0 nm (CellTiter-Blue assay) and at 660 nm (methylene blue assay). Doxorubicin (Adriamycin) and imatinib (Gleevec) were utilized as optimistic controls for HUVEC, K-562, and HeLa cells. A repeat determination has been conducted in all experiments, and 4 replicates were assayed. The calculations with the distinctive values of GI50 and CC50 were performed with software program Magellan version 3.00 (Tecan Trading AG, Maennedorf, Switzerland). four. Conclusions The chemical investigation with the underground components of I. tenuifolia afforded inside the isolation of 5 unprecedented chromane derivatives (1, 9, ten) consists of an uncommon macrolide termed moniristenulide (1), together with seven recognized compounds (4, 112). Notably, eight out of nine isolated flavonoids possess a uncommon two ,three -disubstituted configuration on the B-ring, out of which the compounds bearing ortho-dihydroxyl groups in B-ring, namely three, 5, and ten, showed the broadest antimicrobial activity. On major of that, the molecules with methoxy or methylenedioxy substitution around the A-ring together with ortho-hydroxyl groups around the B-ring showed promising antiproliferative activities against leukemia cell lines in mixture with low cytotoxicity, as shown for compounds four and 10.Supplementary Components: The following are readily available on the web, Figures S1 10: 1D-, 2D-NMR, HRESI-MS, UV, CD, and HR-MS spectra of compound 1, Figures S11 17: 1D-, 2D-NMR, HR-ESI-MS, and UV spectra of compound two, Figures S18 25: 1D-, 2D-NMR, HR-ESI-MS, UV, and CD spectra of compound 3, Figures S26 32: 1D-, 2D-NMR, HR-ESI-MS, and UV spectra of compound 9, Figures S33 39: 1D-, 2D-NMR, HR-ESI-MS, and UV spectra of compound 10.Molecules 2021, 26,13 ofAuthor Contributions: W.B. and E.D. made the project and critically revised the manuscript.
