The goal of the current work was to create structural analogues of a beta lactam antibiotic that might be possibly effective against bacterial resistant strains. FTIR, 1H NMR, 13C NMR, and CHNS analyses were used to perform the spectroscopic study on the compounds M1–8. The effects of the aforementioned substances on gram-positive and gram-negative bacterial strains were investigated. Most of the eight compounds had antibacterial activity that was lower than or equivalent to that of the original medication, but two molecules, M2 and M3, surprisingly, had stronger antibacterial activity. The findings of synthesized analogues against alpha-glucosidase and DPPH inhibition were found to be modest, whereas M2, M3, and M7 strongly inhibited the urease. To comprehend the potential mode of action, a molecular docking research was conducted against urease and -amylase. The research may help in the quest for novel chemical compounds that would be effective against bacteria that are resistant to antibiotics.
Prodrugs of dexibuprofen having ester moieties instead of free carboxylic acid which involves in gastrointestinal side effects have been synthesized. Dexibuprofen acid was condensed with different alcohols/phenols to afford the ester prodrugs. All of the synthesized prodrugs were characterized by their physical attributes, elemental analysis, FT-IR, 1 H-NMR, and 13 C-NMR spectroscopy. The in vitro anti-inflammatory studies was done by chemiluminescence technique reflect prodrugs have been more potent, owing to the different chemical structures. Lipoxygenase enzyme inhibition assay was also assess and found compound DR7 with IC 50 = 19.8 μM), DR9 (IC 50 = 24.8 μM) and DR3 (IC 50 = 47.2 μM) as compared with Dexibuprofen (IC 50 = 156.6 μM). It was also evaluated for docking studies revealed that DR7 has found to be more potent anti-inflammatory against 5-LOX (3 V99) as well as analgesic against COX-II (5KIR) enzyme. Anti-oxidant activities were also performed, DR3 (86.9 %), DR5 (83.5 %), DR7 (93.9 %) and DR9 (87.4 %) were found to be more anti-oxidant as compared to (2S)-2-[4-(2-methylpropyl)phenyl]propanoic acid (52.7 %).
The current study was designed to synthesize, characterize, and screen the molecular and biological activities of different metformin derivatives that possess potent antidiabetic potential with minimal side-effects. Metformin-based derivatives containing the metal complexes Cu II (MCu1–MCu9) and Zn II (MZn1–MZn9) were generated using aromatic aldehydes and ketones in a template process. The novel metal complexes were characterized through elemental analysis, physical state, melting point, physical appearance, Fourier-transform infrared (FTIR) spectroscopy, UV/visible (UV/Vis) spectroscopy, 1H nuclear magnetic resonance (NMR) spectroscopy, and 13C-NMR spectroscopy. Screening for inhibitory activity against the enzymes α-amylase and α-glucosidase, and molecular simulations performed in Schrödinger were used to assess the synthesized derivatives’ biological potential. Met1, Met2, Met3, and Met8 all displayed activities that were on par with the reference in an enzymatic inhibition assay (amylase and glucosidase). The enzyme inhibition assay was corroborated by molecular simulation studies, which also revealed a competitive docking score compared to the gold standard. The Swiss ADME online web server was utilized to compute ADME properties of metformin analogues. Lipinski’s rule of five held true across all derivatives, making it possible to determine the percentage of absorption. Metformin derivatives showed significant antidiabetic activities against both targeted enzymes, and the results of this work suggest that these compounds could serve as lead molecules for future study and development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
