Summary
New pseudosaccharin amine derivatives were synthesized and screened for activity. Compounds 4k and 4m showed potential as reversible inhibitors of Human Leukocyte Elastase (HLE), with specific inhibitory constants.
Area of Science:
- Medicinal Chemistry
- Organic Synthesis
- Enzyme Inhibition
Background:
- Human Leukocyte Elastase (HLE) is implicated in various inflammatory diseases.
- Developing novel inhibitors for HLE is crucial for therapeutic interventions.
Purpose of the Study:
- To synthesize novel pseudosaccharin amine derivatives.
- To evaluate their potential as Human Leukocyte Elastase (HLE) inhibitors.
Main Methods:
- Synthesis of pseudosaccharin amines via pseudosaccharin chloride and amines.
- Synthesis of alkyl [(1,1-dioxo-benzo[d]isothiazol-3-yl)amino]alkanoates using amino acid esters and pseudosaccharin chloride.
- Screening of synthesized compounds for HLE inhibitory activity.
Main Results:
- Two synthetic routes for pseudosaccharin amines were established, with the direct reaction of pseudosaccharin chloride yielding higher results.
- Alkyl [(1,1-dioxo-benzo[d]isothiazol-3-yl)amino]alkanoates were successfully synthesized.
- Compounds 4k and 4m were identified as reversible HLE inhibitors with Ki values of 45 µM and 60 µM, respectively.
Conclusions:
- Pseudosaccharin amines can be effectively synthesized.
- Novel compounds were developed as potential therapeutic agents targeting HLE.
- Compounds 4k and 4m demonstrate promising reversible HLE inhibitory activity.
