Pracinostat

Pracinostat 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 Pracinostat rather than just read about it. In short: Pracinostat (SB939) is an orally bioavailable, small-molecule histone deacetylase (HDAC) inhibitor based on hydroxamic acid with potential anti-tumor activity characterized by favorable physicochemical, pharmaceutical, and pharmacokinetic properties. Activity Pracinostat selectively inhibits HDAC class I, II, IV without class III and HDAC6 in class IIb, but has no effect on other Zn-binding enzymes, receptors, and i…

Key takeaways

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

Reference excerpt

Pracinostat (SB939) is an orally bioavailable, small-molecule histone deacetylase (HDAC) inhibitor based on hydroxamic acid with potential anti-tumor activity characterized by favorable physicochemical, pharmaceutical, and pharmacokinetic properties.

Activity Pracinostat selectively inhibits HDAC class I, II, IV without class III and HDAC6 in class IIb, but has no effect on other Zn-binding enzymes, receptors, and ion channels. It accumulates in tumor cells and exerts a continuous inhibition to histone deacetylase, resulting in acetylated histones accumulation, chromatin remodeling, tumor suppressor genes transcription, and ultimately, apoptosis of tumor cells.

Clinical medication Clinical studies suggests that pracinostat has potential best pharmacokinetic properties when compared to other oral HDAC inhibitors. In March 2014, pracinostat has granted Orphan Drug for acute myelocytic leukemia (AML) and for the treatment of T-cell lymphoma by the Food and Drug Administration.

Worked examples

Example 1 — a first encounter with Pracinostat

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

In research: Pracinostat 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 Pracinostat 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: Pracinostat is common in secondary-school and first-year university syllabi. It links to neighbouring topics Benzimidazoles, Diethylamino compounds, Histone deacetylase inhibitors, so understanding it makes those chapters shorter.
In everyday life: Look for Pracinostat 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 Pracinostat in simple terms?

Why does Pracinostat 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 Pracinostat?

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 Pracinostat.
