    Abstract:   Objective: This research was conducted to prove and estimate the activity of the newly designed compound by applying quantitative structure–activity relationship (QSAR) study using Vlife molecular design suite (MDS) 2 software on various purine derivatives. These novels scaffolds/candidates, which could have the potential to inhibit 5FSO would represent promising starting points as lead compounds and certainly aid the experimental designing of anticancer drugs.Materials and Methods: Purine derivatives are studied and based on the QSAR study new structures are drawn and predicted the biological activity using the Vlife MDS Software-Module Name: QSAR Plus. Auto dock 1.2.6 software is a suite of automated docking tools. It is designed to predict how small molecules, such a substrate or drug candidates, bind to receptors of the known 3D structure. 5FSO protein preparation and optimization, ligand preparation and optimization, and docking simulations were carried out by using biological databases such as PubChem, Drug Bank, Protein Data Bank.Results: To estimate the activity, computational studies had been applied. In addition, the newly designed compound can be used as a scaffold to design more purine compounds which may be a potent inhibitor of 5FSO protein.Conclusion: The results depict as the newly designed molecules has better binding energy than standard drug and these compounds may possess better anticancer activity.

    Abstract: Objective: Telomeres are protective caps present at the end of the chromosomes and it contains genetic information. From the literature survey, we selected perylene diimides which interact with the telomerase enzyme and possess anticancer activity. Telomestatin a macrocyclic chemical compound that inhibits telomerase activity as well it induces the formation of G-Quadruplex structures in the telomeric region. The main objective of the study was to find the binding affinity of butyl and naphthyl amine derivative of perylene ligands targeting telomerase enzyme for anticancer activity. Telomerase enzyme is responsible for maintaining the length of telomeres and keeping the chromosomes intact longer. Telomeres will become increasingly common with age. Perylene diimides and its derivatives show good biological activity and also in vitro studies possess efficient anticancer agent. The butyl and naphthyl amine derivatives are screened by computational techniques to study regarding binding energy and ligand interactions with respect to the targets.Methods: Butyl and naphthyl amine derivative of perylene diimides is drawn using Accelrys Draw. The structures are retrieved from the previous study. The structures are converted to pdb formats using Discovery Studio Visualizer 4.1. The study was to investigate the binding energy values of butyl and naphthyl amine derivatives of perylene diimides. Auto Dock 4.2 was used to dock the ligand with the targets. The target selected for docking was 3CE5 and 4B18. The results are visualized by Discovery Studio Visualizer 4.1. The results are compared with the standard drug N,N’-bis-(2-(1- piperidino)ethyl)-3,4,9,10-perylene tetracarboxylic acid diimide (PIPER).Results: From the results, butylamine derivative of perylene diimide possesses good binding energy when compared with standard drug PIPER. This result shows that the butylamine will be effective for anticancer therapy. In future, in vivo studies of butylamine derivative of perylene diimide will be carried out.

    Abstract: Objective: Telomerase enzyme which is expressed in detectable levels and its mechanism was that it increases the length when it binds to telomeres. This eventually leads to extension of lifespan of cells and also makes an attractive target for cancer therapy. Perylene diimides bind to telomerase with duplex genomic DNA, and these G-quadruplex ligands are of responsible for binding affinity with respective proteins. Based on the IC50 values of perylene diimides, QSAR has been studied out and the results are elaborated in preliminary research works. From the results of QSAR, the selected perylene ligands are selected for docking choosing telomerase as a target/protein. From the results of in silico studies, new compounds are designed and synthesized accordingly. Now, the objective of the study was to dock the final synthesized compounds with the telomerase protein to study regarding the pKi value using G-quadruplex ligand database (G4LDB). The docked results are visualized using Discovery Studio Visualizer 4.1. The results are compared with the standard N,N’-bis-(2-(1-piperidino)ethyl)-3,4,9,10-perylene tetracarboxylic acid diimide (PIPER) drug and these compounds will be effective for anticancer therapy.Methods: The study was to investigate the docking results of synthesized perylene compounds with the results from G4LDB and visualized by Discovery Studio 4.1 Visualizer. The telomerase proteins selected for the study were extracted from Protein Data Bank, and the proteins selected for the study are 3SC8 and 3CE5. Among the compounds (R1, R2, R3, and R4) screened in G-Quadruplex Ligand Database, compound R3 shows better binding affinity with good pKi value as well the interactions with the protein and ligand show better affinity with the targets and these are compared with the standard drug PIPER drug.Results: Compound R3 possesses the best binding affinity with the target 3CE5 and 3SC8 which shows that the compound will be effective for anticancer therapy.

    Abstract: The human telomere stabilization with G-Quadruplex DNA tends to induce apoptosis. The molecular target of telomere cascade with a rigid molecular may show efficacious to treat cancer. The study of intercalation to human telomeric DNA with proposed ligand can be evaluated by the help of biophysical studies and biological studies. G-Quadruplex is one of the key epigenetic episodes of eukaryotes and prokaryotes, generally found in the telomeric end region, immunoglobulin switch recombination and the lagging strand of the DNA. These chemotherapeutic advances are not enough to maintain a life expectancy of cancer affected patients. A number of G-Quadruplex ligands such as acridine, perylene, and anthraquinones have been synthesized reported and evaluated them for the inhibitor activity. Therefore, translational research can pave the novel prospect to treat cancer in a fundamental way. In that connection, basic research showed G-Quadruplex phenomenon of DNA, which is having a great impact in this chemotherapy.
