Phosphatidylinositol-3-kinase α (PI3Kα) is a ubiquitous intracellular enzyme, mainly involved in intracellular signaling pathways, promotes cellular growth, proliferation, and differentiation. Therefore, inhibition of PI3K can be a hotspot in molecular targeted therapy for the treatment of cancer. The present research work involves molecular docking studies performed to screen derivatives of urea and thiourea bearing thieno [3,2-d]-pyrimidines against the active site of PI3K enzyme using MOE.2008.10. The designed structures (6a-f) and (7a-j) were synthesized by the facile synthetic methods and evaluated for their anticancer activity against HT-29 and MCF-7 cell lines and inhibitory activity against PI3Kα enzyme...

Reserpine, an indole alkaloid commonly used for hypertension, is found in the roots of Rauwolfia serpentina. Although the root extract has been used for the treatment of cancer, the molecular mechanism of its anti-cancer activity on hormonal independent prostate cancer remains elusive. Therefore, we evaluated the cytotoxicity of reserpine and other indole alkaloids, yohimbine and ajmaline on prostate cancer cells (PC3) using MTT assay. We investigated the mechanism of apoptosis using a combination of techniques including acridine orange/ethidium bromide staining, high content imaging of Annexin V-FITC staining, flow cytometric quantification of the mitochondrial membrane potential and reactive oxygen species (ROS) and cell cycle analysis...

Caffeine represents the most used psychoactive drug in the world acting as a non-selective adenosine receptor antagonist. It exerts an anti-cancer role in glioblastoma multiforme (GBM). This neoplasia is characterized by extensive hypoxic foci triggering hypoxia-inducible factors (HIFs) expression. Among these factors, HIF-1α performs a crucial role in the induction of vascular endothelium growth factor (VEGF), a key player in angiogenesis and cell migration. In this work, we have investigated whether caffeine counteracts GBM progression by modulating hypoxic event...

Pim kinases, also known as Serine/Threonine kinases, are intensively studied protein drug targets in cancer research. They play crucial role in the regulation of signal transduction cascades that promote cell survival, proliferation and drug resistance. Pim kinases are overexpressed in several hematopoietic and solid tumors and support in vitro/in vivo malignant cell growth and survival, through cell cycle regulation and inhibition of apoptosis. Pim kinases do not have an identified regulatory domain, as they are constitutively active...

Amygdalin is a cyanogenic glycoside which is described as a naturally occurring anti-cancer agent. In 1830s, French chemists Robiquet and Boutron-Charlard isolated amygdalin from bitter almonds. Apoptosis is an important mechanism in cancer treatment by amygdalin. Amygdalin can probably stimulate apoptotic process in cancerous cells by increasing activity of Bax (pro-apoptotic protein) and caspase-3 and decreasing expression of Bcl-2 (anti-apoptotic protein). Amygdalin promotes arrest of cell cycle in G0/G1 phase followed by decreasing number of S and G2/M phase cells...

Lung cancer is the most prevalent cancer and a high fatality disease. Despite all therapeutic approaches available, drug resistance and excessively toxic effects of chemotherapy agents for patients remain as obstacles. Therefore, we proposed the design of new drugs integrating immunotherapeutic and conventional cytotoxic effects as a powerful strategy in the treatment of cancer. Antineoplastic phospholipids combine both of these activities by affecting lipid metabolism and signaling through lipid rafts. Therefore, they emerge as interesting scaffolds for designing new drugs...
