Simulating the mechanism of antimicrobial lipopeptides with all-atom molecular dynamics.
The emergence of antibiotic resistant pathogens is one of the major medical concerns of the 21st century, prompting renewed interest in the development of novel antimicrobial compounds. Here we use microsecond-scale all-atom molecular dynamics simulations to characterize the structure, dynamics, and membrane-binding mechanism of a synthetic antimicrobial lipopeptide, C16-KGGK. Our simulations s...
متن کاملMolecular Mechanisms of Antimicrobial Resistance
In the last 50 years bacteria have demonstrated a remarkable ability to develop and share resistance to every antibiotic that has been developed, often by quite unexpected mechanisms and much more readily than was originally predicted (Spratt, 1994). Antibiotic resistant bacteria can live and multiply in the presence of therapeutic levels of antibiotics. They can be resistant in their natural s...
متن کاملShort alkylated peptoid mimics of antimicrobial lipopeptides.
We report the creation of alkylated poly-N-substituted glycine (peptoid) mimics of antimicrobial lipopeptides with alkyl tails ranging from 5 to 13 carbons. In several cases, alkylation significantly improved the selectivity of the peptoids with no loss in antimicrobial potency. Using this technique, we synthesized an antimicrobial peptoid only 5 monomers in length with selective, broad-spectru...

نظریه هوش چندگانه قسمتهای متفاوت هوش بشری را مورد بررسی قرار می دهد که با شناخت آن شخص به درک بهتری از توانایی های خود میرسد و در نتیجه سعی در استفاده از آن جهت یادگیری بهتر میکند. همچنین با شناخت استعداد دانش آموزان، فرایند یادگیری بهتر میشود. هدف از انجام دادن این تحقیق بررسی رابطه بین هوش ریاضی و استعداد یادگیری زبان انگلیسی میباشد. برای انجام این تحقیق از پرسشنامه هوش ریاضی که توسط شیرر در ...
Exploring the Interaction Mechanism of Coumarin with Bovine β-Casein: Spectrofluorometric and Molecular Modeling Studies
This paper is designed to examine the binding behavior of Coumarin with bovine -casein (βCN) through fluorescence spectroscopy and molecular modeling techniques. The data analysis on fluorescence titration experiments at various temperatures represents the enthalpy driven nature for the formation of Coumarin–βCN complex and the prevailed role of hydrogen bonds and van der Waals interactions in...
