Lysergamides

Lysergamides is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lysergamides rather than just read about it. In short: Lysergamides, also known as ergoamides or as lysergic acid amides, are amides of lysergic acid (LA). They are ergolines, with some lysergamides being found naturally in ergot as well as other fungi.

Key takeaways

  • Lysergamides belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Lysergamides to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Lysergamides from memory before moving on to harder problems.

Reference excerpt

Lysergamides, also known as ergoamides or as lysergic acid amides, are amides of lysergic acid (LA). They are ergolines, with some lysergamides being found naturally in ergot as well as other fungi. Lysergamides are notable in containing embedded phenethylamine and tryptamine moieties within their ergoline ring system. The simplest lysergamides are ergine (lysergic acid amide; LSA) and isoergine (iso-lysergic acid amide; iso-LSA). In terms of pharmacology, the lysergamides include numerous serotonin and dopamine receptor agonists, most notably the psychedelic drug lysergic acid diethylamide (LSD) but also a number of pharmaceutical drugs like ergometrine, methylergometrine, methysergide, and cabergoline. Various analogues of LSD, such as the psychedelics ALD-52 (1A-LSD), ETH-LAD, LSZ, and 1P-LSD and the non-hallucinogenic 2-bromo-LSD (BOL-148), have also been developed. Ergopeptines like ergotamine, dihydroergotamine, and bromocriptine are also lysergamides, but with addition of a small peptide moiety at the amide. Close analogues of lysergamides that are not technically lysergamides themselves include lisuride, terguride, bromerguride, and JRT. Lysergamides were first discovered and described in the 1930s. Simplified or partial ergolines and lysergamides, such as NDTDI (8,10-seco-LSD), DEMPDHPCA, and N-DEAOP-NMT, are also known.

Use and effects The doses, potencies, durations, and effects of lysergamides have been reviewed by Alexander Shulgin. They have also been reviewed by Albert Hofmann, David E. Nichols, and other researchers.

The properties of various additional lysergamides, for instance in terms of serotonin antagonism, have also been described.

History

Lysergamides, such as ergine, isoergine, and ergometrine, were discovered by the early 1930s, and LSD was discovered by 1938 and its hallucinogenic effects in 1943 by Albert Hofmann. Many synthetic lysergamide analogues of LSD, modified at the amide and/or 1 or 2 positions, were first described by Hofmann and colleagues in the mid-to-late 1950s. N(6)-Substituted lysergamides were first reported in 1970 and thereafter in the 1970s and 1980s by multiple groups, including Hofmann and colleagues, Yuji Nakahara and Tetsukichi Niwaguchi and colleagues, and David E. Nichols and colleagues. The psychedelic effects of N(6)-substituted lysergamides were reported by Alexander Shulgin in 1986 and thereafter. Additional novel lysergamides modified at the amide, like LA-3Cl-SB and LA-Aziridine, were described by Nichols and Robert Oberlender and colleagues in the late 1980s, while LSZ (LA-Azetidine) was described by the same group in 2002. Numerous 1-substituted LSD prodrugs such as 1P-LSD and 1V-LSD and other psychedelic lysergamides were developed by Lizard Labs in the 2010s and 2020s.

Worked examples

Example 1 — a first encounter with Lysergamides

Start with the simplest possible case. Write down what Lysergamides claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lysergamides before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lysergamides ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lysergamides

In research
Lysergamides appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Lysergamides in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Lysergamides is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alkaloids, Chemical classes of psychoactive drugs, Lysergamides, so understanding it makes those chapters shorter.
In everyday life
Look for Lysergamides outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Lysergamides in simple terms?

Lysergamides, also known as ergoamides or as lysergic acid amides, are amides of lysergic acid (LA). They are ergolines, with some lysergamides being found naturally in ergot as well as other fungi.

Why does Lysergamides matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lysergamides?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Lysergamides.
