Current spectrophotometrically based peroxidase assay methods are based on the production of chromophoric substances at the end of the enzymatic reaction. The ambiguity regarding the formation and identity of the final chromophoric product and its possible reactions with other molecules have raised concerns about the accuracy of these methods. This can be of serious concern in inhibition studies. A novel

Two novel types of supramolecular nanocarriers fabricated by the amphiphilic host–guest inclusion complex formed from water‐solublepillar[6]arene (WP6) and azobenzene derivatives G1 or G2 have been developed, in which G1 is structurally similar to G2 but has an extra phenoxy group in its hydrophobic region. Supramolecularmicelles can be initially formed by WP6 with G1, which gradually transform into

potential of the anthranilamide derivatives and 2, 4-(7//,i//)-quinazolin-dione ring system, including dyes. The relationship between structure and color, dyeing and fastness properties has been studied \ It can be concluded that dyes derived from benzanilide have superior substantively and wash fastness on cotton compared to the other dyes Studied'. Results and Discussions As a part of our program directed

l)-4-phenyl azetidin-2-one were synthesized through the reaction of N-4-[phenyldiazenyl] phenyl}-N-[phenyl methylene] amine with 4-[phenyldiazenyl] aniline. The resulting 3-chloro-4-phenyl-1-4-[phenyldiazenyl] phenyl} azetidin-2-one intermediate in benzene was irradiated in a Pyrex vessel with 350 nm UV light in a photochemical reactor to give the desired derivatives (4a–j). Structures of the new
