  Synthesis of Cytotoxic Indenoisoquinoline Topoisomerase I Poisons

  摘要：

  A number of indenoisoquinolines were prepared and evaluated for cytotoxicity in human cancer cell cultures and for activity vs topoisomerase 1 (top1). The two most cytotoxic indenoisoquinolines proved to be cis-6-ethyl-5,6,12,13-tetrahydro-2,3-dimethoxy-8,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (21) and cis-6-allyl-5,6,12,13-tetrahydro-2,3-dimethoxy-6,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (22), both of which displayed submicromolar mean graph midpoints when tested in 55 human cancer cell cultures. Two of the most potent top1 inhibitors were 6-(3-carboxy-1-propyl)-5,6-dihydro-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (26) and 6-ethyl-2,3-dimethoxy-8,9-(methylenedioxy)-11H-indeno[1,2-c]isoquinolinium chloride (27), both of which also inhibited top2, unwound DNA, and are assumed to be DNA intercalators. However, two additional potent top1 inhibitors, 6-allyl-5,6-dihydro-2,3-dimethoxy-8,9-(methylenedioxy)-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (13c) and 5,6-dihydro-6-(4-hydroxybut-1-yl)-2,3-dimethoxy-8,9-methylenedioxy-5,11-dioxo-11H-indeno[1,2-c]isoquinoline (19a), did not unwind DNA and did not affect top2, Some of the DNA cleavage sites detected in the presence of the indenoisoquinolines were different from those seen with the camptothecins. The cleavage sites induced by the indenoisoquinolines were reversed by salt treatment, which is consistent with the reversible trapping of top1 cleavable complexes by the indenoisoquinolines. In general, the potencies of the indenoisoquinolines as top1 inhibitors did not correlate with their potencies as cytotoxic agents, as some of the most cytotoxic agents had little if any effect on top1. On the other hand, the most potent of the indenoisoquinolines vs top1 were not the most-cytotoxic. In several cases, moderate activity was observed for both cytotoxicity and activity vs top1.

  imidazolinium carboxylates and imidazolines is described. The palladium catalyst [Pd(CH(R1)N(R2)COR3)Cl]2, or [Pd(allyl)Cl]2, with P(t-Bu)2(2-biphenyl) can mediate the simultaneous coupling of two imines, acid chloride, and carbon monoxide into substituted imidazolinium carboxylates within hours under mild conditions (45 °C, 4 atm of CO). The reaction proceeds in good yield with aryl-, heteroaryl-, and alkyl-substituted

  描述了钯催化的羧酸咪唑啉和咪唑啉的多组分合成。钯催化剂[Pd（CH（R 1）N（R 2）COR 3）Cl] 2或[Pd（烯丙基）Cl] 2，具有P（t- Bu）2（2-联苯）可以在温和条件下（45°C，4 atm CO）在数小时内将两个亚胺，酰氯和一氧化碳同时偶联到取代的咪唑啉代羧酸盐中。用芳基，杂芳基和烷基取代的酰氯，以及各种官能化的亚胺，反应以高收率进行。咪唑啉是通过最初生成的Münchnone中间体形成的，然后将它们与原位生成的质子化的亚胺环加成。胺碱的添加可以阻止Münchnone形成时的催化作用，从而允许随后的第二个亚胺的环加成反应。后者提供了一种复杂的，多取代的咪唑啉鎓羧酸盐的组装方法，并且可以独立控制所有五个取代基。

  Novel site-isolated tetracoordinated molybdenum complexes possessing bis(imido) ligands, [(≡Si–O)2Mo(═NR)2] (R = t-Bu, 2,6-C6H3-i-Pr2), were immobilized on partially dehydroxylated silica (SiO2-200) by a rigorous surface organometallic chemistry protocol.

  A new palladium-catalyzed method to prepare pyrroles directly from three basic building blocks-imines, alkynes, and acid chlorides-is described. This approach provides a straightforward method both to prepare pyrroles in one step and to diversify their structure by simple variation of any of the three starting materials. Mechanistic studies suggest that this process occurs via a complex series of eight

  A palladium-catalyzed multicomponent method for the synthesis of β-lactams from imines, aryl halides, and CO has been developed. This transformation proceeds via two tandem catalytic carbonylation reactions mediated by Pd(PtBu3)2 and provides a route to prepare these products from five separate reagents. A diverse range of polysubstituted β-lactams can be generated by systematic variation of the substrates
