Salethamide was developed as an anti-inflammatory agent to use as an analgesic. However, information about the further study of this compound is not available.

Levdobutamine is a beta-adrenoceptor agonist selective for the beta1-subtype. Levdobutamine was derived from dopamine. It is the active (S)-isomer of dobutamine. It is the cardiotonic agent.

Tigestol is an Estrene derivative patented by Organon Laboratories Ltd. as an anabolic, androgenic, and progestative agent.

Octazamide an analgesic that was studied as an anti-inflammatory agent. Information about the current development of this compound is not available.

Ensaculin is related to naturally occurring benzopyranones like scoparone. The compound is a potent functional antagonist of excitatory amino acid-induced convulsions and mortality. In receptor-binding studies, Ensaculin showed high affinity to dopaminergic (D2, D3), serotoninergic (5-HT1A, 5-HT7), and adrenergic (A1a, A1b) receptors in the nanomolar range. Ensaculin antagonizes NMDA responses in a voltage-dependent manner. Various studies support the notion that this compound could indeed have a broad range of nootropic properties. Although few patients presented postural hypotension and dizziness after receiving ensaculin in phase I clinical trials, this drug candidate was further discontinued in phase III due to potential side effects.

Etazepine (5,6-dihydro-5-methyl-11H-11-ethoxy-dibenzo[b,e]azepin-6-one) demonstrates anticonvulsant activity in rodents. Etazepine seems to exert its anticonvulsant effects by activating the GABAergic system.

Oxiperomide was developed as a dopamine-receptor antagonist. Clinical trials have shown that this drug decreased dyskinesia in patients with Parkinson's disease receiving levodopa or other dopamine agonists without necessarily increasing Parkinsonian symptoms. However, information about the further development of this drug is not available.

Vinpoline was studied as a central stimulant. Information about the further development of this agent is not available.

Melizame is a sugar substitute for sweetening caloric or noncaloric materials.
