This study investigated the anticancer effect of the curcumin analog JZ534 on lung cancer cell lines H460, A549, H1975, and HCC827. The antiproliferation effect of JZ534 was measured through the methylthiazoletetrazolium assay, and cell colony formation was observed. Cell cycle and apoptosis were determined by flow cytometry, and the preliminary mechanism was studied by Western blot. Results sh...

Metformin was reported to inhibit the proliferation of many cancer cells, including melanoma cells. In this report, we investigated the effect of metformin on melanoma invasion and metastasis development. Using different in vitro approaches, we found that metformin inhibits cell invasion without affecting cell migration and independently of antiproliferation action. This inhibition is correlate...

Alkaloids are regarded as important nitrogen-containing chemical compounds that serve a rich source for discovering and developing new drugs where most plant-origin alkaloids have antiproliferation effects on different kinds of cancers. Alkaloids’ continence Calotropis procera leaves detected by two biochemical alkaloid reagents. Also GC-MS analysis leaf extract was done showed the existence on...

Abstract New system compromising of chitosan nanoparticles encapsulated pre-synthesized selenium in the presence 5-fluorouracil was successfully prepared and used for cancer antiproliferation. Selenium were synthesized using ascorbic acid as reducing agent under mild condition. Chitosan via ionic gelation technique sodium tri-polyphosphate. Characterization carried out FTIR, TEM, XRD, TGA dynam...

In the course of our continuous interest in identifying bioactive compounds from marine microbes, we have investigated a tunicate-derived fungus, Penicillium sp. CYE-87. A new compound with the 1,4-diazepane skeleton, terretrione D (2), together with the known compounds, methyl-2-([2-(1H-indol-3-yl)ethyl]carbamoyl)acetate (1), tryptamine (3), indole-3-carbaldehyde (4), 3,6-diisobutylpyrazin-2(1...

Pine, grape and witch hazel byproducts are rich sources of polyphenols. From extracts (OW) soluble in both ethyl acetate and water we have generated a collection of fractions differing in percentage of pyrogallol groups. The mixtures were highly active as free radical scavengers against DPPH. The phenolics protected red blood cells from free radical induced hemolysis and were mildly cytotoxic t...

OBJECTIVE To review the physiologic functions and clinical significance of peripheral GnRH receptors. DESIGN Literature review. All peer-reviewed journal articles published before 2010 on peripheral GnRH receptors were searched for in the Pubmed database, and relevant findings were summarized. RESULT(S) Peripheral GnRH/GnRH receptor systems may serve as regulators of hCG synthesis and impla...
