title: Synthesis and anticancer evaluation of bis(benzimidazoles), bis(benzoxazoles), and benzothiazoles.
abstract: Four classes of UK-1 analogues were synthesized and their cytotoxicity testing against human A-549, BFTC-905, RD, MES-SA, and HeLa carcinoma cell lines was determined. The results revealed that UK-1 and four of these analogues (15-18) are potent against the cancer cell lines. In particular, compound 16 is more potent than UK-1 against A-549 and HeLa cell lines, and compounds 15, 17, and 18 selectively exhibit potent cytotoxic activity against the BFTV-905 cells (IC50 9.6 microM), A-549 cells (IC50 6.6 microM), and MES-SA cells (IC50 9.2 microM), respectively.
