Epigenetic mechanisms are essential for normal development and maintenance of adult life. Disruption of epigenetic processes results in deregulated gene expression and leads to life-threatening diseases, in particular, cancer. Global epigenetic alterations are a hallmark of cancer. Cancer epigenetics revealed the deregulation of all components of the epigenetic machinery including DNA methylati...

In this article we review the biological activity of analogs of the antitumor drug cisplatin that contain chiral amine ligands. Interaction with DNA and formation of cross-links with adjacent purine bases are considered to be the crucial steps in the antitumor activity of this class of complexes. Because double-helical DNA has a chiral structure, interaction with enantiomeric complexes of plati...

The chemical and biological diversity of the marine environment is immeasurable and therefore is an extraordinary resource for the discovery of new anticancer drugs. Recent technological and methodologic advances in structure elucidation, organic synthesis, and biological assay have resulted in the isolation and clinical evaluation of various novel anticancer agents. These compounds range in st...

Repurposing refers to the reuse of conventional drugs with distinct indications for new applications in order to speed up drug development by capitalizing on previous knowledge and safety data. A prominent example is the proposal to implement anthelminthics, such as mebendazole, niclosamide and pyrvinium pamoate, as novel anticancer drugs. Numerous studies have demonstrated activity of these ag...

Over the years, the invention of new compounds are isolated by using advanced technology has expanded significantly. There are number of compounds developed from marine environment for the treatment of various diseases. Increasing evidence suggested that anticancer drug discovery leads from the marine environment. This book combines the knowledge about the compounds isolated from marine environ...

Nitroxides are stable free radicals that contain a nitroxyl group with an unpaired electron. In this paper, we present the properties and application of nitroxides as antioxidants and anticancer drugs. The mostly used nitroxides in biology and medicine are a group of heterocyclic nitroxide derivatives of piperidine, pyrroline and pyrrolidine. The antioxidant action of nitroxides is associated w...

Apoferritin derived from the native protein ferritin was employed to encapsulate anticancer drugs cisplatin and carboplatin.

The therapeutic safety of an anticancer drug is one of the most important concerns of the physician treating the cancer patient. Half maximal inhibitory concentration (IC50) and hillslope are usually used to represent the strength and sensitivity of an anticancer drug on cancer cells. The therapeutic safety of the anticancer drug can be assessed by comparing the IC50 and hillslope of anticancer...

Background: Infertility problem affects young couples. One of the known causes of spermatogenic disorder is chemotherapy in patients with cancer. Since dividing cells are mainly affected by anticancer drugs, the aim of the present study is to investigate the preventive effect of GnRH antagonist on spermatogenic cell apoptosis produced by anticancer drug. Materials and Methods: In the present st...
