| pubmed-article:14695823 | pubmed:abstractText | Work in this laboratory has been involved with the design of aziridinyl quinone-based cancer drugs (PBIs) capable of both recognizing the DNA major groove and cleaving the phosphate backbone upon reduction to the hydroquinone. The hydroquinone species recognizes the major groove of DNA at single base pairs by Hoogsteen-type hydrogen bonding. The present study extends recognition beyond a single base pair by adding amino acid residues to the 3-amino center of the PBI system. Thus, extension with proline or proline-glycine results in phosphate cleavage at 5'-AA-3' with insignificant N(7) guanine alkylation. Molecular models were used to validate the observed sequence specificity. This report also describes the design of PBIs not capable of DNA alkylation. Removal of major groove interactions by methylation or the presence of steric bulk prevented DNA alkylation reactions upon reductive activation. From these studies it was concluded that DNA alkyation was not necessary for PBI cytostatic and cytotoxic activity. For example, linkage of two phenylalanines to the PBI results in highly selective cytostatic and cytotoxic activity against melanoma, although this compound is a weak DNA alkylator. | lld:pubmed |
