Prednicarbate exhibits a diverse range of bioactivities. Notably, it demonstrates a high potency in inhibiting Chronic Active B-Cell Receptor Signaling with a value of 5.2 nM and shows a potency of 58.0 nM in the Nrf2 screening assay, which is confirmed in the Nrf2 A549 ARE-Fluc Confirmation Assay for Hit Validation. Additionally, it inhibits the AmpC Beta-Lactamase enzyme with a potency of 79,432.8 nM in the presence of a detergent and HP1-beta Chromodomain interactions with methylated histone tails at 100,000.0 nM. Prednicarbate also acts as an inhibitor in the primary qHTS for delayed death of the malarial parasite plastid with a potency of 18,526.0 nM and inhibits human tyrosyl-DNA phosphodiesterase 1 (TDP1) in cells both without and with CPT present, showing potencies of 16,066.6 nM and 12,762.2 nM, respectively.
The compound has a bioactivity profile suggesting a low risk of drug-induced liver injury, with all measured Hepatic Side Effect (HepSE) scores in the DILIps training set reported as 0.0. This includes scores for bilirubinemia, cholecystitis, cirrhosis, hepatitis, and abnormal liver function tests among others, along with a combined HepSE score of 0.0, highlighting its low potential for hepatic side effects.
In antiviral assays, Prednicarbate shows bioactivity in inhibiting cell viability in Vero E6 cells infected with SARS-CoV-2 (strain BavPat1) with an inhibition index of 1.368, indicating higher activity than the arbidol control. However, its IC50 value in the inhibition of SARS-CoV-2 induced cytotoxicity of VERO-6 cells is greater than 20,000.0 nM, pointing to relatively low potency in this context.
Additionally, Prednicarbate has high binding affinity (> 10,000.0 nM) towards various receptors such as human ADRB1, ADRB2, SLC6A3, OPRK1, ADORA1, ADRA1A, and others. It shows agonist activity at human OPRM1, HRH2, DRD1, PGR, HTR2A, and antagonist activity at CHRM2, HTR1A, ADRA2A, HTR2A, and HTR2B. It has a significant affinity for the human NR1I2 receptor with an AC50 value of 17.0 nM..
