Sarpogrelate

Sarpogrelate 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 Sarpogrelate rather than just read about it. In short: Sarpogrelate (INNTooltip International Nonproprietary Name, JANTooltip Japanese Accepted Name), sold under the brand names Anplag and Sapodifil, is a serotonin 5-HT2 receptor antagonist which is used in the treatment of arterial occlusive disorders such as peripheral artery disease in Japan, South Korea, and China.

Key takeaways

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

Reference excerpt

Sarpogrelate (INNTooltip International Nonproprietary Name, JANTooltip Japanese Accepted Name), sold under the brand names Anplag and Sapodifil, is a serotonin 5-HT2 receptor antagonist which is used in the treatment of arterial occlusive disorders such as peripheral artery disease in Japan, South Korea, and China. Development in the United States and the European Union was discontinued and it is not available in these regions. The drug acts as an antagonist at the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors. However, its affinities for the human 5-HT2C and 5-HT2B receptors are about one and two orders of magnitude lower than for the human 5-HT2A receptor, respectively. The drug blocks serotonin-induced platelet aggregation, and has potential applications in the treatment of many diseases including diabetes mellitus, Buerger's disease, Raynaud's disease, coronary artery disease, angina pectoris, and atherosclerosis. The predicted log P (XLogP3) of sarpogrelate is 1.2. A 2004 review stated that it was unknown whether sarpogrelate crosses the blood–brain barrier. However, other papers have stated that sarpogrelate minimally crosses into the brain and hence is peripherally selective. Accordingly, a rat study found that peak sarpogrelate levels were 50-fold lower in the brain and spinal cord than in the circulation.

Worked examples

Example 1 — a first encounter with Sarpogrelate

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

In research: Sarpogrelate 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 Sarpogrelate 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: Sarpogrelate is common in secondary-school and first-year university syllabi. It links to neighbouring topics 3-Methoxyphenyl compounds, 5-HT2A antagonists, 5-HT2B antagonists, so understanding it makes those chapters shorter.
In everyday life: Look for Sarpogrelate 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 Sarpogrelate in simple terms?

Why does Sarpogrelate 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 Sarpogrelate?

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.
