Growth inhibition and mechanism of action of p-dodecylaminophenol against refractory human pancreatic cancer and cholangiocarcinoma

Pancreatic Cancer and cholangiocarcinoma are aggressive and drug-resistant refractory cancers. Based on N-(4-hydroxyphenyl)retinamide (3), a synthetic amide of all-trans-retinoic acid (RA), p-dodecylaminophenol (1) was developed to be an effective Anticancer agent without key side-effects of these agents. Compound 1 suppresses cell growth of pancreatic Cancer (MIA Paca2) and cholangiocarcinoma (HuCCT1), potentially by inhibiting Ras expression and signaling through ERK pathways in MIA Paca2 cells and both ERK and Akt pathways in HuCCT1 cells. Compound 1 inhibits proliferation of these cells to a greater extent than either RA or 3. Compound 1 may represent a potent and useful anti-cancer drug for use against pancreatic Cancer and cholangiocarcinoma that lacks their key side-effects.
