Phytotoxic activity of quinones and resorcinolic lipid derivatives

On the basis of the reported phytotoxic activity of sorgoleone and resorcinolic lipids identified from the root extracts of Sorghum bicolor, 8 resorcinolic lipid derivatives and 10 quinones with various side chain sizes were synthesized. The phytotoxicity of the compounds was tested against a monocot and a dicot species. The quinones were phytotoxic, whereas the resorcinolic lipids were not. Of the quinones, 2-hydroxy-5-methoxy-3- pentylcyclohexa-2,5-diene-1,4-dione, having a five-carbon side chain, showed phytotoxic activity similar to that of natural compound sorgoleone.

Preparation and structure-activity relationships of novel asterriquinone derivatives

Asterriquinone (ARQ, la) is an antitumor metabolite of Aspergillus terreus IFO 6123. To gain insight into the structure-activity relationships of ARQ, a series of chemically modified derivatives (1 - 6), the ARQ analogues (b - e) and the 2,5-dihydroxy-p-benzoquinone analogues (f - h), were prepared, and cytotoxic activity against mouse leukemia P388 cells investigated. Results indicated that: 1) at least one hydroxy group or acetoxy group in the p-benzoquinone moiety is important to exhibit cytotoxicity; 2) in the p-benzoquinone moiety, a single methoxy group and/or one acetoxy group substitution showed more potent cytotoxicity than when two hydroxy groups are substituted (1); 3) the indole ring is important for the cytotoxicity of ARQ analogues; 4) the 1,1-dimethyl-2-propenyl group in the indole ring is not important for the cytotoxic activity of ARQ.

Dimerization of 2,5-Dihydroxybenzoquinones in Water

2,5-Dihydroxybenzoquinones, when heated in water, react to form different types of compounds through dimerization. The features of this unique reaction were clarified using a model compund, 2,5-dihydroxy-3-methyl-benzoquinone. The structures of the products were established by X-ray analysis and spectroscopic means. - Key words: 2,5-dihydroxybenzoquinone; dimerization; furanylidene benzofuranone; 1,4-dibenzofurandione; X-ray analysis

Reactive dyestuffs

Triphendioxazine reactive dyestuffs of the general formula STR1 with the substituent definition given in the description, are outstandingly suitable for dyeing and printing materials containing hydroxyl groups or amide groups. They give red dyeings with high wet- and light-fastnesses.

Triphendioxazine dyestuffs

Triphendioxazine dyestuffs of the formula STR1 having the substituent meanings specified in the descriptive part, are highly suitable for dyeing and printing hydroxyl- or amido-containing materials, in particular fibre materials, and produce wash-fast dyeings and prints.
