XOB, also known as ASR-6001 or as N-[(4-phenylbutoxy)hexyl]-4-bromo-2,5-dimethoxyphenethylamine, is a serotonin 5-HT2A receptor antagonist and voltage-gated sodium channel (VGSC) blocker of the phenethylamine and 2C families.[1] It is a derivative of 2C-B in which the amine-containing side chain has been extended with the same long group found in salmeterol.[1]

The drug is of relatively low potency as a serotonin 5-HT2A receptor antagonist.[1] It shows modest selectivity for the serotonin 5-HT2A receptor over the serotonin 5-HT2B and 5-HT2C receptors.[1] XOB was accidentally found to have local anesthetic properties upon contact with human skin, which led to the elucidation of its sodium channel-blocking activity.[1]

XOB was developed in part by researchers at the Alexander Shulgin Research Institute (ASRI).[1]
