potential of azaaurones as dual‐stage antimalarial agents was investigated by assessing the effect of a small library of azaaurones on the inhibition of liver and intraerythrocytic lifecycle stages of the malariaparasite. The whole series was screened against the blood stage of a chloroquine‐resistant Plasmodium falciparum strain and the liver stage of P. berghei, yielding compounds with dual‐stage activity

A novel compound of the formula:
wherein ring Q is an optionally substituted pyridine ring;
One of R0, R1 and R2 is —Y0—Z0, and the other tow groups are a hydrogen, a halogen, an optionally substituted hydroxy group, a hydrocarbon group that may be an optionally substituted hydrocarbon group or an acyl group;
Y0 is a bond or an optionally substituted bivalent hydrocarbon group;
Z0 is a basic group which may be bonded via oxygen, nitrogen, —CO—, —CS—, —SO2N(R3)— (where R3 is hydrogen or an optionally substituted hydrocarbon group), or S(O)n (wherein n is to 0, 1 or 2);
......... is a single bond or a double bond, or a salt thereof, which has an excellent LDL receptor up-regulating, blood-lipids lowering, blood-sugar lowering and diabetic complication-ameliorating activity.

isosteric counterparts, azaaurones and N-acetylazaaurones, against Mycobacterium tuberculosis. Aurones were found to be inactive at 20 μm, whereas azaaurones and N-acetylazaaurones emerged as the most potent compounds, with nine derivatives displaying MIC99 values ranging from 0.4 to 2.0 μm. In addition, several N-acetylazaaurones were found to be activeagainst multidrug-resistant (MDR) and extensively drug-resistant

The synthesis of aromathecins, substituted 12H-5,l la-diazadibenzo[b,h]fluoren- 11 -ones is described. Use of these cytotoxic compounds and pharmaceutical compositions containing them for the treatment of cancer is described. Two novel processes for the synthesis of this system and a series of 14-substituted aromathecins as novel cytotoxic, topoisomerase I poisons are described.
