Summary
Aromatic clusters in proteins, involving multiple aromatic residues, are crucial for protein function and ligand binding. Understanding these interactions aids in designing more effective ligands.
Area of Science:
- Biochemistry
- Structural Biology
- Computational Chemistry
Background:
- Intermolecular interactions, especially those involving aromatic rings, are vital for complex stability.
- Aromatic-aromatic interactions are classified by orientation (e.g., stacking, T-shaped) and influence stabilization.
- Protein 3D structures are essential for studying these interactions in protein-ligand complexes.
Purpose of the Study:
- To investigate the role of aromatic clusters in protein-ligand complexes.
- To explore the significance of aromatic clusters in ligand binding and design.
Main Methods:
- Computational chemistry approaches.
- Knowledge-based analysis of protein structures.
- Utilizing databases like the Protein Data Bank (PDB).
Main Results:
- Aromatic clusters, defined as three or more proximate aromatic residues, are prevalent in protein structures.
- These clusters are found in various protein-ligand complexes.
- Both individual proteins and aromatic clusters are present in protein-ligand complexes.
Conclusions:
- Aromatic clusters play a significant role in protein function, stability, and ligand recognition.
- The presence of aromatic clusters in protein-ligand complexes suggests their importance in ligand binding.
- Identifying and understanding aromatic clusters can facilitate efficient ligand design.

01:13Five-Membered Heterocyclic Aromatic Compounds: Overview
6.0K
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom,...

01:14NMR Spectroscopy of Aromatic Compounds
6.7K
Aromatic compounds can be identified or analyzed using proton NMR and carbon‐13 NMR. Typically, aromatic hydrogens or hydrogens directly bonded to the aromatic rings are strongly deshielded by the aromatic ring current. Therefore, they absorb in the range of 6.5–8.0 ppm in proton NMR spectra. For instance, aromatic hydrogens directly bonded to the benzene ring absorb at 7.3 ppm. However, aromatic hydrogens of larger rings absorb farther upfield or downfield than the ideal range.

4.3K
Neutral hydrocarbons like cyclopentadiene with an odd number of carbon atoms and one intervening CH2 group in the ring are not aromatic. Cyclopentadiene with 4 π electrons does not satisfy the 4n + 2 π electron rule. Additionally, the intervening CH2 group is sp3 hybridized and lacks a vacant p orbital, thereby interrupting the overlap of p orbitals in a continuous manner and preventing the delocalization of π electrons throughout the ring.

Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

01:23Mass Spectrometry: Aromatic Compound Fragmentation
2.7K
Upon ionization, aromatic compounds generate a molecular ion that is observed as a prominent peak in their mass spectra. For example, the molecular ion peak for benzene appears at a mass-to-charge ratio of 78, while toluene is observed at a mass-to-charge ratio of 92. The molecular ion benzene is highly stable and does not readily undergo further fragmentation due to the significant amount of energy required to disrupt the aromatic stability of the benzene ring. In contrast, the molecular ion...

In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.
