4-Hydroxy-5-methoxy-2,3-dihydro-1H-[1,3]benzodioxolo[5,6-c]pyrrolo[1,2-f]-phenanthridium chloride (NK314) is a benzo[c] phenanthridine alkaloid that inhibits topoisomerase IIα, leading to the generation of DNA double-strand breaks (DSBs) and activating the G(2) checkpoint pathway. The purpose of the present studies was to investigate the DNA intercalating properties of NK314, to evaluate the DN...

A hydrophobic-bentonite catalyst (cetyltrimethyl ammonium bromide-bentonite) has been used as a very mild, neutral, eco-friendly, reusable, non-toxic, low-cost and easily available catalyst. It was prepared by replacing the exchangeable Na+ cations of a homoionic Na–bentonite with cetyltrimethyl ammonium bromide (CTMAB) cations. The catalyst was characterized by XRD, BET and SEM. The...

ZSM-11 zeolite was synthesized by hydrothermal treatment and cerium ion was incorporated by the ion exchange method.  The catalytic activity of cerium modified ZSM-11 zeolite was tested for the one-pot synthesis of 4H-pyran derivatives by cyclocondensation of aromatic aldehyde, malononitrile, and ethyl acetoacetate. The synthesized catalyst was characterized by Po...

In this work, various 3-cyano-4-aryl-4H-pyran derivatives were prepared efficiently through a one-pot,multicomponent synthesis between aromatic aldehyde, malononitrile and acetophenone derivativesor ethyl acetoacetate using Fe3O4/EDTA magnetic nanocatalyst and ethanol as solvent. The reactionswere completed at room temperature in 10 min using 5 mg of catalyst and 2 mL of solvent to prepare1 mmo...

Ziziphus mauritiana is an edible fruiting plant commonly found in Asia. In Indonesia, this grows wild and thrives on the islands of Bali, Lombok, Sumbawa. Although it has good potential as food medicinal ingredient, fruits Z. are underutilized have almost no economic value. Information about bioactivity chemical content fruit limited. To evaluate its possibility being developed functional food,...
