AbstractTwo undescribed Tricholoma triterpenoids, namely tricholopardins C (1) and D (2), were isolated from the wild mushroom Tricholoma pardinum. Their structures with absolute configurations were elucidated by spectroscopic methods, as well as the single crystal X-ray diffraction. Compounds 1 and 2 were further obtained by chemical conversions from the known analogues. Compound 1 showed significant cytotoxicity to MCF-7 and Hela cell lines with IC50 values of 4.7 μM and 9.7 μM, respectively. Its mechanism of inducing MCF-7 cell apoptosis was studied briefly.

Abstract In this investigation three ancient Egyptian medical plants; Plantago albicans L., Thymelaea hirsuta (L.) Endl. and Urginea maritima (L.) were chosen to explore their biochemical properties, anticancer and antimycotic activities against clinical dermatophytes. Growing of Trichophyton soudanense, Trichophyton erinacei, Microsporum audouinii, Microsporum gypseum, Microsporum gallinae, Microsporum ferrogenium, Microsporum cookie, Microsporum racemosum, Microsporum persicolor and Microsporum canis were totally inhibited by the 100 µg/mL of P. albicans methanolic extract. Whereas the growth of T. soudanense, T. erinacei, Trichophyton rubrum, Trichophyton tonsurance and Trichophyton mentagrophytes and Epidermophyton floccosum were 100% inhibited by the methanolic extract of T. hirsiuta at 100 µg/mL concentration, however its acetone extract was more active against Microsporum species. The highest fungi toxicity against all dermatophytic fungi was detected in both methanol and acetone extract of U. maritima at a concentration ranged between 50 to 100 µg/mL. Methanolic extract of P. albicans inhibited the viability of HCT-116, HepG-2, MCF-7 and HeLa cell lines by (41%, 40%, 80% and 81%); (30%, 20%, 66% and 70%); (19%, 0%, 49% and 57%); (5%, 0%, 35% and 45%) and (0%, 0%, 21% and 40%) at 25, 50, 100, 200 and 300 µg/mL, respectively. Moreover, the cells death after treatment with the same concentrations of T. hirsuta methanol extract were (10%, 20%, 23% and 60%); (16%, 40%, 58% and 80%); (40%, 50%, 80% and 100%); (51%, 65%, 100% and 100%) and (49%, 82%, 100% and 100%) in HCT-116, HepG-2, MCF-7 and HeLa cells, respectively. Viability of HCT-116, MCF-7 and HepG-2 cell lines was totally suppressed with 100 µg/mL whereas the HeLa cell growth was reduced to 10% and totally killed at 100 and 200 µg/mL, respectively of U. maritima methanolic extract. All data approve the significance of Egyptian ethnomedical plants as potent source of diverse bioactive pharmaceutical metabolites.

AbstractIn the current work, iron oxide magnetic nanoparticles (MNP’s) were synthesized by thermal decomposition of Fe(acac)3-(iron acetylacetonate) compounds in high-boiling organic solvents containing stabilizing surfactants and examined as possible agents for magnetic hyperthermia treatment, according to their structural, magnetic and heating properties. Three different cancer cell lines (DA3, MCF-7 and HeLa cell lines) were used to assess the suitability of the MNP’s. The experimental results proved that the synthesized MNPs are non-toxic and the uptake efficiency was extremely good. Further, from in vitro hyperthermia results, very fast thermal response was observed (reaching hyperthermia levels in less than 200 s), which minimize the duration of the cell and human body exposure in a high frequency AC external magnetic field.
