A-935142 is a human ether-a-go-go-related gene (hERG, Kv 11.1) channel activator that enhances hERG currents by slowing inactivation, promoting activation, reducing inactivation, and shortening atrial and ventricular repolarization in a complex manner.

TCIP 1 is a small molecule in the category of transcriptional epigenetic covalent inhibitor probes (TCIPs) that forms covalent bonds with molecules targeting BCL6 and BRD4. This compound facilitates cell death gene expression by directing endogenous cancer drivers or transcription factors to the promoters of these genes. Additionally, TCIP 1 exhibits a gain-of-function mechanism, displaying both cell and tissue specificity, and it establishes a ternary complex with BCL6 and BRD4. It counteracts BCL6's inhibitory effect on apoptosis gene expression, leading to the activation of apoptosis. Furthermore, TCIP 1 markedly suppresses MYC oncogene expression and curtails the proliferation of diffuse large B-cell lymphoma (DLBCL) [1].

It is a potent, orally active CDK8 and CDK19 inhibitor (IC50s: 0.61 nM and 4.28 nM). STAT5 activation enhanced by AS2863619 free base inhibition of CDK8 19, which consequently activates the Foxp3 gene.

BHPI is a potent ERα inhibitor that blocks nuclear estrogen–ERα-regulated gene expression effectively. It triggers sustained ERα-dependent activation of the endoplasmic reticulum (EnR) stress sensor, notably the unfolded protein response (UPR), and consistently inhibits protein synthesis. With an IC50 value targeting ERα, BHPI's mechanism involves the rapid hyperactivation of PLCγ on the plasma membrane in ERα(+) cancer cells, which produces inositol 1,4,5-triphosphate (IP3). This, in turn, opens EnR IP3R calcium channels, leading to a rapid depletion of EnR Ca(2+) stores. SIGNIFICANTLY, BHPI alters estrogen-ERα's usual effect of causing mild and transient UPR activation by inducing a severe and prolonged UPR activation, transforming the UPR from a protective to a toxic response.

LAG-3biner 1 (compound 3) is a small molecule ligand for the immune checkpoint Lymphocyte Activation Gene 3 (LAG-3), with a dissociation constant (Kd) of 1.23 μM. It is used in research for targeting LAG-3 in cancer diagnostics.

Ingenol 3-monobenzoate (Ingenol 3-benzoate) acts as an aversive inducing agent. It binds to and activates protein kinase C (PKC) with a Ki of 0.14 nM. This activation inhibits the gene expression of phosphoenolpyruvate carboxykinase, thereby suppressing gluconeogenesis and increasing blood cortisol levels, which results in food aversion.

STING-IN-12 (compound Y2) acts as an inhibitor of STING. It suppresses IFNβ gene expression induced by SR717 with an IC50 of 0.75 μM. Additionally, STING-IN-12 inhibits STING pathway activation induced by the STING agonist SR717 in THP1 cells and by MSA-2 in mice.

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.

ACHP (IKK-2 Inhibitor VIII) is a novel selective and potent IKK inhibitor with inhibitory effects on IKK-α and IKK-β. ACHP has anti-HIV-1 activity and inhibits HIV-1 long terminal repeat (LTR)-driven gene expression through inhibition of NF-κB activation, inhibits TNF-α-induced NF-κB (p65) recruitment to the HIV-1 LTR, and inhibits TNF-α-induced NF-κB (p65) recruitment to the HIV-1 LTR. ACHKP has anti-HIV-1 activity and inhibits TNF-α-induced recruitment of NF-κB (p65) to the HIV-1 LTR.

Diflorasone is a synthetic glucocorticoid with anti-inflammatory and immunosuppressive properties. Like other glucocorticoids, diflorasone enters the cell by diffusion across the cell membrane and binds to the glucocorticoid receptor (GR) in the cytoplasm

SH-5, an AKT inhibitor potentiates apoptosis and inhibits invasion through the suppression of anti-apoptotic, proliferative and metastatic gene products regulated by IκBα kinase activation.

Smoothened (SMO) is a GPCR-like receptor which, with Patched, mediates hedgehog signaling to regulate gene expression through the Gli transcription factors. 20(S)-hydroxy Cholesterol (20(S)-OHC) is an oxysterol which binds SMO and activates hedgehog signaling (EC50 = 3 μM), and this activation is selective for the nat-20(S)-OHC enantiomer. Nat-20(S)-OHC synergizes with the SMO agonist SAG, suggesting an allosteric effect. Nat-20(S)-yne is a form of nat-20(S)-OHC with a terminal alkyne group, which can be used in linking reactions known as click chemistry. Click chemistry involves highly dependable and specific azide-alkyne bioconjugation reactions and can be used to capture or immobilize bioactive molecules. Thus, nat-20(S)-yne has been conjugated with magnetic beads to demonstrate that nat-20(S)-OHC directly binds SMO.

Pifithrin-β hydrobromide (Cyclic PFT-α) is an inhibitor of p53; reversibly blocks p53-dependent transcriptional activation and apoptosis. Protects against neuronal death in models of stroke and neurodegenerative disorders. Active in vivo; protects mice from the side-effects of Y therapy associated with p53 induction. Supresses self-renewal of embryonic stem cells. Also aryl hydrocarbon receptor (AHR) agonist, causes upregulation of AHR target gene CYP1A1 (EC50 = 1.1 μM).

Sesamol (1,3-Benzodioxol-5-ol) could decrease lung inflammation and lipopolysaccharide (LPS)-induced lung injury in rats. Sesamol ameliorates inflammatory and oxidative damage by upregulating AMPK activation and Nrf2 signaling and blocking the NF-κB and MAPK signaling pathways and inhibits melanin biosynthesis by down-regulating tyrosinase activity and melanin production via regulation of gene expression of melanogenesis-related proteins through modulation of MITF activity, which promotes phosphorylation of p38 and JNK in melan-a cells.

1. Prunetin (Prunusetin) significantly reduces serum levels of inflammatory cytokines and mortality in mice challenged with lipopolysaccharide. 2. Prunetin mediates anti-obesity adipogenesis effects by suppressing obesity-related transcription through a feedback mechanism that regulates the expression of adiponectin, adipoR1, adipoR2, and AMPK. 3. Prunetin and biochanin A are potent reducers of NF-κB and ERK activation, zonula occludens 1 tyrosine phosphorylation, and metalloproteinase-mediated shedding activity, which may account for the barrier-improving ability of these isoflavones. 4. Prunetin significantly suppresses ATP-induced mucin secretion from cultured RTSE cells; Prunetin inhibits the production of MUC5AC mucin protein induced by EGF or PMA from NCI-H292 cells; Prunetin also inhibits the expression of MUC5AC mucin gene induced by EGF or PMA from NCI-H292 cells.

Interferon alfa, a type I interferon, activates new genes, displaying strong antiviral and antiproliferative effects on target cells. It signals through receptor-mediated activation of Stat1 and Stat2, which heterodimerize into a STAT complex binding with the DNA-binding protein IRF-9 (p48) to form ISGF-3 (IFN-stimulated gene factor 3). This complex further activates driver genes to fulfill its antiviral role [1].
