Design and synthesis of novel organometallic complexes using boronated phenylalanine derivatives as potential anticancer agents.

Drug design and discovery studies are important because of the prevalence of diseases without available medical cures. New anticancer agents are particularly urgent because of the high mortality rate associated with cancer. A series of mononuclear gold (III) and platinum (II) complexes based on boronated phenylalanine (BPA) were designed and synthesized using 4,4'-dimethyl-2,2'-dipyridyl (L1) or 1,10-phenanthroline-5,6-dion (L2) ligands to obtain promising anticancer drug candidates.

Anti-lung Cancer and Anti-angiogenic Activities of New Designed Boronated Phenylalanine Metal Complexes.

Background: Drug design and discovery studies still remain of great importance in the search for more convenient chemotherapeutic to avoid the drug resistance, systemic toxicity or the longterm side effects.

Objective: A series of mononuclear gold (III) and platinum (II) complexes based on 4-dihydroxyboryl- DL-phenylalanine (BPA) was designed and synthesized, for the first time, by using 2, 2'-dipyridyl (L1) and 4, 4'-diaminobibenzyl (L2) ligands. Characterization of the synthesized complexes was achieved by using 1H-NMR, IR, MS and elemental analyses.

Promotion of Hair Growth by Traditionally Used Delphinium Staphisagria Seeds through Inducti on of Angiogenesis.

How the seeds of Delphinium staphisagria promote hair growth in humans is yet to be discovered. This lack of information leads us to the investigation of hair promoting effects of seeds of Delphinium staphisagria in-vitro. Extract prepared from the Seed of Delphinium staphisagria (ESDS) - traditionally used for hair loss treatment - was selected and tested for the cytotoxic and angiogenic potential in endothelial cells (HUVECs) and human keratinocytes (HaCaT) cells.

Gold(III) compounds-mediated inhibition of lung cancer cell proliferation.

Research on chemotherapeutics for lung cancer is crucial for designing a new therapeutic strategy against malignant lung tumors. Although radiotherapy and chemotherapy, which are not selective for cancer cells and exert toxic effects on healthy cells, have a limited advantage, they are the primary treatment modalities for non-small lung cancer. In addition to cytotoxicity, resistance of chemotherapeutics results in failure of treatment.

Novel ferrocenyl-containing N-acetyl-2-pyrazolines inhibit in vitro angiogenesis and human lung cancer growth by interfering with F-actin stress fiber polimeryzation.

Cancer is a significant worldwide health problem generally because of lack of widespread and comprehensive early detection methods. Lung cancer is the leading cause of cancer deaths in men worldwide and the second leading cause of cancer deaths in women. To date, the available treatment regimens are not successful.

Induction of apoptosis and inhibition of cell proliferation by the cyclooxgenase enzyme blocker nimesulide in the Ishikawa endometrial cancer cell line.

Objectives: Endometrial cancer remains a leading cause of death in women and therefore the development of new therapies is essential. The present study evaluated the effects of nimesulide alone, cisplatin alone, and combination of cisplatin and nimesulide on an Ishikawa cell line with respect to cytotoxicity and induction of apoptosis in vitro.

Study Design: Ishikawa cells were treated with increasing doses of nimesulide alone, cisplatin alone, and a combination of cisplatin and nimesulide.

Assessment of anti-angiogenic and anti-tumoral potentials of Origanum onites L. essential oil.

Medicinal plants and culinary herbs with anti-angiogenic and little toxicity properties have gained importance. Non-toxic anti-angiogenic phytochemicals are useful in combating cancer by preventing the formation of new blood vessels to support the tumor growth. We have investigated the essential oil of Origanum onites L.
