Cancer, also known as malignant neoplasm, is a dreadful disease which involves abnormal cell growth having the potential to invade or spread to other parts of the body. Benzimidazole is an organic compound that is heterocyclic and aromatic in nature. It is a bicyclic compound formed by the fusion of the benzene and imidazole ring systems. It is an important pharmacophore and a privileged structure in medicinal chemistry. According to the World Health Organisation (2015 survey), one in six deaths is due to cancer around the globe, accounting for 8.8 million deaths of which 70% of the cases were from low- and middle-income countries. In the efforts to develop suitable anticancer drugs, medicinal chemists have focussed on benzimidazole derivatives. This review article covers the current development of benzimidazole-based anticancer agents along with the synthetic approaches and structure-activity relationships (SAR).

In current review, authors aim to inspire the researcher through structure activity relationship strategy for the finding of safe and effective anticancer molecules. Nowadays cancer is measured as one of the major health problems in human beings in the world from decades. A classes of heterocyclic compounds have been recognized through molecular biology, empirical screening and rational drug development for the evaluation of anticancer molecules however regrettably, till now we could not find a medicine to be entirely active and nontoxic for the treatment of cancer patients. In pointed view, it might be measured that Thiazolidinedione (TZD) heterocyclic compounds are prodigious standing in the synthetic and pharmacological approach of medicinal chemistry. Thiazolidinedione (TZD) nucleus upon the substitution of various functional groups is provides a wide spectrum of biological activity by the use of different mechanism on different target sites. Recently, some of the substituted thiazolidinedione molecules are designed for the treatment of human cancers cell line through different molecular mechanism such as EGFR & Mushroom Tyrosine kinase inhibitor, COX enzyme inhibitors, Histone deacetylase inhibitors, Alpha glucosidase inhibitor, DNA intercalation and Protein tyrosine phosphatase 1B (PTP1B) inhibitor, basically in which PPAR gamma express are in high levels. Peroxisome proliferator-activated receptor (PPAR) gamma ligands effect on apoptosis, cell proliferation and cell differentiation on different types of cell. The most commonly cascades in human cancers cell are Raf/MEK/ERK, Wnt and PI3/Akt. This article highlights and embraces a concise overview of recent approaches for the synthesis of new thiazolidinedione molecules with its structure activity relationship strategy and effects on various signaling pathways, which is responsible for the expresses of cancer cell line activity.

In the present study, authors want to encourage the research exertions through structureactivity relationship for the identification of effective molecules for the treatment of Human immunodeficiency virus because nowadays AIDS is considered as one of the main causes of death in human beings. A diversity of biological resources has been searched and developed for the treatment of HIV but unfortunately, until now, no medicine is found to be fully effective and safe for the cure of patients. Human immunodeficiency virus is a type of lentivirus which causes the infection of HIV and once it enters the human body, it stays for a longer period of time triggering immunodeficiency syndrome. For searching and developing new potent and effective anti-HIV molecules, medicinal chemists have engaged in countless targets with the structure-activity relationship (SAR) of molecules and on this basis, many antiretroviral therapies have been developed to cure HIV infection. Most of these new searched molecules have been found to be clinically active against various types of AIDS patient and auxiliary research in this area may lead to better treatment in the near future. This article encompasses and highlights the recent advancement of innumerable inhibitors laterally through synthetic, semi-synthetic and structure-activity relationship approaches.
