- The synthesis and anti-inflammatory evaluation of 1,2,3-triazole linked isoflavone benzodiazepine hybrids
-
Copper catalyzed azide-alkyne cycloaddition was used for the first time to access a small series of eight novel 1,2,3-triazole linked isoflavone benzodiazepine hybrids. As part of this work, a previously unreported alkyne substituted pyrrolo[1,4]benzodiaz

- Synthesis and biological evaluation of isoflavone amide derivatives with antihyperlipidemic and preadipocyte antiproliferative activities
-
A series of isoflavone amides were designed with isoflavone in place of the scaffold of 2-arylbenzoxazole as cholesterol ester transfer protein (CETP) inhibitors. Twelve new compounds were synthesized, and their inhibitory activities of CETP and preadipocyte proliferation were assayed. The hypolipidemic potency of the most effective compound HY-2c was further tested in vivo by hamster. The results indicate that HY-2c exhibited favorable antihyperlipidemic and preadipocyte antiproliferative activities.

- Development of 3-alkyl-6-methoxy-7-hydroxy-chromones (AMHCs) from natural isoflavones, a new class of fluorescent scaffolds for biological imaging
-
Starting from 7-hydroxyisoflavones, we developed a new class of fluorescent scaffolds, 3-alkyl-6-methoxy-7-hydroxy-chromones (AMHCs, MW ~ 205.19, λab ~ 350 nm, λem ~ 450 nm) via a trial and error process. AMHCs have the advantages of being a small molecular moiety, having strong fluorescence in basic buffers, reasonable solubility and stability, non-toxicity, and are conveniently linked to pharmacophores. AMHCs were successfully used in fluorescence microscopy imaging of cells and tissues. This journal is

- Synthesis of daidzin analogues as potential agents for alcohol abuse
-
Daidzin, the active principle of an herbal remedy for 'alcohol addiction', has been shown to reduce alcohol consumption in all laboratory animals tested to date. Correlation studies using structural analogues of daidzin suggests that it acts by raising the monoamine oxidase (MAO)/mitochondrial aldehyde dehydrogenase (ALDH-2) activity ratio (J. Med. Chem. 2000, 43, 4169). Structure-activity relationship (SAR) studies on the 7-O-substituted analogues of daidzin have revealed structural features important for ALDH-2 and MAO inhibition (J. Med. Chem. 2001, 44, 3320). We here evaluated effects of substitutions at 2, 5, 6, 8, 3′ and 4′ positions of daidzin on its potencies for ALDH-2 and MAO inhibition. Results show that analogues with 4′-substituents that are small, polar and with hydrogen bonding capacities are most potent ALDH-2 inhibitors, whereas those that are non-polar and with electron withdrawing capacities are potent MAO inhibitors. Analogues with a 5-OH group are less potent ALDH-2 inhibitors but are more potent MAO inhibitors. All the 2-, 6-, 8- and 3′-substituted analogues tested so far do not inhibit ALDH-2 and/or have decreased potencies for MAO inhibition. This, together with the results obtained from previous studies, suggests that a potent antidipsotropic analogue would be a 4′,7-disubstituted isoflavone. The 4′-substituent should be small, polar, and with hydrogen bonding capacities such as, -OH and -NH2; whereas the 7-substituent should be a straight-chain alkyl with a terminal polar function such as -(CH 2)n-OH with 2≤n ≤6, -(CH2) n-COOH with 5≤n ≤10, or -(CH2)n-NH 2 with n ≥4.
