a new series of alkylthio imidazole analogues of captopril, an ace inhibitor used in the treatment of hypertension, was designed and synthesized in order to obtain agents more active than captopril with less side effects. all the compounds thus prepared were purified and characterized by ir, nmr and mass analytical instruments.

objective: alpha-synuclein is a major component of protein plaques in synucleinopathies, particularly parkinson’s disease. the purpose of this study is to assess the inhibitory effects of cuminaldehyde on the fibrillation of alpha-synuclein. methods: alpha-synuclein was expressed in escherichia coli and subsequently purified. for the process of fibrillation, purified protein was incubated at 3...

factors such as oxidative stress and reduced acetylcholine level have been implicated in alzheimer’s disease (ad) pathology and recently there has been a trend towards natural product research to find potential sources of antioxidants and acetylcholinesterase inhibitors in the plants kingdom. centaurea is a genus with about 500 species world wild, many of them have shown to possess biologic act...

In this study, thyme essensial oil was extracted by water distillation method and was analysed by GS/MS, then we investigated the antifungal effect of this essential oil on Fusarium oxysporum f.sp. ciceri. (A), Macrophomina phaseolina (B), Bipolaris spicifera (C) on the basis of agar dilution method with different concentrations (200, 400, 800 and 1600) The test was carried out with factorial e...

inhibitor development is a lifelong challenge for patients with bleeding disorders who received replacement therapy. most commonly, inhibitor formation was observed in hemophilia a patients but patients with rare bleeding disorders (rbd) especially patients with deficiency of factor xiii (fxiii) and factor v (fv) can develop an inhibitor against exogenous factors. several factors considered as ...

results the minimal inhibitory concentration (mics) values of myrtus communis leaves extract ranged 0.625-5.0 µg/µl and 5-40 µg/µl against tested candida spp. and aspergillus spp., respectively. conclusions results revealed that the ethanolic extract of myrtus communis leaves have antifungal potency against both pathogenic tested fungi, and it can be used as a natural antifungal agent. material...

OBJECTIVE Somatic mutations in the epidermal growth factor receptor gene are associated with a therapeutic response to epidermal growth factor receptor tyrosine kinase inhibitors such as gefitinib and erlotinib in patients with non-small cell lung cancer. Although the safety profile of these drugs is favorable, a small proportion of patients with EGFR mutation-positive non-small cell lung cance...

background: leukemia inhibitor factor (lif) is a very important pleiotropic cytokine which belongs to interleukin-6 (il-6) family. lif exerts multiple effects on different types of cells and tissues with numerous regulatory effects in vivo and in vitro. it is a lymphoid factor, which performs a number of activities including cholinergic neuron differentia­tion, control of stem cell pluripotency...

copper amine oxidases (caos) catalyse the oxidative de-amination of biogenic amines which are ubiquitous compounds essential for cell growth and proliferation. the enzymes are homodimers containing both topaquinone and a cu(ii) ions as cofactors at the active site of each subunit. after extraction and purification of chickpea (cicer arietinum) amine oxidase by chromatoghraphy, km and vmax of th...

Angiogenesis and tumor growth were inhibited in two different animal models by regional infusion of a partially purified cartilage extract. In rabbits bearing corneal implants of V2 carcinoma and receiving the inhibitor, vascular growth rates were < 3% of those in control animals receiving either Ringer's solution or bovine trypsin inhibitor (Trasylol). Subconjunctival B16 melanoma implants in ...
