The anticancer drug candidate 1,3-dibenzyl-4,5-diphenyl-imidazol-2-ylidene gold(I) chloride (NHC-AuCl) and its 2',3',4',6'-tetra-O-acetyl-β-D-glucopyranosyl-1’-thiolate derivative (NHC-AuSR), which is a potential ligand for glucose transporters, were tested on the NCI 60 cancer cell panel in vitro. NHC-AuCl and NHC-AuSR showed very good activity against a wide range of human cancer cell lines inclusive renal cell cancer wit Read More

Urogenital schistosomiasis is a chronic infection caused by the human blood fluke Schistosoma haematobium. Schistosomiasis haematobium is a known risk factor for cancer leading to squamous cell carcinoma of the urinary bladder (SCC). This is a neglected tropical disease endemic in many countries of Africa and the Middle East. Schistosome eggs produce catechol-estrogens. These molecules are metabolized to active quino Read More

A series of novel dimethyl ((aryl/heteroarylamino) (4-(pyrrolidin-1-yl) phenyl)) methyl phosphonates were synthesized by simple and an efficient one-pot three component Kabachnik- Fields reaction. Pyrrolidino-4-benzaldehyde (1), different substituted amines 2a-l and dimethylphosphite (3) were reacted at room temperature using aqueous zinc tetrafluoroborate as catalyst under solvent free conditions to obtain the title com Read More

In this in vitro study, a series of amino-pyrazole derivatives were designed, synthesized, and evaluated against five human cancer cell lines (PC3, A549, HL60, HCT116, and SW620) for their anti-proliferative effects and inhibition of p53-MDM2 binding. The results of the biological evaluation showed that this series of compounds has improved inhibition of p53-MDM2 binding and anti-proliferative activities compared to previou Read More

Some 1(2H)-phthalazinone derivatives were synthesized and their chemical structures were confirmed by 1H-NMR, 13C-NMR, mass and elemental analysis. Subsequently, modified Ellman’s method was used to determine both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitory activities of the synthesized compounds. The activity results showed that compound 8c was the most active AChE inhibitor wit Read More

In the present study, a series of new 6-benzamide containing 4-phenylquinazoline derivatives were designed and synthesized as PI3Kδ inhibitors. The preliminary SAR for this series of compounds was established. PI3Kδ inhibitory assay showed that most of the synthesized compounds achieved significant activity against PI3Kδ. Compound 12h was the most potent PI3Kδ inhibitor, displaying an IC50 value of 17 nM. These results r Read More

CD38 is regarded as a potential target. Inhibitors against CD38 can regulate calcium metabolism in human body to impede the occurrence of disease, including diabetes and myeloma. In this work, 47 thiazoloquin(az)olin(on)es analogues with high pIC50 values in the micromolar ranges are studied by three-dimensional quantitative structure-activity relationship (3D-QSAR) and molecular docking. The comparative molecule fi Read More

A new series of 3-aryl/heteroaryl-5-benzofurnyl pyrazoles [5(a-l)] were synthesized from 1,3-β-monothiodiketones through the cyclocondensation reaction with phenyl hydrazine in good yield and characterized by IR, 1H and 13C NMR, Mass and elemental analyses. All compounds were subjected to evaluate antimicrobial activity against various bacteria viz Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtili Read More

Some novel pyrazole derivatives were designed and synthesized through multi-step reactions from substituted phenol as starting material. Their structures were confirmed by 1H NMR, FTIR, MS and elemental analysis. All these compounds were evaluated their herbicidal activity. The preliminary bioassay results indicated that some of title compounds displayed moderate herbicidal activity at 200 μg/mL. Among them, Read More

Various benzimidazole compounds containing a triazole nucleus were synthesized and screened for their antioxidant activies. The structures of newly synthesized compounds were characterized by 1H NMR, 13C NMR and elemental analysis data. Antioxidant features of the synthesized compounds were investigated by different processes such as 2,2-diphenyl picryl hydrazyl (DPPH),2,2'-azino-bis(3-ethylbenzothiazoline-6- Read More

N-acetylcysteine (NAC) exhibits diverse pharmacological effects due to the free radical scavenging ability of the reduced thiol. Extensive deacetylation in liver, high protein binding and poor permeability results in low bioavailability of NAC. These setbacks are also the contributing factors in failure to confirm the benefits of NAC in prevention of diseases involving oxidative stress. Present study was aimed at improvin Read More

A series of new biologically potent N-substitutedpyrazoline derivatives have been synthesized by reacting hydrazine hydrate and its derivatives with (2)-1-(4-chlorophenyl)-3-[4-(propan-2- yl)phenyl]prop-2-en-1-one, which in turn prepared by the base catalysed Claisen-Schmidt condensation reaction of 4-(propan-2-yl)benzaldehyde and 4-chloroacetophenone. All the synthesized compounds, 2a-e, 3a-d, 4a,b and 5a-c were scr Read More

Aryloxy phenoxy propionic acid esters (APP) chiral herbicide is a kind of acetyl coenzyme A carboxylase enzyme (Acetyl CoA Carboxylase) inhibitor. Sulfonylureas and diphenylethers herbicide are the acetohydroxyacid synthase (ALS) inhibitors and 4,6-dimethoxypyrimidine is the major active group. Bioisosterism and active group combination principle were the primary and effective ways to develop novel pesticides. By using t Read More

The benzyloxy-benzyl moiety is a valuable building block in medicinal chemistry, e.g. in case of the voltage gated sodium channel blockers Safinamide and Ralfinamide. To prepare further derivatives a series of (iodobenzyl)oxybenzaldehydes (3a-3i) useful intermediates for the synthesis of biologically active compounds were synthesized in high yields by O-benzylation of 2-, 3- and 4- hydroxybenzaldehydes (2a-2c) with a v Read More

Inflammation and its treatment has been studied for thousands of years and is characterized as a nonspecific but beneficial response of tissues to injury. Inflammation is distinguished by symptoms such as redness, pain, and swelling. The anti-inflammatory agents are used to encounter inflammation. It has been found that conventional synthetic nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in various infla Read More
