Background: Malaria is a major disease of developing countries and the main issue in its control of resistance against all available antimalarial drugs. Our aim is to find affordable therapy for this worldwide problem. The present study was conducted to evaluate the antiplasmodial and cytotoxic activities of Euphorbia hirta and Euphorbia thymifolia. Methods: The antiplasmodial activity was evaluated against chloroquine-sensitive (MRC-2) and chloroquine-resistant (RKL-9) strain of Plasmodium falciparum by schizont maturation inhibition and Plasmodium lactate dehydrogenase (PfLDH) activity assays. The cytotoxicity was performed by MTT assay on Huh7 liver carcinoma cell line. Results: IC50 for PfLDH activity of E. hirta and E. thymifolia methanol extract against P. faciparum MRC-2 strain was 9.6 and 12.6 µg/mL, respectively and against P. faciparum RKL-9 strain was 10.2 and 11.56 µg/mL, respectively. Methanol extract of E. thymifolia showed lower IC50 (19.3 µg/mL) than methanol extract of E. hirta (24.7 µg/mL) in MTT assay against Huh7 cell line. Conclusion: Both the plant methanol extracts showed a two-fold lower cytotoxic activity against hepatocyte derived carcinoma cell line (Huh7) compared to in vitro inhibitory activity against P. falciparum strains (MRC-2 and RKL-9).

Background: Bromelain enhances anticancer impacts to chemotherapeutic agents. The question as to whether bromelain does promote in-vitro cytotoxic and proapoptotic effects of cisplatin on human prostatic carcinoma PC3 cell line was investigated. Materials and Methods: PC3 (human prostatic carcinoma) cells were treated either single or in combination with bromelain and/or cisplatin. MTT, clonogenic assay, flow cytometry and real-time quantitative polymerase chain reaction were used to investigate cell viability, colony formation, proapoptotic potential and p53 gene expression, respectively. Results: Cisplatin (IC10) combined with bromelain (IC40) significantly affected PC3 cell viability, inhibited colony formation, as well increased p53 proapoptotic gene expression compared to cisplatin single treatment. Nevertheless, bromelain-cisplatin chemoherbal combination did not display any additive proapoptotic effect compared to single treatments. Conclusion: Bromelain-cisplatin chemoherbal combination demonstrated synergistic in-vitro anticancer effect on human prostatic carcinoma cell line, PC3, that drastically reduced required cisplatin dose.

The core-shell method is used as a novel synthetic process of micronized Ti-Zeolite Na-A which involves calcination at 700°C of coated Egyptian Kaolin with titanium tetrachloride in acidic medium as the first step. The produced Ti-coated metakaolinite is subjected to microwave irradiation at low temperature of 80°C for 2 h. The prepared micronized Ti-containing Zeolites-A (Ti-Z-A) is characterized by FTIR, XRF, XRD, SEM, and EDS elemental analysis. Ag-exchanged form of Ti-Z-Ag is also prepared and characterized. The Wt% of silver exchanged onto the Ti-Zeolite structure was determined by atomic absorption spectra. Thein vitrocytotoxic activity of Ti-Z-Ag against human hepatocellular carcinoma cell line (HePG2), colon cell line carcinoma (HCT116), lung carcinoma cell line (A549), and human Caucasian breast adenocarcinoma (MCF7) is reported. The results were promising and revealed that the exchanged Ag form of micronized Ti-Zeolite-A can be used as novel antitumor drug.
