Rogletimide

Rogletimide 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 Rogletimide rather than just read about it. In short: Rogletimide, also known as pyridoglutethimide, is a medication which was never marketed. It is related in chemical structure to the sedative/hypnotic drug glutethimide, but instead has pharmacological activity as a selective aromatase inhibitor similar to the related drug aminoglutethimide and has no significant sedative-hypnotic effect.

Key takeaways

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

Reference excerpt

Rogletimide, also known as pyridoglutethimide, is a medication which was never marketed. It is related in chemical structure to the sedative/hypnotic drug glutethimide, but instead has pharmacological activity as a selective aromatase inhibitor similar to the related drug aminoglutethimide and has no significant sedative-hypnotic effect. This makes it potentially useful in the treatment of breast cancer, and with fewer side effects than aminoglutethimide, but its lower potency caused it to be unsuccessful in clinical trials.

Synthesis

Base catalyzed alkylation of ethyl 4-pyridylacetate [54401-85-3] (1) with iodoethane gives ethyl 2-(4-pyridyl)butyrate [76766-56-8] (2). Base catalyzed conjugate addition of the carbanion to acrylamide (3) gives (4). The last step is an intramolecular cyclization to rogletimide (5).

Worked examples

Example 1 — a first encounter with Rogletimide

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

In research: Rogletimide 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 Rogletimide 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: Rogletimide is common in secondary-school and first-year university syllabi. It links to neighbouring topics 4-Pyridyl compounds, Abandoned drugs, Antineoplastic and immunomodulating drug stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Rogletimide 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 Rogletimide in simple terms?

Why does Rogletimide 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 Rogletimide?

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.
