RU-59063

RU-59063 is a science 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 RU-59063 rather than just read about it. In short: RU-59063 is a nonsteroidal androgen or selective androgen receptor modulator (SARM) which was first described in 1994 and was never marketed. It was originally thought to be a potent antiandrogen, but subsequent research found that it actually possesses dose-dependent androgenic activity, albeit with lower efficacy than dihydrotestosterone (DHT).

Key takeaways

RU-59063 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect RU-59063 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of RU-59063 from memory before moving on to harder problems.

Reference excerpt

RU-59063 is a nonsteroidal androgen or selective androgen receptor modulator (SARM) which was first described in 1994 and was never marketed. It was originally thought to be a potent antiandrogen, but subsequent research found that it actually possesses dose-dependent androgenic activity, albeit with lower efficacy than dihydrotestosterone (DHT). The drug is an N-substituted arylthiohydantoin and was derived from the first-generation nonsteroidal antiandrogen (NSAA) nilutamide. The second-generation NSAAs enzalutamide, RD-162, and apalutamide were derived from RU-59063. RU-59063 has a high affinity for the human androgen receptor (AR) (Ki = 2.2 nM; Ka = 5.4 nM) and 1,000-fold selectivity for the AR over other nuclear steroid hormone receptors, including the PRTooltip progesterone receptor, ERTooltip estrogen receptor, GRTooltip glucocorticoid receptor, and MRTooltip mineralocorticoid receptor. It shows 3- and 8-fold higher affinity than testosterone for the rat and human AR, respectively, and up to 100-fold higher affinity for the rat AR than the first-generation NSAAs flutamide, nilutamide, and bicalutamide. It also has a slightly higher affinity for the AR than DHT and nearly equal affinity to that of the very-high-affinity AR ligand metribolone (R-1881). In addition, RU-59063, unlike testosterone and DHT, shows no specific binding to human plasma.

Worked examples

Example 1 — a first encounter with RU-59063

Start with the simplest possible case. Write down what RU-59063 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 RU-59063 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 RU-59063 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 RU-59063

In research: RU-59063 appears in science 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 RU-59063 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: RU-59063 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2-(Trifluoromethyl)benzonitriles, Abandoned drugs, Primary alcohols, so understanding it makes those chapters shorter.
In everyday life: Look for RU-59063 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.
