摘要:
The present invention provides spreading agents based on sequence-specific oligomers comprising a peptoid, a peptide-peptoid chimera, a retropeptoid or a retro(peptoid-peptide) chimera, and methods for using the same, including for the treatment of respiratory distress of the lungs. The spreading agents are sequence-specific oligomers, including retrosequence-specific oligomers, based on a peptide backbone, that are designed as analogs of surfactant protein-B or surfactant protein-C.

Synthesis of an anlogue of the (5-14) decapeptide of equine angiotensinogen partially retro-inverted at the Phe-Val bond, of formula: The retro-inverso analogue inhibits renin with high resistance to enzymatic degradation, and can be used in the treatment of renin-dependent hypertension.
摘要:
The present invention relates to novel pentapeptide of formula
pAad-Glu-Asp-Ser-Gly-OH,
wherein pAad represents the acyl group of pyro-alpha-aminoadipic acid, and salts thereof having specific inhibiting effect on epidermal cell proliferation, and pharmaceutical compositions comprising the same. The invention also relates to a process for the preparation of both the pentapeptide and the pharmaceutical composition.
