prepared by reflux reaction of chalcones with nicotinic acid hydrazide in ethanolic solution. Compounds were confirmed by elemental analyses, IR, 1H NMR and 13C NMR spectral data and were evaluated for antimalarial and antibacterial activity. Compounds 5n (IC50=0.022μM for MRC-2 and IC50=0.192μM for RKL-9) displayed better antiplasmodial activity than the chloroquine (CQ) against chloroquine-sensitive (MRC-2)

Abstract A series of novel chalcone derivatives that contain the 1,1-dichloropropene moiety was designed and synthesized. Bioactivity assays showed that most of the target compounds exhibited moderate to good antiviral activity against tobacco mosaic virus (TMV) at 500 μg/mL. Among the target compounds, compound 7h showed the highest in vivo inactivation activity against TMV with the EC 50 and EC 90
Despite the resurging interest in covalent inhibitors, libraries are typically designed with synthon filtered out for reactive functionalities that can engage a target through covalent interactions. Herein, we report the synthesis of two libraries containing Michael acceptors to identify cysteine reactive ligands. We developed a simple procedure to discriminate between covalent and high affinity non-covalent
Eight bis-chalcone conjugates with lysine linker were synthesized by alkylation reaction and evaluated for the antiproliferative potential. All the newly synthesized derivatives (0-100μM) were first screened against Liver cancer (MHCC-97H), Colorectal cancer (HCT116), and Gastric cancer (TMK1) using CCK-8 assay under the concentrations from 0 to 100μM, suggesting that gastric cancer cell TMK1 is more
