Seventeen new highly fluorinated phosphoramidates containing alkylamino moieties of the type (RFO)2P(O)NHR (R = CH2CH2CH3, (CH2)3CH3, (CH2)4-CH3, CH(CH3)2, C6H11, CH2CH2-C6H5, CH2-C6H5 or C6H5; RF CH2CF3, CH2C2F5 CH2CH2C6F13) were synthesized. These compounds obtained through reaction primary amines with bis(polyfluoroalkyl)phosphites as phosphorylating agents, using molecular iodine a mild catalyst and in presence H2O2.This method was chosen out various literature common methods, which thoroughly investigated 31P NMR spectroscopy. In addition, variation rates among different phosphites studied compared previous research findings. The title fully characterized multinuclear (1H,13C,31P, 19F) NMR, IR, HRMS techniques.

ABSTRACT Entecavir and penciclovir are nucleoside‐analog antiviral drugs structurally related to guanine that act by inhibiting the active viral replication process. Through this study, quantitation of both was carried out using two fluorescent probes, referred as fluoroprobes. The first type prepared addition surfactants such Tween 80 sodium dodecyl sulfate (micelle‐enhanced fluoroprobes), while second includes formation a tertiary complex drug‐terbium‐DNA (Tb‐DNA fluoroprobes). preparation fluoroprobes optimized analytical quality design (AQbD) via I‐optimal design. A positive effect selected on DNA mismatching observed. procedures were validated according ICH guidelines with linearity range 2.0–40.0 μM 25.0–300.0 nM for micelle‐enhanced Tb‐DNA fluoroprobes, respectively. evaluated in compliance three‐color (GBW) assessments: greenness (using AGREE ComplexGAPI metrics), blueness BAGI tool), whiteness RGB algorithm). sustainability profiles established efficient‐valid‐green (EVG) framework. Both types successfully applied quantify entecavir content uniformity testing spiked human plasma simpler cheaper alternative hyphenated techniques.

A straightforward, reliable, and cost-effective spectrofluorimetric approach has been established for the analysis of baloxavir marboxil (BXM) in raw material, tablets, as well spiked human plasma. The relies on BXM's quenching impact acetoxymercuric fluorescein (AMF) fluorescence intensity. To improve reaction, factors such AMF's concentration, solution's pH, diluting solvents, reaction time were examined optimized. Linearity, range, accuracy, precision, LOD, LOQ all verified compliance with ICH criteria. concentration range was shown to be linear between 0.2 2 μg/mL. technique effectively utilized BXM both its tablet plasma, mean % recoveries 101 ± 0.36 98.77 0.65, respectively. Two assessment models (AGREE RGB-12) used compare proposed process's greenness sustainability four previously published chromatographic techniques. Higher green qualities declared by suggested than earlier ones.
