Abstract Hyperhomocysteinemia has recently been identified as an important risk factor for Alzheimer's disease (AD). One of the potential mechanisms underlying harmful effects of homocysteine (Hcy) is site-specific acylation of proteins at lysine residues by homocysteine thiolactone (HCTL). The accumulation of amyloid β-peptide (Aβ) in the brain is a(More)
Apoptosis is a naturally occurring process by which a cell is directed to programmed cell death. Chemotherapy drugs affect the cancer cells by the apoptotic induction. During the present study, a series of 4H-chromene-3-carbonitrile was synthesized by one-pot method as the inducers of apoptosis. Cytotoxic effects of six compounds of(More)
Tau isoforms promote neuronal integrity through binding and stabilization of microtubule proteins (MTP). It has been shown that hyperphosphorylation of tau contributes to Alzheimer's disease (AD) pathology and related tauopathies. However, other pathogenic modifications of tau have not been well characterized. It is well accepted that elevated level of(More)
A series of chloro-substituted-2′-hydroxychalcones were prepared and evaluated for their cytotoxic effects against K562 and SK-N-MC human cancer cell lines and as the inhibitors of tubulin polymerization. The 3,5′-dichloro- analogue (compound 3) inhibited the assembly of protofilaments with 89% inhibition. Compound 3 was found to be bound to tubulin with a(More)
CONTEXT As microtubules are highly involved in cellular growth, it appears to be a preferential target for cancer treatment. Therefore, many efforts have been performed to discover drugs that affect on microtubule function. Several microtubule inhibitors are in various stages of laboratory evaluations and clinical trials. OBJECTIVE A series of(More)
HIV-1 integrase is an extremely important nominee in developing new and effective drugs especially naphthyridine compounds against acquired immune deficiency syndrome. The quantitative structure–activity relationship (QSAR) modeling is the most powerful method in computer-aided drug design and will be used to help the design of new naphthyridine(More)
Previous studies suggest that 4-aryl-4H-chromenes are potent apoptosis-inducing agents in various cancer cell lines. In this study, anti-proliferative and apoptotic effects of the derivatives from 4-aryl-4H-chromene family were investigated in the human leukemia K562 cells using [3-(4,5)-dimethyl-2-thiazolyl]-2,5-diphenyl-2H-tetrazolium bromide (MTT) growth(More)
A series of 3-(trimethoxyphenyl)-2(3H)-thiazole thiones 5 were designed as new heterocyclic analogs of combretastatin A-4 (CA-4). Indeed, the olefinic core structure of CA-4 has been replaced by 2(3H)-thiazole thione. The general synthetic strategy to prepare compounds 5 was based on the cyclocondensation reaction between triethylammonium(More)
Helicobacter pylori is recognized as the main cause of gastritis and gastroduodenal ulcers and classified as class 1 carcinogen pathogen. Different 1,3,4-thiadiazole derivatives bearing 5-nitroaryl moiety have been shown considerable anti- H. pylori activity. In attempt to find new and potent derivatives of described scaffold, a new series of 1-(substituted(More)
The BCR-ABL fusion gene is one of the major causes of 95% of Chronic Myeloid Leukemia (CML). While, BCR-ABL protein is currently being used as a major target to treat CML. Although, current FDA-approved drugs such as; Imatinib and Nilotinib have stupendously improved the patients 5-year's survival rates, the drug resistance has dramatically reduced their(More)
