Cinobufotalin, the bufadienolide isolated from toad venom, has displayed antitumor activities in many in vitro systems. It has been shown that cinobufotalin induced significant apoptosis in cultured human lymphoma U-937 cells. It induced DNA fragmentation, mitochondrial membrane potential decrease, and reactive oxygen species (ROS) production in U-937 cells. Cinobufotalin induces cytotoxic effect in cultured lung cancer cells. Cinobufotalin (1/5 mg/kg, i.p. twice daily, for 7 days) significantly inhibited A549 xenograft growth in mice. Further, same cinobufotalin administration improved mice survival at week five. Cinobufotalin administration didn’t significantly affect mice body weight, indicating the relative safety of this regimen. Thus, cinobufotalin inhibits A549 xenograft growth in vivo and improves mice survival.

TRC-150094 is a synthetic compound that displays the capacity to stimulate energy expenditure. TRC-150094 increases whole body energy expenditure, increases mitochondrial fatty acid oxidation (FAO), and reduces abdominal adiposity in rats fed a high-fat diet. TRC-150094 attenuates the progression of hypertension, insulin resistance, dysglycemia, and atherogenic dyslipidemia, factors reported to signify significant cardiovascular (CV) risk amongst viscerally obese dysglycemic subjects. Moreover, at organ level, TRC150094 reduced steatohepatitis, reduced progression of nephropathy, and preserved cardiac contractile function. Pharmacological profile of TRC-150094 may constitute a promising new class of molecules that may have a potential beneficial therapeutic approach for the treatment of nontraditional CV risk factors and may reduce residual risk in viscerally obese dysglycemic patients. Moreover, the observed metabolic and functional effects on skeletal muscle suggest that TRC-150094 as a therapy may help to facilitate adherence to prescribed exercise, which would remain the mainstay along with diet control in such patients. Simultaneous systemic administration of TRC-150094 to rats receiving an high-fat diet results in a reduction in fat accumulation within the liver and a marked reduction in adipose tissue mass. TRC-150094 is in phase-III clinical trials for the treatment of diabetes mellitus, hypertension and dyslipidaemias (adjunctive treatment) in India.

p53 is a critical tumor suppressor and is the most frequently inactivated gene in human cancer. Inhibition of the interaction of p53 with its negative regulator MDM2 represents a promising clinical strategy to treat p53 wild-type tumors. AMG 232 is a potential best-in-class inhibitor of the MDM2-p53 interaction and is currently in clinical trials. Based on X-ray cocrystal structures a model of AMG 232 bound to MDM2 was developed. The model shows that the m-chlorophenyl, the p-chlorophenyl, and C-linked isopropyl fragments of AMG 232 bind to the Leu 26(p53), Trp 23(p53), and Phe 19(p53) pockets of MDM2, respectively. The carboxylic acid forms a salt bridge with His 96 and the isopropyl sulfone forms a novel interaction with the glycine shelf region of MDM2. AMG 232 in phase II in combination with trametinib and dabrafenib in subjects with metastatic melanoma; in phase I for the treatment of solid tumors, multiple myeloma and Acute Myeloid Leukemia.

4‐Chlorokynurenine (AV-101) is a neuropharmaceutical drug candidate in development for the treatment of major depressive disorder. Pharmacology studies conducted in rodent models have demonstrated AV-101’s antihyperalgesic activity in models of facilitated pain processing was seen at serum concentrations ranging from 150–300 M. In addition, AV-101 has been shown to be neuroprotective activity against an intrahippocampal injection of quinolinic acid, reductions in seizures, and antidepressive activity. An oral prodrug, AV-101, which, in the brain, is converted into one of the most potent and selective GlyB site antagonists of the NMDAR, has been demonstrated to be active in animal models of neuropathic pain. The two Phase 1 studies were designed to assess the safety and pharmacokinetics of AV-101, over a wide dose range, after daily dosing for 14-days. AV-101 has excellent safety and PK characteristics providing support for advancing AV-101 into Phase 2 studies in neuropathic pain.

VLX600 - is a lipophilic cation-based triazinoindolyl-hydrazone compound and mitochondrial oxidative phosphorylation (OxPhos) inhibitor, with potential antineoplastic activity. VLX600 is designed to increase the efficacy of radiotherapy and to kill cancer cells that survive traditional chemotherapy. VLX 600 is a small molecule that inhibits deubiquitinating enzymes USP14 (a ubiquitin thiolesterase) and UCHL5 (a carboxypeptidase). Upon infusion, in normal cells and proliferating tumor cells where glucose is readily available, inhibition of OxPhos by VLX600 induces a hypoxia-inducible factor 1-alpha (HIF-1alpha)-dependent shift to, and an increase in glycolysis. Glycolysis alone does not produce enough energy to support the growth of tumor cells in this environment, and the induction of autophagy occurs. In the metabolically compromised tumor microenvironment, the availability of oxygen and glucose is limited due to poor vascularization and perfusion of tumor micro-areas. Tumor cells growing in this environment are thus unable to compensate for decreased mitochondrial function by increasing glycolysis. This leads to nutrient depletion, decreased energy production, induction of autophagy, tumor cell death and an inhibition of cell proliferation in quiescent tumor cells. Mitochondrial OxPhos, which is hyperactivated in cancer cells, plays a key role in the promotion of cancer cell proliferation. VLX-600 is in phase I clinical trials for the treatment of solid tumours. This compound was originally jointly discovered and developed by Vivolux and Karolinska Institute.

Olodanrigan (EMA-401) is an angiotensin II type 2 receptor antagonist. Olodanrigan may act on paracrine/autocrine mechanisms at peripheral nerve terminals, or intracrine mechanisms, to reduce neuropathic pain signalling in AngII/NGF/TRPV1-convergent pathways. Olodanrigan is being developed by Novartis for the treatment of neuropathic pain.
