Biochem/physiol Actions

AP20187 is a synthetic and cell-permeable FK506 (tacrolimus) analog that acts as a chemical dimerizer, a chemical inducer of dimerization (CID), to reversibly dimerize and activate fusion proteins containing a growth factor receptor signaling DmrB domain. It has been used to induce oligomerization of cell surface receptor proteins and to study the activity and/or re-localization of any protein that affected by oligomerization. AP20187 has been found to act as a senolytic. In a transgenic mouse model that expresses the FK506-binding protein–caspase 8 (FKBP–Casp8) fusion protein, AP20187 activated FKBP-fused Casp8 in senescent cells resulting in apoptosis of the cells resulting in delayed tumorigenesis , diminished age-related organ deterioration, and extended life span.

AP20187是合成的且细胞可渗透的FK506(他克莫司)类似物,充当化学二聚体,二聚化(CID)的化学诱导剂,可逆地二聚化并激活包含生长因子受体信号转导DmrB结构域的融合蛋白。 它已被用来诱导细胞表面受体蛋白质的寡聚化,并研究任何受寡聚化影响的蛋白质的活性和/或重新定位。 已发现AP20187可以起到缓和作用。 在表达FK506结合蛋白-caspase 8(FKBP–Casp8)融合蛋白的转基因小鼠模型中,AP20187激活衰老细胞中FKBP融合的Casp8,导致细胞凋亡,导致肿瘤发生延迟,与年龄相关的器官退化减少, 并延长了使用寿命。


AP20187 (B/B Homodimerizer) is a cell-permeable ligand used to dimerize FK506-binding protein (FKBP) fusion proteins and initiate biological signaling cascades and gene expression or disrupt protein-protein interactions.

IC50 & Target

FKBP homodimerizer[1]

In Vitro

When LNCaP cells are treated with AP20187 (B/B Homodimerizer) (100 nM), ro-iCaspase-9 levels are significantly reduced, and the smaller processed active caspase-9 becomes apparent[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Real-time PCR analysis shows that AP20187 (B/B Homodimerizer) (0.5 mg/kg, 2 mg/kg, or 5 mg/kg) treatment significantly increases the levels of CHOP mRNA in the CNS of PLP/Fv2E-PERK mice at PID12. AP20187 treatment significantly alleviates EAE-induced myelin damage in these mice. AP20187 (B/B Homodimerizer) treatment significantly reduces the number of degenerating axons and increases the density of axons in the demyelinating lesions in the lumbar spinal cord of PLP/Fv2E-PERK mice[2].
