Reaction Mechanisms

28.5K
Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs.
For instance, the decomposition of ozone appears to follow a mechanism with two steps:

Coupled Reactions

Cellular processes such as building and breaking down complex molecules occur through stepwise chemical reactions. Some of these chemical reactions are spontaneous and release energy, whereas others require energy to proceed. Cells often couple the energy-releasing reaction with the energy-requiring one to carry out important cell functions. 
Energy in adenosine triphosphate or ATP molecules is easily accessible to do work. ATP powers the majority of energy-requiring cellular reactions....

Synthesis and Decomposition Reactions02:17

Synthesis and Decomposition Reactions

37.3K
Synthesis and decomposition are two types of redox reactions. Synthesis means to make something, whereas decomposition means to break something. The reactions are accompanied by chemical and energy changes.

Radical Reactivity: Intramolecular vs Intermolecular01:33

Radical Reactivity: Intramolecular vs Intermolecular

2.0K
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...

Enzyme Inhibition01:30

Enzyme Inhibition

88.7K
Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.

Limitations of Friedel–Crafts Reactions01:26

Limitations of Friedel–Crafts Reactions

6.3K
Several restrictions limit the use of Friedel–Crafts reactions. First, the halogen in the alkyl halide must be attached to an sp3-hybridized carbon for the Friedel–Crafts reactions to occur. Vinyl or aryl halides do not react since the carbocations formed are unstable under the reaction conditions. Second, Friedel–Crafts alkylation is susceptible to carbocation rearrangement, and the major products obtained have a rearranged carbon skeleton. In contrast, the acylium ion is...

Area of Science:

  • Medicinal Chemistry
  • Organic Synthesis

Background:

  • Covalent inhibitors are increasingly important in clinical settings, yet compound libraries are limited.
  • Multicomponent reaction (MCR) chemistry offers a powerful approach to rapidly access diverse chemical spaces.

Purpose of the Study:

  • To demonstrate the utility of MCRs for generating diverse libraries of covalent inhibitors.
  • To showcase the incorporation of various electrophilic warheads onto multiple scaffolds using MCRs.

Main Methods:

  • Utilized MCRs to synthesize libraries of electrophiles, including acrylamide, acrylic acid ester, sulfurylfluoride, chloroacetic acid amide, nitrile, and α,β-unsaturated sulfonamide warheads.
  • Incorporated these warheads onto 10 different scaffolds.
  • Performed synthesis on both preparative and nanoscale, high-throughput modes.

Main Results:

  • Successfully generated diverse libraries of potential covalent binders.
  • Demonstrated the compatibility of MCRs with various functional groups and scaffolds.
  • Achieved resource- and time-efficient synthesis.

Conclusions:

  • MCRs are highly suitable for the efficient and versatile synthesis of covalent inhibitor libraries.
  • The developed MCR strategy is simple, mild, and step-economical, facilitating future library synthesis.
