It has been demonstrated that epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) are efficacious in patients with EGFR mutation-positive non-small cell lung cancer (NSCLC). In this work, a new series of 2,4-diaryl pyrimidine derivatives containing cyclopropyl moiety were designed, synthesized and evaluated as novel selective EGFRL858R/T790M inhibitors. The most promising compound, 8l demonstrated excellent kinase inhibitory activity against EGFR double mutation with IC50 value of 0.26 nM. Moreover, 8l provided strong activity against H1975 cells with IC50 value of 0.008 μM and exhibited little toxicity toward four non-tumorigenic cell lines. Furthermore, 8l showed potent anti-tumor efficacy in a murine EGFRL858R/T790M-driven H1975 xenograft model. These results indicated that 8l may be a promising drug candidate for further study. There has been no report regarding the impact on male sexual life or sexual function by changes in lifestyle during the coronavirus disease 2019 (COVID-19) epidemic. To investigate the changes in sexual life and sexual function of Chinese men during the COVID-19 epidemic. An online questionnaire was created and the survey was administered through social media to Chinese adult men. The main end point was the deteriorated erectile function or ejaculatory control ability, defined by self-evaluation or by decreased International Index of Erectile Function-5 items (IIEF-5) scores or increased premature ejaculation diagnostic tool (PEDT) scores. Altogether, 612 questionnaires were collected. About 322 (52.6%) subjects were unmarried. About 8.4% and 8.5% subjects reported deteriorated erectile function or ejaculation control ability by self-evaluation, whereas 31.9% and 17.9% subjects showed decreased IIEF-5 scores or increased PEDT scores. Subjects with deteriorated erectile function by self-evaluation aneased frequency of sex
