摘要:
Click triazole-based ollgopeptides 1-3 were found to self-dimerize (K-dim approximate to 10-680 M-1) In a head-to-tail fashion based on H-1 variable concentration, 2D, and HID exchange NMR, VPO, CD, FT-IR studies and Gaussian 03 simulations. The dimerization constant K-dim was shown to increase with increasing number of the amino acid units. Within the same oligomeric series, the K-dim, value is strongly affected by the size of the C-terminal end group. The tripeptides 2 are also excellent organogelators of aromatic solvents.
