Aglycone flavones, flavopiridol, and atuveciclib, but not L7G, inhibit spontaneous provirus expression. (A) Representative flow cytometry plots showing GFP and viral p24Gag protein expression in J-Lat 10.6 cells following 15 days’ incubation in the absence or presence of 10 μM chrysin or L7G. (B) Effects of compounds on spontaneous provirus expression in J-Lat 10.6 cells over 21 days. (C) Effects of compounds on Jurkat cell viability, as measured using Viacount dye, over 21 days. For (B-C), results are presented relative to cells treated with 0.1% DMSO over the same time course (black dotted lines).
