JNJ-26146900

JNJ-26146900 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 JNJ-26146900 rather than just read about it. In short: JNJ-26146900 is a selective androgen receptor modulator (SARM) which was developed by Johnson & Johnson for the potential treatment of prostate cancer but was never marketed. Description The drug is a nonsteroidal androgen receptor (AR) modulator with mixed agonistic (androgenic) and antagonistic (antiandrogenic) effects.

Key takeaways

JNJ-26146900 belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect JNJ-26146900 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of JNJ-26146900 from memory before moving on to harder problems.

Reference excerpt

JNJ-26146900 is a selective androgen receptor modulator (SARM) which was developed by Johnson & Johnson for the potential treatment of prostate cancer but was never marketed.

Description The drug is a nonsteroidal androgen receptor (AR) modulator with mixed agonistic (androgenic) and antagonistic (antiandrogenic) effects. In animals, it partially prevents castration-induced loss of body weight, lean body mass (LBM), and bone (osteopenia or osteoporosis) and reduces prostate weight and prostate tumor growth. The nonsteroidal antiandrogen bicalutamide was also effective in partially preventing castration-induced loss of body weight and lean body mass, suggesting that it too may have some SARM-like activity in certain tissues. However, neither JNJ-26146900 nor bicalutamide were as effective as dihydrotestosterone (DHT) in terms of these effects. Based on the preceding findings, JNJ-26146900 shows a profile of androgenic and anabolic effects in muscle and bone but antiandrogenic effects in the prostate. The drug is a novel indole derivative SARM and is structurally related to JNJ-37654032. JNJ-26146900 did not advance past the preclinical research and was never tested in humans. It was first described in the scientific literature by 2007.

Worked examples

Example 1 — a first encounter with JNJ-26146900

Start with the simplest possible case. Write down what JNJ-26146900 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 JNJ-26146900 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 JNJ-26146900 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 JNJ-26146900

In research: JNJ-26146900 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 JNJ-26146900 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: JNJ-26146900 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Abandoned drugs, Esyl compounds, Experimental sex-hormone agents, so understanding it makes those chapters shorter.
In everyday life: Look for JNJ-26146900 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.
