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: 1.2 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: 1.4 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: 0.3 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: 0.00066 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: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

ABSTRACT

Breast cancer affects millions of women annually worldwide and is the leading cause of cancer death in women. Various bioactive phytochemicals based on natural products are considered to be an important source of chemopreventive agents. In this study we report−to our knowledge for the first time−9 phytochemicals isolated by nuclear magnetic resonance spectroscopy and mass spectrometry from the acetic ether extract of Pleurotus nebrodensis and identified as (1) ergosterol, (2) uracil, (3) ergosterol-3-O-β-D-glucopyranoside, (4) cerevisterol, (5) cerebroside B, (6) 5'-methylthioadenosine, (7) adenosine, (8) hypoxanthine, and (9) uridine. Their bioactivities were screened with an MTT assay using breast cancer MCF-7 cells in vitro. As a result, about half of the isolated compounds demonstrated moderate or strong inhibitory activity in a concentration-dependent manner. Among them, compound 1 (ergosterol) exhibited superior activity and the lowest half-maximal inhibitory concentration (112.65 μmol/L). Further mechanistic study elucidated that compound 1 led to significant S-phase cell cycle arrest and induced apoptosis in MCF-7 cells. Our study shows the mycochemical composition of the P. nebrodensis mushroom and provides guidance for use of compound 1 as a promising lead in cancer therapy.
