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.

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.

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.

Psoralidin inhibits Akt phosphorylation and phosphatidylinositol 3-kinase activation and transcriptionally. Psoralidin possesses anticancer and chemopreventive properties.

MRK003 is a γ-secretase inhibitor exhibits promising in vitro pre-clinical activity in multiple myeloma and non-Hodgkin's lymphoma. MRK003 treatment induced caspase-dependent apoptosis and inhibited proliferation of MM and NHL cell lines and patient cells. Examination of signaling events after treatment showed time-dependent decrease in levels of the notch intracellular domain, Hes1 and c-Myc. MRK003 downregulated cyclin D1, Bcl-Xl and Xiap levels in NHL cells and p21, Bcl-2 and Bcl-Xl in MM cells. In addition, MRK003 caused an upregulation of pAkt, indicating crosstalk with the PI3K/Akt pathway.

1. Bruceine D from Brucea javanica, may have the potential to be used as a natural viricide, or a lead compound for new viricides. 2. Bruceine D inhibits the growth of three pancreatic cancer cell lines, i.e., PANC-1, SW199 and CAPAN-1; induces cytotoxicity in Capan-2 cells via the induction of cellular apoptosis involving the mitochondrial pathway.
