PX-12 (PX12) (1-methylpropyl 2-imidazolyl disulfide) is a small-molecule inhibitor of Trx-1 (thioredoxin-1), stimulates apoptosis, down-regulates HIF-1α and vascular endothelial growth factor (VEGF) and inhibits tumor growth in animal models. Since high levels of Trx-1 have been associated with colorectal, gastric and lung cancers, PX-12 is indicated as a potential cancer treatment in combination with chemotherapy for patients with advanced metastatic cancer. Initial trials correlated doses of Px-12 with increased patient survival.

Astragaloside IV (AS-IV), an active component isolated from Astragalus membranaceus, suppresses the activation of ERK1 2 and JNK, and downregulates matrix metalloproteases (MMP)-2, (MMP)-9 in MDA-MB-231 breast cancer cells.

It has diverse protective effects for the cardiovascular, immune, digestive, and nervous systems. In particular, it reduces myocardial infarct size in dogs when administered prior to coronary ligation and reduces reperfusion arrhythmias in isolated rat hearts.

P32/98 hemifumarate is a dipeptidyl peptidase IV (DPP4) inhibitor with hypoglycemic properties that improves insulin sensitivity and β-cell responsiveness in the Zucker diabetic rat model, and may be useful in studies of type 2 diabetes and colitis.

Nateglinide (Senaglinide) is an oral hypoglycemic agent and amino acid derivative that stimulates insulin secretion from the pancreas and is used in the therapy of type 2 diabetes. Nateglinide has been linked to rare instances of clinically apparent acute liver injury.

Ganciclovir sodium (Cytovene IV sodium) is the sodium salt of Ganciclovir with antiviral activity, especially against cytomegalovirus (CMV) and herpes simplex virus type 1 (HSV-1).

Talabostat (PT100, Val-boroPro) is a potent, nonselective and orally available dipeptidyl peptidase IV (DPP-IV) inhibitor with a Ki of 0.18 nM. Talabostat is a nonselective DPP-IV inhibitor, inhibiting DPP8 9, FAP, DPP2 and some other DASH family enzymes essentially as potently as it inhibits DPP-IV[1]. Talabostat stimulates the immune system by triggering a proinflammatory form of cell death in monocytes and macrophages known as pyroptosis. The inhibition of two serine proteases, DPP8 and DPP9, activates the proprotein form of caspase-1 independent of the inflammasome adaptor ASC[2]. Talabostat competitively inhibits the dipeptidyl peptidase (DPP) activity of FAP and CD26 DPP-IV, and there is a high-affinity interaction with the catalytic site due to the formation of a complex between Ser630 624 and the boron of talabostat[3]. Talabostat can stimulate immune responses against tumors involving both the innate and adaptive branches of the immune system. In WEHI 164 fibrosarcoma and EL4 and A20 2J lymphoma models, PT-100 causes regression and rejection of tumors. The antitumor effect appears to involve tumor-specific CTL and protective immunological memory. Talabostat treatment of WEHI 164-inoculated mice increases mRNA expression of cytokines and chemokines known to promote T-cell priming and chemoattraction of T cells and innate effector cells[3]. Talabostat treated mice show significant less fibrosis and FAP expression is reduced. Upon PT100 treatment, significant differences in the MMP-12, MIP-1α, and MCP-3 mRNA expression levels in the lungs are also observed. Treatment with PT100 in this murine model of pulmonary fibrosis has an anti-fibro-proliferative effect and increases macrophage activation[4]. [1]. Connolly BA, et al.

Bavisant dihydrochloride hydrate (JNJ31001074AAC) is a highly selective, orally active antagonist of the human H3 receptor with a novel mechanism of action related to wakefulness and cognition, and it has potential as a treatment for ADHD. In a clinical trial, the mean change from baseline in the total ADHD-RS-IV score at day 42 was -8.8 in the placebo group versus -9.3, -11.2, and -12.2 in the bavisant 1 mg day, 3 mg day, and 10 mg day groups, respectively; however, the change in the 10 mg day group was not statistically superior to placebo (p=0.161). Statistical comparisons of the 1 mg day and 3 mg day groups with placebo based on a step-down closed testing procedure were not performed. Bavisant has completed a phase II ADHD trial, but no results have been reported [1].

(2S,4R)-Teneligliptin is a selective inhibitor of dipeptidyl peptidase IV (DPP-4).
