PPARγmodulator-2 (Compound (R)-2n) is a reversible modulator of PPARγ, inhibiting the PPARγ ligand-binding domain (LBD) with an IC50 of 41 nM. It helps lower blood glucose levels, improves glucose tolerance and insulin sensitivity, and demonstrates antidiabetic activity in db/db mouse models.

LXRα agonist 1 (Compound 40) is a selective activator of LXRα, with an EC50 of 42 nM, and also demonstrates some activation effects on LXRβ, with an EC50 of 266 nM. It promotes target gene transcription by stabilizing the ligand-binding domain (LBD) of LXRα. When combined with the Raf inhibitor Sorafenib, LXRα agonist 1 shows significant antitumor activity in liver cancer cells. This compound is applicable in research focused on lipotoxicity-related cancers.

(+)-JJ-450 is a non-competitive antagonist that targets the androgen receptor (AR), inhibiting nuclear localization and transcriptional activity of AR under androgen-deprived conditions. In LN95 cells, (+)-JJ-450 is less effective than (-)-JJ-450 at inhibiting prostate-specific antigen (PSA) expression, likely due to its targeting of the AR ligand-binding domain (LBD). The compound works by promoting degradation of unbound AR within the nucleus and reducing AR binding to androgen response elements (AREs), thus inhibiting the transcriptional activity of AR and its splicing variants like ARv7. Additionally, (+)-JJ-450 is applicable for research in castration-resistant prostate cancer (CRPC) that is resistant to Enzalutamide (MDV3100).

JJ-450 is a non-competitive antagonist that targets androgen receptors (AR), capable of inhibiting the transcriptional activity of both wild-type AR and mutant ARF876L. It demonstrates an IC50 of approximately 1-10 μM for suppressing AR transcriptional activity in PC3 cells and selectively binds to AR without competing for the ligand binding domain (LBD) with androgens. JJ-450 functions by inhibiting the nuclear translocation of AR and promoting the degradation of unbound ligand AR within the nucleus, thereby suppressing the transcriptional activity of AR and its splice variants, such as ARF876L. This compound can be utilized in studies of castration-resistant prostate cancer (CRPC) that are resistant to Enzalutamide (MDV3100).

(-)-JJ-450 is a non-competitive antagonist targeting the androgen receptor (AR). It is more effective than (+)-JJ-450 in inhibiting androgen-induced AR activity, while (+)-JJ-450 inhibits AR via a mechanism distinct from Enzalutamide (MDV3100), possibly targeting the ligand-binding domain (LBD) of AR. (-)-JJ-450 inhibits transcriptional activity of both wild-type AR and the mutant ARF876L by suppressing AR nuclear translocation and promoting intranuclear degradation of unbound AR. This compound can be utilized in research focusing on castration-resistant prostate cancer (CRPC) that is resistant to Enzalutamide.

Amodiaquine dihydrochloride (Amodiaquin dihydrochloride), a member of the 4-aminoquinoline class, is an antimalarial agent that also acts as a potent oral histamine N-methyltransferase inhibitor with a K i value of 18.6 nM. Additionally, it functions as a Nurr1 agonist, targeting the Nurr1-LBD (ligand binding domain) with an EC 50 of approximately 20 μM, demonstrating anti-inflammatory effects [1] [2] [3] [4] [5].

GNE-274, a non-degrader compound structurally similar to GDC-0927 (an ER degrader), serves as a partial ER agonist in breast cancer cell lines without triggering ER turnover. Notably, GNE-274 enhances chromatin accessibility at ER-DNA binding sites, unlike GDC-0927. Acting as a potent inhibitor of the ER-ligand binding domain (LBD), GNE-274 exhibits potential for cancer research purposes.

Leriglitazone (Hydroxypioglitazone) hydrochloride, a pioglitazone metabolite, acts as a PPARγ agonist, effectively stabilizing the PPARγ activation function-2 (AF-2) co-activator binding surface to enhance co-activator binding, which results in a modest improvement in transcriptional efficacy. It binds to the PPARγ C-terminal ligand-binding domain (LBD) with a dissociation constant (K i) of 1.2 μM and demonstrates transcriptional efficacy with an effective concentration (EC 50) of 680 nM [1].

SR 19881 is a full agonist of ERRγ(EC50 value of 0.39 μM in a binding assay and an EC50 value of 4.7 μM in a cell-based assay).

Amodiaquine is a synthetic aminoquinoline, used to treat malaria.

The compound 4A7C-301-Nurr1 agonist is a specific agonist for the nuclear receptor-related 1 (Nurr1). By binding to the Nurr1 ligand-binding domain with an IC50 value of 48.22 nM, it enhances the transcriptional activity of both Nurr1-LBD and the full-length Nurr1, as demonstrated in reporter assays using SK-N-BE(2)C human neuroblastoma cells, with EC50 values of 6.53 and 50-70 µM, respectively. Additionally, administration of 4A7C-301-Nurr1 agonist at a dosage of 5 mg/kg per day has been shown to mitigate dopaminergic cell death in the striatum and substantia nigra pars compacta and ameliorate motor and olfactory deficits in mouse models of Parkinson's disease, circumventing the induction of dyskinesia-like behaviors. These models were induced either by the neurotoxin MPTP or by overexpression of α-synuclein.

JMV6944 is a PXR agonist that competitively inhibits the binding of ligands to the ligand-binding domain (LBD) of human PXR, with an IC50 value of 680 nM. Additionally, JMV6944 induces the expression of CYP3A4 mRNA in cultures of freshly isolated primary human hepatocytes.
