The synthesis and antimicrobial activity of $gamma$- butyrolactone derivatives

This paper examines the synthesis of $gamma$-butyrolactone compounds 2, 3, 4, 5, and 9, and their potential antimicrobial nature and ability. The structures of all the compounds mentioned above were determined and confirmed with elemental analyses, and IR, $^1H-NMR$, and $^{13}C-NMR $ spectroscopy. The in vitro antimicrobial activity of compounds 2, 3, 4, 5, and 9 was examined and evaluated against the following pathogens: Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae, Aspergillus niger, and Candida albicans. Compound 5 (20 mg/mL) demonstrated high antimicrobial activity against S. epidermidis, which was closely comparable to the antimicrobial activity of streptomycin.

21. DEPT $^{13}C NMR$: Quaternary carbons are not observed, while others are positive, negative, or null depending on the "angle" (45°, 90°, 135°) used in the experiment. This technique effectively identifies the most basic structural units: C, CH, CH2, and CH3.
