Data are presented which suggest that cigarette smoking, and to a lesser degree, urban pollution as indexed by benzo[a]pyrene are etiologic factors in the causation of lung cancer. The dose--response relationship to benzo[a]pyrene to lung cancer death rate in the urban community was estimated by using data on lung cancer deaths among coke oven workers. It appears to be an excess of 2--5 mumg/m3...

Indenoisoquinolines are topoisomerase (Top) I inhibitors developed to overcome some of the limitations of camptothecins and expand their anticancer spectrum. Bis-1,3-{(5,6-dihydro-5,11-diketo-11H-indeno[1,2-c]isoquinoline)-6-propylamino}-propane bis(trifluoroacetate) (NSC 727357) is a novel dimeric indenoisoquinoline derivative with potent antiproliferative activity in the NCI-60 cell line pane...

The design, synthesis and anti-mycobacterial activities of 23 conformationally-constrained indeno[2,1-c]quinolines against Mycobacterium tuberculosis H37Rv is reported. Based on a structural comparison with the anti-TB TMC207 we have devised a synthetic methodology for making new conformationally-constrained indeno[2,1-c]quinoline analogs (Fig. 1), by retaining the biologically significant quin...

The metabolism of [Wlbenzo(a)pyrene with isolated hepatocytes from 3-methylcholanthrene-treated rats was examined with the aid of high pressure liquid chromatography. Covalent binding of [SHlbenzo(a)pyrene metabolites to the intracellular DNA was investigated. The effects of (Ynaphthoflavone, salicylamide, trichloropropene oxide, and diethylmaleate, individually or combined, on the metabolism a...

The synthesis and docking studies of novel benzo[b][1,8]naphthyridines is discribed. The docking studies show that the derivatives prefer to bind the AT-rich region of double stranded DNA (ds-DNA). The maximum binding energy -7.16 (kcal/mol) was observed for benzo[b][1,8]naphthyridine-5-thiol 5a and it is a better candidate as an enantioselective binder to ds-DNA than the other derivatives of b...

Selective synthesis of benzo[f]tetraphenes or benzo[g]chrysenes was achieved via aromatic C-F bond cleavage and unprecedented regioselective C-C bond formation depending upon the choice of aluminium reagents. On treatment with AlCl3, 2-(biphenyl-2-yl)-1-fluoronaphthalenes afforded exclusively benzo[f]tetraphenes via C-C bond formation on the carbon atom γ to the original position of the fluorin...
