S 38093 is primarily investigated for its potential in neurological research, particularly as a compound with activity affecting neurotransmitter systems. It has been studied for its role as a histamine H3 receptor antagonist or inverse agonist, which suggests utility in modulating cognitive functions such as attention, wakefulness, and memory. Due to this mechanism, it has been explored in preclinical models for conditions like narcolepsy, attention deficit disorders, and other cognitive impairments associated with neurodegenerative diseases. Its ability to enhance histaminergic transmission may also contribute to antidepressant and anxiolytic-like effects observed in animal studies. While not marketed for clinical use, S 38093 serves as a valuable pharmacological tool in understanding central nervous system pathways and in the development of novel therapeutics targeting sleep-wake regulation and cognitive enhancement.
