SB-431542

SB-431542 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 SB-431542 rather than just read about it. In short: SB-431542 is a drug candidate developed by GlaxoSmithKline (GSK) as an inhibitor of the activin receptor-like kinase (ALK) receptors, ALK5, ALK4 and ALK7. However, it is not an inhibitor of anaplastic lymphoma kinase (which are commonly known as ALK inhibitors).

Key takeaways

SB-431542 belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SB-431542 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SB-431542 from memory before moving on to harder problems.

Reference excerpt

SB-431542 is a drug candidate developed by GlaxoSmithKline (GSK) as an inhibitor of the activin receptor-like kinase (ALK) receptors, ALK5, ALK4 and ALK7. However, it is not an inhibitor of anaplastic lymphoma kinase (which are commonly known as ALK inhibitors).

In-vitro studies While SB-431542 has not proved directly useful for any clinical application, it is used for several applications in molecular biology. It suppresses the TGF-beta-induced proliferation of osteosarcoma cells in humans. SB431542 can also be used in combination with LDN193189, CHIR99021 and DAPT to transform astrocytes into neurons. It is also commonly used for immunological studies, for instance as a TGF-β inhibitor to facilitate the generation of dendritic cells from peripheral blood monocytes.

Worked examples

Example 1 — a first encounter with SB-431542

Start with the simplest possible case. Write down what SB-431542 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 SB-431542 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 SB-431542 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 SB-431542

In research: SB-431542 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 SB-431542 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: SB-431542 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2-Pyridyl compounds, Carboxamides, Drugs developed by GSK plc, so understanding it makes those chapters shorter.
In everyday life: Look for SB-431542 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.
