Juvantia Pharma and Orion developed ORM-12741, also known as ORM-10921, a novel selective antagonist of alpha-2C adrenoceptors for the treatment of depression and Alzheimer's disease. ORM-12741 participated in phase II clinical trial where was evaluated the safety and efficacy of the drug in patients with Alzheimer's disease. In spite of the successfully completed phase II, further study of the drug for this disease was discontinued. In addition, ORM-12741 participated in clinical trial phase II to prove the concept that this drug could prevent blood vessel spasms for Raynaud's phenomenon. Raynaud's phenomenon is a disorder of the digital blood vessels resulting in episodic impairment of blood flow. However, this study was terminated because of the recommendation by study Data and Safety Monitoring Committee to the sponsor following the interim analysis of 8 subjects.

JNJ-39393406 is a positive allosteric alpha-7 nicotinic acetylcholine receptor modulator. It was under development for the treatment of smoking cessation, schizophrenia, Alzheimer's disease, but development for these indications was discontinued.

CHF6001 is a phosphodiesterase 4 (PDE4) inhibitor optimised for inhaled delivery and tolerability, for the treatment of Asthma and Chronic Obstructive Pulmonary Disease. CHF6001 was 7- and 923-fold more potent than roflumilast and cilomilast, respectively, in inhibiting PDE4 enzymatic activity. CHF6001 inhibited PDE4 isoforms A-D with equal potency, showed an elevated ratio of high-affinity rolipram binding site versus low-affinity rolipram binding site and displayed >20,000-fold selectivity versus PDE4 compared with a panel of phosphodiesterases. CHF6001 effectively inhibited the release of tumor necrosis factor-α from human peripheral blood mononuclear cells, human acute monocytic leukemia cell line macrophages (THP-1), and rodent macrophages (RAW264.7 and NR8383). CHF6001 has the potential to be an effective topical treatment of conditions associated with pulmonary inflammation, including asthma and chronic obstructive pulmonary disease.

Saroglitazar, a dual peroxisome proliferator-activated receptor PPAR-α/γ agonist, was an emerging therapeutic option on glycemic and lipid parameters. The Zydus Group has launched LipaglynTM ((Saroglitazar) in India for diabetic dyslipidemia and hypertriglyceridemia with type 2 diabetes mellitus not controlled by statin therapy. In addition, saroglitazar participated in phase II clinical trials that completed enrolment in patients with primary biliary cholangitis and in patients with non-alcoholic steatohepatitis.

Acetorphine is a synthetic narcotic analgesic. Acetorphine was reported to have uses in veterinary medicine with pronounced advantages in the immobilization of the giraffe in which toxic effects were reduced as compared to the effects of etorphine. In July 1966, the Director-General of the World Health Organization informed the Secretary-General that WHO had arrived at the conclusion that etorphine and acetorphine should be included in Schedule I of the Convention, since they could give rise to similar abuse, and produce similar ill effects as the substances already listed therein. Acetorphine is a Schedule I controlled substance in the United States.

Prinaberel is a selective agonist of estrogen receptor beta. Although initially developed for the treatment of endometriosis, the drug was also shown to be effective in vitro in other inflammatory diseases. Phase II clinical studied revealed its effectiveness in case of Crohn's disease and endometriosis, but the drug failed to demonstrate antiinflammatory efficacy in RA patients.
