SpiroKit 3

Constrained Amino Acids

SpiroKit 3 is a smart selection of 50 smart constrained amino acids which are fundamental building blocks of modern chemistry. The combination of readily functionalized amine and carboxylic groups attached to a chiral center along with a conformationally restricted side chain provides unique three-dimensional structures with high degree of functionality.

SpiroKit 3: Constrained Amino Acids

Why SpiroKit 3?

The side chain topography of amino acids represents a crucial structural feature in drug design and constraining the side chain dihedral angles limits conformational flexibility. This makes constrained amino acids highly diverse elements for SAR campaigns, integral components of peptidomimetic drugs and invaluable motifs to improve potency, selectivity and ADME properties.
