibitors from Traditional Chinese Medicine
Evidence-Based Complementary and Alternative Medicine, Volume 2014, Issue 1, 2014., 2014 Poly(ADP‐ribose) polymerases (PARPs) are nuclear enzymes which catalyze the poly‐ADP‐ribosylation involved in gene transcription, DNA damage repair, and cell‐death signaling. As PARP‐1 protein contains a DNA‐binding domain, which can bind to DNA strand breaks and repair the damaged DNA over a low basal level, the inhibitors of poly(ADP‐ribose ...

Evidence-Based Complementary and Alternative Medicine, Volume 2012, Issue 1, 2012., 2012 To identify effective herb to treat obesity, we screened 115 herbal extracts for inhibition of porcine pancreatic lipase (triacylg‐ycerol acylhydrolase, EC 3.1.1.3) activity in vitro. Of the extracts tested, Cudrania tricuspidata leaves exhibited the most pronounced inhibitory effect on lipase activity with an IC50 value of 9.91 μg/mL.
