2023-10-17T07:11:23+00:00

Ketoconazole is a weakly basic drug that has lower solubility at higher pH. Determination of solubility of ketoconazole in the base solution is not easy due to the poor solubility. The simple, low cost, efficient, accurate spectrophotometry methods in UV/VIS region have been developed for the determination of ketoconazole. The wavelengths were selected at 230 nm using solvent buffer phosphate pH 6.8. The Beers’ law was obeyed in the concentration range 5-50 ppm. According to ICH guidelines the parameters such as linearity, accuracy, precision, the limit of detection, and the limit of quantification were studied. The regression equation of calibration curve was found to be y=0.0448x-0.13. All concentrations were linear, with the absorbance having a correlation coefficient 0.9994. The accuracy was found between 93.84-95.95%. The % Relative Standard Deviation (RSD) of Ketoconazole was found to be 0.112-1.237 for intraday and 0.008-0.792 for interday precision. The result of the limit of detection (LoD) for ketoconazole was 0.988 that could be reliably detected and the limit of quantification (LoQ) for ketoconazole was 3.294 ppm. The result of ketoconazole solubility was 21.044±0.759 ppm that indicating ketoconazole was a poorly soluble drug in the intestine. The proposed methods could be applied to the determination solublity ketoconazole in buffer phosphate pH 6.8 with good accuracy, good precise, and simple.

2023-10-18T06:34:54+00:00

Urolithiasis is a form of urinary system disease in which kidney stones develop when minerals are got deposited in renal, urinary bladder, and ureters. Twelve percent of the world's population is impacted by it. Long-term kidney stone deposition harms healthy kidney cells by generating free radicals. Because chia seeds (Salvia hispanica) have the best anti-oxidant activity, the current study's objective was to assess the anti-urolithiatic activity of the methanol extract of these seeds using an in-vivo approach on a rat model of urolithiasis induced by ethylene glycol (EG). The extract was prepared by macerating it with 100% methanol. An in-vivo investigation was performed on rats, where rats were split into six groups, and each group had six rats (n=6). Group-1 kept as a vehicle control (normal control), group-2 was a disease control group (EG 0.75% v/v), group-3 was named as reference group receiving Cystone^® 750 mg/kg, groups from 4 to 6 were groups receiving treatment, and receiving different doses of the extract at 100 mg/kg, 300 mg/kg, and 700 mg/kg, orally for 21 days. The in-vivo anti-urolithiatic analysis of the extract revealed significant increase (p 0.001) in urinary magnesium levels, urine volumes, kidney and body weights while significant decreases (p 0.001) were seen in urine parameters (such as oxalate, calcium, phosphate, sodium, and potassium) and serum parameters (such as uric acid, blood urea nitrogen, total proteins, and total albumin). When compared to the normal control group in histology, the disease control group had kidney stones, interstitial inflammation, and cell damage. No toxicity symptoms were noticed in the treatment group at a dosage of 700 mg/kg. Based on in-vivo research using histopathological, urine, and serum data, it can be said that the extract has anti-urolithiatic activity.

Imaging Non-Small Cell Lung Cancer EGFR Del19 and L858R with Radiolabeled Small Molecule

2023-10-21T09:09:49+00:00

Non-Small Cell Lung Cancer (NSCLC) is the leading cause of cancer death with approximately 1.3 million deaths annually worldwide. Tyrosine Kinase Inhibitors (TKIs) targeting the Epidermal Growth Factor Receptor (EGFR) are used as therapy for NSCLC patients. However, patients receiving first and second generation TKIs will usually develop drug resistance within 6-12 months after treatment. Resistance occurs because of EGFR mutations that interfere with the therapeutic process. Therefore, it’s necessary to detect the type of EGFR mutation before treatment by TKIs. Molecular imaging techniques such as Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) are promising non-invasive techniques for the detection of mutation. This study aims to review articles on radiotracers that have been developed to detect common EGFR mutation such as exon 19-del and exon 21 L858R mutation in NSCLC. The method in this research is to search for articles through international database such as Scopus, Scifinder and PubMed with inclusion and exclusion parameters. The results exhibited that several radiotracers were found that were selective for EGFR 19-del and L858R. However, some compounds need to be modified structurally to have high specificity.

Immunosuppressive Effect of Caffeine and Metformin in The Drosophila Model of Autoinflammatory Disease

2023-10-21T09:39:38+00:00

In the quest to find new indications for existing drugs, drug repurposing has emerged as a promising strategy. However, a significant obstacle has been the lack of a robust, high-throughput, in vivo preclinical system suitable for screening and investigating these new uses. This study addresses this challenge by introducing Drosophila larvae as a potential in vivo platform for evaluating drugs with immunomodulatory properties. To determine the suitability of Drosophila larvae for assessing the immunomodulatory effect of drug candidates, we performed phenotypical and molecular assays using two well-known immunomodulatory compounds, caffeine and metformin, that has been previously investigated using mammalian models. Our preliminary results demonstrated that caffeine and metformin were relatively harmless for Drosophila larvae and could improve their lifespan. Further molecular analysis suggested that both caffeine and metformin influenced gene expression in Drosophila larvae, particularly in the NF-κB and JAK-STAT pathways, which are analogous to immune-related pathways in mammals. Both caffeine and metformin showed promising results in the autoinflammatory Drosophila model, indicating a potent immunosuppressive activity. Additional analysis revealed that these compounds did not exhibit antibacterial or immunostimulant properties in the Staphylococcus aureus-infected wildtype and immunodeficient Drosophila. In conclusion, our study suggests that the observed immunosuppressive effects of caffeine and metformin in Drosophila larvae align with those seen in the mammalian models. This study highlights the suitability of Drosophila larvae as a model organism for drug repurposing, especially in the screening of newly discovered chemicals for their immunomodulatory properties before proceeding to mammalian animal models.

Research published in the International Journal of Cardiology in 2008 shows that high uric acid levels can increase levels of bad LDL cholesterol, triglycerides and other blood fats. In addition, another study in 2019 released by Lipids in Health and Disease also stated that in the 3,884 volunteers studied, the risk of developing high uric acid doubled if they had cholesterol triglycerides above the normal threshold. However, the above conditions of complications and decline in health can be suppressed by administering antioxidant supplements. Based on the description above, the combination of kasumba tutareta and seccang has good potential in the development of traditional medicine with claims of reducing uric acid, anti-cholesterol and antioxidant properties. Based on the results of antioxidant research using the FRAP method, it was found that the capacity of antioxidant seccang extract 122,88 mg/g, kasumba turatea extract 17.36 mg/g and a combination (1:1) 197.31 mg/g. From these data it can be seen that the combination of seccang and kasumba turateta extracts has higher activity.

Green extraction and enrichment of natural bioactive compounds: An innovative and economical approach in phytomedicine

2023-10-23T07:50:39+00:00

Natural sources in general and plants in specific are unique supplier of novel bioactive compounds. However, their isolation involves a time-consuming, energy-intensive, multi-stage process that requires a large amount of toxic organic solvents, ultimately increase its production costs. An alternative approach that presents the possibility of synergistic effect is to prepare active constituent’s enriched extract using green extraction approaches with the help of microwave assisted extraction technology and enrichment by using biodegradable resin columns. Recently, berberine rich extract (BRE) has been prepared from Berberis lyceum root bark, having 58% w/w of berberine using microwave and hydrophobic resin Diaion^® HP-20 column. BRE was compared with commercially available pure berberine (more expensive) in various pharmacological models including, antimicrobial (against Proteus vulgaris, P. aeruginosa, Staphylococcus aureus, K. pneumonia, Salmonella typhi and methicillin-resistant staphylococcus aureus (MRSA)), anti-inflammatory (in vitro chemiluminescence technique and in vivo carrageenan and formaldehyde-induced rodent inflammation models), wound healing (cell migration assays), antidiabetic (nicotinamide-streptozotocin induced diabetic rat model), anticancer (A549-lung cancer cell and MDA-MB-231- breast cancer cell lines) and ant-Alzheimer (AlCl₃ induced rat model). In all of the pharmacological models, BRE shows dose dependent, potent and significant bioequivalent effects to pure commercial berberine. The under taken study suggests that BRE can be used as an alternative of berberine.

Renieramycins from Thai blue sponge Xestospongia sp. and their semisynthetic analogs as potential cytotoxic agants against non-small-cell-lung-cancer cell lines

Renieramycins constitute a series of marine alkaloids within the bistetrahydroisoquinolinequinone family, which have been sourced from the Thai blue sponge Xestospongia sp., discovered at Si-Chang Island in the Gulf of Thailand. The chemical configurations of renieramycin A-Y have been documented. Notably, renieramycin M emerges as the principal chemical constituent. Renieramycin M and its semisynthetic analogs, harboring diverse ester substituents at positions C-5, C-7, and C-8 on ring A as well as C-22 on ring B , were synthesized and assessed for their cytotoxicity against non-small-cell-lung-cancer cell lines. The synthesis involved judicious chemical manipulations, encompassing hydrogenation, light-induced intramolecular photoredox reactions, and Steglich esterification. The findings from the investigation into the structure-cytotoxicity relationship imply that an additional ester motif governs cytotoxic efficacy, predicated on steric hindrance. This augmentation significantly enhances nanomolar cytotoxicity levels against H290 and H460 cell lines, surpassing the potency of renieramycin M by a factor of 5-20 folds.
