Indoprofen

Indoprofen 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 Indoprofen rather than just read about it. In short: Indoprofen is a nonsteroidal anti-inflammatory drug (NSAID). It was withdrawn worldwide in the 1980s after postmarketing reports of severe gastrointestinal bleeding.

Key takeaways

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

Reference excerpt

Indoprofen is a nonsteroidal anti-inflammatory drug (NSAID). It was withdrawn worldwide in the 1980s after postmarketing reports of severe gastrointestinal bleeding. A 2004 study using high-throughput screening found indoprofen to increase production of the survival of motor neuron protein, suggesting it may provide insight into treatments for spinal muscular atrophies.

Synthesis The isoindolone ring system forms the nucleus for this profen NSAID.

The nitro group in 2-(4-nitrophenyl)propionic acid (1) is reduced using iron and hydrochloric acid to give 2-(4-aminophenyl)propionic acid (2). Reaction with phthalic anhydride then gives the phthalimide (4). Treatment with zinc in acetic acid yields indoprofen after reduction of one of the amide groups.

Worked examples

Example 1 — a first encounter with Indoprofen

Start with the simplest possible case. Write down what Indoprofen 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 Indoprofen 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 Indoprofen 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 Indoprofen

In research: Indoprofen 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 Indoprofen 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: Indoprofen is common in secondary-school and first-year university syllabi. It links to neighbouring topics Isoindolines, Lactams, Musculoskeletal system drug stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Indoprofen 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 Indoprofen in simple terms?

Indoprofen is a nonsteroidal anti-inflammatory drug (NSAID). It was withdrawn worldwide in the 1980s after postmarketing reports of severe gastrointestinal bleeding.

Why does Indoprofen 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 Indoprofen?

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 Indoprofen.
