Varlitinib (Alternative Names: ARRY-334543; ARRY-543; ASLAN-001; Varlitinib tosylate) is a small molecule based reversible pan-HER inhibitor of EGFR, HER2 and HER4. In response to the binding of various ligands, these kinases undergo heterodimerisation and homodimerization, resulting in activation of numerous growth factor signaling pathways, by inhibiting the activation of the HER receptors via drug, effects such as shrinkage of the tumor and longer survival can be anticipated. In a large variety of cancers, the overexpression and/or constitutive activation of EGFR and HER2 are often observed and frequently correlate with poor clinical prognosis. Licensed from Array BioPharma with global rights for all indications, varlitinib is being developed as first-in-class drug for cholangiocarcinoma, gastric and colorectal cancer, and as best-in-class drug for breast cancer.

Rupintrivir is a peptide aldehyde that targets the human rhinovirus (HRV) 3C proteinase enzyme and has the potential for the treatment of the common cold. Rupintrivir is derived from AG-6084 - in order to develop human rhinovirus 3C protease inhibitors with improved pharmacological properties, Agouron replaced the backbone amide moiety of the series which yielded AG-6084, with a ketomethylene isostere. A phase II efficacy study has been completed in healthy patients infected with the rhinovirus. Ruprintrivir was well tolerated; blood-tinged mucus and nasal passage irritation were the most common adverse effects reported. Pharmacokinetic analysis of plasma and nasal ruprintrivir concentrations revealed intranasal drug residence with minimal systemic absorption. The fact that rupintrivir is active against noroviruses belonging to genogroup I (Norwalk virus), genogroup V (murine norovirus), and the recombinant 3C-like protease of a GII norovirus suggests that the drug exerts cross-genotypic anti-norovirus activity and will thus most likely be effective against the clinically relevant human norovirus strains. Rupintrivir is also a high affinity inhibitor of Enterovirus-71 3C protease.

Org 25935 (SCH 900435) is a synthetic drug developed by Organon International, which acts as a selective inhibitor of the glycine transporter GlyT-1. In human trial for prevention of relapse in alcohol-dependent patients in Org 25935 demonstrated no benefit over placebo in preventing alcohol relapse. Org 25935 was tested as an adjunctive treatment to atypical antipsychotics in predominant persistent negative symptoms of schizophrenia, where it did not differ significantly from placebo in reducing negative symptoms or improving cognitive functioning. Clinical trials against panic disorder did not show any benefit compared to placebo.

TNP-470 (AGM-1470, (3R,4S,5S,6R)-5-methoxy-4- [(2R,3R)-2-methyl-3-(3-methyl-2-butenyl) -oxiranyl]-1-oxaspiro[2,5]oct-6-yl(chloroacetyl) carbamate) is an anti-angiogenic, semisynthetic analogue of fumagillin, a known antibiotic secreted by the fungus Aspergillus fumigatus fresenius, which is under clinical development for the treatment of cancer by Takeda Chemical Industries Ltd. in Japan and TAP Pharmaceuticals, Inc. in the United States. TNP-470 binds to and irreversibly inactivates methionine aminopeptidase-2 (MetAP2), resulting in endothelial cell cycle arrest late in the G1 phase and inhibition of tumor angiogenesis. This agent may also induce the p53 pathway, thereby stimulating the production of cyclin-dependent kinase inhibitor p21 and inhibiting angiogenesis. In early clinical reports, TNP-470 is tolerated up to 177 mg/m(2) with neurotoxic effects (fatigue, vertigo, ataxia, and loss of concentration) being the principal dose-limiting toxicity (DLT). TNP-470 is being evaluated in Phase I-II trials in the US in patients with Kaposi’s sarcoma, cervical cancer, breast cancer, brain cancer, prostate cancer and renal cell carcinoma.

Quilostigmine (also known as NXX-066) is an isoquinolinecarboxylate patented by Hoechst-Roussel Pharmaceuticals Inc as a memory enhancer. Quilostigmine acts as acetylcholinesterase inhibitor and studies as a potential drug for treating Alzheimer’s disease. Quilostigmine is well absorbed from the gastrointestinal tract, but the oral bioavailability poor to moderate in rats and dogs because of pre-systemic metabolism. In preclinical studies has demonstrated activity in animal models of memory function. In clinical trials, Quilostigmine was well tolerated in healthy subjects up to a single dose of 64 mg and multiple doses of 60 mg QD for seven days

Betulinic acid (BA) is a plant-derived pentacyclic triterpenoid that exerts potent anti-cancer effects in vitro and in vivo. It`s anticancer property is linked to its ability to induce apoptotic cell death in cancer cells by triggering the mitochondrial pathway of apoptosis. In contrast to the cytotoxicity of betulinic acid against a variety of cancer types, normal cells and tissue are relatively resistant to betulinic acid, pointing to a therapeutic window. Compounds that exert a direct action on mitochondria present promising experimental cancer therapeutics, since they may trigger cell death under circumstances in which standard chemotherapeutics fail. Thus, mitochondrion-targeted agents such as betulinic acid hold great promise as a novel therapeutic strategy in the treatment of human cancers. Betulinic acid has antiretroviral, antimalarial, and anti-inflammatory properties. Betulinic acid exerts its inhibitory effect by preventing topoisomerase I-DNA interaction as a result of which the 'cleavable complex' is not formed. In consequence, it also acts as an antagonist to camptothecin-mediated cleavage. The antitumor pharmacological effects of BA consist of triggering apoptosis via the mitochondrial pathway, regulating the cell cycle and the angiogenic pathway via factors, including specificity protein transcription factors, cyclin D1 and epidermal growth factor receptor, inhibiting the signal transducer and activator of transcription 3 and nuclear factor‑κB signaling pathways, preventing the invasion and metastasis of tumor cells, and affecting the expression of topoisomerase I, p53 and lamin B1. Betulinic Acid has also been used in trials studying the treatment of Dysplastic Nevus Syndrome. Betulinic acid acts as anti-melanoma agent through inhibiting aminopeptidase N activity with IC50 of 7.3 uM. Betulinic acid is an inhibitor of HIV-1 with EC50 of 1.4 uM.

CPI-613 is a lipoate derivative synthesized to be catalytically inert but to potentially mimic lipoate catalytic intermediates. The drug is in phase II of clinical trials for the treatment of Myelodysplastic syndromes; Pancreatic cancer; Small cell lung cancer; Solid tumors; Bile duct cancer; Acute Myeloid leukemia. The mechanism of CPI-613 action can be explained by (I) inhibition of tumor cell pyruvate dehydrogenase complex (PDC) through activation of pyruvate dehydrogenase kinases leading to inactivating phosphorylation of the E1alpha-subunit of PDC; and (II) inhibition of alpha-ketoglutarate dehydrogenase.

Carabersat is an anticonvulsant devoid of cardiovascular side effects with minimal central nervous system adverse actions. Carabersat does not bind to ion channels, purinergic, aminergic, opioid and other peptidergic receptors. It selectively interacts with its own binding site, which is not yet elucidated. Carabersat has no effect on sodium channels, GABAergic or glutamate pathways. Carabersat had been in phase II clinical trials for the treatment of epilepsy. It has a potential action in preventing migraines because it acts through an inhibition of the cortical spreading depression trigeminal nerve-induced vasodilatation in cats. Its good therapeutic index and the markedly reduced neurological impairments could make it a useful agent for migraine prophylaxis pending efficacy parameters of controlled studies, which are underway.
