Chalcone is a common scaffold found in many biologically active compounds. The chalcone scaffold was also frequently utilized to design novel anticancer agents with potent biological efficacy. Aiming to continue the research of effective chalconederivatives to treat cancers with potent anticancer activity, fourteen amino chalconederivatives were designed and synthesized. The antiproliferative activity

nitrate esters as the final product. The inhibitorypotency of the synthesized compounds was evaluated against PDE 5 from human platelets and PDE 5A from bovine recombinant and compared with Tadalafil and a standard inhibitor. Compounds AI7, B5, B7, E7 and E8 containing acetyl, nitro, carboxy methyl, hydroxy methyl functionalities exhibit a marked inhibitory effect against human platelet PDE 5. Compounds
Discovery of the Triazolo[1,5-<i>a</i>]Pyrimidine-Based Derivative WS-898 as a Highly Efficacious and Orally Bioavailable ABCB1 Inhibitor Capable of Overcoming Multidrug Resistance
Targeting P-glycoprotein (ABCB1 or P-gp) has been recognized as a promising strategy to overcome multidrug resistance. Here, we reported our medicinal chemistry efforts that led to the discovery of the triazolo[1,5-a]pyrimidine derivative WS-898 as a highly effective ABCB1 inhibitor capable of reversing paclitaxel (PTX) resistance in drug-resistant SW620/Ad300, KB-C2, and HEK293/ABCB1 cells (IC50 =
an urgent need to identify new antibiotics with novel mechanisms that combat antibiotic resistant bacteria. Herein, a series of chalcone derivatives that mimic the essential properties of cationic antimicrobial peptides were designed and synthesized. Antibacterialactivities against drug-sensitive bacteria, including Staphylococcus aureus, Enterococcus faecalis, Escherichia coli and Salmonella enterica

Chalcones containing amino or acetamide groups on ring A and electron donating/withdrawing groups on ring B have been shown to have great cytotoxic potential against human cancer cell lines. In this work, a series of twenty chalcones, including nine 1-(4′-aminophenyl)-3-(substituted aryl)-2-propen-1-ones (1–9), nine 1-(4′-acetamidophenyl)-3-(substituted aryl)-2-propen-1-ones (1a–9a), and two 1-(3′
