Background

(+)-Catechin (Cianidanol, Catechinic acid, Catechuic acid) is an antioxidant flavonoid, occurring especially in woody plants as both (+)-catechin and (-)-epicatechin (cis) forms.


The catechin flavonoid reduces proliferation and induces apoptosis of murine lymphoma cells LB02 through modulation of antiapoptotic proteins[1]. Treatment of human prostate cancer cells with catechin induces apoptosis and results in effects on a variety of survival signals suggesting the potential of these compounds as chemopreventive agents for prostate cancer[2]. Catechin is well known to inhibit cyclooxygenase activity with reported IC50 values ranging from 4O μM to 943 μM. It has also been reported to act as an inhibitor of COX-1 and COX-2 with IC50 of about 80 ?M and 130 μM[3].


Dietary catechin significantly delayed tumor onset[5]. Continued intake of catechin, a potential antioxidant, prevents memory regression and DNA oxidative damage in senescence-accelerated (SAMP10) mice. It does not prolong the lifetime of SAMP10 mice, but it does delay brain senescence[6]. (+)-Catechin inhibits intestinal tumor formation and suppresses Focal adhesion kinase activation in the Min/+ Mouse[7].

Protocol

Cell experiment:

The Cell viability assay is performed to assess the toxicity of different concentrations of Catechin on MCF-7 cells. Briefly, MCF-7 cells (2×104 cells/well) are plated in 96-well plates and treated with 0 μg/mL Catechin and 160 μg/mL Catechin for 24 hours. Then, 40 μL of the Cell Titer Blue solution is directly added to the wells and incubated at 37°C for 6 hours. The fluorescence is recorded with a 560 nm/590 nm (excitation/emission) filter set using a microplate fluorescence reader, and the IC50 is calculated. Quadruplet samples are run for each concentration of Catechin in three independent experiments[2].

Animal experiment:

Rats[3]Twelve weeks old, healthy male rats weighing 200 to 230 g are used in this study. Rats are divided into four experimental groups (n=9 each) for one vehicle and three groups of Catechin (three doses). The doses of Catechin are prepared at 50, 100, 200 mg/kg in 0.25% w/v sodium carboxy methylcellulose (CMC) and administered orally for 7 days prior to and during the experimental trials. Episodic memory, the conscious memory of the past experiences is evaluated in this study[3].
