Synthesis and biological evaluation of new aza-acyclic nucleosides and their hydrogen complexes from indole
(SpringerLink, 2022) Alhilal, Suzan; Alhilal, Mohammad; Gomha, Sobhi M.; Ouf, Salama A.
Three novel aza-acyclic nucleosides and two hydrogen complexes were isolated by flash chromatography after being produced in a reaction between indole and dibenzosulfonyl diethylamine (which had previously been prepared) in the presence of sodium and absolute ethanol as a basic catalyst. Structures of new compounds and complexes were determined by 1D-NMR: 1H NMR, 13C NMR, DEPT-135, 2D-NMR: COSY, HMQC, HSQC, HMBC, IR, and MS spectroscopy. The synthesized compounds were evaluated against a wide range of microorganisms, including Gram-positive and Gram-negative bacteria as well as fungal strains. These compounds showed good biological activity.
Synthesis of Novel Acyclic Nucleoside Analogue Starting From 6-Aminouracil as Potent Antimicrobial Agent
(Polycyclic Aromatic Compounds, 2021) Alhilal, Mohammad; Sulaiman, Yaser A. M.; Alhilal, Suzan; Gomha, Sobhi M.; Ouf, Salama A.
6-Aminouracil and 2-bromoethyl amine were prepared, as starting materials to be introduced as an alkylating reagent with sodium carbonate as a catalyst. Acyclic nucleoside was prepared for the first time, the expected structure of the final new compound 3 was determined based on IR, NMR, and mass spectroscopy, with safe and mild reaction conditions. The synthesized acyclic nucleoside has a potent and efficient antimicrobial activity compared to reference drugs particularly as an antibacterial agent, and can be used as an alternative to the commonly used antibiotics after performing the necessary biological research for its validation.
