Two new S-13-oxo analogues (11 and 16) exhibited potent cell growth inhibition in vitro (GI 50: 9 nM and 20 nM). Interestingly, both compounds displayed improved selectivity among different cancer cell lines, in contrast to the natural products antofine and cryptopleurine. Mechanism of action (MOA) studies suggested that R-antofine promotes dysregulation of DNA replication during early S phase, while no similar effects were observed for 11 and 15 on corresponding replication initiation complexes. Compound 11 also showed greatly reduced cytotoxicity against normal cells and moderate antitumor activity against HT-29 human colorectal adenocarcinoma xenograft in mice without overt toxicity. ? 2011 American Chemical Society.[SDGs]SDG312 oxa cryptopleurine; 13 oxa cryptopleurine; 13n boc 11 oxo 13 aza cryptopleurine; 13n boc 13 aza cryptopleurine; 2 (6,7,10 trimethoxy 1,2,3,4 tetrahydrodibenzo[f,h]isoquinolin 3 yl)acetaldehyde; 6,7,10 trimethoxy 3 (2 methoxyvinyl) 1,2,3,4 tetrahydrodibenzo[f,h]isoquinoline; antineoplastic agent; antofine; cryptopleurine; natural product; unclassified drug; animal experiment; animal model; antineoplastic activity; article; cancer cell culture; cancer inhibition; cell cycle S phase; cell strain HT29; colorectal carcinoma; controlled study; cytotoxicity; DNA replication; drug design; drug mechanism; drug potency; drug selectivity; drug synthesis; human; human cell; in vitro study; male; mouse; nasopharynx cancer; nonhuman; prostate cancer; regulatory mechanism; structure activity relation; tumor xenograft; umbilical vein endothelial cell; Alkaloids; Animals; Antineoplastic Agents; Cell Line, Tumor; DNA Replication; Drug Design; Drug Screening Assays, Antitumor; Indoles; Mice; Neoplasm Transplantation; Phenanthrolines; S Phase; Stereoisomerism; Structure-Activity Relationship; Transplantation, HeterologousAntitumor agents 288: Design, synthesis, SAR, and biological studies of novel heteroatom-incorporated antofine and cryptopleurine analogues as potent and selective antitumor agentsjournal article10.1021/jm200330s216680002-s2.0-79960625636
