Aplidine (20 nM; 1 h) induces a dose-dependent decrease in VEGF secretion in MOLT-4 cells.
Aplidine (20 nM; 1 h) does not result in significant inhibition of VEGF-R1 mRNA in normal endothelial cells, which do express VEGFR-1 but do not secrete VEGF.
Aplidine inhibits SARS-CoV-2 with an IC90 of 1.76 nM. In hACE2-293T cells, Aplidine exhibits anti–SARS-CoV-2 activity with an IC90 of 0.88 nM. In an established model of human pneumocyte-like cells, Aplidine inhibits SARS-CoV-2 replication with an IC90 of 3.14 nM and a selectivity index of 40.4.
