Proton nmr parameters are reported for DMSO-d6 solutions of two receptor-selective substance P analogues: Ac[Arg6, Pro9]SP6-11, which is selective for the NK-1 (SP-P) receptor and [pGlu6, N-MePhe8]SP6-11, which selectively activates the NK-3 (SP-N) receptor. Full peak assignments...

We have successfully investigated here, using a variety of NMR probes, the nature of the DMSO-denatured state of DLC8. The detailed analysis of structural preferences in the denatured state indicates that the protein exhibits native helical preferences in the segment of the polypeptide chain that ...
marginal peak could not be found in aqueous solution containing DMSO.In addition,with increasing amount of protein,T m (II)shifted toward lower temperature,and ΔH m (II)decreased along with the temperature gap between two transitions lengthened.The results were considered to be due to the ...
The structures of the polymers 3 were supported by H-1 NMR, B-11 NMR, and IR spectra. The obtained polymers were soluble in common organic solvents such as tetrahydrofuran, chloroform, and benzene. The peak due to the pi-pi* transition of 3a was observed at 415 nm, which was ...

Considering the CDF of DMSO and water (cf. Fig.7), a similar good agreement of the overall pattern can be obtained between the results of the AIMD and FFMD simulations. The first peak (30 – 240 pm, 145 – 180^{\circ }) shows the hydrogen bond between DMSO and water. The second ...
