ALD-52
ALD-52 (1-Acetyl-LSD) is a prodrug for LSD. ALD-52 shows an affinity to 5-HT1A, 5-HT2A and 5-HT2C with a sub>D values of 1054, 174 and 10.2 nM, respectively. ALD-52 is converted to LSD and induces a head-twitch response (HTR) in vivo. ALD-52 can be used for hallucinogen research.

Biological Activity
ALD-52 shows an affinity to 5-HT1A, 5-HT2A and 5-HT2C with a sub>D values of 1054, 174 and 10.2 nM, respectively[1].
ALD-52 acts as very weak partial agonists at the human 5-HT2A receptor with an EC50 value of 38 nM and an Emax value of 25%, shows slightly higher potency and efficacy at m5-HT2A< /sub> with an EC50 value of 12 nM and an Emax value of 19%, shows no agonist activity at h5-HT2B and h5-HT2C in HEK cell[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
ALD-52 (0.1-0.3 mg/kg, s.c., once) produces LSD plasma concentrations of 35.5 and 103.8 ng/mL in Sprague Dawley rats, respectively[1].
ALD-52 (0.3 mg/kg, s.c., once) has biotransformation with multipathway and does not simply involve complete conversion to LSD (undergoes N deethylation, N6 demethylation, and hydroxylation, yielding two phenolic metabolites) in Sprague Dawley rats (consistent results were obtained using the in vitro human liver homogenate system.)[1].
