Effects of cis- and trans-platinum complexes on RNA transcription
Abstract:
Current thinking concerning the anti-cancer actions of platinum complexes view cis-platinum agents as active and trans-complexes as not being anti-neoplastic. It is generally accepted that the active cis forms exert their effects by binding to the DNA template. Data is presented here showing trans-Pt(NH3)2Cl2(trans-PDD) to be much more active than cis-Pt(NH3)2Cl2(cis-PDD) in inhibiting in vitro RNA transcription using both bacterial and eukaryotic enzyme sources. It is further shown that the polymerase enzyme is a much more sensitive target for these platinum agents than the DNA template under the conditions employed.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
