LA-MeO

LA-MeO 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 LA-MeO rather than just read about it. In short: LA-MeO, also known as lysergic acid ethyl-2-methoxyethylamide or as N-ethyl-N-(2-methoxyethyl)lysergamide, is a serotonin receptor modulator of the lysergamide family related to lysergic acid diethylamide (LSD). It is the O-methyl ether derivative of the LSD metabolite lysergic acid ethyl-2-hydroxyethylamide (LEO).

Key takeaways

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

Reference excerpt

LA-MeO, also known as lysergic acid ethyl-2-methoxyethylamide or as N-ethyl-N-(2-methoxyethyl)lysergamide, is a serotonin receptor modulator of the lysergamide family related to lysergic acid diethylamide (LSD). It is the O-methyl ether derivative of the LSD metabolite lysergic acid ethyl-2-hydroxyethylamide (LEO). The drug shows high affinity for the serotonin 5-HT1A, 5-HT2A, and 5-HT2C receptors (Ki = 4.0 nM, 7.1 nM, and 7.8 nM, respectively). It acts as a potent partial agonist of the serotonin 5-HT2A receptor similarly to LSD, with an EC50Tooltip half-maximal effective concentration of 30.3 nM and an EmaxTooltip maximal efficacy of 29.6% (relative to 8.4 nM and 22.4% in the case of LSD, respectively). LA-MeO was first described in the scientific literature by Jason C. Parrish of the lab of David E. Nichols at Purdue University by 2007.

Worked examples

Example 1 — a first encounter with LA-MeO

Start with the simplest possible case. Write down what LA-MeO 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 LA-MeO 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 LA-MeO 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 LA-MeO

In research: LA-MeO 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 LA-MeO 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: LA-MeO is common in secondary-school and first-year university syllabi. It links to neighbouring topics 5-HT2A agonists, Carboxamides, Diethylamino compounds, so understanding it makes those chapters shorter.
In everyday life: Look for LA-MeO 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 LA-MeO in simple terms?

Why does LA-MeO 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 LA-MeO?

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.
