What if one simple graph could reveal the true power of a drug? From assessing drug potency to predicting effects, these curves aren't just for data—they’re your entry point to understanding drug behavior at a deeper level. real insight You'll leave with practical tools and a new appreciation for the humble curve that powers drug discovery.

Engineered G protein-coupled receptors (GPCRs) are commonly used in chemogenetics as designer receptors exclusively activated by designer drugs (DREADDs). Although several GPCRs have been studied in astrocytes using a chemogenetic approach, the functional

In drug discovery, equilibrium constants look tidy. But biology isn’t tidy. Kinetics in Drug Discovery: Your Edge If you’re still treating potency as a static number, you’re missing It’s a shift in how expert drug hunters see pharmacology. But discovery doesn’t.

Neuropeptides and their specific receptors (primarily G protein-coupled receptors, GPCRs) regulate multiple A total of 41 neuropeptide GPCR genes belonging to three classes were also identified. These GPCRs and their probable ligands were predicted. expression patterns of these 98 genes in various larval tissues were evaluated using quantitative real-time PCR to determine physiological functions and pharmacological characterization of neuropeptides and their GPCRs

Class B G protein-coupled receptors (GPCRs) are notoriously difficult to target by small molecules because Using the parathyroid hormone type 1 receptor (PTHR) as a prototypic class B GPCR target, and a combination precise druggable sites and identify allosteric modulators of PTHR signaling that could be extended to GPCRs to expedite discoveries of small molecules as novel therapeutic candidates.

According with the National Institute on Drug Abuse (NIDA) nearly 92, 000 Americans died from drug-involved Opioids are analgesic drugs consumed non-medically for euphoric feelings and medically for pain relief of the nervous system to painful stimuli; the 1970s marked the beginning of its study with the first discoveries central nervous system that were recognized by exogenous opioids such as morphine, leading later to the discovery Opioid receptors belong to class A of G protein-coupled receptors or GPCRs and signaled mainly through

In drug discovery, intuition creeps in. Eyes deceive. The first trap in drug discovery is relying on visual inspection. Scatter can masquerade as signal. Statistical Methods in Drug Discovery: Your Edge If you’re still making calls by sight, habit, or tradition It’s a shift in how you approach discovery. And once you make that shift, you’ll never go back. Here, you’ll find: Weekly lectures  that sharpen the tools you actually use in discovery A growing on-demand
