Nitrogen-containing bisphosphonates (N-BPs) are important drugs widely used in a variety of bone resorption diseases. These compounds target the farnesyl pyrophosphate synthase (FPPS), a key enzyme of the mevalonate pathway involved in several pathologies. The inhibition of FPPS is a promising pharmacological approach and the development of structure-based methods for the prediction of the enzyme-inhibitor bindin Read More

In this work, three different groups of drugs such as 12 analgesic drugs, 11 cardiovascular system drugs and 36 “other” compounds, respectively, were analyzed with cluster analysis (CA), principal component analysis (PCA) and factor analysis (FA) methods. All chemometric analysis were based on the chromatographic parameters (logk and logkw) determined by means of high-performance liquid chromatography (HPLC) Read More

A new series of (E)-N,2,3-triarylacrylamide derivatives were designed and synthesized as potent anticancer agents. Cytotoxicity of the 26 target compounds was evaluated in vitro against six cancer cell lines (HCT116, A549, MDA-MB-468, HepG2, SKNMC and SK-OV-3) by Sulforhodamine B colorimetric assay. The most promising compound, 4h, was as potent as the reference drug cisplatin (DDP). Preliminary structure–activit Read More

2,4-Disubstituted thiophene derivatives were synthesized and assessed for antiinflammatory and anti-cancer activities by targeting two important enzymes of the arachidonic acid metabolism. Both lipoxygenase and cyclooxygenase enzymes play vital role in chronic inflammation and carcinogenesis. Previous studies have proved that COX-2 and 5-LOX are highly activated in various types of cancers; hence inhibition of t Read More

Azolium (imidazolium and benzimidazolium) salts are known as stable precursors for the synthesis of Metal-N-Heterocyclic Carbene (M-NHC) complexes. Recently, some reports have been compiled indicating that benzimidazolium salts have anticarcinogenic properties. The current research is the further investigation of this phenomenon. Three ortho-xylene linked bis-benzimidazolium salts (1-3) with octyl, nonyl and Read More

A series of 17-phenylpropylamine/phenoxyethylamine-substituted derivatives of geldanamycin (GA) was synthesized and evaluated for the anti-proliferation activity on human cancer cell line MDA-MB-231. All the derivatives exhibited potent cytotoxicity with IC50 values range from 0.35 to 1.03 μM. Among them, 17-(2-phenoxyethylamino)-17-demethoxygeldanamycin (3) was identified as the most potent compound. Hepato Read More

Alzheimer’s disease (AD) is a type of neurodegenerative disorder which is responsible for many cognitive dysfunctions. According to the most accepted cholinergic hypothesis, cholinesterases have a major role in AD symptoms. The use of small molecules as inhibitors is one of the most useful strategies to control AD. In the present work, a series of N-phenylthiazol-2-amine derivatives was screened against acetylcholines Read More

A series of piperidyl-thienyl & 2-pyrazoline derivatives of quinolyl-thienyl chalcones were tested to observe the structural characteristics for the monoamine oxidase inhibitory (MAO) activity. In both these series, a diverse range of substituted thiophenes are used which enable the structure activity relationship. The compounds showed enhanced inhibition against MAO-A & B as compared to reference compounds. Compound Read More

In this investigation, the screening of two furanocoumarins; 5,8- dimethoxypsoralen (1) and heraclinin (2), isolated from the methanol root-extracts of Tamus communis L for their antioxidant activity and xanthine oxidase inhibitory effect was carried out, using different assays such as DPPH free radical scavenging effect, β- carotene / linoleic acid, xanthine oxidase (XO) inhibition and in addition to blood total antioxidant capacity.
