PRE-084 hydrochloride has been extensively tested for its bioactivities and has demonstrated a wide-ranging spectrum of effects. It shows potency in inhibiting the proliferation of various Plasmodium falciparum lines, with IC50 values ranging from 4466.8 nM to 14125.4 nM. Additionally, PRE-084 hydrochloride exhibits activity against endonuclease IV, the Menin-MLL interaction in leukemias, lipid storage modulation, histone lysine methyltransferase G9a, and delayed death inhibitors of the malarial parasite. It also affects HP1-beta chromodomain interactions with methylated histone tails, the human hERG channel, Marburg virus entry, Hepatitis C virus, and human tyrosyl-DNA phosphodiesterase 1 (TDP1), and induces synthetic lethality in 2HG-producing tumor cells.
PRE-084 hydrochloride acts as an agonist at the sigma1 receptor in rat PC12 cells, enhancing NGF-induced neurite outgrowth by 27.5% and increasing neurite length by 181.3 um at 10 μM concentration over 5 days. This agonist activity persists in the presence of a sigma1 receptor antagonist BD-1063, albeit with reduced effectiveness, showing a decrease in neurite outgrowth by 16.0% and neurite length by 140.1 um. Similar trends are observed with another antagonist BD-1064, showing a decrease in neurite length by 23.0%.
The compound exhibits high affinity for the sigma1 receptor with Ki values of 58.7 nM and 66.6 nM in the presence of DPH, but has significantly lower affinity (150.8 nM) in the DPH solvent. It shows minimal binding to kappa and delta opioid receptors, indicating selectivity towards sigma1 receptors under these assay conditions.
Additionally, PRE-084 hydrochloride exhibits antiviral properties; it inhibits SARS-CoV-2 induced cytotoxicity in Caco-2 and VERO-6 cells, with inhibition rates of 17.53% and 1.21%, respectively, after 48 hours at 10 μM concentration, determined through high content imaging. Furthermore, it inhibits the SARS-CoV-2 3CL-Pro protease by 13.0% at a concentration of 20 µM as measured by a FRET-based assay..
