Facile Integration of Hanztsch's Switch-Off/On Modeled Fluorogenic Probe for Feasible Tagging and Tracking of the Midodrine Drug in Different Matrices; First Evaluation of the Method's Greenness, Whiteness, Blueness, Quantum Yield, and Tablets' Content Homogeneity

The proposed investigation follows a certain methodology to guarantee that the procedure employed is sustainable and green. It is noteworthy to mention that various tools have been implemented as potential indicators of environmental sustainability (greenness and whiteness). From a novelty viewpoint, a new tool, BAGI, for the method's blueness evaluation was applied to the planned method and showed a high applicability score. Fortunately, the WAC concept, which combines ecological and functional variables using the Green/Red/Blue design (RBG 12 tool), identifies the established analytical approach as white. In the planned study, a new, green, simple, nano-trace-sensitive, original fluorimetric methodology was established to analyze and assess midodrine hydrochloride content in different matrices. Midodrine's primary amine moiety reacts with Diacetylmethane/Oxymethylene reagent in an acetate buffer, which leads to generating a fluorescent dihydrolutidine derivative (Hantzsch-named reaction). Consequently, the signal strength of this compound was quantified at 487 nm, with an excitation wavelength of 426 nm. This analysis indicated that the technique exhibited linearity within the range of 0.05 to 1.1 µg mL-1 concentrations, accompanied by remarkably good sensitivity values (LOD and LOQ). The methodology employed in this examination was subjected to validation following the rules recognized by ICH. From the perspective of pharmacy and chemistry, the method presented in this study was successfully employed to analyze commercially available tablets, oral drops, and human fluids. The outcomes obtained demonstrated satisfactory recovery rates without any interference from excipients. Following the USP recommendations, the intended technique was finally implemented to explore the content homogeneity evaluation.

Integration of a facile sustainable resonance Rayleigh scattering switchable-based system for feasible determination of centrophenoxine, a nootropic and antioxidant agent; application to crude materials and dosage forms

The proposed research adheres to a certain methodology to ensure that the technique used for analyzing the centrophenoxine drug is sustainable and green. It is important to highlight that several tools that have been recently developed were utilized as potential indicators of environmental sustainability and applicability. The present research presents a novel and entirely innovative method utilizing ultrasensitive spectrofluorimetry for the detection of centrophenoxine (CPX) drug. The employed methodology in this study involved the utilization of one-step, one-pot, and direct spectrofluorimetric technique, which was found to be both efficient and environmentally sustainable in the validation and assessment of the drug. Simply, when CPX and erythrosine B reagent were combined in an acidic environment, the highly resonance Rayleigh scattering product was immediately produced. The sensitivity limits were observed to be within the range of 15-47 ng mL-1, whereas the linearity was assessed to be in the range of 50-2000 ng mL-1. The optimal settings for all modifiable parameters of the system were ascertained through an analysis of centrophenoxine-erythrosine B complexes. Moreover, the system demonstrated compliance with International Council for Harmonization (ICH) specifications without encountering any issues. The suggested process was then rated on different recent environmental safety measuring metrics to see how good it was for the environment. Fortunately, the WAC standards that combine ecological and functional elements utilizing the Green/Red/Blue (RGB 12) design also acclaimed the current analytical technique as a white one. Additionally, a new applicability evaluation tool (BAGI) was employed to estimate the practicability of the planned method in the analytical chemistry field.

The suggested study adheres to a particular protocol to ensure that the process is environmentally friendly and sustainable. It is worth mentioning that several tools have been adopted as prospective measures of the method greenness. Fortunately, the established analytical method is identified as white by the white analytical chemistry (WAC) concept, which uses the red/ green/blue color scheme (RGB 12 tool) to combine ecological and functional factors for the first time in studying of the cited drug. Amlodipine (AMD), a cardiovascular treating agent, belongs to the dihydropyridine class of oral calcium channel-blocking agents. This article presents a novel, simple, green, one-pot-processed, fast, and ultrasensitive fluorimetric approach for monitoring and assessment of AMD using molecular-size-dependent fluorescence augmentation of the light scattering-driven signal of eosin, a biological stain at a wavelength of 415 nm. This enhancement was directly proportional to the size of the produced complex. The linearity range was from 30 to 900 ng mL-1 , with corresponding sensitivity limits (detection and quantitation levels) of 9.2 and 28 ng mL-1 , respectively. The planned approach was also successfully used to track AMD content in bulk, dosage forms, and bio-fluids (human plasma and urine). The developed method's eco-friendliness was established by different eco-rating metric tools.

The first facile optical density-dependent approach for the analysis of doxorubicin, an oncogenic agent accompanied with the co-prescribed drug; paclitaxel

Doxorubicin (DRB) is an anthracycline oncogenic drug extracted from cultures of Streptomyces peucetius var. caesius. It is frequently recommended as an anti-neoplastic agent for the treatment of diverse malignancies. It exerts its antineoplastic effect either via inhibiting the enzyme topoisomerase II and/or via intercalation to DNA or reactive oxygen species generation. In the present article, the direct, simple, one-pot, somewhat eco-safe, and non-extractive spectrophotometric system was executed to track doxorubicin, a chemotherapeutic remedy, in the presence of paclitaxel, a naturally occurring Taxan antineoplastic radical, through the greenness rated method. DRB's optical density was studied in various mediums and solvents to develop the current approach. An acidic ethanolic solution was found to increase the optical density of the sample significantly. At 480 nm., the most remarkable optical density was obtained. Various experimental factors, including intrinsic media, solvent, pH, and stability time, were investigated and controlled. The current approach achieved linearity within the 0.6-40.0 µg mL-1 range, accompanied by a limit of both detection and quantification (LOD and LOQ) of 0.18 and 0.55 µg mL-1, correspondingly. The approach was validated under the ICH guidelines (Quality Guidelines). The system's greenness and enhancement degree were estimated.

Facile decoration of one-pot fluorescence probe-patterned reaction for sensing and ultrasensitive determination of tradjenta, a new type 2 diabetes oral therapy

Type 2 diabetes can be cured by using tradjenta (also known as Linagliptin), a new therapeutic drug that is an inhibitor of the dipeptidyl peptidase-4 enzyme. Tradjenta is administered orally alone or in combination with metiguanide or empagliflozin. An easy and specific fluorimetric analysis of Tradjenta was developed and demonstrated in the present investigation. The Hantzsch reaction method, which generates a fluorescent dihydropyridine derivative, is the basis of this assay. In a Toerell-Stenhagen buffered solution, the unsubstituted amine group of Tradjenta interacted with 2,4-Pentadione/Oxomethane. Spectrofluorimetry was utilized for this investigation at an excitation/emission wavelength of 421/480 nm. When comparing the Tradjenta concentration to the tracked fluorimetric signal, the method revealed linearity over the concentration range of 0.05 to 1.2 µg/mL. By strictly altering system parameters and analyzing the validation factors following International Council for Harmonisation (ICH) requirements, the outcomes were achieved. Finally, the proposed approach was successfully applied to assay the drug not only in its raw form and prescribed formulations but also to evaluate the tablet's uniformity of content.

Facile utility of felumin, a biological dye for the first fluorimetric determination of l-tetramisole drug through an "on-off fluorescence" strategy

l-Tetramisole is an anti-nematode and immunomodulating agent employed medically to treat diseases caused by worms. It is also used as an immune system-modifying agent in rheumatoid arthritis and as assistant therapy in treating cancers in the colorectal, head, and neck regions. Felumin is a safe food dye used in feed additives, flavors, biostaining, and recently, in analytical tracking. This is the first innovative spectrofluorimetric approach to l-Tetramisole drug analysis. It is both efficient and environmentally benign and was evaluated and validated in this investigation using a green, one-pot, and direct spectrofluorimetric technique. Instant complexes were created by combining l-Tetramisole and Felumin in an acidic solution. The fluorometric investigation was performed based on the off-effect strategy of l-Tetramisole on the emission amplitude of a biological dye (Felumin) at 557.5 nm. The linear range was from 0.1 to 1.7 μg mL^-1, with sensitivity limits of 0.020 and 0.061 μg mL^-1, respectively. Analytical modulation of l-Tetramisole-Felumin complexes was done for all system parameters. The system was found to meet ICH criteria. Moreover, this technique successfully recovered the substance in the prescribed medicinal dosage forms. The created fluorimetric technique was also successfully employed to track the drug of interest in human biofluids, which was a major accomplishment. The kinetics of the reaction system was also studied further. Finally, the proposed method's environmental friendliness was evaluated on the eco-scale.
