6,7-Dehydrohyoscyamine (6,7DHHA) is a synthetic alkaloid that is produced by the dehydration of hyoscyamine. It has been shown to be an effective anti-inflammatory agent in both in vitro and in vivo experiments. 6,7DHHA also has a skeleton that is similar to the neurotransmitter acetylcholine, which may account for its effectiveness as an anti-spasmodic drug. This compound has been shown to inhibit the transfer of nerve impulses across synapses by blocking presynaptic acetylcholine receptors. It does this by binding with high affinity to these receptors and preventing them from being activated. 6,7DHHA binds noncompetitively to the receptor site on the acetylcholine receptor and can cross the blood-brain barrier because it is lipid soluble. The biosynthesis of 6,7DHHA starts with two molecules of L-phenylalanine condensed together with one molecule of L-
