ASC-J9, is antitumor agent. ASC-J9 suppresses castration-resistant prostate cancer growth via degradation of full-length and splice variant androgen receptors targeting both fAR- and AR3-mediated PCa growth by ASC-J9 may represent the novel therapeutic approach to suppress castration-resistant PCa. ASC-J9 ameliorates spinal and bulbar muscular atrophy phenotype via degradation of androgen receptor.
The androgen receptor (AR) is a type of nuclear receptor that is activated by binding either of the androgenic hormones, testosterone, or dihydrotestosterone in the cytoplasm and then translocating into the nucleus. [1]The binding of an androgen to the androgen receptor(AR) results into a conformational change, in turn, which causes dissociation of HSP, transport from the cytosol into the cell nucleus, and dimerization. The AR dimer binds to a specific sequence of DNA known as HRE which can interact with other proteins in the nucleus, leading to up-regulation or down-regulation of specific gene transcription.[2]
ASC-J9, the AR degradation enhancer, suppressed both macrophage migration and subsequent PCa cell invasion. Additionally, ASC-J9 can regulate pSTAT3-CCL2 signaling using two pathways: an AR-dependent pathway via inhibiting PIAS3 expression and an AR-independent pathway via direct inhibition of the STAT3 phosphorylation/activation through mouse model in vivo with orthotopically injected TRAMP-C1 cells. In conclusion,a new and better therapeutic strategies using ASC-J9 alone or a combinational therapy that simultaneously targets androgens/AR signaling and PIAS3-pSTAT3-CCL2 signaling to better battle PCa growth and metastasis at castration-resistant stage.[3]

In mice, ASC-J9 significantly decreases developing distant metastatic tumors in diaphragm and lymph nodes. There are little change in mice body weight among all the mice treated. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
