Abstract
:
The efficacy of successful cancer therapies is frequently hindered by the development of drug
resistance in the tumor. The term ‘drug resistance’ is used to illustrate the decreased effectiveness of a
drug in curing a disease or alleviating the symptoms of the patient. This phenomenon helps tumors to survive
the damage caused by a specific drug or group of drugs. In this context, studying the mechanisms of
drug resistance and applying this information to design customized treatment regimens can improve therapeutic
efficacy as well as the curative outcome. Over the years, numerous Multidrug Resistance (MDR)
mechanisms have been recognized and tremendous effort has been put into developing agents to address
them. The integration of data emerging from the elucidation of molecular and biochemical pathways and
specific tumor-associated factors has shown tremendous promise within the oncology community for improving
patient outcomes. In this review, we provide an overview of the utility of these molecular and biochemical
signaling processes as well as tumor-associated factors associated with MDR, for the rational
selection of cancer treatment strategies.

Abstract
A series of new C3-trans-cinnamide linked β-carboline conjugates has been synthesized by coupling between various β-carboline amines and substituted cinnamic acids. Evaluation of their anti-proliferative activity against a panel of selected human cancer cell lines such as A549 (lung cancer), MCF-7 (breast cancer), B16 (melanoma), HeLa (cervical cancer) and a normal cell line NIH3T3 (mouse embryonic fibroblast cell line), suggested that the newly designed conjugates are considerably active against all the tested cancer cell lines with IC50 values 13-45 nM. Moreover, the conjugates 8v and 8x were the most active against MCF-7 cells (14.05 nM and 13.84 nM respectively) and also even potent on other cell lines tested. Further, detailed investigations such as cell cycle analysis, apoptosis induction study, topoisomerase I inhibition assay, DNA binding affinity and docking studies revealed that these new conjugates are DNA interactive topoisomerase I inhibitors.

Abstract
Agents which can recognize and bind specific sequences of DNA offer selective therapy through the modulation of specific transcription factors or genes. Recently, there has been renewed interest in the field of anticancer minor groove binders. This may be attributed to the fact that many compounds of this class have demonstrated significant antitumor activity against a wide variety of cancers in recent clinical trials. This review will discuss the recent efforts to overcome the drawbacks of existing minor groove binding anticancer agents through rational drug design based on scaffolds with known antitumor activity.

Abstract
A series of new 1,2,3-triazolo-phenanthrene hybrids has been synthesized by employing Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. These compounds were evaluated for their in vitro cytotoxic potential against various human cancer cell lines viz. lung (A549), prostate (PC-3 and DU145), gastric (HGC-27), cervical (HeLa), triple negative breast (MDA-MB-231, MDA-MB-453) and breast (BT-549, 4T1) cells. Among the tested compounds, 7d displayed highest cytotoxicity against DU145 cells with IC50 value of 1.5±0.09µM. Further, the cell cycle analysis shown that it blocks G0/G1 phase of the cell cycle in a dose dependent manner. In order to determine the effect of compound on cell viability, phase contrast microscopy, AO/EB, DAPI, DCFDA and JC-1 staining studies were performed. These studies clearly indicated that the compound 7d inhibited the cell proliferation of DU145 cells. Relative viscosity measurements and molecular docking studies indicated that these compounds bind to DNA by intercalation.
