Reactivity of Enols01:18

Reactivity of Enols

4.2K
Enols are a class of compounds where a hydroxyl group is attached to a carbon–carbon double bond, which implies that it is a vinyl alcohol. A carbonyl compound with an α hydrogen undergoes keto–enol tautomerism and remains in equilibrium with its tautomer, the enol form. Usually, the keto tautomer is present in a higher concentration than the enol tautomer due to the higher bond energy of C=O compared to C=C. Moreover, the direction of the keto–enol equilibrium is...

Reactivity of Enolate Ions01:23

Reactivity of Enolate Ions

3.4K
Enolate ions are formed by the acid–base reaction of a carbonyl compound with a base. This leads to deprotonation of the α hydrogen atom, leading to a resonance-stabilized enolate ion where one of the contributing structures is an oxyanion, which imparts additional stability. Therefore, the proton on the α carbon is more acidic in nature than that of other sp3-hybridized C–H bonds but less acidic than those in O–H bonds where the negative charge in the conjugate...

Radical Reactivity: Overview01:11

Radical Reactivity: Overview

2.8K
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired...

Radical Reactivity: Nucleophilic Radicals01:16

Radical Reactivity: Nucleophilic Radicals

2.7K
Radicals adjacent to electron-donating groups are called nucleophilic radicals. These radicals readily react with electrophilic alkenes. The SOMO–LUMO interactions are the driving force for the reaction, where the high-energy SOMO of the electron-rich, nucleophilic radicals interacts with the low-energy LUMO of the electron-deficient, electrophilic alkenes. Such SOMO–LUMO interactions are the basis of reactive radical traps, affecting the selectivity in radical reactions. For...

Radical Reactivity: Intramolecular vs Intermolecular01:33

Radical Reactivity: Intramolecular vs Intermolecular

2.2K
Radical reactions can occur either intermolecularly or intramolecularly. In an intermolecular radical reaction, a nucleophilic radical adds to an electrophilic alkene or vice versa. In such reactions, the radical and generally the alkene, which is also called the radical trap, are two different molecules. Additionally, for such intermolecular reactions to occur, the radical trap must be active, present in an excess concentration, and the radical starting material must have a weak...

Summary
This summary is machine-generated.

Reactive arthritis, a type of spondylarthritis, often follows infections like diarrhea or urethritis. Treatment ranges from NSAIDs and physiotherapy to antibiotics for Chlamydia, with DMARDs or TNF-inhibitors for chronic cases.

Area of Science:

  • Rheumatology
  • Immunology
  • Infectious Diseases

Background:

  • Reactive arthritis is typically classified as a spondylarthritis.
  • It commonly presents as acute, asymmetrical oligoarthritis.
  • Symptoms often arise after infectious episodes, particularly diarrhea or urethritis.

Purpose of the Study:

  • To summarize the understanding of reactive arthritis, including its causes, presentation, and management.
  • To highlight the role of specific pathogens and treatment modalities.

Main Methods:

  • Review of current medical literature and clinical guidelines.
  • Analysis of common pathogens and their association with reactive arthritis.
  • Evaluation of therapeutic strategies for different disease presentations.

Main Results:

  • Frequent causative pathogens include Salmonella, Shigella, Campylobacter, and Chlamydia trachomatis.
  • First-line treatment involves non-steroidal anti-inflammatory drugs (NSAIDs) and physiotherapy.
  • Antibiotics are crucial for Chlamydia-induced cases; DMARDs and TNF-inhibitors are options for chronic or refractory disease.

Conclusions:

  • Reactive arthritis requires prompt diagnosis and tailored treatment based on etiology and chronicity.
  • Effective management strategies can mitigate disease progression and improve patient outcomes.
  • Understanding causative pathogens is key to targeted antimicrobial therapy.
