Tianeptinaline

Tianeptinaline 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 Tianeptinaline rather than just read about it. In short: Tianeptinaline is a histone deacetylase (HDAC) inhibitor which was derived via structural modification of the tricyclic antidepressant (TCA) tianeptine. Pharmacology Tianeptinaline potently inhibits the class I HDAC1, HDAC2, and HDAC3 with IC50Tooltip half-maximal inhibitory concentration values of 240 nM, 120 nM, and 155 nM, whereas it did not inhibit the class II HDAC5 or HDAC6 (IC50 = >80,000 nM).

Key takeaways

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

Reference excerpt

Tianeptinaline is a histone deacetylase (HDAC) inhibitor which was derived via structural modification of the tricyclic antidepressant (TCA) tianeptine.

Pharmacology

Tianeptinaline potently inhibits the class I HDAC1, HDAC2, and HDAC3 with IC50Tooltip half-maximal inhibitory concentration values of 240 nM, 120 nM, and 155 nM, whereas it did not inhibit the class II HDAC5 or HDAC6 (IC50 = >80,000 nM). Potential actions against other HDACs, such as HDAC4, HDAC7, HDAC8, and HDAC9, were not described. The drug has been found to enhance CREB-mediated transcription, penetrate into the brain, and enhance contextual fear conditioning, a behavioral measure of hippocampus-dependent memory, in rodents.

Chemistry The chemical synthesis of tianeptinaline has been described. Another analogue of tianeptinaline, known as tianeptinostat, is also a potent HDAC inhibitor. However, whereas tianeptinaline did not inhibit HDAC6, tianeptinostat was a highly potent inhibitor of HDAC6 in addition to the class I HDACs.

History Tianeptinaline and tianeptinostat were first described in the scientific literature by 2018. They were derived from tianeptine after it was noted that tianeptine has a similar chemical structure to that of the potent clinically used HDAC inhibitor vorinostat (SAHA) and that tianeptine itself is a weak HDAC inhibitor (IC50 = 25,000 nM, 82,000 nM, and >2 mM at HDAC1, HDAC2, and HDAC3, respectively).

Worked examples

Example 1 — a first encounter with Tianeptinaline

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

In research: Tianeptinaline 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 Tianeptinaline 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: Tianeptinaline is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amides, Amines, Chloroarenes, so understanding it makes those chapters shorter.
In everyday life: Look for Tianeptinaline 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.

Why does Tianeptinaline 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 Tianeptinaline?

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.
