Nolpitantium (SR-140333) is a highly selective nonpeptide antagonist of neurokinin-1 (NK1) receptor. Nolpitantium potently, selectively and competitively inhibited substance P binding to NK1 receptors from various animal species, including humans. In vitro, it was a potent antagonist in functional assays for NK1 receptors such as [Sar9, Met(O2)11]substance P-induced endothelium-dependent relaxation of rabbit pulmonary artery and contraction of guinea-pig ileum. Up to 1 mkM, Nolpitantium had no effect in bioassays for NK2 and NK3 receptors. The antagonism exerted by Nolpitantium toward NK1 receptors was apparently non-competitive, with pD2' values between 9.65 and 10.16 in the different assays. Nolpitantium also blocked in vitro [Sar9, Met(O2)11]substance P-induced release of acetylcholine from rat striatum. In vivo, Nolpitantium exerted highly potent antagonism toward [Sar9, Met(O2)11]substance P-induced hypotension in dogs, bronchoconstriction in guinea-pig) and plasma extravasation in rats. Nolpitantium was found to be effective in the modulation of the inflammatory response and airway remodeling in mice. Nolpitantium is reported to cause antagonism of the SP-induced relaxations of human isolated intralobar pulmonary arterial rings. Nolpitantium also blocked the activation of rat thalamic neurons after nociceptive stimulation. Nolpitantium has been shown to reduce the severity of inflammation in trinitrobenzene sulfonic acid-induced colitis in the rat colon. Nolpitantium inhibited mustard oil-induced plasma protein extravasations in the dorsal skin of the rat hind paw. Nolpitantium had been in some phase II clinical trials but further studies were discontinued.

PCI-27483 is a reversible small-molecule inhibitor of activated factor VII (factor VIIa) with potential antineoplastic and antithrombotic activities. FVII, a serine protease, becomes activated (FVIIa) upon binding with TF forming the FVIIa/TF complex, which induces intracellular signaling pathways by activating protease activated receptor 2 (PAR-2). Upon subcutaneous administration, factor VIIa inhibitor PCI-27483 selectively inhibits factor FVIIa in the VIIa/TF complex, which may prevent PAR-2 activation and PAR2-mediated signal transduction pathways, thereby inhibiting tumor cell proliferation, angiogenesis, and metastasis of TF-overexpressing tumor cells. A phase I study in healthy volunteers was conducted to assess the PD and PK profiles of PCI- 27483 following a single, SC injection. The halflife of PCI-27483 was 10-12 h. The International Normalized Ratio (INR) was strongly correlated with drug plasma concentration. PCI-27483 was well tolerated. This compound has being evaluated in a phase Ib/II trial in patients with pancreatic cancer receiving treatment with gemcitabine. However, no recent development has been reported. The compound was originally developed by Celera, then licensed to Pharmacyclics (acquired by Abbvie in 2015) later. In 2012, the product was licensed to Novo Nordisk by Pharmacyclics for disease outside of oncology.

PF-05175157 exhibited good potencies against the two isoforms of the Acetyl-CoA carboxylase enzyme (ACC1 and ACC2) from human and rat. PF-05175157 has undergone multiple clinical trials in healthy volunteers and for the treatment of diabetes mellitus. PF-05175157 was in the phase II when the development was discontinued due to safety concerns. Among potential barriers for the use of ACC inhibitors in humans include concerns of increased risk of myocardial injury following an ischemic event. PF-05175157 reduced the multiplication of West Nile virus (WNV), dengue virus (DENV), and Zika virus (ZIKV) in cultured cells, which is compatible with the predicted broad spectrum of host targeting antivirals. PF-05175157 reduced the peak of viremia in WNV-infected mice, supporting that ACC is a valuable target for antiviral intervention. PF05175157 also reduced the viral burden in the kidney of infected mice.

Napabucasin (BBI608) is an orally administered small molecule that blocks stem cell activity in cancer cells by targeting the signal transducer and activator of transcription 3 pathway, which is over-activated in many types of cancer and has been shown to be an important pathway in cancer stem cell-mediated propagation of cancer. Napabucasin has already shown promising efficacy on different cancer types, both as a monotherapy and in combination with conventional chemotherapeutic agents. Early-phase trials have shown promising anti-tumor efficacy when patients are treated with napabucasin in combination with standard chemotherapy agents, and preclinical results suggest that napabucasin can synergize with chemotherapy agents, such as paclitaxel, to potentially overcome drug resistance. Encouraging phase Ib/II trial results warrant further clinical study with napabucasin and paclitaxel combination therapy, especially in malignancies where there is an urgent and unmet need for effective therapeutics, such as in patients with advanced pancreatic adenocarcinoma.

Granotapide (JTT-130) has been studied for use in treatment of diabetes mellitus type II. This intestine-specific microsomal transfer protein inhibitor has hypoglycemic effects. Granotapide is thought to block fat absorption, which results in enhanced glucose-stimulated insulin secretion and enhanced insulin sensitivity. In an animal study, granotapide improved hyperglycemia and dyslipidemia via a mechanism independent of suppression of food intake. Granotapide enhances glucagon-like peptide-1 secretion and reduces lipotoxicity. A phase 2 study has been conducted to evaluate the effect of JTT-130 on diabetes as well as the safety and tolerability of JTT-130 in obese Type 2 diabetic patients.
