ASC-09 orTMC-310911, a HIV protease inhibitor, participated in phase II clinical for the treatment of Human Immunodeficiency Virus Type 1. However, no recent development has been reported.

Tomivosertib (eFT-508) is a dual inhibitor of MAP kinase-interacting kinases (MNK1 and MNK2) thereby controlling translation. It has potent in vivo antitumor activity in models of diffuse large cell B-cell lymphoma and solid tumors. Tomivosertib acts on multiple points in the cancer immunity cycle simultaneously, underscoring its therapeutic potential as both a monotherapy and in combination with existing checkpoint inhibitor treatments. Preclinical studies suggest combining tomivosertib with a checkpoint inhibitor can overcome mechanisms of resistance to checkpoint inhibitors, resulting in enhanced sensitivity to checkpoint inhibitors and a higher response rate. In addition, preclinical data demonstrate that tomivosertib as a single agent promotes antitumor immunity that persists after stopping drug treatment. Tomivosertib is currently being evaluated in Phase 2 clinical trials in solid tumors and lymphoma. Additionally, tomivosertib may be a new therapeutic for neuropathic pain.

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.

AZD9164 was invented by AstraZeneca as a muscarinic M(3) receptor antagonist for evaluation of the potential as a treatment for chronic obstructive pulmonary disease. However, in 2010 studies were discontinued.

LY2300559 is a dual metabotropic glutamate receptor 2 (mGluR2) positive allosteric modulator and cysteinyl leukotriene receptor 1 (CysLTR1) antagonist. Eli Lilly was developing LY2300559 for the prevention of migraine. LY2300559 development has been discontinued.
