Isoguanine (94), which is found in Prioneris wings along with hypoxanthine (92), xanthine (91), and uric acid (95), shows antineoplastic activities (Table VI) (57). Isolation of urocanic acid (137) from this wing material represents the first detection of this histidine derivative in an arthropod (Table VIII). A nonpteridine pigment, xanthommatin (58) (cf. Section II,B,l,b), is found in the larval body of Pieris brassicae (Table V). [Pg.199]

It can be concluded that these equations are very similar to the equations discussed earlier for the 2,6-dichlorobenzoyl subseries as far as the electronic, hydrophobic, and steric influences are concerned. The coefficients of the dummy parameters lead to the conclusion that the 2,6-difluorobenzoyl subseries is about 25 times more active on Pieris brassicae than the 2,6-dichlorobenzoyl series, whereas methyl substitution at the aniline nitrogen systematically decreases the activity by a factor of about five (2. ). [Pg.241]

In the introduction it was stated that the disturbances of the endocuticular matrix of Pieris brassicae larvae by the parent benzoylphenyl urea compound Du 19111 were caused by an influence on chitin formation, thus assigning to the benzoylphenyl ureas an insecticidal position equivalent to that of the fungicidal polyoxins. In the last part of this paper we shall try to adduce arguments supporting that statement. [Pg.253]

After injection, when part of the permeability barriers in the larvae is absent, polyoxin D inhibits the glucose incorporation, but less so than difluben-zuron. The conclusion seems obvious that the intrinsic effects of both compounds are practically identical but that polyoxin D is much more hindered by the permeability barriers present in the Pieris brassicae larvae. On the strength of the evidence presented by Misato and co-workers that polyoxin D is a competitive inhibitor of chitin synthetase, a... [Pg.260]
