Lophophine

Lophophine is a science 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 Lophophine rather than just read about it. In short: Lophophine, also known as 2C-MMDA-1, 5-methoxy-MDPEA, or 3-methoxy-4,5-methylenedioxyphenethylamine (MMDPEA or MMDPEA-1), is a psychedelic drug of the methylenedioxyphenethylamine family. It is the α-demethylated homologue of MMDA, and is also closely related to mescaline (3,4,5-trimethoxyphenethylamine) and MDPEA.

Key takeaways

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

Reference excerpt

Lophophine, also known as 2C-MMDA-1, 5-methoxy-MDPEA, or 3-methoxy-4,5-methylenedioxyphenethylamine (MMDPEA or MMDPEA-1), is a psychedelic drug of the methylenedioxyphenethylamine family. It is the α-demethylated homologue of MMDA, and is also closely related to mescaline (3,4,5-trimethoxyphenethylamine) and MDPEA. Lophophine has been encountered as a novel designer drug.

Use and effects Alexander Shulgin reported in PiHKAL (Phenethylamines I Have Known and Loved) and other publications that lophophine is active in the dose range of 150 to 250 mg orally. He states that at these doses, lophophine has some similarity to mescaline in action, in producing a peaceful elevation of mood, euphoria, and mild enhancement of visual perception, but without the generation of closed-eye mental imagery. Shulgin also notes that, in contrast to mescaline, lophophine causes no nausea. He estimated that it was about twice the potency of mescaline.

Interactions

Chemistry Lophophine, also known as 3-methoxy-4,5-methylenedioxyphenethylamine, is a phenethylamine and methylenedioxyphenethylamine (MDxx) derivative.

Synthesis The chemical synthesis of lophophine has been described.

Analogues Analogues of lophophine (5-methoxy-MDPEA or 2C-MMDA-1) include mescaline (3,4,5-trimethoxyphenethylamine), 3,4-methylenedioxyphenethylamine (MDPEA), 2C-MMDA-2 (MMDPEA-2), 2C-MMDA-3a (MMDPEA-3a), and MMDA (5-methoxy-MDA), among others.

Natural occurrence Alexander Shulgin originally suggested that lophophine may be a natural constituent of peyote (Lophophora williamsii) due to it being the only logical chemical intermediate for the biosynthesis of several tetrahydroisoquinolines known to be present in this cactus species. Subsequently, lophophine was indeed shown to be a minor component of both peyote and San Pedro cactus.

History Lophophine was encountered as a novel designer drug in Europe in 2023.

Society and culture

Legal status

Canada Lophophine is controlled substance in Canada under phenethylamine blanket-ban language.

United States Lophophine is not an explicitly controlled substance in the United States. However, it could be considered a controlled substance under the Federal Analogue Act if intended for human consumption.

Worked examples

Example 1 — a first encounter with Lophophine

Start with the simplest possible case. Write down what Lophophine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Lophophine 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 Lophophine 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 Lophophine

In research: Lophophine appears in science 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 Lophophine 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: Lophophine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Designer drugs, Drugs not assigned an ATC code, Lophophora alkaloids, so understanding it makes those chapters shorter.
In everyday life: Look for Lophophine 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 Lophophine in simple terms?

Why does Lophophine matter?

Because it connects several science 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 Lophophine?

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.
