CycPeptMPDB: A database aimed at promoting drug design using cyclic peptides

The Pharma Data

One of the greatest challenges in modern drug design is to find compounds that satisfy somewhat contradictory requirements – they need to be small enough to permeate human cell membranes, while being large enough to target various protein surfaces and proteinprotein interactions.

Cell-penetrating peptides as a delivery system for oligonucleotides

Drug Discovery World

Oligonucleotides act on the RNA level through different molecular pathways, but there is a major drawback when using them as drugs: their poor bioavailability and cellular uptake. These peptides typically contain up to 30 amino acids and can be cationic, amphipathic or both. These considerations limit their application as therapeutics.
