AP20187 (B/B Homodimerizer) is a novel cell-permeable and chemical inducer of dimerization, used to dimerize FK506-binding protein (FKBP) fusion proteins and initiate biological signaling cascades and gene expression or disrupt protein-protein interactions. AP20187-mediated activation of a chimeric insulin receptor results in insulin-like actions in skeletal muscle and liver of diabetic mice.

Biological Activity
| ln Vitro | AP20187 (B/B Homodimerizer) (100 nM) treatment of LNCaP cells resulted in a considerable decrease in ro-iCaspase-9 levels and a significant weakening of caspase-9 processing activity [2]. |
| ln Vivo | Real-time PCR analysis showed that AP20187 (B/B homodimer) (0.5 mg/kg, 2 mg/kg or 5 mg/kg) treatment significantly enhanced PLP/Fv2E-PERK in PID12 CHOP mRNA levels in the CNS of Fv2E. AP20187 therapy significantly decreased EAE-induced myelin damage during these procedures. AP20187 (B/B Homodimerizer) therapy dramatically reduced the number of degenerated axons and enhanced axonal density in PLP/Fv2E-PERK anatomical lumbar demyelinating lesions [2]. |

| Additional Infomation | AP20187 is a tertiary amino compound that is 2-(aminomethyl)-N,N-dimethylpropane-1,3-diamine in which the primary ammino groups have each been acylated by condensation with the carboxy group of 2-{3-[(1R)-3-(3,4-dimethoxyphenyl)-1-hydroxypropyl]phenoxy}acetic acid, the hydroxy groups of which have been esterified by condensation with the carboxy group of L-pipecolic acid, the nitrogen of which has been acylated by condensation with (2S)-2-(3,4,5-trimethoxyphenyl)butyric acid. It is a synthetic, cell-permeable ligand that can be used to induce homodimerization of fusion proteins containing the DmrB domain. It has a role as a ligand. It is a N-acylpiperidine, a carboxylic ester, an aromatic ether and a tertiary amino compound. |
