Dimethylcurcumin selectively enhances the degradation of androgen receptor. Dimethylcurcumin is a related compound of Curcumin (C838500). | [Biological Activity]
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]1. lu nz. et al.
