The Thai Journal of Pharmaceutical Sciences

In the work presented, an high-performance liquid chromatography method was developed and validated for the estimation of seratrodast (SER) in spiked human plasma, using flurbiprofen as an internal standard (IS). The drug and IS were extracted from pooled human plasma sample using 5 mL of tert-butyl methyl ether with 200 μL of 1% v/v formic acid. Both SER and IS were well separated and resolved from each other and plasma interferents using 20 mM phosphate buffer (pH 3.0) with acetonitrile in the proportion of 30: 70% v/v, in an isocratic mode at 1 mL/min on a C18 column and detection …

The Thai Journal of Pharmaceutical Sciences

The present study investigated the phytochemical, high-performance thin-layer chromatography (HPTLC) profiling, total phenolic content, antibacterial activity, acute toxicity studies, hemodynamic parameters, myeloperoxidase (MPO) activity and serum procalcitonin (PCT) levels of hydroalcoholic extract of Bryum weigelii (HE-Bw), and its effects on cecal ligation and puncture (CLP) induced sepsis in mice. The preliminary phytochemical screening showed that HE-Bw contains alkaloids, terpenoids, flavonoids, phenolics, and tannins. The HPTLC analysis of HE-Bw identified three unknown components with different Rf values and area percentage. The total phenolic amount for HE-Bw was equivalent to 211.6 ± 0.8 mg of gallic acid per 100 g of dried …

The Thai Journal of Pharmaceutical Sciences

Synthetic cannabinoids are currently the largest group of new psychoactive substances. Among them, one of the most recent compounds in Vietnam is AMB-Fubinaca. No quantitative method has been officially implied for AMB-Fubinaca in criminal evidences, thus, making the police investigations burdensome. This study, for the 1st time, aimed to develop and validate the gas chromatography with flame ionization detector (GC-FID) method to determine and quantify AMB-Fubinaca in criminal evidences found in the South of Vietnam from 2016 to 2018. Chromatography separation was achieved on diphenyl dimethyl polysiloxane GC column (30 m × 0.32 mm × 0.25 μm) with a total …

Effect Of The Hydrophilic-Lipophilic Balance Values Of Non-Ionic Surfactants On Size And Size Distribution And Stability Of Oil/Water Soybean Oil Nanoemulsions, Kamonwan Singpanna, Dusadee Charnvanich

The Thai Journal of Pharmaceutical Sciences

Objective: This study aims at investigating the effect of the hydrophilic-lipophilic balance (HLB) of non-ionic surfactants on physical property and stability of nanoemulsions. Materials and Methods: The nanoemulsions were prepared using the Microfluidizer. The oil phase consisted of 10% w/w soybean oil and 5% w/w surfactant(s). Types of nanoemulsions were confirmed by dilution test. The average droplet size and size distribution (polydispersity index [PDI]) were measured by dynamic light scattering Zetasizer Nano ZS™. The screening physical stability was done by centrifugation. Only the formulations with no phase separation were further evaluated for physical stability. Results: All nanoemulsions were single phase …

Systematic Development By The Design-Of-Experiment Approach And Physicochemical Evaluations Of The Optimized Self-Microemulsifying Astaxanthin Delivery System, Mo Mo Ko Zin, Veerakiet Boonkanokwong

The Thai Journal of Pharmaceutical Sciences

A self-microemulsifying delivery system (SMEDS) containing astaxanthin (AST) was developed and optimized using a mixture design and its desirability function. Independent factors studied in the experimental design were the amounts of castor oil, Cremophor® RH 40, and Tween® 80 in a formula. The measured response variables included droplet size, polydispersity index (PDI), zeta potential, active ingredient content, and transmittance of microemulsions obtained from the AST SMEDS formulations. The desirability function was then adjusted to optimize the formulation. The optimized AST SMEDS was composted of 19.59% castor oil, 62.34% Cremophor® RH 40, and 18.03% Tween® 80, and the resulting self microemulsions …

The Thai Journal of Pharmaceutical Sciences

Hyptolide and epoxy hyptolide were successfully isolated and synthesized from Hyptis pectinata extract that potential to cure malaria diseases. The previous studies showed that these compounds contained lactone groups associated with antibacterial and anticancer activities. However, the antimalarial activity remained unclear. This study aimed to investigate the antiplasmodial activity of H. pectinata extract, hyptolide, and epoxy hyptolide. These compounds were tested in vitro for antiplasmodial activity against chloroquinesensitive 3D7 strain of Plasmodium falciparum. Thin blood smears were used to assess the levels of parasitemia and growth inhibition of the isolates and the ClpP inhibition was analyzed under well diffusion assay. …

Novel Mechanistic Insights Towards The Repositioning Of Alogliptin In Parkinson's Disease, Eman Ramadan, Marwa M. Safar

Pharmacy

Parkinson's disease (PD) is a progressive neurodegenerative disease that impairs people's lives tremendously. The development of innovative treatment modalities for PD is a significant unmet medical need. The critical function of glucagon-like peptide-1 (GLP-1) in neurodegenerative diseases has raised impetus in investigating the repositioning of a dipeptidyl peptidase IV inhibitor, alogliptin (ALO), as an effective treatment for PD. As a result, the focus of this research was to assess the effect of ALO in a rat rotenone (ROT) model of PD. For 21 days, ROT (1.5 mg/kg) was delivered subcutaneously every other day. ALO (30 mg/kg/day), delivered by gavage for …

Analysis Of Hba1c, Medication Compliance, Income Subsidies, And Comorbidity In Medicare Type 2 Diabetics, Robert E. Lazarchik

Walden Dissertations and Doctoral Studies

Diabetes is one of America’s leading chronic diseases with comorbidities contributing to lower health statuses and increased health care costs. While it is known that lowering HbA1c reduces the deleterious effects of diabetes, the capability to identify people with diabetes at risk for uncontrolled HbA1c levels or developing comorbidities based on the compliance rates for different oral antihyperglycemic medication classes (OAMCs) and financial assistance programs does not yet exist. These quantitative longitudinal retrospective studies examined the association between medication compliance, using Proportion of Days Covered (PDC), by OAMC and Medicare financial aid programs, on predicting HbA1c levels and comorbidities in …

The Thai Journal of Pharmaceutical Sciences

Objective: The purpose of this study is to evaluate the role of farnesol as a potential neuroprotective agent against 3-nitropropionic acid (3-NP) acid-induced Huntington’s disease (HD) by in vitro, in vivo, and in silico models. 3-NP acid-induced Huntington’s disease in male Wistar rats was used to evaluate the neuroprotective potential of farnesol. Materials and Methods: 3-NP (10 mg/kg/day) was used for the induction of disease, followed by treatment with 50 mg/kg and 100 mg/kg of farnesol for 7 days. The effect of farnesol on motor symptoms was evaluated using actophotometer and rotarod apparatus and effect of farnesol on learning and …

Morphological Changes In Dorsal Root Ganglia Macrophages Associated With Neuropathic Pain Mechanisms Suggest A Novel Target For Chronic Pain Therapy, Emily Kussick

CMC Senior Theses

The present study examined morphological changes in the dorsal root ganglia (DRG) following an innate immune stimulus. The importance of the DRG has increasingly become recognized in pain processing as more than just the home of primary afferent cell bodies. All sensory information passes through the DRG via the primary afferents, and on to the spinal cord. The primary afferents synapse with second-order neurons in the spinal cord that ascend towards the brain, where they transmit the pain signal to the limbic forebrain and/or the somatosensory cortex for processing. The DRG is an interesting niche to study at as it …

Human Regulatory T Cells Control Inflammation From Effector T Cells In Prediabetes, Rui Liu

Theses and Dissertations--Pharmacy

Type 2 diabetes (T2D) is a chronic low-grade inflammatory disease. A T cell cytokine profile (Th17) from PBMCs can distinguish obese T2D from obese non-diabetes subjects. Individual T cell subsets interact with each other and the diverse subsets jointly determine overall inflammation. Cellular metabolism drives cytokine production of CD4⁺ T cells, and therefore contributes to inflammation in T2D. However, specific changes in metabolism and function of CD4⁺ T cells during the progression from lean healthy to obese and diabetic stages in people have not been clarified.

We hypothesize that human regulatory T cells (Treg) impact metabolism of effector …
