Hetacillin (R)- and (S)-sulfoxides. Synthesis and structure-activity relationships
Journal of Medicinal Chemistry
|February 1, 1978
Summary
Hetacillin oxidation yielded (R)- and (S)-sulfoxides. The (R)-sulfoxide demonstrated significantly greater biological activity compared to the (S)-sulfoxide, indicating stereospecificity in hetacillin
Area of Science:
- Medicinal Chemistry
- Organic Chemistry
- Pharmacology
Background:
- Hetacillin is a penicillin derivative.
- Understanding the chemical transformations and biological activity of hetacillin is crucial for drug development.
Purpose of the Study:
- To investigate the oxidation products of hetacillin.
- To evaluate the biological activity of these oxidation products.
Main Methods:
- Oxidation of hetacillin using m-chloroperbenzoic acid.
- Ozonization of hetacillin.
- Assessment of biological spectrum for synthesized compounds.
Main Results:
- m-Chloroperbenzoic acid oxidation produced (R)- and (S)-hetacillin sulfoxides.
- Ozonization resulted in both sulfide oxidation and imidazolidine ring oxidation to a 2H-imidazoline.
- (R)-hetacillin sulfoxide exhibited notably higher biological activity than the (S)-enantiomer.
Conclusions:
- Stereochemistry plays a significant role in the biological activity of hetacillin derivatives.
- Different oxidation methods yield distinct products with varying pharmacological profiles.
