Peptide therapeutics would seem to occupy a sweet spot between small molecules and biologics. Small molecules, which represent the majority of clinical drugs, preferentially bind hydrophobic pockets or cavities, [...]
Circle Pharma Inc. said its first collaboration with Pfizer Inc. has led to the identification of a series of bioavailable macrocyclic peptides capable of acting as potent and cell-permeable modulators of CXCR7. [...]
Results from its collaborative work with Pfizer to develop a potent and orally bioavailable macrocycle modulator have been published [...]
David Spellmeyer, PhD, has been appointed as Circle Pharma's chief scientific officer [...]
Cyclic peptide natural products and their synthetic mimics have gained prominence as potential sources of next‐generation therapeutics and biological probes. The size and structural complexity of these compounds sets them apart from common synthetic drugs.

Macrocyclic peptides are considered large enough to inhibit “undruggable” targets, but the design of passively cell-permeable molecules in this space remains a challenge due to the poorly understood role of molecular size on passive membrane permeability.
