A simple, precise yet novel UV spectrophotometric method has been developed for the simultaneous estimation of luliconazole and eugenol. Two methods, namely the simultaneous equation method and the absorbance ratio method were tried for simultaneous analysis. Since the simultaneous equation method gave the best recovery; the simultaneous method was developed for the estimation of both drugs. The wavelength of interest is the wavelength maxima of both drugs; λmax of luliconazole 296 nm and λmax of eugenol 282 nm. The correlation coefficient value (r2) was found to be 0.99 for linearity studies both in methanol and phosphate buffer. Validation studies of the developed method were conducted as per ICH guidelines. The method was precise since the percent relative standard deviation was less than 2 and accurate since the percent recovery was between 99.42% and 105.16%. The developed method can be further used for simultaneous analysis of the drugs in bulk and formulation by UV spectroscopy. The development of a suitable analytical method for quantitative estimation is essential for assay and...

Fungal infections represent a significant global challenge within the realm of dermatology. The prevalence of fungal infections is notably high, affecting approximately 40 million individuals in developing and underdeveloped countries. Considering this, our study proposes a novel approach: transdermal drug delivery utilizing herbal formulations to enhance efficacy & minimize side effects in the treatment of fungal infections. Seven Ayurveda plants extracts were selected & formulated in a 1:1 ratio. These herbal formulations were incorporated into dermal patches composed of HPMC& PEG. Subsequently, the herbal transdermal patch was subjected to characterization like UV spectrometry, folding endurance, thickness measurement, & surface pH determination. The antifungal property of these patches was evaluated against Candida albicans by determining MIC and Agar Well method. The prepared patches exhibited distinctive UV-visible spectra within the 200-800 nm range for the HPMC-based, displayed a thickness of 0.063 ± 0.01, a weight of 206 ± 5.1 mg, and a surface pH of 5.7. The transdermal drug delivery system demonstrated potent fungal inhibition at a concentration of 2.5 mg/ml,...

Celiac disease is a multisystem immune based disorder that is triggered by the ingestion of gluten in genetically susceptible individuals. Our study was limited to a survey of the prevalence of Celiac disease in adult in two Syrian governorates (Homs and Tartous), Statistics were collected from hospitals and clinics of gastroenterologists and nutritionists, during the period of 2014-2022. 4000 cases of Celiac disease were recorded in these two Syrian governorates with a population of about 5 million people with ages ranging from 20-33, that is 0.08% in these cases. The presence of HLA class II antigens was observed in all people with Celiac disease as HLA DQ2 was found in 82% of celiac disease patients, and HLA DQ8 was found in the rest. It is very important that follow-up showed that the results of antibody tests (Transglutaminase IgA) in patients adhering to the gluten-free diet decreased from 200 to 100 “during a year of treatment” and to 20 “during two years of treatment” in all patients. The decrease in...

The study was carried out to isolate and characterize pigment producing bacteria from rhizosphere soil. In our study, isolation and characterization of bacteria that produced pigments were performed using serial dilution, spread plating method followed by gram staining and various other biochemical tests (Oxidase, Catalase and IMViC tests). Our study concluded that bacteria isolated from rhizosphere soil are capable of producing pigment which is flexirubin (light orange in colour) and the bacterium belongs to the genus Chryseobacterium. After extracting the pigment, antimicrobial activity was performed, and it showed that the pigment has antimicrobial activity against both bacteria (E. coli and B. sphaericus) and fungi (Candida albicans). At 100µg/ml concentration, the pigment showed highest antioxidant activity with an absorbance of 0.116AU. The anti-inflammatory activity of the pigment was found to be highest at 1200µg/ml with an absorbance of 0.128AU. It is found that the pigment has the ability to increase SPF property of commercially available sunscreen by 0.713%. Thus different potentials of the pigment can be applicable in various industrial...

Background: NCp7 is a nucleocapsid protein of HIV-1, a retrovirus causing AIDS in human beings. It is a small protein of 72 amino acids that plays an important role in being a chaperone protein involved in viral development. HIV has shown resistance to drugs engineered to treat its infections. Objectives: In this study, a Structure-Activity Relationship analysis of two distinct derivatives based on point pharmacophore was carried out to obtain an NCp7 inhibitor of better performance. Materials and Methods: A Pharmacophore and 3D-QSAR modeling of Pyridinioalkanoyl thioesters and Benzamide-based thiolcarbamates derivatives was performed. Results: A four-point hypothesis of HHRR pharmacophoric feature was determined. A 3D-QSAR model was built which was validated through regression analysis. Molecular docking often lead compounds showed that the compound ZINC65398698 possesses a higher affinity towards NCp7 protein and binds well whereas other leads possessed only moderate binding affinity. The ADME/T prediction of all the ten lead compounds showed accepted values of biophysical properties. As ZINC65398698 showed higher binding affinity, a molecular dynamics simulation was performed...
