Sarakalim (previously known as RS 91309) was developed by Roche Bioscience as a putative ATP-sensitive K+ (KATP) channel opener. Sarakalim was studied for the treatment of asthma, However, this study was discontinued.

Furalazine is an antibacterial agent that was studied for the treatment of typical cholera symptoms. However, information about the further development of this drug is not available.

VP-14637 (also known as MDT 637) was developed as an inhibitor of respiratory syncytial virus (RSV). RSV is the leading cause of respiratory tract infections in humans. VP-14637 participated in phase I clinical trial to evaluate the safety and pharmacokinetic profile of the drug in healthy human volunteers. However, further study was discontinued because of the strategic decision.

Apilimod is a small molecule inhibitor of interleukin-12 and interleukin-23 synthesis thereby preventing IL-12/IL-23 mediated immune responses. Apilimod is also observed to inhibit the nuclear accumulation of NF-kappB protein family, and viral infections dependent on phosphatidylinositol-3-phosphate 5-kinase (PIKfyve). Apilimod has been investigated as a potential treatment for a number of autoimmune conditions.

Becocalcidiol is a vitamin D analog participated in phase II clinical trials as a topical treatment for psoriasis. Therapy was safe and well tolerated, however further studies were discontinued.

ISOMYLAMINE is a spasmolytic and smooth muscle relaxant.

FENIODIUM is an anthelmintic agent.

Belaperidone (LU111995) is a recently identified antipsychotic agent with high 5-hydroxytryptamine2 and dopamine D4 receptor affinities as well as D4 versus D2 receptor selectivity. The drug did not produce catalepsy. LU111995 prolongs the Q-T interval to a limited degree and is not arrhythmogenic over the physiological range of cycle lengths. Belaperidone had been in phase II clinical trials for the treatment of schizophrenia. However, the study about this drug candidate was discontinued.

Batanopride, previously known as BMY-25801, a 5-hydroxytryptamine 3 receptor antagonist, was studied against emesis for cancer patients that were treated by chemotherapy procedure. Batanopride had the dose-limiting side effects including hypotension and long QT syndrome that is why any further experiments for its medical application were discontinued.

Avitriptan (BMS-180048), a new 5-HT 1B/1D receptor agonist, has been studied in phase II clinical trials in patients with migraine headaches. Later experiments have confirmed antimigraine activity together with coronary side-effect potential that is why further studies were discontinued.
