The Philippine archipelago is rich in marine biodiversity and resources that are widely unexplored. Its marine sediments harbor marine microbes that possess secondary metabolites with potent bioactivities. This study aims to determine the antiproliferative activity of the crude extracts of selected Actinomycete isolates (DSD011, DSD017, and DSD042) from Islas de Gigantes, Carles, Iloilo. The antiproliferative screening was done using Saccharomyces cerevisiae as a model organism. Crude extracts of isolates that are active in inhibiting the growth of S. cerevisiae were determined using the broth microdilution method. Afterward, the active extract was tested using antiproliferative and budding yeast assays. With the …

Breast cancer is one of deadliest diseases in world. Turmeric extract was known to have antiproliferative activity. To minimize its toxicity, turmeric extract was encapsulated with liposome, a vesicle lipid bilayer functioned as cancer drug carrier in body. This research aimed to determine encapsulation effect of turmeric ethanol extract against antiproliferative activity in T47D breast cancer cells through in vitro assay. Liposomes was made using thin layer method and particle size was reduced by extrusion. Materials used are phosphatidylcholine, cholesterol, and turmeric extract. Optimization of liposomes was made in three formulations with different concentrations of extract. Most optimal formulation was …
