(S) -Laudanosine

(S) -Laudanosine is an alkaloid that can be found in poppies and is the S-enantiomer of Laudanosine. Laudanosine acts on the central nervous system and cardiovascular system, inhibiting low-affinity GABA receptors with an IC50 value of 10 μM, and can cause seizures, hypotension, and bradycardia. Additionally, Laudanosine exerts analgesic effects by competitively binding to the opioid Mu-1 receptor (Ki = 2.7 μM) [1][2][3][4].
