Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and acquired immunity. FimH adhesin, a minor component of type 1 fimbriae encoded by Uropathogenic Escherichia coli (UPEC) is a PAMP of TLR4 tha...

UV-visible and Fluorescence spectroscopic methods were employed to study the interaction of human serum albumin (HSA) with Valacyclovir Hydrochloride. Additionally, molecular dynamics and molecular docking simulations were used to visualize and specify the binding site of Valacyclovir Hydrochloride. The Stern-Volmer and van't Hoff equations along with spectroscopic observations, were used to de...

Background: The present study has been designed with the aim of evaluating A-kinase anchoring proteins 3 (AKAP3)and Procollagen-Lysine, 2-Oxoglutarate 5-Dioxygenase 3 (PLOD3) gene mutations and prediction of 3D proteinstructure for ligand binding activity in the cases of non-obstructive azoospermic male.Materials and Methods: Clinically diagnosed cases of non-obstructive azoos...

quorum sensing controls the luminescence of vibrio fischeri through the transcriptional activator luxr and the specific autoinducer signal produced by luxi. amino acid sequences of these two genes were analyzed using bioinformatics tools. luxi consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by sspro8. luxi belongs to the autoinducer synthetase fa...

recently, several studies have shown that the metal-fluoroquinolone complexes have more antibacterial and cytotoxic effects in comparison with free fluoroquinolones. these results may introduce new drugs for chemotherapy with fewer side effects. in this work a bidentated zinc (ii) complex with ofloxacin (ozc) was synthesized and cytotoxicity activities and dna binding of the resulted complex wa...

Medicinal chemistry depends on many other disciplines ranging from organic chemistry andpharmacology to computational chemistry. Typically medicinal chemists use the moststraightforward ways to prepare compounds. The validation of any design project comes from thebiological testing.Studies of the binding site of vinblastine by a single cross—linking experiment identified it asbeing between resi...
