Introduction: Padikara Parpam (PP), is one among the highly regarded Siddha medicine that is been traditionally claimed for its anti-proliferating and anti-carcinogenic properties. Objectives: In the present work, we investigated the cytotoxic effects of PP in a cellular model of Human leukemia (Human monocytic cell lines (THP-1). Materials and Methods: Determination of cell viability was assessed by the 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyl-tetrazolium bromide (MTT) assay and by using Confocal Laser Scanning Microscope (CLSM). Fluorescence-activated single cell sorting (FACS), and 2'-7'-Dichloro-Dihydro-Fluorescein Diacetate (DCFH-DA) mediated intracellular Reactive Oxygen Species (ROS) measurements were also carried out to understand the effect of PP on THP-1 cells. Results: PP induced cytotoxic effects against THP-1 in a concentration-dependent manner (6.02%–92.7%), with the highest cytotoxicity at 0.5 mg/mL concentration of PP. The IC 50 values of PP in THP-1 cell lines were 0.115 mg/mL. The result from the MTT assay was further confirmed by CLSM reports. The images of Acridine orange/Ethidium bromide stained THP-1 cells treated with PP (IC 50 concentration) indicated red fluorescence compared to the control cells which showed only green fluorescence. The images indicated the induction of apoptosis by the study drug. FACS and DCFH-DA based intracellular ROS measurements indicated the ability of PP to increase intracellular ROS levels in a concentration dependent manner. Thereby indicating at a possible ROS mediated apoptotic mechanism of action. Conclusion: These results suggest that with further clinical studies, PP could be used as an economic and effective anti-leukemic drug in patients suffering from leukemia.

Background: This study is aimed to develop a validated stability-indicating method of a nasal decongestant phenylephrine hydrochloride in bulk and tablet. Materials and Methods: A sensitive, accurate, and specific reversed-phase stability indicating HPLC method was developed and validated by following ICH guidelines, for the estimation of Phenylephrine Hydrochloride (PHE) in bulk and tablet. On Luna® 5µm C 18 column (250 × 4.6mm), the isocratic separation was achieved using mobile phase of 5mM ammonium acetate (pH 4.7): methanol (80:20; v/v) with a flow rate of 1 mL/min and a column temperature at 30°C. The proposed method was able to produce good separation of the drug and its degradation products with sharp peaks. The quantification was done at 272 nm by photodiode array detection. Conclusion: It was discovered that the phenylephrine hydrochloride was resilient to photolytic and thermal degradation, but degraded under acid, base, and oxidative stress conditions. The developed method was found to be linear, robust, and accurate and can be successfully applied for identification, quantitative determination, and monitoring of the stability of phenylephrine in bulk and tablet dosage forms.

Background and Aim: Based on inhibitors of DPP-IV, there is a fantastic method for creating anti-diabetic medications. These inhibitors regulate diabetic patients' blood sugar levels to prevent difficulties with their health. In the current work, we created a brand-new series of compounds Cyclopyrrolidine clubbed with oxadiazole bases. Materials and Methods: Cyclopyrrolidine clubbed with oxadiazole bases (B-1 to B-16) were synthesized and characterized through IR, NMR, mass spectrometry, and elemental analysis. Docking studies were performed to assess interactions and binding modes of synthesized hits at the binding site of receptor DPP-4 (PDB 3W2T). Using vildagliptin as a standard drug, six of the synthesized compounds were tested for their antidiabetic activity in diabetic rats induced with HFD-STZ-Nicotinamide. Results: The results showed that compound B-XIV (220*4.56B) resulted in the greatest reduction in blood glucose level from all synthesized compounds compared to that of vildagliptin (215*7.52B) in HFD-STZ-Nicotinamide. Other compounds showed moderate to good antihyperglycemic activity. Conclusion: From he presents work it can be concluded that synthesized compounds possess good DPP-IV inhibitory activity. Compounds containing electron-withdrawing groups (chlorine, nitro, methoxy) were displayed a good anti-diabetic effect than electron-donating groups (methyl, hydroxyl). Oxadiazole derivatives could be used for further development to obtain more promising drug candidates.

Aim/Background: Analytical Quality by Design refers to applying the Quality by Design idea to the development of analytical procedures. The present study emphasizes the AQbD concept of developing and validating a spectrophotometric technique for detecting α, β-arteether per the ICH Q8 ( R 2 ) requirements for the first time. Materials and Methods: Sample preparation, sample pH, and wavelength were all integrated into the Ishikawa diagram, and essential parameters were obtained. The ratio of ethanolic PBS 6.8 and HCl was taken as factors. At the same time, the drug molecule's absorbance was identified as a critical factor that was further analyzed using a simple mixture design of experiments methodology for method robustness and optimization. The novel, durable, precise, and accurate UV-spectrophotometric method, α, β-arteether, was developed using the Quality by Design principle. By adjusting the HCl concentration (for acid degradation) and ethanolic PBS 6.8, the highest absorption of α, β-arteether was achieved by heating at 50°C for 30 min. Results and Discussion: The percent RSD less than 2, R 2 > 0.99 was recorded for the concentration range of 2–20 μg/mL at λ max 254 nm. The developed method's LOD and LOQ were within acceptable limits. The presented approach might be used at the industrial level as a rapid, precise, accurate, and cost-effective quality control method for a frequent and simultaneous estimate of α, β-arteether.

Introduction: Tetrahydrocurcumin (THC) is a partially reduced white metabolite of curcumin which does not impart yellowish colour on skin due to which it seemed to be a promising topical agent compared to curcumin which discoloured the skin with long lasting visible mark. Objectives: The research work was intended to formulate THC loaded Nano Lipid-based (TNL) Carbopol Gum Gel (TNLCG) also called tetrahydro curcumin nanoemulgel and to investigate its therapeutic efficacy against inflammation using animal model. Materials and Methods: TNLCG was prepared based on pseudoternary phase-diagram with solubilizing capacity of tocopheryl acetate (10% w/w) and emulsifying combination of tween 80: polyethylene-glycol 400 (2:1 in 35% w/w) in 45% w/w aqueous phase with Carbopol 934 gel base. Selected formulations were evaluated for various parameters using in-house developed HPLC analytical method (at 280nm). Results: Nanoemulgel was found to be a stable formulation which significantly improved cellular absorbency with tocopheryl acetate with high concentration of THC for treating skin inflammation. Significant increase in the steady state flux (Jss) of 41µg/cm 2 /h, permeability coefficient (Kp) of 1.08 and Enhancement ratio (Er) of 3.7 were observed. The TNLCG demonstrated 77.36% in vitro drug release, significant skin permeability and optimal properties including spherical shape with 129nm nanosize, adequate zeta potential (-21.45mV), and PDI value of 0.18. Conclusion: This study revealed encouraging outcomes for TNLCG formulation as a novel tool for safe delivery of THC. According to the findings of the preceding research, it can be an effective therapeutic formulation which offers significant inflammation reducing activity with good moisturising quality.
