nbo analysis and density functional theory (dft: b3lyp/6-311+g**) based method were used to study the impacts of the anomeric effects (ae) on the conformational properties of 2-methoxy-1,2,4,5-tetrahydro-benzo[d]oxepine (1), -thiepine (2) and -selenepine (3). the gibbs free energy difference (geq–gax) values (i.e. δgeq-ax) at 298.15 k and 1 atm between the axial and equatorial conformations inc...
Bacterial α-2-macroglobulins have been suggested to function in defence as broad-spectrum inhibitors of host proteases that breach the outer membrane. Here, the X-ray structure of protease-cleaved Escherichia coli α-2-macroglobulin is described, which reveals a putative mechanism of activation and conformational change essential for protease inhibition. In this competitive mechanism, protease c...
COURSE INFORMATION The following text is a summary of a two-hour lecture sequence presented in the course, Advanced Medicinal Chemistry I. This course is required for all MS and PhD students in Duquesne University’s Medicinal Chemistry Graduate Program. It is also available as an elective for undergraduate students in their last semester of didactic work. The course emphasizes the basic chemica...
