  Synthesis of 1-Substituted 3-(Chloromethyl)-6-aminoindoline (6-Amino-seco-CI) DNA Minor Groove Alkylating Agents and Structure−Activity Relationships for Their Cytotoxicity

  摘要：

  A series of racemic 6-amino-seco-cyclopropylindole (seco-CI) compounds was prepared by coupling 1-(tert-butyloxycarbonyl)-3-(chloromethyl)-6-nitroindoline with appropriate acids, followed by nitro group reduction, and evaluated for cytotoxicity in AA8, UV4, EMT6, and SKOV3 cell lines. These compounds are of interest due to their close structural relationship to known AT-specific alkylating agents and cytotoxins and also for the possible construction of stable amine-based prodrugs designed for tumor-specific release. Variations included indole or furan side chains with different substituents, sulfonamide or carboxamide linkers, extension of the minor groove binding side chain to two subunits, and the use of a pyrroylacryloyl unit previously reported to give extremely potent analogues. The parent compound, with a trimethoxyindole side chain, was a moderately potent cytotoxin (IC50 = 0.34 mu M in AA8 cells, 4 h exposure). A single 5-methoxy group on the indole minor groove binding unit was sufficient to maintain potency, and a series of dimethylaminoethoxy-substituted analogues retained the cytotoxicity of the parent compound, while providing increased aqueous solubility.

  Distamycin and nitrogen mustard conjugates, in which the nitrogen mustard unit was coupled to the C-terminus of the pyrrole, were synthesized. The switching of the nitrogen mustard unit from the N-terminus to the C-terminus did not compromise the compound's cytotoxicity. Compound 3, bearing three pyrrole units, was highly toxic to human K562 leukemia cells in vitro with an IC(50) value of 0.03 microM
