LK00764

LK00764 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 LK00764 rather than just read about it. In short: LK00764 is a trace amine-associated receptor 1 (TAAR1) agonist that is being investigated for the treatment of schizophrenia and other psychiatric disorders. The drug is a highly potent full agonist of the human TAAR1 with an EC50Tooltip half-maximal effective concentration of 4.0 nM and an EmaxTooltip half-maximal effective concentration of 101%.

Key takeaways

LK00764 belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect LK00764 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of LK00764 from memory before moving on to harder problems.

Reference excerpt

LK00764 is a trace amine-associated receptor 1 (TAAR1) agonist that is being investigated for the treatment of schizophrenia and other psychiatric disorders. The drug is a highly potent full agonist of the human TAAR1 with an EC50Tooltip half-maximal effective concentration of 4.0 nM and an EmaxTooltip half-maximal effective concentration of 101%. It is 30-fold more potent as a TAAR1 agonist than ulotaront (SEP-363856) in vitro. The drug has been found to reverse the hyperlocomotion in dopamine transporter (DAT) knockout mice and the hyperactivity induced by the NMDA receptor antagonist dizocilpine (MK-801) in rats, which are considered to be antipsychotic-like effects. It also attenuates stress-induced hyperthermia in rats, which is thought to be an anxiolytic-like effect. Hence, LK00764 appears to not only be an agonist of the human TAAR1, but also of the mouse and rat TAAR1, although this does not seem to have been assessed in vitro. LK00764 was first described in the scientific literature by 2018. It is being developed by Accellena. As of February 2025, the drug is in the preclinical research stage of development. LK00764 is structurally distinct from other known TAAR1 agonists but contains β-phenethylamine-like structural features.

Worked examples

Example 1 — a first encounter with LK00764

Start with the simplest possible case. Write down what LK00764 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 LK00764 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 LK00764 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 LK00764

In research: LK00764 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 LK00764 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: LK00764 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 4-Chlorophenyl compounds, Amines, Biphenyls, so understanding it makes those chapters shorter.
In everyday life: Look for LK00764 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.
