Sodium aceneuramate is a sodium salt of aceneuramic acid (sialic acid). It is an effective inhalant expectorant. Inhalation of sodium aceneuramate repaired inflammation in the airway, and caused bronchitic rabbits to produce sputa with a low viscosity, similar to normal air-way secretions. Sodium aceneuramate protected the mucociliary transport impaired bycigarette smoke in a dose-dependent manner. The results suggest that sodium aceneuramate may participate in the defense mechanism in the airway against irritant gases. Sodium aceneuramate inhibited bronchial anaphylaxis and the release of histamine into bronchoalveolar lavages. Sodium aceneuramate has an action which elevates the viscoelasticity of secretions in the respiratory tract.

METHYLENETETRAHYDROFOLIC ACID, L-(+), an endogenous biomodulator that was developed under the brand name modufolin or arfolitixorin by the Isofol Medical. Arfolitixorin is developed to increase the efficacy of standard of care chemotherapy for advanced colorectal cancer. This drug is currently being studied in a global phase 3 clinical trial. Besides, the drug successfully completed phase II as rescue therapy for osteosarcoma. 21 May 2019 Isofol Medical has received clinical patent protection for the arfolitixorinin USA. It relates to a method of increasing blood concentration of deoxyuridine, a blood biomarker for inhibition of tumor growth in human cancer treatment.

9cUAB30 is a synthetic analog of 9-cis-RA with little or no RAR-binding activity relative to 9-cis-RA and other RA. 9cUAB30, is a selective rexinoid for the retinoid X nuclear receptors (RXR). Retinoid 9cUAB30 binds to and activates retinoid X receptor (RXR) homodimers and/or and retinoic acid receptor (RAR)/RXR heterodimers, which may result in the dissociation of corepressor protein and the recruitment of coactivator protein, followed by transcription of downstream target genes into mRNAs and protein translation. Gene transcription regulated by these transcription factors may result in inhibition of cell proliferation, induction of cell differentiation, and apoptosis of both normal cells and tumor cells. 9cUAB30 displays substantial chemopreventive capacity with little toxicity and is being translated to the clinic as a novel cancer prevention agent. 9cUAB30 has been assessed in vitro with human cell cultures. Human hepatocytes demonstrated no signs of cytotoxicity with treatment of 9cUAB30 up to 50 umol/L, although when human breast cancer cells were treated with 9cUAB30, they showed a significant inhibition of cell proliferation and apoptotic levels 2.5to 3.5 times the levels of untreated cells. 9cUAB30 inhibits telomerase and induces apoptosis in HL60 cells.

Chlorpromazine Phenolphthalinate is Phenolphthalinate salt of psychotropic agent Chlorpromazine marketed as Wintermin by Japanese pharmaceutical company Shionogi Inc for treating certain mental or mood disorders. Chlorpromazine is a psychotropic agent indicated for the treatment of schizophrenia and other central nervous system disease

Piridronic acid is pyridinyl bisphosphonate. It is the bone calcium metabolism regulator. Piridronic acid was used for the treatment of osteoporosis. It is the human farnesyl pyrophosphate synthase inhibitor. When expressed on an actual or anticipated clinical dose basis for osteoporosis piridronic acid may have a greater potential for inducing gastric damage than do pyridinyl bisphosphonates. Piridronic acid induced significantly more antral damage than risedronate and a greater number of lesions compared to pamidronate and risedronate.

Premafloxacin is an 8-methoxy fluoroquinolone derivative patented by American pharmaceutical company Warner-Lambert Co. as an antibacterial agent. In preclinical studied. Premafloxacin was equivalent to ciprofloxacin, enrofloxacin, and danofloxacin in activity against the gram-negative bacilli but was much more active than the comparison antimicrobial agents (against the staphylococci, streptococci, and anaerobes. Premafloxacin acts as a topoisomerase IV inhibitor with enhanced activity against Staphylococcus aureus.

Deferitrin is a desferrithiocin-derived hexadentate iron chelator, developed by Genzyme Corp. for the treatment of severe iron overload in people who require repeated erythrocyte transfusion for the management of chronic anemia such as beta-thalassemia major. Development of the drug was halted after phase 1/2 clinical trial due to nephrotoxicity.

Aftobetin, also known as ANCA11 and NCE-11, is a novel amyloid–binding compound applied topically in the form of an ophthalmic ointment. Aftobetin offers a promising way for a noninvasive eye-scan to diagnose Alzheimer’s disease early.

Ore Pharmaceuticals developed ORE1001 previously known as MLN-4760 as an orally administered, small molecule compound, for the treatment of inflammatory bowel diseases. ORE1001 is a specific angiotensin-converting enzyme 2 inhibitor. It was shown that ORE1001 markedly decreased tissue myeloperoxidase activity, a well-known marker of inflammation. As a result, ORE1001 was studied as a treatment of gastrointestinal inflammatory conditions. ORE1001 was involved in phase I clinical trial to investigate its safety and activity in subjects with ulcerative colitis. In addition, the drug was studied for NSAID-induced ulcer and obesity. However, all these studies were discontinued.
