Abstract
There has been a concerted attempt to produce more effective anti-tumour agents based on the widely-used cancer chemotherapeutic agent, cisplatin. One interesting approach is to attach a DNA-affinic chemical group to the cisplatin molecule. This could result in a more efficient binding to the biological target, DNA, and produce a different spectrum of Pt-DNA crosslinks that may permit an agent to overcome cisplatin resistance. Acridine Pt complexes, have activity against cisplatin-resistant cells, have a differing DNA sequence selectivity compared to cisplatin and hence, are strong candidates for development as anti-tumour agents. The properties of acridine Pt analogues, especially 9-aminoacridine carboxamide Pt complexes, are reviewed here and the sequence specific interaction of acridine carboxamide Pt complexes with DNA is explored. The 9-aminoacridine carboxamide Pt complexes have a reduced reaction at runs of consecutive guanine nucleotides compared with cisplatin, and form adducts at novel DNA sequences, especially 5'-CGA. The activity of the 9-aminoacridine Pt complexes against cisplatin-resistant cell lines is due to their ability to escape the DNA repair capacity of the cells, through the production of variant DNA adducts. The future prospects for development of acridine carboxamide Pt complexes as cancer chemotherapeutic agents are discussed.

Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
