FLOTEGATIDE F-18, a radiolabelled tripeptide with arginine-glycine-aspartic acid (R-G-D) motif, is a positron emission tomography (PET) tracer targeting integrin alpha-V/beta-3. It was under development as a diagnostic agent for cancer and atherosclerosis.

ATB-346, being developed by Antibe Therapeutics, a Toronto-based pharmaceutical company, is a hydrogen sulfide-releasing non-steroidal anti-inflammatory drug (NSAID) that inhibits COX and suppresses prostaglandin production. ATB-346 exhibits anti-inflammatory, analgesic, antinociceptive, immunomodulatory, and neuroprotective activities. In vivo, this compound attenuates zymosan-induced inflammation, nociception, and immune signaling. ATB-346 also prevents ligature-induced periodontal bone loss and pathologies, potentially by suppressing increases in pro-inflammatory cytokine levels. Additionally, ATB-346 decreases edema and improves neurological function in animal models of traumatic brain injury (TBI). ATB-346 completed Phase 1 clinical studies in Q1 2015. To better understand the metabolism of ATB-346, Antibe conducted a radiolabeled study in rats at Covance Laboratories that was completed in Q4 2015. Antibe received approval from Health Canada in March 2016 to conduct a Phase 2 trial of ATB-346 in patients with osteoarthritis of the knee. Preclinical studies of ATB-346 for the treatment intestinal cancer; malignant melanoma; periodontal disorders are in progress.

DL-Kynurenine is a racemic mixture of D-kynurenine and L-kynurenine. Kynurenine is the precursor of kynurenic acid, an endogenous antagonist of the glycine site of the NMDA (N-methyl-D-aspartate) receptor. Kynurenine has been identified as an endogenous ligand of the aryl hydrocarbon receptor (AhR), a receptor known to be activated by various environmental toxicants, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).

PF-477736 is a selective, potent and ATP-competitive Chk1 inhibitor. Compound was tested in combination with gembcitabine in phase I clinical trials in patients with advanced solid tumors.

Metindizate was developed as a spasmolytic agent. Information about the current use of this compound is not available.

Theophylline ephedrine is a pharmacologically active salt useful for the treatment of obstructive ventilatory disorders. Theophylline / Ephedrine is used for Wheezing, Shortness of breath, Chest tightness, Interruption of breathing in newborns, Mild and chronic bronchial asthma, Low blood pressure and other conditions.

Empesertib (previously known as BAY-1161909) was developed as a selective inhibitor of the serine/threonine monopolar spindle 1 (Mps1) kinase for the treatment of cancer. Empesertib participated in phase I clinical trials in combination with paclitaxel in subjects with advanced malignancies. The studies were terminated because another more successful Mps1 inhibitor was being developed in parallel.

Milataxel, a taxane that binds to and stabilizes tubulin, resulting in the inhibition of microtubule depolymerization. Milataxel has completed phase II clinical trials for non-small cell lung cancer patients, and for colorectal cancer patients. Besides, it was studied for malignant mesothelioma. However, the drug has been discontinued due to toxicity issues at the dose level of 35 mg/m 2.
