Cytotoxic Effect Of Crude Vitex Glabrata Fruit Extracts On Human Cancer Cell Lines, Saraphorn Intarasam, Vorranuch Keerathinant, Mesayamas Kongsema, Kantimanee Pradermwong Jan 2022

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.

The Thai Journal of Pharmaceutical Sciences

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 …

The Thai Journal of Pharmaceutical Sciences

Objective: This research developed a notification intravenous-to-oral antibiotic switch therapy system using value stream mapping (VSM) through the Plan-Do-Study-Act (PDSA) method. Materials and Methods: The action research took place in two target groups: Group 1 included a multidisciplinary team and Group 2 included pneumonia patients admitted to two pediatric wards. The system had two phases: In Phase I, Situation analysis reviewed 400 medical records and In Phase II, a system was developed that used PDSA as follows: Plan: analysis of the methods. Do: The demonstrated process used VSM. Study: A system designed. Act: Comparing each step used VSM. The system …

The Thai Journal of Pharmaceutical Sciences

Objective: The present study investigated the antibacterial activities of asam gelugur (Garcinia atroviridis) fruit extracts against two Gram-negative bacterial strains (Escherichia coli (gi: CP033762.1) and Salmonella enterica (gi: KX355299.1)). Materials and Methods: The powder form of G. atroviridis fresh fruit was extracted with 95% ethanol (2:4 L) (w/v). The mixtures were filtered and evaporated using a rotary evaporator at 50–55°C. High-performance liquid chromatography (HPLC) was used to measure hydroxycitric acid (HCA) in the extract. The antibacterial assay was determined by disk diffusion method, the minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC). Results: HPLC analysis measured approximately 495.01 ± …
