New sulfur and selenium compounds were synthesized and tested as inhibitors for Carbonic Anhydrases (enzymes). X-ray studies revealed the inhibition mechanism, offering insights into drug design.
Area of Science:
- Organic Chemistry
- Medicinal Chemistry
- Biochemistry
Background:
- Carbonic Anhydrases (CAs) are crucial enzymes involved in various physiological processes.
- Developing novel CA inhibitors is important for treating diseases like glaucoma and epilepsy.
- Sulfur and selenium containing organic molecules offer unique chemical properties for drug development.
Purpose of the Study:
- To synthesize novel chalcogen-containing amides and esters with a benzenesulfonamide group.
- To investigate the in vitro inhibitory activity of these compounds against Carbonic Anhydrases.
- To elucidate the mechanism of inhibition using X-ray crystallography.
Main Methods:
- Nucleophilic conjugate addition of thiols and selenols to electron-deficient alkenes.
- In vitro enzyme inhibition assays for Carbonic Anhydrases.
- X-ray diffraction studies to determine the binding mode and inhibition mechanism.
Main Results:
- Successful synthesis of novel chalcogen-containing benzenesulfonamide derivatives.
- Demonstrated in vitro inhibitory activity of the synthesized compounds against Carbonic Anhydrases.
- Elucidation of the binding interactions and inhibition mechanism through X-ray crystallography.
Conclusions:
- The synthesized chalcogen-containing amides and esters are potent inhibitors of Carbonic Anhydrases.
- The study provides valuable structural insights into the inhibition mechanism.
- These findings contribute to the design of new therapeutic agents targeting Carbonic Anhydrases.

Alkynes to Aldehydes and Ketones: Acid-Catalyzed Hydration
Analogous to alkenes, alkynes also undergo acid-catalyzed hydration. While the addition of water to an alkene gives an alcohol, hydration of alkynes produces different products such as aldehydes and ketones.

Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
