LY2606368 (Prexasertib) is a small-molecule Chk-1 inhibitors invented by Array and being developed by Eli Lilly and Company. Lilly is responsible for all clinical development and commercialization activities. LY2606368 is advancing in Phase 2 clinical trials for cancer. Prexasertib preferentially binds to and inhibits CHK1 and, to a lesser extent, inhibits CHK2. Chk-1 is a protein kinase that regulates the tumor cell's response to DNA damage often caused by treatment with chemotherapy. In response to DNA damage, Chk-1 blocks cell cycle progression in order to allow for repair of damaged DNA, thereby limiting the efficacy of chemotherapeutic agents. Inhibiting Chk-1 in combination with chemotherapy can enhance tumor cell death by preventing these cells from recovering from DNA damage.

INN:ronopterin [INN]

Class (Stereo):
CHEMICAL (ABSOLUTE)

Vasopharm BIOTECH is developing 4-aminotetrahydrobiopterin (ronopterin, VAS 203), a nitric oxide synthase inhibitor, for the treatment of traumatic brain injury. Ronopterin is an allosteric nitric oxide (NO) synthase inhibitor interacting with the tetrahydrobiopterinbinding site of the enzyme. Pre-clinical, proof-of-principle studies using controlled cortical impact showed that VAS203 had significant and positive effects on elevated intracranial pressure (ICP), which contributes to the deleterious consequences of TBI, as well as on neurological outcome measured with behavioural tests. By targeting both cerebral blood vessels and cerebral tissue in a region-specific manner VAS203 represents a completely novel pharmacological approach to TBI that can be administrated in addition to best standard of care. Ronopterin is currently in development for the treatment of traumatic brain injury.In the phase III clinical trial, ronopterin is administered as a 17 mg/kg intravenous infusion over 48 hours (daily dose of 8.5 mg/kg).

Class (Stereo):
CHEMICAL (ABSOLUTE)


Squalamine is a steroid-polyamine conjugate compound with broad-spectrum antimicrobial activity and anti-angiogenic activity. Squalamine selectively inhibits new blood vessel formation; this activity is thought to be mediated through inhibition of the sodium-hydrogen antiporter sodium-proton exchangers (specifically the NHE3 isoform) causing inhibition of hydrogen ion efflux from endothelial cells, with subsequent reduction of cellular proliferation. Studies in tumor-bearing mice have shown that squalamine inhibits angiogenesis and tumor growth in xenograft models of lung, breast, ovarian, and prostate cancer and in brain and breast allograft tumor models in rats. Squalamine also has been shown to prevent lung metastases in the murine Lewis lung carcinoma model, both as a single agent and in combination with various other chemotherapeutics. Squalamine does not appear to have substantial direct effects on primary tumor growth in animal models when administered as a single agent. However, enhanced antitumor responses are observed when squalamine is administered in combination with cytotoxic chemotherapeutic agents when compared with cytotoxic agents used alone. Squalamine was studied as a potential cancer drug and as a potential treatment for wet macular degeneration but as of 2018 had not succeeded in Phase III trials for any use.

Onalespib (AT13387; (2,4-dihydroxy-5-isopropyl-phenyl)-[5-(4-methyl-piperazin-1-ylmethyl)-1,3-dihydro-isoindol-2-yl] methanone, l-lactic acid salt), is wholly owned by Astex, a novel, high-affinity HSP90 inhibitor, which is currently being clinically tested, has shown activity against a wide array of tumor cell lines, including lung cancer cell lines. As a targeted inhibitor of Hsp90, onalespib has the potential to control the proliferation of multiple solid tumors and hematological malignancies where uncontrolled cell growth is dependent on the interaction between Hsp90 and its client proteins. Astex is pursuing an approach based on the observation that addition of onalespib to a molecularly targeted agent may delay the emergence of resistance to the agent, and hence prolong the window of therapeutic benefit. Onalespib is currently being evaluated via a CRADA with the National Cancer Institute (NCI) in various tumor types, and in a Phase 1/2 clinical study in combination with AT7519, Astex CDK inhibitor.

Class (Stereo):
CHEMICAL (RACEMIC)


Pirlindole is a selective and reversible inhibitor of monoamine oxidase (MAO) subtype A (MAO-A). It exerts an inhibitory effect on noradrenaline and 5-hydroxytryptamine reuptakes. It has no effect on the dopaminergic and cholinergic systems. It has only a low potential for amplifying tyramine and noradrenaline pressor effect, which makes one expect that it will not be at the basis of a ‘cheese effect’. Pirlindole was approved in some European and non-European countries for the treatment of depression. The antidepressant efficacy and safety of pirlindole have been demonstrated in a number of placebo- and active comparator-controlled studies and are supported by many years of clinical experience in the treatment of depression. The drug's efficacy and safety have also been demonstrated in the treatment of fibromyalgia syndrome. Pirlindole has a favorable tolerability profile, with no deleterious effect on cardiovascular dynamics. The effect of pirlindole on sensorimotor performance relevant to driving a motor vehicle is similar to that of placebo, as pirlindole appears to have an activating rather than a sedating antidepressant profile. Pirlindole prevented qualitative alteration (transformation) in the catalytic activity of membrane-bound type A monoamine oxidases (MAO-A), pathogenetically important for the development of the audiogenic seizures.
Dovitinib is an orally active small molecule that exhibits potent inhibitory activity against multiple receptor tyrosine kinases (RTK) involved in tumor growth and angiogenesis. Dovitinib strongly binds to fibroblast growth factor receptor 3 (FGFR3) and inhibits its phosphorylation, which may result in the inhibition of tumor cell proliferation and the induction of tumor cell death. In addition, this agent may inhibit other members of the RTK superfamily, including the vascular endothelial growth factor receptor; fibroblast growth factor receptor 1; platelet-derived growth factor receptor type 3; FMS-like tyrosine kinase 3; stem cell factor receptor (c-KIT); and colony-stimulating factor receptor 1; this may result in an additional reduction in cellular proliferation and angiogenesis, and the induction of tumor cell apoptosis. There are several ongoing Phase I/III clinical trials for dovitinib.

Halofuginone is a low molecular weight quinazolinone alkaloid, and a potent inhibitor of collagen alpha1(I) and matrix metalloproteinase 2 (MMP-2) gene expression. Halofuginone also effectively suppresses tumor progression and metastasis in mice. Halofuginone is a potent inhibitor of collagen a1(I) and matrix metalloproteinase 2 (MMP-2) gene expression. Halofuginone also suppresses extracellular matrix deposition and cell proliferation. Also was shown that halofuginone increased apoptosis in α smooth muscle actin- and prolyl 4-hydroxylase β-expressing cells in mdx diaphragm and in myofibroblasts, the major source of extracellular matrix. The profound antitumoral effect of halofuginone is attributed to its combined inhibition of tumour-stromal support, vascularization, invasiveness, and cell proliferation. HT-100 (delayed-release halofuginone), currently in clinical phase 1b/2a in five U.S. hospitals, is a small molecule drug candidate taken orally for the treatment of Duchenne muscular dystrophy (DMD) patients primarily through its ability to reduce fibrosis and inflammation and promote muscle fiber regeneration. The medicine candidate has been granted orphan drug designation in the U.S. and the EU — meaning it has been commercially undeveloped due to its limited profitability — and fast-track designation in the U.S. — an FDA process that aims to facilitate the development and patients’ reach to novel therapies for unmet medical needs.
