TASK-1-IN-1 is a potent and selective inhibitor of TASK-1 (Potassium Channel) with an IC50 of 148 nM, and exhibits a reduced inhibitory effect on the TASK-3 channel with an IC50 of 1750 nM. TASK-1-IN-1 also demonstrates anticancer effects.

ASK1-IN-4 is an ASK1 inhibitor, IC50 = 0.2 μM.

SK1-IN-1 is an orally available and potent sphingosine kinase 1 (SPHK1) inhibitor (IC50: 58 nM), with potential anticancer activity, and can be used to study cancer and neurodegenerative diseases.

ASK1-IN-7 (Compound 4c) is an ASK1 inhibitor and a derivative of the ASK1 inhibitor scaffold 5-(5-Phenyl-furan-2-ylmethylene)-2-thioxo-thiazolidin-4-one. This compound is potentially applicable in research involving ASK1 signaling pathways, including studies on cellular stress response, inflammatory response, neurodegenerative diseases, and cardiovascular diseases.

ASK1-IN-8 (Compound 35) is an orally active inhibitor of apoptosis signal-regulating kinase 1 (ASK1) with an IC50 value of 1.8 nM. In a mouse liver injury model induced by Acetaminophen, ASK1-IN-8 significantly reduces plasma alanine aminotransferase (ALT) levels, offering liver protection. This compound is useful for research in liver disease-related fields.

SK1-I hydrochloride is the salt form of SK1-I(BML-258). SK1-I is a selective and competitive sphingosine kinase 1 (SphK1) inhibitor and sphingosine analog that is inactive against SphK2 and a variety of other protein kinases, and possesses anti-leukemic potential to inhibit tumor cell growth and promote apoptosis.

ASK1-IN-3 is a highly potent and selective inhibitor of ASK1 kinase, demonstrating an IC 50 of 33.8 nM. This compound also exhibits inhibitory effects on various cell cycle regulating kinases. ASK1-IN-3 showcases remarkable induction of apoptosis in HepG2 cancer cells and displays potent activity in arresting the cell cycle [1].

ASK1-IN-6 (Compound 32), a selective apoptosis signal-regulating kinase 1 (ASK1) inhibitor, exhibits an IC50 of 25 nM. This compound readily crosses the blood-brain barrier, as evidenced by rat pharmacokinetics showing a clearance/unchanged clearance rate of 1.6/56 L/h/kg and an unbound partition coefficient (Kp,uu) of 0.46. Additionally, ASK1-IN-6 demonstrates anti-inflammatory activity and effectively improves symptoms in the Alzheimer's Disease Tg4510 mouse model.

ASK1-IN-2 is a potent, orally active inhibitor of apoptosis signal-regulating kinase 1 (ASK1), with an IC50 of 32.8 nM. It has potential therapeutic applications for ulcerative colitis[1].

ASK1-IN-1 is an inhibitor of apoptosis signal-regulating kinase 1 which is a key mediator in the apoptotic and inflammatory cellular stress response with an IC50 of 21 nM in biochemica assays.

Scyllatoxin (Leiurotoxin I), a peptide toxin derived from the venom of the scorpion (Leiurus quinquestriatus hebraeus), acts as a blocker of small-conductance K Ca (SK) channels. It notably enhances the release of norepinephrine (NE) and epinephrine (Epi) in vivo [1].

Dendrogenin A (DDA) is a compound acting as a selective liver X receptor (LXR) modulator, cholesterol epoxide hydrolase inhibitor (Ki = 120 nM), and a metabolic product of cholesterol, originating from 5,6α-epoxy cholesterol through histamine conjugation via DDA synthase. This compound is present in non-cancerous human mammary epithelial cells and melanocytes, but absent or minimally present in various breast carcinoma, melanoma cells, and isolated human breast tumor tissues. DDA impedes the activation of LXRβ and LXRα induced by 22(R)-hydroxy cholesterol (IC50s = 76 and 362 nM, respectively), yet it also functions as a partial LXR agonist, boosting the protein levels of Nur77, NOR-1, LC3-I, and LC3-II in B16/F10 murine melanoma cells. It shows a preference for LXRα and LXRβ modulation while displaying selectivity over other receptors including pregnane X receptor (PXR), and various others at a concentration of 2.5 µM. Moreover, DDA enhances LC3-II protein levels in cancer cells and prompts autophagic cell death at specific concentrations. Notably, DDA (0.37 µg/kg) has been shown to diminish tumor growth in melanoma and mammary cancer murine models and promotes cancer cell differentiation both in vitro and in vivo.
