MRZ-9547

MRZ-9547 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 MRZ-9547 rather than just read about it. In short: MRZ-9547, also known as (R)-phenylpiracetam, (R)-phenotropil, or (R)-fonturacetam, is a selective dopamine reuptake inhibitor (IC50Tooltip half-maximal inhibitory concentration = 14.5 μM) that was developed by Merz Pharma. It is the (R)-enantiomer of the racetam and nootropic phenylpiracetam (phenotropil; fonturacetam).

Key takeaways

MRZ-9547 belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect MRZ-9547 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of MRZ-9547 from memory before moving on to harder problems.

Reference excerpt

MRZ-9547, also known as (R)-phenylpiracetam, (R)-phenotropil, or (R)-fonturacetam, is a selective dopamine reuptake inhibitor (IC50Tooltip half-maximal inhibitory concentration = 14.5 μM) that was developed by Merz Pharma. It is the (R)-enantiomer of the racetam and nootropic phenylpiracetam (phenotropil; fonturacetam). The drug was under development for the treatment of fatigue associated with Parkinson's disease and was in phase 1 clinical trials for this indication in June 2014. However, no recent development has been reported as of November 2017. There was also interest in MRZ-9547 for treatment of fatigue in people with depression and other conditions, but this was not pursued. Similarly to other dopamine reuptake inhibitors and related agents, MRZ-9547 has been found to have pro-motivational effects in animals and to reverse motivational deficits induced by the dopamine depleting agent tetrabenazine. The drug, as the enantiopure (R)-enantiomer of phenylpiracetam, was first described in the scientific literature by 2014.

Worked examples

Example 1 — a first encounter with MRZ-9547

Start with the simplest possible case. Write down what MRZ-9547 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 MRZ-9547 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 MRZ-9547 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 MRZ-9547

In research: MRZ-9547 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 MRZ-9547 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: MRZ-9547 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Abandoned drugs, Acetamides, Dopamine reuptake inhibitors, so understanding it makes those chapters shorter.
In everyday life: Look for MRZ-9547 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.
