Lesopitron is an anxiolytic with pre- and postsynaptic 5-HT1A agonist activity and is more effective than 5-HT1A agonists in rat social interaction and marmoset anxiety models. lesopitron counteracts benzodiazepine withdrawal-induced anxiety in rodents with low acute toxicity and does not potentiate the effects of alcohol or barbiturates.

Enciprazine (D-3112) has anxiolytic activity with high affinity for 5-HT1A receptor and ADRA1, which can be used for the treatment of anxiety disorders and can be used to study depression.

Viloxazine (Viloxazin) 是一种去甲肾上腺素重摄取 (norepinephrine reuptake) 抑制剂，也是有效的 5-HT2C 激动剂和 5-HT2B 拮抗剂，对 5-HT2C 的 EC50 为 32 μM，对 5-HT2B 的 IC50 为 27 μM。Viloxazine 的作用机制主要涉及血清素能和去甲肾上腺素能通路。Viloxazine 可用于抗抑郁研究。
