Metachromins X and Y from a marine sponge Spongia sp. and their effects on cell cycle progression

Bioorg Med Chem. 2020 Jan 15;28(2):115233. doi: 10.1016/j.bmc.2019.115233. Epub 2019 Nov 30.

Abstract

New sesquiterpene quinones, metachromins X (1) and Y (2), together with the known metachromins C (3), J (4), and T (5), were isolated as inhibitors of cell cycle progression in the HeLa/Fucci2 cells. The structure of 1 was assigned by spectroscopic data and confirmed by a total synthesis. The planar structure of 2 was determined by interpretation of spectroscopic data, whereas its absolute configuration was analyzed by a combination of chiral HPLC and CD spectroscopy. Metachromins X (1) and C (3) arrested the cell cycle progression of HeLa/Fucci2 cells at S/G2/M phase.
