| Bioactivity | PD1-PDL1-IN 1 (compound 16) is a potent programmed cell death 1 (PD-1) inhibitor. PD1-PDL1-IN 1 is useful as immune modulator[1]. | 
| Invitro | PD-1 (or Programmed Cell Death 1 or PDCD1) is a ~55kD type I membrane glycoprotein and is a receptor of the CD28 superfamily that negatively regulates T cell antigen receptor signalling by interacting with the specific ligands. PD-1 is suggested to play significant role in the maintenance of self-tolerance[1]. |
