The Thai Journal of Pharmaceutical Sciences

Vitex glabrata (VG) or Khai-noa fruit extracts were prepared from three methods; squeezing extract (SE), maceration extract (ME), and ethanol extraction (EE) to evaluate their effects in vitro. By the (1,1-diphenyl-2-picrylhydrazyl) scavenging assay, all extracts revealed very weak antioxidant. Results of (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide, a tetrazole) assay showed the increase in cell viability of SE at 100 and 500 μg/ml on TK6 cells after 24 and 48 h treatments (P < 0.01) without affecting Caco-2 cells. Conversely, a dose- and time-dependent cytotoxicity of all extracts revealed at 1000-2000 μg/ml on both cells (P < 0.01). SE showed cytotoxicity on PC-3 cells and anticancer activity when confirmed by clonogenic assay in a dose-dependent manner. SE also showed cytotoxicity on HT-29 cells after 24 h treatment but the cells could recurrent in the clonogenic assay. No effect was observed on MCF-7 cells after SE alone, SE co-treated with MMC treatment, and in the clonogenic assay. Moreover, HT-29 cells revealed a dose-dependent decrease in viability when treated with SE co-treated with MMC by 24 h. Hence, SE can selectively promote cell viability on TK6 and anticancer activity on PC-3. These results suggest that the different potential of SE depends on different cell lines.

The Thai Journal of Pharmaceutical Sciences

Objectives: The pharmacological basis of anti-inflammatory agents is geared toward maintaining body homeostasis. This study investigated the scientific underpinning and mechanisms of anti-inflammatory activity of root bark of Brenania brieyi. Material and Methods: The plant material was extracted with a mixture of methanol and chloroform (2:1) and fractionated with 0.2 volume water. Egg albumin-induced edema and cotton pellet-induced granuloma models were used to investigate anti-inflammatory activity while the possible mechanisms of actions were evaluated using standard methods. Results: Significant (P < 0.05) reduction in edema and granuloma tissue formation were recorded in fractions treated groups compared with the normal control. There was a significant (P < 0.05) inhibition of membrane hemolysis and phospholipase A2 (PLA2) activity by the fractions compared with the standard drugs, indomethacin, and prednisolone, respectively. Both fractions significantly (P < 0.05) inhibited prostaglandin (PG) synthase and nitric oxide radical activities compared with the control. However, varying doses of both fractions did not inhibit leukocyte migration compared with rats in indomethacin and control groups. The methanol fraction was found to be more potent in most of the tests. Conclusion: These results show that B. brieyi root bark has anti-inflammatory activity, and the potential underlying mechanisms of its action are inhibition of PLA2 and PG involved in inflammatory responses.

Curcumin-loaded liposomes comprising dipalmitoylphosphatidylcholine, cholesterol, and dioleoylphosphatidylethanolamine (72:8:20 mole ratio) were prepared by the thin-film hydration method, followed by probe sonication to achieve a mean diameter (FSI) pre-cooled at 2–8°C for at least 90 min at 15 L/min. Curcumin recovered from the impactor and nebulizer was quantified using a validated high-performance liquid chromatography method. Overall, 2.5% w/w curcumin-loaded liposomes was the optimal formulation based on the maximum encapsulation efficiency of approximately 87% and mean hydrodynamic diameter of 97 nm. This chosen curcumin concentration was effectively aerosolized with a fine particle fraction of 53.25%, and a fine particle dose of 53 …
