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.

Idasanutlin (RG-7388) is a second-generation, orally bioavailable, selective p53-MDM2 antagonist. MDM2 is an important negative regulator of the p 53 tumor suppressor and is expressed at high levels in a large proportion of acute myeloid leukemia (AML). Blocking the MDM2-p53 interaction stabilizes p53 and activates p-53 mediated cell death and inhibition cell growth. Idasanutlin is under clinical trial in phase III for treatment AML and in combinations with others drugs in phase I/II for treatment of multiple myeloma.

Altiratinib, a novel c-MET/TIE-2/VEGFR inhibitor, was able to effectively reduce tumor burden in vivo and block c-MET signaling, cell growth and migration. Altiratinib inhibits not only mechanisms of tumor initiation and progression, but also drug resistance mechanisms in the tumor and microenvironment. Altiratinib durably inhibits MET, both wild-type and mutated forms, in vitro and in vivo. Altiratinib exhibits properties amenable to oral administration and exhibits substantial blood-brain barrier penetration, an attribute of significance for eventual treatment of brain cancers and brain metastases. It is currently in Phase 1 clinical development for the treatment of solid tumors.

KYORIN Pharmaceutical has developed a new sphingosine 1-phosphate (S1P) receptor type 1 agonist, 2-amino-2-propanediol hydrochloride (KRP-203), for immunomodulation in autoimmune diseases and organ transplantation. This drug was in phase II clinical trial for the treatment Ulcerative Colitis, but this study was terminated. In addition, it has been investigated for the treatment of Cutaneous Lupus Erythematosus and Crohn's Disease, these phases II clinical trial studies were successfully completed.

PND-1186, also known as SR-2156 and VS-4718, is a potent FAK inhibitor with a 50% inhibitory concentration (IC50) of 1.5 nM in vitro. PND-1186 has an IC50 of ~100 nM in breast carcinoma cells. PND-1186 is currently being evaluated in a Phase 1 trial in patients with advanced solid tumors. In addition, an ongoing collaboration with Wash U is evaluating PND-1186 in combination with gemcitabine and Abraxane in 1st line pancreatic cancer.

Motesanib (AMG 706), a novel nicotinamide, was identified as a potent, orally bioavailable inhibitor of the VEGFR1/Flt1, VEGFR2/kinase domain receptor/Flk-1, VEGFR3/Flt4 and Kit receptors. Motesanib was expected to reduce vascular permeability and blood flow in human tumours. A phase III trial of motesanib in combination with paclitaxel and carboplatin in non-squamous NSCLC has been terminated by Takeda and subsequently the development was discontinued. Motesanib has also been investigated up to phase II in breast, thyroid, colorectal and gastrointestinal stromal tumours. However, development has been discontinued in these indications.

TG-100115 is a potent dual inhibitor of PI3K-gamma and PI3K-delta. TG-100115 has broad anti-inflammatory activities. TG-100115 provided potent cardioprotection, reducing infarct development and preserving myocardial function. In murine models of asthma and acute stages of chronic obstructive pulmonary disease, aerosolized TG100-115 demonstrated not only markedly inhibited anti-inflammatory activity but also, in the case of the asthma model, improved functional outcome for the test animals. TG-100115 can be used as a potent TRPM7 kinase inhibitor and a potent inhibitor of breast cancer cell migration.

JNJ-38877605 is an orally available, small molecule inhibitor of the proto-oncogene c-Met (hepatocyte growth factor receptor [HGFR]) with potential antineoplastic activity. c-Met inhibitor JNJ-38877605 selectively binds to c-Met, thereby inhibiting c-Met phosphorylation and disrupting c-Met signal transduction pathways. JNJ-38877605 was in Phase I clinical trials. Combined clinical and correlative preclinical studies suggest that renal toxicity of JNJ-38877605 is caused by the formation of species-specific insoluble metabolites. These observations preclude further clinical development of JNJ-38877605.

TAK-063 is a highly potent, selective, and orally active phosphodiesterase 10A (PDE10A) inhibitor with IC50 of 0.30 nM; >15000-fold selectivity over other PDEs. TAK-063 is currently being evaluated in clinical trials for the treatment of schizophrenia. Phosphodiesterase 10A (PDE10A) is a cAMP/cGMP phosphodiesterase highly expressed in medium spiny neurons (MSNs) in the striatum. TAK-063 represents a promising drug for the treatment of schizophrenia with potential for superior safety and tolerability profiles.

INT-131, a novel, non-thiazolidinedione (TZD), selective peroxisome proliferator-activated receptor (PPAR) gamma modulator and partial agonist, which was investigated in phase II of clinical trial for the treatment of type 2 diabetes mellitus (non-insulin dependent diabetes) and Multiple Sclerosis, Relapsing Remitting. The concept of selective modulation involves targeting and activating specific genes to minimize side effects while maintaining therapeutic benefits. In vitro, INT-131 attenuated adipogenic properties, indicating moderate PPAR gamma activation/cofactor recruitment compared with the full agonistic properties of TZD compounds.
