The naturally occurring anticarcinogens flavone and alpha-angelicalactone incorporated separately and simultaneously in the diet at 0.5, 0.1, 0.05 and 0.01% w/w, were studied with respect to their effects on oesophageal, gastric, intestinal, colonic and hepatic (i) glutathione S-transferase (GST) enzyme
A direct highly diastereo- and enantioselective asymmetric vinylogous Mannich-type (AVM) reaction of aldimines with nonactivated natural α-angelica lactone has been successfully developed. It was demonstrated that the nonactivated natural α-angelica lactone is a useful vinylogous nucleophile to give the chiral
The effects of alpha-angelica lactone (alpha-AL), butylated hydroxyanisole (BHA), and beta-naphthoflavone (beta-NF) on the amount of benzo(alpha)pyrene (BP) metabolite:DNA adducts formed in the forestomach, lung, and liver of ICR/Ha mice were investigated 48 hr after p.o. administration of BP. BP

The first organocatalytic asymmetric assembly of Morita-Baylis-Hillman carbonates of isatins and α-angelica lactone has been studied, affording multifunctional products containing two valuable pharmacophores and vicinal quaternary chiral centers in high stereoselectivity (up to 92% ee, dr >95:5).
Paraoxonase1 (PON1) is a HDL bound enzyme and many of the anti-atherogenic properties of HDL are attributed to PON1. The enzyme precise mechanism of protective action and its endogenous substrate remain elusive. PON1 hydrolyzes organophosphates, arylesters and lactones, whereas the
