ADX-71149 (JNJ-40411813), a phenylpiperidine-substituted pyridone, is positive allosteric modulator (PAM) metabotropic glutamate type 2 (mGlu2) receptor activity. In fed rats, JNJ-40411813 was rapidly absorbed with an absolute oral bioavailability of 31%. ADX-71149 (JNJ-40411813) demonstrates antipsychotic activity in vivo rodents experiments. ADX-71149 (JNJ-40411813) is being jointly developed by Addex Therapeutics and Janssen Pharmaceuticals, a Johnson & Johnson company, for the treatment of epilepsy. Addex Therapeutics was also developing the candidate for schizophrenia, major depressive disorder and anxiety disorders. However, development in these indications has been discontinued.

Derazantinib (ARQ 087) is an investigational, oral, multi-kinase inhibitor designed to preferentially inhibit the FGFR family of kinases with demonstrated activity in FGFR2 genetic alterations, including fusions. In human cancers, FGFRs have been found to be dysregulated by multiple mechanisms, including aberrant expression, mutations, chromosomal rearrangements, and amplifications. FGFR dysregulation has been identified as a driver in a number of cancers, including iCCA, cholangiocarcinoma, bladder, endometrial, breast, gastric, lung and ovarian. Current scientific literature suggests FGFR alterations exist in anywhere from 5% to 40% of these cancers. Derazantinib is a potent FGFR inhibitor that shows strong anti-proliferative activity in cell lines harboring FGFR2 alterations. In clinical testing, the molecule has demonstrated activity in cancerous tumors harboring FGFR2 fusions in iCCA and bladder cancers.

BAY-86-9596 (D-18F-FMT, or O-18F-fluoromethyl-D-tyrosine) was developed as an agent not only for tumor detection but also for monitoring early-phase response to radiation therapy by positron emission tomography (PET). This drug participated in clinical trials for patients with inflammation and solid tumors, but further information about trials is not available.

AZD3839 is a potent and selective BACE1 inhibitor with about 14-fold selectivity over BACE2. In SH-SY5Y cells, AZD3839 efficiently decreases the Aβ40 levels and decreases the formation of sAPPβ. AZD3839 also decreases the Aβ40 levels secreted from C57BL/6 mouse primary cortical neurons, N2A cells, and Dunkin-Hartley guinea pig primary cortical neurons. AZD3839 causes in vitro BACE1 inhibition in the cell assay with the IC50 value of 16.7 nM. In C57BL/6 mice, AZD3839 (69 mg/kg, p.o.) causes a dose- and time-dependent reduction of plasma and brain Aβ. In guinea pig and non-human primates, AZD3839 also inhibits Aβ generation. AZD3839 has been used in phase I clinical trials studying the basic science of Safety and Tolerability. However future development has been discontinued.
