Activating Compound

Activating Compound Comment Organism Structure
additional information the androgen R1881 induces the enzyme about 4.5fold in androgen receptor AR-positive prostate cell lines 22Rv1 and LNCaP, but not in the AR-negative PC-3, HK-293, or HeLa cells, androgen up-regulation of NAT1 is prevented by the AR antagonist flutamide, the effect of R1881 may not be by direct transcriptional activation of NAT1, overview Homo sapiens
R1881 the androgen R1881 induces NAT1 activity in androgen receptor-positive prostate cancer cells Homo sapiens

additional information
-
it is shown that NAT1 activity is induced by synthetic androgen R1881 in androgen receptor (AR)-positive prostate lines 22Rv1 and LNCaP, but not in the AR-negative PC-3, HK-293, or HeLa cells. The effect of R1881 is dose dependent, with an EC50 for R1881 of 1.6 nmol/L Homo sapiens
