CHEMICAL (ABSOLUTE)



Altinicline (SIB-1508Y, SIB-1765F) is a drug which acts as an agonist at neural nicotinic acetylcholine receptors with high selectivity for the α4β2 subtype. It stimulates release of dopamine and acetylcholine in the brain in both rodent and primate models, and progressed as far as Phase II clinical trials for Parkinson's disease, where "no antiparkinsonian or cognitive-enhancing effects were demonstrated", although its current status is unclear.

Elinogrel, previously known as PRT060128 or PRT128, is a direct-acting, reversible P2Y12 inhibitor for both intravenous and oral administration. Elinogrel has been tested in 2 phase II studies for the treatment of acute coronary syndrome, myocardial infarction and prevention of secondary thrombotic events. Elinogrel therapy was associated with an increased incidence of dyspnea and incidence of elevated liver transaminases. The development of the drug was terminated in January 2012 by Novartis.

Cositecan (BNP1350) is semi-synthetic silicon-containing camptothecin and an inhibitor of topoisomerase I. It was engineered by BioNumerik Pharmaceuticals for superior oral bioavailability, lactone stability, and insensitivity to Pgp/MRP/LRP drug resistance. The compound shows a broad spectrum of activity in experimental human tumors. Cositecan was investigated in clinical trials in patients with malignant melanoma, relapsed or refractory non-small cell lung cancer, ovarian and peritoneal cancer, malignant glioma. The compound had little activity in recurrent glioma and ovarian cancer.
Indoximod is an orally available Indoleamine 2,3-dioxigenase inhibitor. It shows higher potency in reversing IDO-mediated T cell suppression. Indoximod improves the efficacy of multiple chemotherapeutics agents and some immunological checkpoints mediators in Phase I/II clinical studies for metastatic breast cancer, metastatic melanoma, non-small cell lung cancer, primary malignant brain tumors, metastatic pancreatic cancer, as well as metastatic prostate cancer.

Class (Stereo):
CHEMICAL (ABSOLUTE)



Pozanicline is an alpha4-beta2 neuronal nicotinic receptor partial agonist. It had been in phase II clinical trials for the treatment of attention hyperactivity disorder and Alzheimer’s disease. It was tested for the treatment of schizophrenia too. All these studies were discontinued. Modulation of hippocampal learning and memory using Pozanicline in animal model was effective as novel therapeutic strategies for nicotine addiction. However future clinical trial was terminated.

Fostedil (KB-944) is a phosphonic acid derivative with potent vasodilator activity. KB-944 has been demonstrated to produce long lasting coronary vasodilator and hypotensive effects in conscious and anesthetized dogs; increase coronary blood flow in isolated, blood perfused heart preparations of dogs; and reduce systemic pressure in conscious normotensive and hypertensive rats. Slow channel calcium entry blockade is thought to contribute to the vasodilator activity of KB-944. Fostedil is longer acting in hypertensive animals than either nifedipine or diltiazem suggesting a potential clinical advantage for this compound. Unexpectedly, fostedil was shown to produce atrial fibrillation in 3 of 10 hypertensive patients in a placebo controlled study. Fostedil had been in phase II clinical trials for the treatment of angina pectoris. However, this research has been discontinued.

Sobetirome (3,5-dimethyl-4[(4'-hydroxy-3'-isopropylbenzyl)-phenoxy] acetic acid, also known as GC-1 and QRX-431, is a member of a class of compounds known as selective thyromimetics. It was firstly developed by Thomas Scanlan’s group at the University of California-San Francisco (UCSF) in 1995. Sobetirome binds selectively to the main hepatic form of thyroid hormone (TH) receptor, TRβ1, compared to TRα1, which is principally responsible for thyrotoxic effects on heart, muscle and bone. Sobetirome also preferentially accumulates in liver. It was originally envisaged that sobetirome could be used to stimulate hepatic pathways that lower cholesterol without harmful side effects and might be used in conjunction with statins. Indeed, sobetirome progressed through preclinical animal studies and Phase I human clinical trials with excellent results and without obvious harmful side effects. Sobetirome had been in phase I clinical trials for the treatment of lipid metabolism disorders and obesity. However, this research has been discontinued.

Sampatrilat (also known as UK 81252) was developed as a dual inhibitor of both angiotensin-converting enzyme (ACE) and neutral endopeptidase (NEP). This drug was studied for the treatment of hypertension and congestive heart failure.
Alvameline is a partial agonist of the M1 mAChR that also displays M2/M3 antagonist effects. It readily crosses the blood-brain barrier. It has an effect profile that makes it of interest to test its ability to counteract bladder overactivity in humans. Behaviorally, alvameline has been shown to significantly improve Morris water maze (MWM) performance in both young and ageimpaired rats. It failed to improve cognition in patients with mild to moderate Alzheimer's disease.
