COX-1:1.4 μM (IC50)

In Vitro Catechin exhibits >95% inhibitory activity at 70 μg/mL against cyclooxygenase-1 (COX-1) with an IC50 of 1.4 μM[1]. A dose-dependent reduction in color is observed after 24 hours of treatment with Catechin, and 54.76% of the cells are dead at the highest concentration of Catechin tested (160 μg/mL) whereas the IC50 of Catechin is achieved at 127.62 μg/mL Catechin. A dose- and time-dependent increase in the induction of apoptosis is observed when MCF-7 cells are treated with Catechin. When compare to the control cells at 24 hours, 40.7 and 41.16% of the cells treated with 150 μg/mL and 300 μg/mL Catechin, respectively, undergo apoptosis. The expression levels of Caspase-3, -8, and -9 and p53 in MCF-7 cells treated with 150 μg/mL Catechin for 24 h increase by 5.81, 1.42, 3.29, and 2.68 fold, respectively, as compare to the levels in untreated control cells[2].
In Vivo Animals treated with Catechin at the lowest tested dose, i.e., 50 mg/kg, p.o. have spent comparatively more time in exploring the novel object in the choice trial, however, the difference is not statistically significant. Catechin prevents the time-induced episodic memory deficits in a dose-dependent manner, the most effective being 200 mg/kg, p.o.. Treatment with Catechin prevents the rise in MPO level compare to DOX alone treatment group (21.98±9.44 and 36.76±4.39% in the hippocampus and the frontal cortex respectively)[3].
Cell Assay 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 Admin 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].
