Summary
We developed a new strategy to improve drug molecules by dissecting their structure and optimizing components. This method led to a significantly enhanced ligand for the smoothened receptor (SMO).
Area of Science:
- Medicinal Chemistry
- Structural Biology
- Drug Discovery
Background:
- The smoothened receptor (SMO) is a key target in various therapeutic areas.
- Optimizing small molecule ligands requires understanding structure-activity relationships.
- Existing ligands may have suboptimal interactions with their targets.
Purpose of the Study:
- To introduce a novel "dissection-then-evolution" strategy for ligand optimization.
- To systematically analyze the contribution of ligand fragments to target binding.
- To develop an improved ligand for the smoothened receptor (SMO).
Main Methods:
- Utilized the co-crystal structure of the smoothened receptor (SMO) as a structural guide.
- Employed a "silencing" approach to assess the modular contribution of ligand interactions.
- Focused optimization efforts on specific ligand fragments, such as the benzoyl moiety.
Main Results:
- Successfully identified key interactions contributing to ligand efficacy.
- Demonstrated the effectiveness of the dissection-then-evolution strategy.
- Developed an improved ligand, designated as compound 21, with enhanced properties.
Conclusions:
- The "dissection-then-evolution" strategy is a powerful tool for rational ligand design.
- Systematic analysis of ligand-receptor interactions can guide optimization efforts.
- The optimized ligand 21 represents a promising advancement for SMO-targeted therapies.

02:55The Evidence for Evolution
48.3K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

00:49Ligand Binding and Linkage
5.6K
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

01:54Convergent Evolution
33.0K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

01:31Internal Receptors
74.7K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

24.4K
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

11.8K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
