Theoretical study of the sequence specificity in the covalent binding of the antitumor drug CC-1065 to DNA.
نویسندگان
چکیده
A theoretical modelling is presented of the covalent adducts of the antitumor agent CC-1065 with B-DNA. The optimal complexes are obtained by energy minimisation, taking into account full structure flexibility, including the flexible rings of the ligand and DNA. The binding preference of CC-1065 with respect to base sequence is studied. The results obtained elucidate the origin of the preference for two AT base pairs on the 5'side of the modified adenine. The modifications of the DNA structure upon ligand covalent binding are discussed.

Characterization of an adduct between CC-1065 and a defined oligodeoxynucleotide duplex.
CC-1065 is a potent antitumor antibiotic produced by Streptomyces zelensis. The drug binds covalently through N-3 of adenine and lies within the minor groove of DNA. Previous studies indicated that CC-1065 reacted with adenine in DNA to yield a thermally labile product that could be used to reveal its sequence specificity. These studies also provided insight into a DNA sequence (5'-CGGAGTTAGGGG...
متن کاملMechanism of interaction of CC-1065 (NSC 298223) with DNA.
CC-1065 (NSC 298223), a potent new antitumor antibiotic produced by Streptomyces zelensis, interacts strongly with double-stranded DNA and appears to exert its cytotoxic effects through disruption of DNA synthesis. We undertook this study to elucidate the sites and mechanisms of CC-1065 interaction with DNA. The binding of CC-1065 to synthetic and native DNA was examined by differential circula...
متن کاملBINDING OF THE ANTITUMOR DRUG ADRIAMYCIN TO DNA-HISTONE COMPLEXES
Isotherms of the binding of the anthracycIine antibiotic, adriamycin (adriblastin), to DNA histone complexes was studied by means of spectroscopic analysis. The results indicated that: (a) binding of adriamycin to histones reduced the interaction of histones with DNA, (b) binding of the drug to DNA did not change the binding affinity of histone to DNA and, (c) in the explored binding range...
متن کاملCC-1065 and the duocarmycins: unraveling the keys to a new class of naturally derived DNA alkylating agents.
Key studies defining the DNA alkylation properties and selectivity of a new class of exceptionally potent, naturally occurring antitumor antibiotics including CC-1065, duocarmycin A, and duocarmycin SA are reviewed. Recent studies conducted with synthetic agents containing deep-seated structural changes and the unnatural enantiomers of the natural products and related analogs have defined the s...

AS-I-145 is a novel achiral seco-amino-cyclopropylbenz[e]indolone (seco-amino-CBI) analogue of duocarmycin that has evolved from an alternative strategy of designing CC-1065/duocarmycin agents lacking the characteristic chiral center of the natural agents. The sequence specificity of this compound was assessed by a Taq polymerase stop assay, identifying the sites of covalent modification on pla...
