LX-5 is a selective activator of the p38 mitogen-activated protein kinase (MAPK) pathway. LX-5 de-represses a subset of endogenous genes repressed by DNA methylation.

Clozapine (HF 1854) is a tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity.

LX-1031 is an effective inhibitor of tryptophan 5-hydroxylase. LX-1031 decreases serotonin (5-HT) synthesis peripherally.
