Synthesis and antitumor activity of novel duocarmycin derivatives
摘要:
A series of Duocarmycin B-2 analogs bearing simplified right hand segments (Seg-Bs) with the protected phenolic hydroxyl group in left hand segment (Seg-A) was synthesized. Among them, the cinnamoyl derivatives 6c and 6d exhibited potent antitumor activity against in vivo murine tumor models in the wider range of doses without detectable toxic effects than DUMB(2).

In the absence of distamycin A (Dist), hybrids 1 (X=N, CH) selectively alkylate the 3' end of adenine in AT-rich DNA sequences. However, these hybrids can form a heterodimer with Dist to alkylate G residues of predetermined DNA sequences efficiently and with high selectivity.

There is provided a novel pyrrole-imidazole polyamide compound for alkylating the specific base sequence of DNA, the polyamide compound being capable of being synthesized through fewer reaction steps than known hybrid molecules and having a combination of a high reactivity in DNA alkylation and the ability to recognize a sequence. Furthermore, there is provided an alkylating agent and a molecule serving as a drug, the alkylating agent and the molecule containing the polyamide compound.
An indole derivative is represented by general formula (1):
wherein R
1
represents a functional group for alkylating DNA; R
2
represents a hydrogen atom, an alkyl group, or an acyl group; and X represents a divalent group having one constitutional unit or having two or more constitutional units which may be the same or different, the constitutional unit being represented by the following formula:
(wherein m is an integer of 0 to 10), wherein among the constitutional units, a terminal constitutional unit adjacent to R
2
may be a constitutional unit represented by the following formula:
(wherein k is an integer of 0 to 10).
