چکیده

A series of forcible curved circular DNAs (cDNAs) were prepared to investigate the recognition features of human Topoisomerase I (hTopo I). The IC(50) can be modulated by the curvature degrees of cDNA. In addition, preferential bindings of hTopo I to cDNA with high curvature have been observed by AFM and EMSA.

Topoisomerase Inhibitors and Types of Them

Objective: In this paper, we have introduced topoisomerase inhibitors, mechanism of action and types of them. DNA topoisomerases are ubiquitous enzymes that catalyze essential enzymes to solve the topological problems accompanying key nuclear processes such as DNA replication, transcription, repair and chromatin assembly by introducing temporary single or double strand breaks in the DNA. Result...

Recognition of specific sequences in DNA by a topoisomerase I inhibitor derived from the antitumor drug rebeccamycin.

We investigated the interaction with DNA of two synthetic derivatives of the antitumor antibiotic rebeccamycin: R-3, which is a potent topoisomerase I inhibitor and contains a methoxyglucose moiety appended to the indolocarbazole chromophore, and its aglycone, R-4. Spectroscopic measurements indicate that R-3 intercalates into DNA and that its carbohydrate domain contributes significantly to re...

Eukaryotic topoisomerase I-DNA interaction is stabilized by helix curvature.

The influence of DNA structure on topoisomerase I-DNA interaction has been investigated using a high affinity binding site and mutant derivatives thereof. Parallel determinations of complex formation and helix structure in the absence of superhelical stress suggest that the interaction is intensified by stable helix curvature. Previous work showed that a topoisomerase I binding site consists of...

Evaluation of Pharmacological Activity of Heterobimetallic Coordination Compounds Containing N, N-Bis (2-hydroxyethyl)-Ethylenediamine on HT29, HeLa, C6 and Vero cells

The present study was conducted in order to investigate the pharmacological activities of three heterobimetallic coordination compounds: [Cd(N-bishydeten)2][Ni(CN)4] (C1), [Cu2(N-bishydeten)2Co(CN)6].3H2O (C2), and K[Cd(N-bishydeten)Co(CN)6].1.5H2O (C3) (N-bishydeten = N,N-bis(2-hydroxyethyl)-ethylenediamine). This paper describes the ability of complexes to inhibit cell growth, cell migration ...
