In the near future, design of a new generation of drugs targeting proteins will be required. Considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. So far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. In these studies, use of spectroscopic method...

In depth interaction studies between calf thymus deoxyribonucleic acid (CT-DNA) and a series of four structurally relative palladium(II) complexes [Pd(en)(HB)](NO3)2 (a-d), where en is ethylenediamine and heterocyclic base (HB) is 2,2'-bipyridine (bpy, a); 1,10-phenanthroline (phen, b); dipyridoquinoxaline (dpq, c) and dipyridophenazine (dppz, d) (Figure 1), were performed. These studies have b...

Objective: Shortia and other members of the Diapensiaceae family have ethnomedicinal history in both Eastern and Western hemispheres. Based on ethnopharmacological and chemosystematic evidence, pharmacological and toxicological bioassays were conducted on the rare plant Oconee Bell, Shortia galacifolia. Materials and Methods: Extracts were examined in assays for antimutagenicity, antitumor and ...

PEPPSI type Pd complexes have wide applications in recent years. Serum albumin carries very important molecules such as oleic and linoleic acids, nitric oxide, vitamin B6, thyroid so do many drugs. In this study, a novel NHC molecule its Pd-PEPPSI complex were synthesized characterized. Both the ligand optimized by DFT-based calculation methods. The binding properties of with HSA analyzed molec...

Background:Epidermal growth factor receptor (EGFR) overexpression is a characteristic of several malignancies and could be considered as an excellent target for designing specific inhibitors such as anti-EGFR monoclonal antibodies for cancer therapy. Drawbacks exerted by large sizes of full-length antibodies have lead to the development of single chain antibodies, which benefit from having smal...

Human MMP-26 (matrix metalloproteinase-26) (also known as endometase or matrilysin-2) is a putative biomarker for human carcinomas of breast, prostate and other cancers of epithelial origin. Calcium modulates protein structure and function and may act as a molecular signal or switch in cells. The relationship between MMPs and calcium has barely been studied and is absent for MMP-26. We have inv...

The ability of lactoferrin (Lf), an iron-binding glycoprotein that is also called lactotransferrin, to bind lipopolysaccharide (LPS) may be relevant to some of its biological properties. A knowledge of the LPS-binding site on Lf may help to explain the mechanism of its involvement in host defence. Our report reveals the presence of two Escherichia coli 055B5 LPS-binding sites on human Lf (hLf):...

The synthesis of four tetra-tacrine clusters where the tacrine binding units are attached to a central scaffold via linkers variable lengths is described. multivalent inhibition potencies for were investigated acetylcholinesterase. Two displayed small but significant potency in which affinity each increased up 3.2 times when they connected scaffold.
