Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The partially purified catechin fraction isolated from green tea extract was treated with a variety of acylating agents (acyl anhydrides/chloride) to obtain (-)-epigallocatechin-3-gallate (EGCG) O-acyl derivatives in 20-25.4% yields. The (-)-EGCG O-acyl derivatives were characterized by physical data and spectral studies. These compounds were evaluated for their antitumor activity by use of a two-stage carcinogenesis model in 7,12-dimethylbenz[a]anthracene (DMBA)/12-O-tetradecanoylphorbol 13-acetate (TPA)-induced cancer in Swiss albino mice. The study showed that there was a significant decrease in the antitumor activity with the increase in size and branching of the chain length of acyl groups. The results indicated that these O-acyl derivatives of (-)-EGCG have the potential to be developed as cancer chemopreventive agents. © 2007 American Chemical Society.
