Plant-Derived Natural Products in Cancer Research: Extraction, Mechanism of Action, and Drug Formulation.

Abstract: Cancer is one of the main causes of death globally and considered as a major challenge for the public health system. The high toxicity and the lack of selectivity of conventional anticancer therapies make the search for alternative treatments a priority. In this review, we describe the main plant-derived natural products used as anticancer agents. Natural sources, extraction methods, anticancer mechanisms, clinical studies, and pharmaceutical formulation are discussed in this review. Studies covered by this review should provide a solid foundation for researchers and physicians to enhance basic and clinical research on developing alternative anticancer therapies.

Experimental Study of Water and CO2 Flooding in the Tight Main Pay Zone and Vuggy Residual Oil Zone of a Carbonate Reservoir

Abstract: In this paper, water and CO2 flooding processes in the upper tight main pay zone (MPZ) and lower vuggy residual oil zone (ROZ) of a carbonate light oil reservoir were experimentally studied and compared. First, some carbonate reservoir rock samples from these two zones in the Steelman oilfield (Canada) were characterized using thin-section analysis and X-ray diffraction. Second, the minimum miscibility pressure (MMP) between the light crude oil and CO2 at the actual reservoir temperature was determined. Third, a total of eight coreflood tests were conducted with the tight dolomite or vuggy limestone core plugs to examine the effects of the production pressure, CO2 injection timing, and rock properties on the water- and CO2-based oil recovery processes in the two different zones. It was found that, for the CO2 secondary flooding in the non-waterflooded tight core plugs (i.e., the MPZ), the oil recovery factor (RF) was not dramatically reduced when the production pressure was lower than the MMP. For the CO2...
