Anti-Cancer Agents in Medicinal Chemistry (Formerly Current Medicinal Chemistry - Anti-Cancer Agents) - Volume 18, Issue 10, 2018

Nitrogen-containing five-membered heterocyclics play a vital role in pharmaceuticals as well as medicinal chemistry. Pyrazolines play a significant role among other heterocycles because of their therapeutic and pharmacological properties. 2-Pyrazolines displayed a wide variety of biological activities such as anticancer, antiepileptic, anti-aids, antimalarial, insecticidal, antitubercular, etc. and they are used as pesticides, herbic Read More

Background: A glioblastoma is a primary CNS tumor that is more aggressive and lethal than other brain tumors. Its location, rapid proliferation, invasive growth, angiogenesis and immunosuppression are the main factors that limit its treatment, making it a major challenge to neuro-oncology. Objective: This study investigated the in vitro effects of the alkaloid dihydrochelerythrine (DHC), which is extracted from Zanthoxylum st Read More

Background: Arylidene indanones have attracted a great deal of interest due to their outstanding therapeutic applications. In particular, considerable research has pointed out the importance of arylidene indanones in the field of cancer research. Objective: The aim of the current work was to design and synthesize arylidene indanone-based anticancer agents. Method: New arylidene indanones were obtained via th Read More

Background: P. mucronata (Pm) comes from South America, Brazil and is characterized as “Maracujá de Restinga”. It is used in folk medicine for its soothing properties and in treating insomnia. Objective: The present study for the first time analyzed the antioxidant and cytotoxicity of the hydroalcoholic leaves extract and fractions from Pm. Method: The cytotoxicity test will be evaluated by different assays (MTT and CV) ag Read More

Background: Based on the structure of RC-121 (D-Phe-c (Cys-Tyr-D-Trp-Lys-Val-Cys)-Thr-NH2, - synthetic derivatives of somatostatin), some analogs were synthesized and tested for in vitro cytotoxic and antioxidant activity. Objectives: The new analogs were modifyed at position 5 with Dap (diaminopropanoic acid), Dab (diaminobutanoic acid) and Orn and at position 6 with the unnatural amino acids Tle (t-leucine). Methods: Read More

Background: Modified nucleosides established a prime role as therapeutic drugs. Objective: Design and synthesis of novel truncated carbocyclic nucleoside with modified nucleobases and evaluation of their anticancer properties. Methods: Novel truncated carbocyclic nucleoside analogues were synthesized from a versatile starting material D-ribose. The synthetic route includes stereoselective Grignard reaction, Wittig olefin Read More

Background: Caffeine represents the most used psychoactive drug in the world acting through different mechanisms of action and on several molecular targets. 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 e Read More

Background: Many studies suggested that Acetylcholine (ACh) might serve as an autocrine/ paracrine growth factor in several types of tumors or tumor cell lines. High levels of Acetylcholinesterase (AChE) activity have been reported in primary brain tumors, ovarian, colon and lung tumors. Objectives: The role of cholinergic signaling needs to be clarified in in leukemia. Method: K562 cells were derived from a chronic myelog Read More

Objective: Cell resistance to doxorubicin and its toxicity to healthy tissue reduce its efficiency. The use of cell-penetrating peptides as drug delivery system along with doxorubicin is a strategy to reduce its side effects. In this study, the influence of poly-L-arginine on doxorubicin cytotoxicity, its cellular uptake and doxorubicin-induced apoptosis on human prostate cancer DU145 cells are assessed. Methods: The cytotoxicity of do Read More

Background: Acute myeloid leukemia (AML) represents the largest number of annual deaths from hematologic malignancy. In the United States, it was estimated that 21.380 individuals would be diagnosed with AML and 49.5% of patients would die in 2017. Therefore, the search for novel compounds capable of increasing the overall survival rate to the treatment of AML cells is urgent. Objectives: To investigate the cytotoxi Read More

Background: RM-133 belongs to a new family of aminosteroid derivatives demonstrating interesting anticancer properties, as confirmed in vivo in four mouse cancer xenograft models. However, the metabolic stability of RM-133 needs to be improved. After investigation, the replacement of its androstane scaffold by a more stable estrane scaffold led to the development of the mestranol derivative RM-581. Methods: Using solid- Read More

Background: In the traditional system of medicine, leaves and stem bark of Euphorbia tithymaloides L. have been used for the treatment of asthma, persistent coughing, laryngitis, skin diseases and mouth ulcers. Some studies have reported the anti-inflammatory and antimicrobial activities of phytochemicals from the leaf; however, the analysis of essential oil and its antioxidant property is still unexplored. Methods: Read More

Background: Multi-kinase inhibitor sorafenib showed dramatic effects in acute myeloid leukemia (AML) cells harboring fms-related tyrosine kinase 3-internal tandem duplication (FLT3-ITD) mutation. However, FLT3-ITD mutation only occurs in 25% of AML cases. The therapeutic effects of sorafenib in AML patients without FLT3-ITD are still in need of further investigation. Methods: A young AML patient with central nervous s Read More

Background: One of the most promising strategies to develop multi-targeted anticancer therapeutics is to introduce to the structure of a potential drug two or more pharmacophores (functional groups or structural fragments), which have antiproliferative, proapoptotic or antimetastatic properties acting via different mechanisms. Objective: To design, synthesize and perform screening of a novel hybrid anticancer compou Read More
