RO-5045337 (RG7112) is a small molecule that binds to a MDM2, a negative regulator of tumor-supressor protein p53. It was discovered by Roche and investigated in clinical trials against solid tumors, leukemias and sarcomas.

RO-638695 (also known as Miridesap, CPHPC and GSK-2315698) is an antineoplastic and a serum amyloid P component inhibitor. RO-638695 almost completely depletes circulating serum amyloid P component (SAP), but a small amount of SAP is left for recognition by subsequently administered therapeutic IgG anti-SAP antibodies. SAP is a blood protein that is the target of a novel immunotherapy approach. RO-638695 has therefore been evaluated in phase I and II clinical trials for its safety and potential in treatment of diseases like Alzheimer’s disease, HIV infection and other diseases with systemic amyloid deposition.

Aspaminol (1,1 diphenyl-3-piperidinobutanol hydrochloride) is a nonspecific smooth muscle relaxant. It inhibits calcium uptake. The relaxation of smooth muscle induced by aspaminol may be due to a combining of aspaminol with calcium ions at the binding sites on the surface of smooth muscle, thus decreasing the supply of calcium ions to the contractile element.

Arena Pharmaceuticals was developing APD-597 (JNJ-38431055), a small molecule, an orally active agonist of the G-protein coupled receptor 119 (GPR119), for the treatment of Type 2 diabetes mellitus. JNJ-38431055 was selected for preclinical development based on a good balance between agonist potency, intrinsic activity and in particular on its good solubility and reduced drug-drug interaction potential. In addition, extensive in vivo studies showed a more favorable metabolic profile that may avoid the generation of long-lasting metabolites with the potential to accumulate in clinical studies. In humans, single-dose oral JNJ-38431055 increased postmeal plasma glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), and peptide YY (PYY) concentrations but did not significantly decrease glucose excursion or increase insulin secretion. However, in a graded glucose infusion study, JNJ-38431055 was shown to induce a higher insulin secretion rate (ISR) relative to placebo at elevated plasma glucose levels. These studies provide evidence for the potential efficacy of JNJ-38431055 as an antidiabetes agent in humans.

Serabelisib (INK1117 and TAK-117) is an orally bioavailable, PI3K p110α- isoform-specific inhibitor with an in vitro IC50 of 15 nM, highly selective against other isoforms (p110β, p110γ, and p110δ) and mTOR (no significant inhibitions at 1 μM concentration). It displayed significant efficacy in several PI3Kα mutant-specific preclinical mouse xenograft tumor models, and blocked signaling to Akt and inhibited the growth of cancer cells harboring wild-type or mutated p110α. Preclinical studies showed TAK-117 to have the low potential for disrupting glucose metabolism or for causing cardiac adverse events; in rats and monkeys, doses up to 50 mg/kg/day were well tolerated. Serabelisib is currently under clinical evaluation.

Talopram (Lu 3-010) is a selective inhibitor norepinephrine transporter belonging to the antidepressants of the thymoleptic group.

Briciclib (also known as ON-013105 and ON-014185) has the potential of targeting and inhibition of eukaryotic translation initiation factor 4E (eIF4E) for solid cancers. eIF4E is a proto-oncogene that promotes translation of several genes essential for cellular proliferation (cyclin D1, c-Myc, mTOR), survival (Akt), angiogenesis (VEGF), and metastasis (MMP9). Overexpression of eIF4E has been observed in almost all major groups of cancers and has been shown to induce increased expression of cyclin D1 and c-Myc). An intravenous formulation of briciclib was being investigated in the Phase 1 clinical trial. The purpose of the study was to determine the highest dose of briciclib that could be given safely in patients with relapsed/refractory Lymphoma or B-cell Acute Lymphocytic Leukemia (Philadelphia chromosome negative). However, this study was terminated because of the lack of available clinical drug supply. In addition, briciclib was also involved in phase I clinical trials with advanced cancer and solid tumors, to determine the highest dose that can be safely given.

Naquotinib (ASP8273) is an orally available, irreversible, mutant-selective, epidermal growth factor receptor (EGFR) inhibitor, with potential antineoplastic activity. Naquotinib was found by mass spectrometry to covalently bind to a mutant EGFR (L858R/ T790M) via cysteine residue 797 in the kinase domain of EGFR with long-lasting inhibition of EGFR phosphorylation for 24 h. In the NSCLC cell lines harboring the above EGFR mutations, Naquotinib had IC50 values of 8-33 nM toward EGFR mutants, more potently than that of WT EGFR (IC50 value of 230 nM). In mouse xenograft models, Naquotinib induced complete regression of the tumors after 14 days of treatment. ASP8273 even showed activity in mutant EGFR cell line which is resistant to other EGFR TKIs. Naquotinib is in phase III clinical trials for the oral treatment of EGFR mutated non-small cell lung cancer (NSCLC).

2-Iminobiotin (2-IB) is a cyclic guanidino analog of biotin (Vitamin B7) and combined neuronal and inducible (but not endothelial) nitric oxide synthase inhibitor that has been demonstrated to improve neuroprotection in animal models of hypoxic-ischemic Brain Injury. While the exact mechanism of action has yet to be defined, 2-Iminobiotin potentially protects against hypoxic-ischemic brain damage by preventing nitric oxide or peroxynitrite-induced mitochondrial damage. In preclinical models, 2-Iminobiotin provides gender-specific neuroprotection against hypoxia-ischemia in neonatal rats by a NO-independent mechanism.

BMS-833923 was discovered by Exelixis and was out-licensed to Bristol-Myers Squibb. BMS-833923 is an orally bioavailable Smoothened antagonist. BMS-833923 reduces hedgehog pathway activity, decreases cell proliferation and induces apoptosis via the intrinsic pathway in esophageal adenocarcinoma (EAC) cell lines. BMS-833923 dose-dependently affects canonical and prostate hedgehog signature gene transcription in vitro. BMS-833923 is in phase II clinical trials for the treatment of chronic myeloid leukaemia.
