  Antitumor Agents. 284. New Desmosdumotin B Analogues with Bicyclic B-Ring as Cytotoxic and Antitubulin Agents

  摘要：

  We previously reported that the biological activity of analogues of desmosdumotin B (1) was dramatically changed depending on the B-ring system. A naphthalene B-ring analogue 3 exerted potent in vitro activity against a diverse panel of human tumor cell lines with GI(50) values of 0.8-2.1 mu M. In contrast, 1 analogues with a phenyl B-ring showed unique selective activity against P-glycoprotein (P-gp) over-expressing multidrug resistant cell line. We have now prepared and evaluated, 1 analogues with bicyclic or tricyclic aromatic B-ring systems as in vitro inhibitors of human cancer cell line proliferation. Among all synthesized derivatives, 21 with a benzo[b]thiophenyl B-ring was highly active, with GI(50) values of 0.06-0.16 mu M, and this activity was not influenced by overexpression of P-gp. Furthermore, 21 inhibited tubulin assembly in vitro with an IC(50) value of 2.0 mu M and colchicine binding by 7896 as well as cellular microtubule polymerization and spindle formation.

  Sixteen analogues (3-16, 33, and 48) of the unique flavonoid desmosdumotin B (1) were prepared and evaluated as in vitro inhibitors of the human KB cancer cell line and its MDR subclone, KB-VIN. 6,8,8-Triethyl analogues 10-13 showed enhanced KB-VIN selectivity. In particular, 4'-alkyl derivatives 11 (4'-Me) and 12 (4'-Et) showed significant ED50 values of 0.03 and 0.025 mu g/mL, respectively, against KB-VIN with selectivities of > 460- and 320-fold compared with that of KB. This report is the first to describe compounds showing such high activity against MDR cells versus non-MDR cells. The unique activity of 1-analogues is likely MDR-mediated because cotreatment with verapamil, a P-gp inhibitor, partially reversed the selective toxicity of both 1 and 10. Interestingly, only 1-analogues with a naphthalene B-ring (8 and 14) showed significant cytotoxic activity against KB; and other cancer cell lines. Thus, 1-analogues might be a new class of potent drug candidates, especially as 11 and 12 express direct selective action against tumors expressing MDR.
