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.

The Thai Journal of Pharmaceutical Sciences
Pueraria candollei var. mirifica (Airy Shaw & Suvat.) Niyomdham (PM), popularly known as “Kwao Krua,” is a medicinal plant that has been used for centuries in Thailand. Phytochemical studies indicated the presence of several bioactive molecules such as miroestrol, deoxymiroestrol, puerarin, daidzein, daidzin, genistin, genistein, and kwakhurin. The pharmacological evaluation of PM indicated strong estrogenic, anti-osteoporosis effects, anti-aging and antioxidant activities, as well as the ability to relieve other climacteric-related symptoms. There is conflicting evidence on the safety and toxicity of PM. The active ingredients in PM make it an ideal candidate for large-scale pharmaceutical exploitation as a cosmeceutical. Further …

Cytotoxic Effect Of Crude Vitex Glabrata Fruit Extracts On Human Cancer Cell Lines, Saraphorn Intarasam, Vorranuch Keerathinant, Mesayamas Kongsema, Kantimanee Pradermwong
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.

Objective: The objective of the present study is to evaluate the antiulcer property of ethanolic extract of Phyllanthus reticulatus Poir. against pylorus ligation-, ethanol-induced, and stress-induced ulcer models in Wistar albino rats. Materials and Methods: Three models – pylorus ligation-induced ulcer, ethanol-induced ulcer, and swim stress-induced ulcer – were used to induce ulcer in Wistar rats. The animals were treated with 200 mg/kg and 400 mg/kg p. o of the ethanolic extract of P. reticulatus Poir, to estimate the gastroprotective potential. The effect of P. reticulatus Poir. on pH of the gastric juice, volume of acid secretion, total and free …

Introduction: Urea- and thiourea-based compound has shown a potency to be further developed as anticancer compound. Objective: Another novel phenylthiourea analog (N-(2,4-dichloro)benzoyl-N’-phenylthiourea) was synthesized through Schotten-Baumann reaction followed by the assessment of its cytotoxic activity. Methods: N-(2,4-dichloro)benzoyl-N’-phenylthiourea was synthesized using N-Phenylthiourea and 2,4-dichlorobenzoyl chloride as starting materials. The reaction started at low temperature for 30 min followed by reflux for 8 h to yield target compound. Cytotoxicity assay was then performed against MCF-7, T47D, and Vero normal cell line. Results: The compound has been synthesized and its structure has been verified using infrared, 1H-nuclear magnetic resonance (NMR), 13C-NMR, various 2D …

Transdermal drug delivery system networks are primarily affected by poor penetration of therapeutically active compounds. The stratum corneum (SC) is the foremost barrier of the skin, which restricts the permeation of the drug molecule. In this context, to date, numerous approaches have been implemented to overcome the SC barrier limitations. Out of this, few advanced approaches including liposomes, niosomes, ethosomes, and transferosomes are majorly used to boost the permeation of drug and cosmetic agents across the SC barrier. Among these vesicles, ethosomes are stand out as the best substitute for topical drug delivery. In a nutshell, ethosomes are the elastic …

Cadmium accumulates in different organ and tissues of the body including the testes, impeding normal metabolism. This study aimed at evaluating the effect of Plukenetia conophora leaves extract on antioxidants and testicular function indices of cadmium chloride (CdCl2)-administered Wistar rats. A total of 25 Wistar rats (100–120 g) were randomly divided into 5 groups (A-E) and received orally, once daily for 21 d as follows: A (distilled water); B (6.5 mg/kg body weight of CdCl2; C (CdCl2 + 150 mg/kg body weight of extract); D (CdCl2 + 300 mg/kg body weight extract); and E (CdCl2 + 600 mg/kg body weight …

Background: In the present study, a simple, sensitive, rapid, accurate, and precise reverse-phase high-performance liquid chromatography (RP-HPLC) method with diode array detection was developed and validated for simultaneous estimation of Metformin hydrochloride (MET) and Ranolazine (RANO) in a synthetic mixture. Material and Method: The method was developed using isocratic elution mode on a reversed-phase. Chromatographic separation was performed on ACE CN C18 (250 mm, 4.5 mm, 5 μm) column and a mobile phase consisting of methanol: acetonitrile:ammonium formate (45:45:10% v/v/v) with 10% formic acid to adjust the pH to 6.0, at a flow rate of 1.0 ml/min. Detection and quantification …
