D-proline is an isomer of the naturally occurring amino acid L-Proline. D-amino acids have been found in relatively high abundance in human plasma and saliva. These amino acids may be of bacterial origin but there is also evidence that they are endogenously produced through amino acid racemase activity.

K-975 is a highly selective, orally active TEAD inhibitor, effectively inhibiting protein-protein interactions between TEAD and YAP1/TAZ.
