N-Acetylmuramyl-L-Ala-D-Glu-NH2 (muramyl dipeptide) and several of its derivatives are effective immunoactivators that can enhance nonspecific resistance to infection but can also elicit fever. In contrast, one of its stereoisomers, N-acetylmuramyl-D-Ala-D-Glu-NH2, is devoid of both these activities. Our present report demonstrates

As a new application of a thermogel, a poly(ethylene glycol)-b-poly(L-alanine) (PEG-L-PA) gel encapsulating fibroblasts was investigated for wound healing. The fibroblasts were encapsulated by the temperature sensitive sol-to-gel transition of the polymer aqueous solution. Under the in vitro three-dimensional (3D)

The amide I mode is a highly structure sensitive vibration of polypeptides that gives rise to a very strong band in IR absorption and a moderate band in Raman spectra. Many theoretical simulations of IR-band profiles have been undertaken thus

We compare the energetic and structural properties of fully optimized α-helical and antiparallel β-sheet polyalanines and the energetic differences between axial and equatorial conformations of three cyclohexane derivatives (methyl, fluoro, and chloro) as calculated using several functionals designed to treat

A new two-state polymer folding model is proposed, in which the folding of a stiff helical polymer is enabled by allowing for short sequences of coils connecting shorter and separated helices. The folding is driven by short-range attraction energy among
