The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

ABSTRACT

The biological activities and chemopreventive properties of green tea polyphenols have been demonstrated, while similar information regarding newly formed major polymeric polyphenols in black tea are not available. Cancer chemoprevention may be achieved by the inhibition of any stage of carcinogenesis. In the present study, we investigated the anti-initiating effects of five polymeric black tea polyphenol (PBP) fractions, by determining their effects on the formation of [3H]-B(a)P-derived DNA adducts as well as the activity of cytochrome P-450 isozymes CYP 1A1 and 1A2 in vitro employing rat liver microsomes. PBP 1-3 inhibited both the microsome catalyzed [3H]-B(a)P-derived DNA adduct formation as well as the activity of CYP 1A1 and 1A2 as assessed by the decreased formation of resorufin from the respective substrates. Further investigation revealed that topical pretreatment(s) of mice with PBP 1-5 (200 μg/day × 4) resulted in a significant decrease in the levels of single topical B(a)P (1 mg/mouse) - induced DNA adducts in epidermal DNA determined by employing 32P-post labeling analysis. Overall, our results suggest that black tea-derived PBPs have one of the chemopreventive properties shown by monomeric green tea polyphenols.
