Disposal and burning of biomass-derived from relevant agricultural waste indiscriminately pollutes the environment and increases greenhouse gas emissions. Researchers have been exploring the “waste to wealth creation” policy due to the renewable nature and availability of agricultural wastes. In this study, agricultural wastes (groundnut shell (K), walnut shell (G), and wood carpentry waste (N)) were investigated for potential use in silica production. Initially, to obtain the ash, the samples were burned. The chemical method was then used to extract fine powder silica in the nanoscopic range using a simple bottom-up approach. To confirm the results, the samples were examined by XRD, SEM with EDX, and FT-IR, which were used to analyze the extracted silica nanoparticles. The isolated silica nanoparticles have a unit size of 9 – 30 nm, according to microstructural examination. EDX verified the presence of SiO2 in the sample. FT-IR analysis also reveals the presence of siloxane group.

Aim of study was to develop bilayer drug delivery for treatment of attention deficit hyperactivity disorder (ADHD) by delivering loading and maintenance dose for fast achievement of peak plasma concentration and maintaining the same respectively. The prepared drug loaded bilayer tablets were evaluated for pre and post compression parameters. The tablets were prepared by direct compression and wet granulation method. The loading dose was delivered in the form of immediate release layer prepared by different super-disintegrations and maintenance dose was delivered through sustained release layer prepared by using polymers like Ethyl cellulose and Carbopol. Both the immediate release layer and sustained release layers were separately optimized and then combined to optimize the bilayer tablets. No interactions were found between drug and excipients. Formulation containing Cross Carmellose shows immediate drug release. Formulation Containing Carbopol shows sustained release action and bilayer formulations F5 shows releases up to 12 hours. Bilayer tablets with release characteristics offer critical advantages such as, site specificity with improved absorption and efficacy.

EU Directive for the Protection of Laboratory Animals mandates and encourages the use of alternative methods that could substitute, cut down on, and generally improve animal testing. Quantitative structure-activity relationship models (QSAR) as well as in vitro toxicity testing are among the most notable of such. QSARs are defined as computerized mathematical models that can utilize a compound’s (aromatic amine) biological activity—aquatic toxicity—to calculate or provide the experimental descriptors of the chemical structure of this compound. Multiple Linear Regression (MLR) and Artificial Neural Networks (ANN) are the approaches we use for the aim of predicting aquatic toxicity. The best models for two descriptors are the electrotopological descriptors derived from E-calc, and the partition coefficient derived by the Hyperchem software, applying a genetic algorithm—variable subset selection procedure. The important values of the statistical parameters obtained by the two approaches were as follows: By MLR: R2= 92.18, Q2 = 90.51, Q2ext= 95.26, F=188.5466, S = 0.1995. By ANN were: Q2 = 94.79, RMSE= 0.16, Q2ext= 91.71, RMSEext=0.18.

Simple sensitive and accurate ion pair complex formation with reactive dyes, extractive spectrophotometric methods have developed for the estimation of favipiravir in pharmaceutical dosage form. The methods are based on the formation of ion paired coloured complexes by the drug with reactive dyes like Congo red, eriochrome black T and methyl orange in acidic medium. The ion associated complexes were formed and quantitatively extracted under the experimental condition in chloroform. The absorbance values were measured at 490 nm, 500 nm, and 430 nm respectively. The proposed methods were validated statistically. Recoveries of methods were carried out by standard addition method. The linearity was found to be 5.0-30.0 μg/ml, 5 -12 μg/ml, and 2-20 μg/ml for methods respectively. The low values of standard deviation and percentage RSD indicate high precision of methods. Hence these methods are useful for routine estimation of favipiravir in pharmaceutical dosages.

Plant-based products are a one-of-a-kind source of favoured molecules with a wide scaffold variety and broad multi-target potential for the treatment of complicated disorders. Among multi-target NPs, alkaloids have showed anti-inflammatory, anticancer, cardioprotective, and neuroprotective effects, supporting their promise in the treatment of chronic multifactorial disorders. Several recent investigations have revealed that isoquinoline alkaloids (IAs) have multimodal potential, sparking growing interest in the polypharmacological research of these small molecules, particularly in the field of neurological illnesses and cancer. IAs are a broad and diversified category of nitrogenous compounds that are extensively dispersed in living organisms, mostly in plants family. Isoquinolines are known as highly conserved metabolites in early vascular plants at the chemotaxonomic level; moreover, biochemical and molecular phylogenetic investigations have revealed that these alkaloids play an evolutionarily monophyletic role in basal angiosperms.As a result, medicinal chemistry has been experimenting with various ways in order to overcome the constraints of existing paradigms and increase the effectiveness of novel therapeutic molecules. In this context, the search or design of multi-target medications has shown an accelerated breakthrough; in fact, this strategy has sparked the interest of both the scientific community and the pharmaceutical business, allowing several multimodal agents already on the market to be positioned.

Thiazolidin-4-one derivatives have been hailed as “wonder nucleus” due to their profound biological activities. A number of derivatives with variable functional groups attached to the five-membered heterocyclic ring which have been synthesized and further subjected to molecular docking studies, against C-KIT Tyrosine kinase target protein (1T46). The interactions, binding and affinity variations due to differences in functional groups have been studied using ChemDraw Ultra 7.0, RCSB – Protein Data Bank, BIOVIA Discovery Studio Visualizer 2021, MGL AutoDock Tools, AutoDock Vina and Vina Split software. The docking studies showed good interaction of the synthesized molecules with the 1T46 target protein. The ADME studies of these molecules have also been studied to identify which of the synthesized molecules have the potential to cross the Human Intestinal lining (HIA), as well as the BBB barrier. Out of the 18 molecules studied, 12 of them showed good potential to be absorbed by the intestine out of which only one molecule was able to show potential to cross the BBB barrier. There were 4 molecules that could not cross both the barrier. These studies could reveal which functionalities present attached to the thiazolidin-4-one could assist in human intestinal absorption and the crossing of the BBB barrier.

The objective of this work is to highlight the purification performance of the Mentha longifolia plant for wastewater under a horizontal flow regime and a hot and dry (arid) climate. In this research, we made a comparison between a planted bed of Mentha longifolia and a non-planted bed (control) as well as the study of the performance of the Mentha longifolia to purify the wastewater. The study is carried out according to an experimental pilot in the urban wastewater treatment zone within the National Sanitation Office (NSO) in Tamanghasset. The experimental pilot consists of pots of capacity 130 liters filled from bottom to top on a thickness of 45 cm of gravel (15 / 25mm) of 10 cm of sand. The pot is planted with young stems of Mentha longifolia (36 stems / m2) and the other non-planted pot is taken as a control. The pots are fed by urban wastewater (18 liters / day), once a week. The water obtained after 5 days is collected in a container located under the pot. The performance information shown is for the periods from the month of January - April 2021.After four months of follow –up, we obtained the pollutant removal results with the following percentages: COD (77.74%), BOD5 (72.47%), MES (87.78%), NO3-(63.40%), NO2- (62.03%), PO43- (62.77%), E. coli (99.43%). The existence of the plant Mentha longifolia in planted beds maintains a sufficient porosity that prevents clogging. The significant reduction of pollutants and pathogenic microorganisms allows us to consider the reuse of treated water in agriculture and industry.

The significant reduction of pollutants and pathogenic microorganisms allows us to consider the reuse of treated water in agriculture and industry.","PeriodicalId":8550,"journal":{"name":"Asian Journal of Research in Chemistry","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89015211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new, simple, precise, rapid, selective and stability reversed-phase high performance liquid chromatographic (RP-HPLC) method has been developed and validated for the simultaneous quantification of Perphenazine and Amitriptyline in pure form and its pharmaceutical dosage form. The method is based on Phenomenex Gemini C18 (4.6×250mm) 5µ column. The separation is achieved using isocratic elution by Methanol: TEA Buffer in the ratio of 65:35% v/v, pumped at flow rate 1.0mL/min and UV detection at 230nm. The column is maintained at 40°C throughout the analysis. The total run time is about 6min. The method is validated for specificity, accuracy, precision and linearity, robustness and ruggedness, system suitability, limit of detection and limit of quantitation as per International conference of harmonization (ICH) Guidelines. The method is accurate and linear for quantification of Perphenazine, Amitriptyline between 10 - 50µg/mL and 20 - 100µg/mL respectively. Further, satisfactory results are also established in terms of mean percent- age recovery (100.37% for Perphenazine and 100.34% for Amitriptyline, intra-day and inter-day precision (<2%) and robustness. The advantages of this method are good resolution with sharper peaks and sufficient precision. The results indicate that the method is suitable for the routine quality control testing of marketed tablet formulations.
