Epacadostat (INCB024360) is an orally available hydroxyamidine and inhibitor of indoleamine 2,3- dioxygenase (IDO1). It shows little activity against other related enzymes such as IDO2 or tryptophan 2,3-dioxygenase (TDO). Epacadostat displays potential immune modulating and antineoplastic activities. Epacadostat has been tested in phase II and III studies for the treatment of malignant melanoma, fallopian tube cancer, non-small cell lung cancer, ovarian cancer, peritoneal cancer, solid tumors, pancreatic cancer. The most common detected adverse events were fatigue, nausea, decreased appetite, vomiting, constipation, abdominal pain, diarrhea, dyspnea, back pain, and cough.

Ebastine is an antihistamine which blocks H1-receptors through its carboxylic acid metabolite. Ebastine is indicated for the treatment of allergic rhinitis and chronic idiopathic urticaria.

Umirolimus (Biolimus A9), an analogue of sirolimus, is a highly lipophilic macrolide compound developed by Biosensors International as an antiproliferative agent in coronary artery restenosis. Umirolimus has immunosuppressive and anti-inflammatory effects. It is used for the prevention of restenosis.

Etymemazine (RP-6484), a phenothiazine derivative, is a sedative and neuroleptic agent. It is a histamine H₁-receptor antagonist. It was used to treat dementia. It was also used in veterinary.

Ubenimex is a dipeptide, which specificallyinhibits the activity of leukotriene A4 hydrolase, aminopeptidase B and leucine aminopeptidase of the cell membrane. The drug was isolated from Streptomyces oliooreticuli in 1976 in Nippon Kayaku, Japan and approved for the treatment of acute non-lymphocytic leukemia under the name Bestatin. In the USA the drug is currentlu in Phase II for the treatment of pulmonary arterial hypertension and lymphedema.

Tetramisole is a racemic mixture of levamisole and its enantiomer dexamisole, which is a specific inhibitor of tissue non-specific alkaline phosphatase (TNAP). This drug is used in veterinary to treat of ascariasis and other worm infections e.g hook-"ms. And also is used as an immunostimulant (in that case it is used for longer periods of time).

Gusperimus is an antibiotic, isolated from cultures of the soil commensal Bacillus laterosporus. It possess immunosuppressive properties and exerts its effect through binding to heat shock proteins Hsp90 and Hsc70. Although initially, the drug was being investigated for the treatment of cancer, it recieved orphan designation for the treatment of refractory Wegener’s granulomatosis.

Roquinimex (Linomide, LS 2616) is a quinoline-3-carboxamide with pleiotropic immune modulating capacity and it has therapeutic effects in several experimental animal models of autoimmune diseases. Linomide has been evaluated in clinical trials for multiple sclerosis, and was indeed shown to have disease inhibitory effects. However, due to unexpected side effects recorded in patients treated with Linomide, premature termination of clinical trials was required. The basic mechanism(s) of action of Linomide in inducing beneficial effects in autoimmune diseases is still elusive. Some experimental evidence indicates that Linomide influences the regulation of the cytokine profile, resulting in the inhibition of autoimmune and inflammation pathologies. Roquinimex possesses potential antineoplastic activity. Roquinimex inhibits endothelial cell proliferation, migration, and basement membrane invasion; reduces the secretion of the angiogenic factor tumor necrosis factor alpha by tumor-associated macrophages (TAMs); and inhibits angiogenesis. Roquinimex was in phase III clinical trials with Pharmacia Corporation in Europe and the US for the treatment of multiple sclerosis.

Medrylamine is an antihistamine agent. It was used topically. Medrylamine offers sure relief from allergic manifestations of varied and unknown etiologies

Iproheptine (Metron, Susat) is a vasoconstrictor, antihistamine, nasal decongestant marketed in Japan.
