The Thai Journal of Pharmaceutical Sciences
In the past decades, with substantial growth of pharmaceutical companies and the need in enhancement of quality paradigms, adoption of systematic science based technologies was an inherent demand of regulatory agencies and one such technology is quality by design (QbD). The approved interrelated International Council on Harmonization of Technical Requirements for pharmaceuticals for Human Use guidelines, Q8 (pharmaceutical development), Q9 (quality risk management [QRM]), and Q10 (pharmaceutical quality system) drove the path in successful implementation of QbD. The primary focus of this article is made in delivering the underlying concepts that lead in framing of seven vital elements of QbD. …

The Thai Journal of Pharmaceutical Sciences
This study aimed to synthesize a poly(ethylene glycol) diacrylate-modified chitosan (CS-PEGDA) as a mucoadhesive polymer for transmucosal drug delivery. Chitosan-cysteine (Cys-CS) was synthesized by coupling chemistry. Cys-CS was then employed for the synthesis of CS-PEGDA through a thiol-ene click reaction between the thiol groups of Cys-CS and alkene groups of PEGDA using triethanolamine as an activator. The obtained structure of the synthesized polymer was proved using Fourier transform infrared (FT-IR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy. The mucoadhesive capability of the synthesized polymer was examined by an ex vivo mucoadhesion test using a texture analyzer. The toxicity of synthesized …

The Thai Journal of Pharmaceutical Sciences
Lasianthus stipularis Blume is a medicinal plant found in the tropical rainforests of peninsular Thailand and Malaysia. Its leaves are used in traditional medicine to treat a condition called “noise in the head” (i.e., ear infections). As such infections are often caused by Gram-negative bacteria; this species of Lasianthus may have antibacterial effects. In this study, we examined the non-polar fractions from the leaves and stem bark of L. stipularis using thin-layer chromatography and high-performance liquid chromatography (HPLC). The non-polar fractions exhibited a high coumarin content, while stem bark extracts showed a high concentration of 7-hydroxy-6-methoxycoumarin when isolated by column …

Effect Of Co2 Laser Irradiation On Eudragit® L100-55, L100, And S100 Coatings To Modify Drug Release, Varin Titapiwatanakun, Wanjing Li, Simon Gaisford, Abdul W. Basit
The Thai Journal of Pharmaceutical Sciences
The aim of this work was to investigate the use of carbon dioxide (CO2) laser irradiation to modify three types of pH-dependent Eudragit® (L100-55, L100, and S100) enteric coats with the aim of modulating drug release kinetics from the tablet cores. CO2 laser irradiation causes rapid melting and resolidification/vaporization of materials locally and precisely through the absorption of infrared energy and so can potentially disrupt the barrier integrity and function of enteric coats. It was successfully utilized to shorten the lag time of drug release (T50% and T80%) during dissolution testing. These changes were mainly caused either by pore formation …

Group-Based Quantitative Structure And Activity Relationship On Benzothiazole Derivatives For Development Of Potent Anti-Cancer Compounds, Amit S. Tapkir, Sohan S. Chitlange, Ritesh P. Bhole
The Thai Journal of Pharmaceutical Sciences
To develop potent anticancer compounds using benzothiazole scaffolds group-based quantitative structure and activity relationship (GQSAR) analysis was performed on 41 reported benzothiazole derivatives for identification of structural fragments. Benzothiazole dataset was fragmented into two fragments (R1 and R2). GQSAR models were generated using multiple linear regression. GQSAR analysis revealed the presence of hydrophobic groups on R1 will potentiate anticancer activity. The generated models are giving insight into the benzothiazole structural requirements which will be optimized for design of anticancer drugs.

A new series of 1,3,4-oxadiazole derivatives (3a-j) were synthesized by reacting p-toluic benzhydrazide (1) and substituted aromatic aldehydes (2) in the presence of ceric ammonium nitrate as catalyst and dichloromethane as a solvent medium. The structures of the new compounds were assigned based on IR, 1H-NMR, and mass spectral data and further evaluated for their in vitro anti-inflammatory potential using various protein denaturation methods following bovine serum and egg albumin assay. Some tested compounds 3e, 3f, and 3i displayed moderate anti-inflammatory activity compared to the standard diclofenac sodium.

The Thai Journal of Pharmaceutical Sciences
For the assessment of the curative effect of Manosa alliacea on Freud’s adjuvant (FA) arthritis on Swiss albino rats. Methanol extract from M. alliacea (MEMA) was administered orally at 200 mg/kg and 400 mg/kg, 28 days after FA immunization. For control and treatment groups, paw volume, body weight, hematological parameters, X-ray, and histological tests were measured. In addition, reverse transcription-polymerase chain reaction (RT-PCR) was used to measure the levels of various inflammatory markers. In vitro, DPPH and H2O2 tests were used to evaluate the antioxidant capability. MEMA decreased paw volume and paw thickness, bodyweight considerably (P < 0.05, 0.01, 0.001), compared to hematological anomalies of arthritis control. X- rays tests and histological tests did not reveal significant structural changes in the rat ankle joints administered with MEMA. The levels of expression tumor necrosis factor - α, NF-Kβ, IL-1β, and COX-2 were significantly suppressed in the treatment groups. The in-silico study has shown that a number of chemical components in the plants under study can effectively bind to various inflammatory targets. That is why we say M. alliacea is a good source for treating rheumatoid arthritis.
