Current Status of Novel Pyridine Fused Derivatives as Anticancer Agents: An Insight into Future Perspectives and Structure Activity Relationship (SAR).

Cancer is a heterogeneous disease characterized by an abnormal and uncontrolled division of the cells leading to tumors that invade the adjacent normal tissues. After cardiovascular diseases, it is the second most prevalent disease accounting for one in every six deaths worldwide. This alarming rate thus, demands an urgent need to investigate more effective drugs to combat the said disease. Oxygen and nitrogen-based heterocyclic compounds have shown remarkable therapeutic activity towards several diseases, including cancer. In this review, we have attempted to summarize the work done in the last decade (2009-2019), highlighting the anticancer activity of pyrido fused fivemembered heterocyclic ring derivatives. Additionally, we have focused on seven heterocyclic pyridine fused rings: Imidazopyridine, Triazolopyridine, Pyrrolopyridine, Pyrazolopyridines, Thienopyridine, and Isoxazolopyridine. A total of forty-nine compounds have been studied based on their invitro cytotoxic activity and their structure-activity relationship, underlining the anticancer activity of their various pharmacophores and substituents. This review, therefore, aims to draw the attention of the researchers worldwide towards the enormous scope of development of heterocyclic drug compounds, focussing mainly on pyrido fused five-membered heterocyclic rings as anticancer drugs.

Recent advancement in the discovery and development of anti-epileptic biomolecules: An insight into structure activity relationship and Docking.

Although there have been many advancements in scientific research and development, the cause of epilepsy still remains an open challenge. In spite of high throughput research in the field of anti-epileptic drugs, efficacy void is still prevalent before the researchers. Researchers have persistently been exploring all the possibilities to curb undesirable side effects of the anti-epileptic drugs or looking for a more substantial approach to diminish or cure epilepsy. The drug development has shown a hope to medicinal chemists and researchers to carry further research by going through a substantial literature survey. This review article attempts to describe the recent developments in the anti-epileptic agents, pertaining to different molecular scaffolds considering their structure-activity relationship, docking studies and their mechanism of actions.
