A dithiocarbamate, named 1-methoxybrassinin (228), along with its 1H-parent, has been isolated from Brassica campestris (Chinese cabbage) infected with Pseudomonas cichorii. These compounds are not derived from glucosinolates (see Section HIE,5) and possess moderate antifungal activity (86CC1077).

The 6-hydroxy-5-n-undecyl derivative of 210 (UHDBT) is a structural analog of ubiquinone. It inhibits the oxidation of succinate and NADH (78MI2 85MI3), blocks the respiratory chain in membranes from Pseudomonas cichorii or Pseudomonas aptata (85MI4), and increases the activity of cytochrome c, about 2-fold (86MI5). It also inhibits the conversion of p-hydroxybenzoic acid (77BBR1536).

It is a novel sesquiterpene81 phytoallexin with significant antifungal activity. The leaves of Lactuca sativa var. capitata (Compositae) were inoculated with pathogenic bacterium Pseudomonas cichorii. The acetone extract from the leaves gave a new compound (0.00084%) which was named lettucenin A. and was assigned the structure (153) on the basis of spectral data. 

Takasugi and collaborators85 have reported the isolation of a sesquiterpenoid phytoalexin, cichoralexin (154) from Cichorium intybus inoculated with Pseudomonas cichorii. Its structure was elucidated by spectroscopic methods.

Stress metab. from the Japanese radish Daikon (Raphanus sativus var. hortensis) (Cruciferae) inoculated with Pseudomonas cichorii. Gum. [a] 0 (c, 0.52 in CHCI3). Unusual hemi-aminal struct. Occurs as a mixt. of diastereoisomers ratio ol-OH P-OH estimated as 2.5 1. 

From sliced yacon tubers after inoculation with the bacterium Pseudomonas cichorii and incubation at 20° for 3 days, then extraction with acetone. Yacon (Polymnia sonchifolia) (Compositae) is cultivated in South America and has recently been introduced into Japan [3445].
