ARN 077 is a selective N-acylethanolamine acid amidase (NAAA) inhibitor (IC50: 7 nM for human NAAA). ARN 077 significantly increases palmitoyl ethanolamine (PEA) levels within the CNS.
ARN19874 is a selective, reversible uncompetitive N-acylphosphatidylethanolamine phospholipase D (NAPE-PLD) activity inhibitor. With an IC50 of ~34 μM[1].
ARN-6039 is an orally available inverse agonist of RORγ for Autoimmune Neuroinflammatory Demyelinating Disease. The activity of ARN-6039 against RORγ was demonstrated in a RORγ-activated IL-17A Prom LUCPorter assay in HEK 293 cells (360 nM) and in IL-17 r
ARN24139 is a topoisomerase II poison (IC50= 7.3 μM in a topoisomerase II decatenation assay).1It inhibits proliferation of DU145, HeLa, and A549 cells (IC50s = 4.7, 3.8, and 3.1 μM, respectively). 1.Arencibia, J.M., Brindani, N., Franco-Ulloa, S., et al.Design, synthesis, dynamic docking, biochemical characterization, and in vivo pharmacokinetics studies of novel topoisomerase II poisons with promising antiproliferative activityJ.

ARN19689 is an effective inhibitor of human NAAA, demonstrating high potency in the low nanomolar range (IC 50 = 0.042 μM). The compound acts through a non-covalent mechanism, highlighting its ability to interact with the enzyme for inhibition.
ARN 14494 is a potent serine palmitoyltransferase inhibitor (SPT; IC50 = 27.3 nM). ARN 14494 inhibits synthesis of long chain ceramides and dihydroceramides in an in vitro model of Alzheimer's diease. The compound prevents the synthesis of proinflammatory cytokines and the oxidative stress-related enzymes iNOS and COX-2 in mouse primary cortical astrocytes. ARN 14494 is neuroprotective against β-amyloid 1-42 induced neurotoxicity in primary cortical neurons co-cultured with astrocytes.
ARN14988 is a potent inhibitor of acid ceramidase (IC50 = 12.8 nM for the human enzyme). It inhibits acid ceramidase activity and increases levels of C16 dihydro ceramide and C16 ceramide in A375, G361, M14, MeWo, MNT-1, and SK-MEL-28 melanoma cells. ARN14988 also reduces growth of A375 and G361 melanoma cells (EC50s = 41.8 and 67.7 μM, respectively).
ARN16186; ARN 16186; ARN-16186 is a phosphatidylinositol 3-kinase (PI3K) inhibitor with potential antineoplastic activity. This compound targets and inhibits the PI3K enzyme, which may result in the inhibition of the PI3K Akt signaling pathway and thus inhibit cell growth and induce apoptosis in susceptible tumor cell populations.
ARN1468 (compound 5) is a highly effective orally active inhibitor of serpins. Inhibition of serpins activity by ARN1468 enables release of proteases, thereby reducing prion accumulation. ARN1468 demonstrates pronounced anti-prion effects in ScGT1 RML, ScGT1 22L, ScN2a RML, and ScN2a 22L cell lines, with EC 50 values of 8.64, 19.3, 11.2, and 6.27 μM [1].
