Surface Plasmon Resonance Sensors Based on the Molecularly Imprinted Technique for Simvastatin Detection.[Pubmed:41552491]
ACS Omega. 2025 Dec 22;11(1):833-843.
In this study, surface plasmon resonance (SPR)-based sensors were developed to determine simvastatin (SIM) with phosphate buffer (pH 7.4) using the molecular imprinting technique (MIT). SIM imprinted (MIP) and nonimprinted (NIP) poly-(2-hydroxyethyl methacrylate-N-methacryloyl-L-Tryptophan methyl ester) polymeric films were synthesized onto the surface of the SPR chips to obtain kinetic parameters. The characterization of the MIP and NIP sensors was determined by contact angle and atomic force microscopy measurements. The range of linearity was measured as 0.001-1.0 mg/mL for SIM imprinted polymeric film-based SPR sensors. The selectivity of SPR sensors for competitive adsorption of atorvastatin and rosuvastatin was also investigated. After optimizing the experimental studies for SIM determination, SIM determination was also performed in artificial plasma solutions, and the recoveries were calculated to be approximately 99%. The findings indicate that SIM imprinted SPR sensors demonstrate exceptional sensitivity and selectivity along with a remarkably low detection limit for precise target identification.
In Vitro Study of Antiviral Properties of Compounds Based on 1,4-Dioxane Derivative of Closo-Decaborate Anion with Amino Acid Ester Residues Against Influenza Virus A/IIV-Orenburg/83/2012(H1N1)pdm09.[Pubmed:39769975]
Molecules. 2024 Dec 13;29(24):5886.
New derivatives of the closo-decaborate anion [B(10)H(9)-O(CH(2))(2)O(CH(2))(3)C(O)-L-OCH(3)](2-) (An) (1: L = Trp; 2: L = His; 3: L = Met; 4: L = Ala(2-oxopyrrolidin-3-yl) (Pld) were synthesized and isolated as tetraphenylphosphonium salts (Ph(4)P)(2)An. Anions 1(2-); 2(2-); 3(2-), and 4(2-) contain a pendant functional group from the L-Tryptophan methyl ester, L-histidine methyl ester, L-methionine methyl ester, or methyl 2-amino-3-(2-oxopyrrolidin-3-yl)propanoate (-Trp-OCH(3), -His-OCH(3), -Met-OCH(3), or -Pld-OCH(3)) residue, respectively, bonded with the boron cluster anion through the oxybis[(ethane-2,1-diyl)oxy] spacer. This pacer is formed as a result of the nucleophilic opening of the attached dioxane molecule in the [B(10)H(9)O(CH(2))(4)O](-) starting derivative. Sodium salts of the target compounds were isolated and used in biological experiments. It was established that among compounds Na(2)An (An = 1-4), not all are capable of inhibiting the cytopathic effect of the virus in vitro. Sodium salts Na(2)An have a low toxic effect on a monolayer of continuous canine embryonic kidney (MDCK) cell line. Compounds Na(2)1 and Na(2)2 had IC(50) of 5.0 and 20.0 mug/mL, respectively, while for compounds Na(2)3 and Na(2)4, IC(50) values could not be achieved at the concentrations studied. The studies performed for molecular docking of the anionic part of 1(2-) and 2(2-) with the transmembrane domain of viroporin M2 show some differences in the location of these two ligands inside the M2 canal pore.
