Tikhomirov, Alexander S. published the artcileAmides of pyrrole- and thiophene-fused anthraquinone derivatives: a role of the heterocyclic core in antitumor properties, Category: piperidines, the main research area is naphthoindole carboxamide preparation human SAR antitumor mol docking; anthrathiophene carboxamide preparation human SAR antitumor mol docking; Anthraquinone; Antitumor activity; Apoptosis; DNA binding; Indole; Multidrug resistance; Reactive oxygen species; Structure-activity relationship; Thiophene; Topoisomerase 1.
A new series of naphtho[2,3-f]indole-3-carboxamides I [R1 = Me; R2 = (3S)-3-aminopyrrolidin-1-yl, ((3S)-pyrrolidin-3-yl)amino, 4-amino-1-piperidyl, etc.; X = NH, NMe, NBn, etc.;] and anthra[2,3-b]thiophene-3-carboxamides I [R1 = H, X = S] was synthesized via coupling the resp. acids with cyclic diamines and dissected the role of the heterocyclic core in antitumor properties. New compounds demonstrated a submicromolar antiproliferative potency close to doxorubicin (Dox) against five tumor cell lines of various tissue origin. In contrast to Dox, the new compounds were similarly cytotoxic for HCT116 colon carcinoma cells (wild type p53) and their isogenic p53 knockout counterparts. Compound I [R1 = Me; R2 = (3S)-3-aminopyrrolidin-1-yl; X = NH] formed more affine complexes with DNA duplex than furan and thiophene analogs, a property that could be translated into a stronger inhibition of topoisomerase 1 mediated DNA unwinding. At tolerable doses the water soluble derivative I [R1 = Me; R2 = (3S)-3-aminopyrrolidin-1-yl; X = NH] significantly inhibited tumor growth (up to 79%) and increased the lifespan (153%) of mice bearing P388 lymphoma transplants.
