  Regioselective synthesis of polycyclic aza-oxa and aza-oxa-thia heteroarenes as Colo-205 and HepG2 carcinoma cells growth inhibitors

  摘要：

  An efficient regioselective synthesis of polycyclic diheteroaryl[b,d]pyrans and diheteroaryl[c,e][1,2]diazepines has been reported through ring transformation reactions of 2-oxo-2,5-dihydrothiochromeno [4,3-b]pyrans (3,4), 2-oxo-5,6-dihydro-2H-benzo[b]pyrano[2,3-d]oxepine/thiepine (8, 9) and 6-oxo-3,6-dihydro-2H-naphtho[1,2-b]pyrano[2,3-d]oxepine (15) by hydrazine, at ambient and reflux temperature. Nine compounds viz 5a,b; 10a,c,d; 12b; 13b; 16 and 1-methylthio-5,6-dihydrobenzo[f]quinoline (0.1-100 mu M) were screened for their cytotoxicity in normal (IEC-6), carcinoma (Colo-205) and HepG2 cell lines. None of the compounds showed cytotoxicity in normal IEC-6 cells while 10a,d and 16 resulted in killing of Colo-205 cells with IC50 ranging 20-60 mu M while 10c and 13b caused killing of HepG2 cells with IC50 values ranging 60-80 mu M concentration. Further, 10a,d and 16 caused apoptosis through a cascade of mitochondrial pathway in Colo-205 cells indicating anticancerous potential against intestinal cancer. Interestingly, compounds 10c and 13b exhibited apoptosis through mitochondrial pathway in HepG2 cells suggesting anticancer activity against hepatic cancer. (C) 2014 Elsevier Masson SAS.
