Constrained N-Fmoc amino acids
SpiroKit 8: Constrained N-Fmoc amino acids

Why SpiroKit 8?

Amino acid side chain topography is a crucial structural feature in drug design and constraining the side chain dihedral angles limits conformational flexibility. Constrained N-Fmoc amino acids are therefore of great interest for SAR campaigns of peptidomimetic drugs, design of novel macrocycles and novelty introduction in DEL collections.
