DAPT (LY-374973) is a γ-secretase inhibitor that inhibits total Aβ and Aβ42 (IC50=115/200 nM) and is orally active. DAPT is also a Notch inhibitor. DAPT induces cell differentiation, autophagy and apoptosis.

Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that suppresses HDAC1 activity and induces HDAC2 degradation, exhibiting oral bioavailability. Valproic Acid activates Notch1 signalling and inhibits the proliferation of small cell lung carcinoma cells, making it applicable for research into epilepsy and bipolar disorder.

Jagged-1 (188-204) TFA(219127-21-6 free base) is a fragment of the JAG-1 protein. JAG-1 is Notch ligand, a peptide that is the most conspicuously expressed ligand in skin. JAG-1 induces epidermal maturation. Exposing submerged keratinocytes monolayers to JAG-1 with elevated calcium concentration produces stratification with loricrin expression and NF-alphaB activation.

BMS-906024 (Osugacestat) is an orally available and selective inhibitor of γ-secretase, a small molecule Notch inhibitor.BMS-906024 has broad-spectrum antitumour activity against a variety of human cancer xenografts.BMS-906024 prevents the activation of all four Notch receptors, and is active against Notch1, -2, -3 and -4 receptors. BMS-906024 prevents the activation of all four Notch receptors, with IC50s of 1.6, 0.7, 3.4 and 2.9 nM for Notch1, -2, -3 and -4 receptors, respectively.

Gossypolone is is a proposed major metabolite of gossypol. Gossypolone reduces Notch/Wnt signaling and induces apoptosis.

YO-01027 (DBZ) is a potent γ-secretase inhibitor.

CB-103 is a orally active inhibitor of notch signaling pathway, with anti-tumor activity.

Valproic acid sodium salt (Sodium Valproate) is the sodium salt form of valproic acid with anti-epileptic activity. Valproic acid sodium salt is converted into its active form, valproate ion, in blood. Although the mechanism of action remains to be elucidated, Valproic acid sodium salt increases concentrations of gamma-aminobutyric acid (GABA) in the brain, probably due to inhibition of the enzymes responsible for the catabolism of GABA. This potentiates the synaptic actions of GABA. Valproic acid sodium salt may also affect potassium channels, thereby creating a direct membrane-stabilizing effect.

Tangeretin (NSC-618905), a flavonoid from citrus fruit peels, has been proven to play an important role in anti-inflammatory responses and neuroprotective effects in several disease models and was also selected as a Notch-1 inhibitor.

1. Carvacrol (O-Thymol) presents anxiolytic effects. 2. 5-Isopropyl-2-methylphenol presents antinociceptive activity. 3. Carvacrol presents antidepressant effects, seems to be dependent on its interaction with the dopaminergic system, but not with the serotonergic and noradrenergic systems.

Divalproex Sodium (Valproate semisodium) binds to and inhibits gamma-aminobutyric acid (GABA) transaminase and its anticonvulsant activity may be exerted by increasing brain concentration of GABA and by inhibiting enzymes that catabolize GABA or block the reuptake of GABA into glia and nerve endings. It also is an HDAC inhibitor, Comprised of sodium valproate and valproic acid with anticonvulsant and antiepileptic activities. Divalproex may also work by suppressing repetitive neuronal firing through the inhibition of voltage-sensitive sodium channels.

Avagacestat (BMS-708163) (BMS-708163) is a potent, selective, orally bioavailable γ-secretase inhibitor of Aβ40 and Aβ42 with IC50 of 0.3 nM and 0.27 nM, demonstrating a 193-fold selectivity against Notch. Phase 2.

JI051 is an antitumor agent that interacts with the cancer-associated protein chaperone prohibitin 2 (PHB2) to induce cell cycle arrest by inhibiting the transcription of the Notch downstream effector gene, Hes1, and inhibits the proliferation of HEK293 cells and pancreatic cancer cells.

ZLDI-8 is an inhibitor of Notch activating/cleaving enzyme ADAM-17 and inhibits the cleavage of Notch protein.

BMS-983970 is an oral inhibitor of pan-Notch, and for the treatment of multiplecancers.

FLI-06 is a Notch signaling inhibitor (EC50: 2.3 μM).
