AZD-8330 is a potent, selective, orally active MEK inhibitor that blocks signal transduction pathways implicated in cancer cell proliferation and survival. AZD-8330 has shown tumor suppressive activity in multiple preclinical models of human cancer including melanoma, pancreatic, colon, lung, and breast cancers. AZD-8330 specifically inhibits mitogen-activated protein kinase kinase 1 (MEK or MAP/ERK kinase1), resulting in inhibition of growth factor-mediated cell signaling and tumor cell proliferation. MEK is a key component of the RAS/RAF/MEK/ERK signaling pathway that regulates cell growth; constitutive activation of this pathway has been implicated in many cancers. AZD-8330 had been in phase I clinical trials by AstraZeneca for the treatment of malignancies. However, this research has been discontinued.

Basmisanil (INN) (developmental code names RG-1662, RO5186582) is a highly selective inverse agonist/negative allosteric modulator of α5 subunit-containing GABAA receptors which is under development by Roche for the treatment of cognitive impairment associated with Down syndrome. The phase II trials were recently terminated due to lack of efficacy. This outcome suggests either that the α5-NAM was insufficiently effective to restore neuronal plasticity or alternatively that the hypothesis of excessive GABAergic inhibition obstructing neuronal plasticity does not extend to individuals with DS.

Stilbazium is a pyridinium derivative with considerable anthelminthic activity against some animal nematodes, including Syphacia obvelata, Ancylostoma caninum, Uncinaria stenocephala and Toxocara cati.

AZD-7687 is a potent inhibitor of Diacylglycerol O-acyltransferase 1 (DGAT1) which was developed by AstraZeneca for the treatment obesity and type 2 diabetes mellitus. AZD-7687 reached phase I of clinical trials, but was discontinued by unknown reasons.

Amgen was developing AMG-208, a small molecule inhibitor of c-Met, for the treatment of cancer. AMG-208 shows the potent inhibition of kinase c-Met activity with IC50 of 9 nM in a cell-free assay. Besides, AMG-208 treatment also leads to the inhibition of HGF-mediated c-Met phosphorylation in PC3 cells with IC50 of 46 nM. AMG-208 showed evidence of antitumor activity, particularly in prostate cancer. On December 1, 2014 Amgen completed a phase I trial in solid tumours.
