0 nm (CellTiter-Blue assay) and at 660 nm (methylene blue assay). Doxorubicin (Adriamycin) and imatinib (Gleevec) have been utilised as positive controls for HUVEC, K-562, and HeLa cells. A repeat determination has been performed in all experiments, and 4 replicates were assayed. The calculations of the various values of GI50 and CC50 were performed with computer software Magellan version three.00 (Tecan Trading AG, Maennedorf, Switzerland). 4. Conclusions The chemical investigation from the underground parts of I. tenuifolia afforded in the isolation of 5 unprecedented chromane derivatives (1, 9, 10) contains an uncommon macrolide termed moniristenulide (1), together with seven known compounds (four, 112). Notably, eight out of nine isolated flavonoids possess a uncommon two ,three -disubstituted configuration around 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 top of that, the molecules with methoxy or methylenedioxy substitution on the A-ring with each other 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 ten.Supplementary Materials: The following are obtainable on-line, Figures S1 ten: 1D-, 2D-NMR, HRESI-MS, UV, CD, and HR-MS spectra of (��)-Indoxacarb Autophagy 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 three, 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. created the project and critically revised the manuscript.
