Abstract
Aims: Pyrrole derivatives represent a very interesting class as biologically active compounds. The objective of our study was to investigate the cytotoxic and apoptotic effects and antioxidant activity of the newly synthesized pyrrole derivatives.
Method: A series of novel pyrroles and fused pyrroles (tetrahydroindoles, pyrrolopyrimidines, pyrrolopyridines and pyrrolotriazines) were synthesized and characterized using IR, 1H NMR, 13C NMR, MS and elemental analysis techniques. The antiproliferative activity of our synthesized compounds and their modulatory effect apoptotic pathway were investigated. The effect on cellular proliferation and viability was monitored by resazurin assay. Apoptotic effect was evaluated by caspase glo 3/7 assay. Synthesized compounds are then tested for their anticancer activities against three different cell lines representing three different tumor types, namely; the HepG-2 (Human hepatocellular liver carcinoma cell line), the human MCF-7 cell line (breast cancer) and the pancreatic resistant Panc-1 cells. Result: Compounds Ia-e, IIe, and IXc, d showed a promising anti-cancer activity on all tested cell lines. Antioxidant and wound healing invasion assays were examined for promising anticancer candidate compounds.Keywords: Pyrrole, tetrahydroindoles, pyrrolopyrimidine, pyrrolopyridines, cytotoxicity, apoptosis, wound healing and cancer.

Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
Role of natural compounds as anti anti-cancer agents
Cancer is considered the leading cause of worldwide mortality, accounting for nearly 10 million deaths in 2022. Cancer outcome can be improved through an appropriate screening and early detection and through an efficient clinical treatment. Chemotherapy remains an important approach in treatment o f several types of cancers, even though ...read more
