Synthesis and Biological Activity of Barbituric acid- linked Isatin Derivatives.

The study focuses on the synthesis of isatin- barbituric acid compounds through a two-step process. In the first step, using mannich reaction, new derivatives of Isatin are synthesized by reacting Isatin with either barbituric acid, along with formaldehyde. This reaction results in the formation of Isatin-barbituric acid derivative. In the second step, these Isatin derivatives are further reacted with various aniline derivatives to generate new compounds containing Isatin. Spectroscopic methods including FTIR, ¹H NMR, and 13C NMR are used to characterize the produced molecules. The study investigates the biological effects of several of the synthetic chemicals on certain bacterial strains, including Klebsiella pneumoniae and Staphylococcus aureus. The potential antibacterial activities of these substances are evaluated. [ABSTRACT FROM AUTHOR]
