CPI-0610 is a small molecule inhibitor of the Bromodomain and Extra-Terminal (BET) family of proteins, with potential antineoplastic activity. Upon administration, the BET inhibitor CPI-0610 binds to the acetylated lysine recognition motifs on the bromodomain of BET proteins, thereby preventing the interaction between the BET proteins and acetylated histone peptides. This disrupts chromatin remodeling and gene expression. Prevention of the expression of certain growth-promoting genes may lead to an inhibition of tumor cell growth. CPI-0610 is currently being evaluated in three Phase 1 clinical trials in the U.S.

Biclofibrate was investigated as an antilipidemic agent.

Octamoxine (ximaol), a monoamine oxidase inhibitor was used as an antidepressant to treat mental depression. Now this drug is no longer marketed.

Tezampanel, also known as LY 293558 and NGX-424, is a drug originally developed by Eli Lilly, which is a competitive antagonist of the AMPA and kainate subtypes of the ionotropic glutamate receptor family. Tezampanel was in phase II clinical trial for treatment migraine, but this study was discontinued. Also this drug has several others potential pharmacological actions, one of them is anxiety disorders

PHA-793887 is an inhibitor of multiple cyclin dependent kinases (CDK) with activity against CDK2, CDK1 and CDK4. PHA-793887 was cytotoxic for leukemic cell lines in vitro, with IC(50) ranging from 0.3 to 7 uM. In colony assays PHA-793887 showed very high activity against leukemia cell lines, with an IC(50) <0.1 uM indicating that it has efficient and prolonged antiproliferative activity. PHA-793887 induced cell-cycle arrest, inhibited Rb and nucleophosmin phosphorylation. PHA-793887 has promising therapeutic activity against acute leukemias in vitro and in vivo.

Lidanserin is a drug which acts as a combined 5-HT2A and α1-adrenergic receptor antagonist. In conscious spontaneously hypertensive rats intravenous injection of lidanserin caused dose-dependent blood pressure reductions. Lidanserin antagonises the excitatory effect of synaptically released 5-HT on central sympathoexcitatory neurons. Lidanserin is a potential antihypertensive compound which combines vasodilatatory effects due to selective alpha 1-receptor antagonistic action and platelet antiaggregatory, antivasospastic, and vasoprotective properties due to selective 5-HT2-receptor blockade.

VX-970 (VE-822) is an ATR kinase inhibitor. VE-822 decreased maintenance of cell-cycle checkpoints, increased persistent DNA damage and decreased homologous recombination in irradiated cancer cells. Vertex Pharmaceuticals is developing VX 970 for the treatment of advanced solid tumours. Phase I/II development is underway in the US for small-cell lung cancer and in the UK for solid tumours. Phase II development of VX 970 as a combination therapy in urogenital cancer, ovarian, primary peritoneal and fallopian tube cancer indications is underway in the US.

Bifepramide, (+)- belong to the class of parasympatholytic agents that reduce the activity of the parasympathetic nervous system.
