  Synthesis and Antitumor Activity of Duocarmycin Derivatives:  A-Ring Pyrrole Compounds Bearing Cinnamoyl Groups

  摘要：

  A series of N-cinnamates of the A-ring pyrrole compound of duocarmycin were synthesized and evaluated for in vitro anticellular activity against HeLa S-3 cells and in vivo antitumor activity against murine sarcoma 180 in mice. The 4'-methoxy- and 4'-BocNH-cinnamates exhibited strong in vitro anticellular activity among the synthesized compounds. The ortho substitution of the 4'-methoxycinnamate did not affect the anticellular activity and contributed to an enhancement of water solubility. Most of the 8-O-(N,N-dialkylcarbamoyl) derivatives of the 4'-methoxycinnamates displayed remarkably superior in vivo antitumor activity to duocarmycin A or B2. Moreover, it is noteworthy that these 8-O-(N,N-dialkylcarbamoyl) derivatives exhibited significant antitumor activity at wider range of doses as compared with the A-ring pyrrole derivatives having the trimethoxyindole skeleton in segment B.

  of DNA interstrand cross-linking agent by synthesizing dimers of a pyrrole (Py)/imidazole (Im)-diamide-CPI conjugate, ImPyLDu86 (1), connected using seven different linkers. The tetramethylene linker compound, 7b, efficiently produces DNA interstrand cross-links at the nine-base-pair sequence, 5'-PyGGC(T/A)GCCPu-3', only in the presence of a partner triamide, ImImPy. For efficient cross-linking by

  我们通过合成吡咯 (Py)/咪唑 (Im)-二酰胺-CPI 偶联物 ImPyLDu86 (1) 的二聚体，使用七种不同的接头连接，开发了一种新型 DNA 链间交联剂。四亚甲基接头化合物 7b 仅在伴侣三酰胺 ImImPy 存在的情况下有效地在九个碱基对序列 5'-PyGGC(T/A)GCCPu-3' 处产生 DNA 链间交联。为了通过 7b 与 ImImPy 进行有效交联，需要两个识别位点之间的一个 AT 碱基对来容纳接头区域。消除 AT 碱基对和插入额外的 AT 碱基对并用 GC 碱基对替换显着降低了交联程度。在存在各种三酰胺的情况下，还检查了 7b 的链间交联的序列特异性。与 ImImPy 相比，ImImIm 的存在略微减少了交联产物的形成。错配伙伴 ImPyPy 和 PyImPy 不与 7b 产生链间交联产物，而 ImPyPy 和 PyImPy 在其与 7b 的匹配位点诱导有效烷基化。使用变性聚丙烯酰胺凝胶电泳和

  clear contrast, the hairpin CPI conjugate 13, which differs from compound 1 in that it lacks one Py unit and possesses a vinyl linker, alkylated the A of 5'-AGTCAG-3' (site 3) efficiently at nanomolar concentrations. Alkylation by compound 14, which has a vinyl linker, occurred at the A of 5'-AGTCCA-3' (site 6) and at several minor alkylation sites, including mismatch alkylation at A of 5'-TCACAA-3'

  A series of A-ring pyrrole compounds of duocarmycin bearing 5-membered heteroarylacryloyl groups (thienylacryloyl and pyrrolylacryloyl) and heteroarylcarbonyl groups were synthesized and evaluated for in vitro anticellular activity against HeLa S3 cells and in vivo antitumor activity against murine sarcoma 180 in mice. Most of the thienylacrylates displayed in vitro anticellular activity equivalent to 4'-methoxycinnamates. Among the 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of methoxy-thienylacrylates, compound 11b, having 4'-methoxy-2'-thienylacryloyl as segment-B (Seg-B), showed remarkably potent antitumor activity and low peripheral blood toxicity in vivo, which were equal to those of 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4'-methoxycinnamates, compared with the A-ring pyrrole derivatives having the trimethoxyindole skeleton in Seg-B. On the other hand, the 2'-pyrrolylacrylates having a double bond as spacer showed 102- to 103-fold stronger anticellular activity than 2'-pyrrolecarboxylates (IC50<0.3nM, 72 h-exposure). The 8-O-acetate and 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 2'-pyrrolylacrylates exhibited an antitumor effect at a lower dose compared with the 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4'-methoxycinnamate (1j). Moreover, it was expected that the antitumor activity would be increased by the strength of the extra hydrogen bond formed between the nitrogen of the pyrrole amido group and DNA, owing to the increase of the number of N-methyl-2'-pyrrolecarboxamide units. However, 2'-pyrrolylacrylates having three N-methyl-2'-pyrrolecarboxamide units showed nearly equal antitumor activity to 2'-pyrrolylacrylates having only one N-methyl-2'-pyrrolecarboxamide unit.

In sharp contrast, another enantiomer, 12R, showed very weak DNA alkylating activity.
