Enzymatic browning is a process that occurs in fruits and vegetables by the enzyme polyphenol oxidase, which results in brown pigments reduce shelf life which indirectly causes huge domestic loss to the farmers during the post-harvesting process. In this context, the present study was carried out to preserve and increase the shelf life of Brinjal vegetables from enzymatic browning using ascorbic acid. The seeds of Brinjal hybrid and wild were treated with (0.5-2%) concentrations of Ascorbic acid; after 21 days of treatment, the plant material was extracted, Partially purified, and analyzed for enzyme activity. The polyphenol oxidase was extracted and determined for enzyme activity, phenol content, protein concentration as well as functional group determination using FTIR analysis. The polyphenol oxidase activity decreased with an increase in ascorbic acid concentration. The study revealed that the protein content in the Brinjal hybrid variety had a maximum of 221 µg/ml, whereas the wild brinjal variety possesses 180 µg /ml. The phenolic content of the hybrid Brinjal variety was found to be 67...

The present study was aimed to evaluate the effect of Piperine on the antidiarrhoeal activity of Diphenoxylate. Antidiarrhoeal effect of Diphenoxylate, Piperine and Diphenoxylate in combination with Piperine was subjected to pharmacological evaluation. Antidiarrhoeal effect was evaluated in castor oil and magnesium sulphate induced diarrhoea model while antimotility and antisecretory effect was evaluated in charcoal meal test and castor oil-induced intestinal secretions in mice. Diphenoxylate at a dose of 1 mg/kg produced 43% and 37.71% inhibition of diarrhoea in castor oil and magnesium sulphate induced diarrhoea model respectively. Diphenoxylate at a dose of 1 mg/kg produced 18.47% antimotility effect and 35.79% antisecretory effect. Piperine at a dose of 10 mg/kg showed 18.89% and 20.72% antidiarrhoeal effect in castor oil and magnesium sulphate induced diarrhoea model respectively. Piperine at a dose of 10 mg/kg produced an 11.55% antimotility effect and 27.65% antisecretory effect. Diphenoxylate (1 mg/kg) with Piperine (10 mg/kg) produced 82.48% and 81.20% inhibition of diarrhoea in castor oil and magnesium sulphate induced diarrhoea model respectively. Diphenoxylate (1 mg/kg)...

Oral squamous cell carcinoma (OSCC) is the most commonly occurring malignancy of the oral cavity. Over the years, the incidence and morbidity rate of Oral Cancer patients has increased worldwide. In the last few decades, although oral cancer treatment modalities have advanced, the survival rate of oral cancer patients is very low. Thus, there arises a need for the identification of new drug targets besides the development of new and effective drugs for this disease. This paper describes the development of Quantitative Structure-Activity Relationship (QSAR) models using machine learning techniques such as Multiple Linear Regression (MLR), k-Nearest Neighbor (kNN), and Support Vector Machine (SVM) for predicting the inhibitory activity (IC50) of anti-cancer compounds against HDAC6 protein. After data pre-processing and selection of relevant features, predictive models were developed, and the top two best performing models were selected based on the parameters such as Squared Correlation Coefficient (r2) and Mean Absolute Error (MAE). Moreover, based on this study, an open-source platform (www.inhibpred.com) has been developed, thus facilitating the identification of...

New pharmacologically active transition metal complexes of Co(II), Ni (II), Cu (II), and Zn(II) have been synthesized with the ligand 5-(2-(4-methoxyphenyl)-1H-benzo [d] imidazol-1-yl) quinolin-8-ol (2). Different analytical and spectroscopic tools were used to analyze the compounds, including elemental analysis, FTIR, 1H-NMR, mass spectra, electronic spectra, magnetic measurement, and molar conductance techniques. FTIR confirmed that the ligand coordinates the metal ion to form a mononuclear complex via the oxygen and nitrogen atoms of the phenolic and quinoline rings. For Co(II) and Zn(II) complexes, tetrahedral geometry is recommended, whereas square-planar geometry is proposed for Ni(II) and Cu(II) complexes. The antibacterial activity of the ligand and its metal complexes were assessed using the disc diffusion method, and minimum inhibitory concentration (MIC) was determined in the broth dilution technique. The antimicrobial activity results showed that the metal complexes were shown to be more active than the free ligand. Besides, Cu(II) complex was shown to be the most potent antioxidant using the DPPH and hydroxyl radical scavenging methods, with IC50 values of 17.3 and...

Niosomes are vesicular carriers in the drug delivery system that are reported in the seventies. They are formed by self -assembly of non –ionic surfactant and cholesterol upon hydration with aqueous media resulting in lamellar structures that encapsulates both polar and non polar drugs. In the present research work, Montelukast sodium niosomes were prepared by using non –ionic surfactant span 60 and cholesterol in 1:1 concentration by thin-film hydration method using a rotary vacuum evaporator. The prepared Montelukast sodium niosomes were incorporated into the nanogel prepared by varying concentration of carbopol 934 to check the effect of polymer concentration on gel property. Niosomal gels were optimized and evaluated for various parameters such as homogeneity, grittiness, pH, viscosity, spreadability, extrudability drug content, skin irritation, in-vitro diffusion, zeta size, zeta potential, Etem study for vesicle size and stability study. Nanogel was successfully formulated by using Montelukast sodium niosome dispersion. The average sizes of niosome vesicles were found to be 496.2 nm, and polydispersity index (PI) was found to be 0.680, zeta...
