UCD0168

UCD0168 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 UCD0168 rather than just read about it. In short: UCD0168 is a serotonin releasing agent (SRA) of the tropane family related to the tryptamines. It is potent, selective, and shows full efficacy as an SRA in serotonin transporter (SERT)-transfected HEK293T cells.

Key takeaways

UCD0168 belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect UCD0168 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of UCD0168 from memory before moving on to harder problems.

Reference excerpt

UCD0168 is a serotonin releasing agent (SRA) of the tropane family related to the tryptamines. It is potent, selective, and shows full efficacy as an SRA in serotonin transporter (SERT)-transfected HEK293T cells. This includes selectivity for the SERT over the dopamine transporter (DAT) and norepinephrine transporter (NET). However, the drug also shows substantial interaction with the serotonin 5-HT3 receptor and the sigma σ1 and σ2 receptor (92.5–95.1% binding inhibition, relative to 94.9% at the SERT). The chemical synthesis of UCD0168 has been described. Analogues of UCD0168 have been described, for instance UCD0820, which is a poorly selective SRA with partial releasing efficacy. UCD0168 was first described in the scientific literature by David E. Olson and colleagues at the University of California, Davis (UCD) in 2025.

Worked examples

Example 1 — a first encounter with UCD0168

Start with the simplest possible case. Write down what UCD0168 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 UCD0168 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 UCD0168 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 UCD0168

In research: UCD0168 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 UCD0168 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: UCD0168 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drugs not assigned an ATC code, Indoles, Methyl compounds, so understanding it makes those chapters shorter.
In everyday life: Look for UCD0168 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.
