Effects of some analogues of purines, pyrimidines and ammo-acids on the early development ofPlanorbis exustus

Summary

  1. 1.

    The effects of 8-azaguanine, a purine analogue, 2-thiouracil, a pyrimidine analogue and ethionine, an amino-acid analogue, on the various stages of cleavage ofPlanorbis exustus have been studied. The development of eggs was inhibited by these analogues.

  2. 2.

    The effects of these analogues are not reversible: The effects produced by 8-azaguanine, 2-thiouracil and ethionine were not prevented by guanosine, uracil and methionine.

  3. 3.

    Other effects of these analogues have been briefly, discussed and they were compared with those of other agents modifiying the development ofPlanorbis eggs.

  4. 4.

    It is suggested that these analogues bring about their effects by interfering with RNA and protein synthesis.

Zusammenfassung

  1. 1.

    Die Wirkungen von 8-Azaguanin, einem Purin-Analogen, 2-Thiouracil, einem Pyrimidin-Analogen, und Äthionin, einem Aminosäure-Analogen, auf verschiedene Furchungsstadien vonPlanorbis exustus wurden untersucht. Die Entwicklung der Eier wurde durch diese Analogen gehemmt.

  2. 2.

    Die Wirkungen dieser Analogen waren nicht reversibel: die Einflüsse von 8-Azaguanin, 2-Thiouracil und Äthionin wurden durch Guanosin, Uracil und Methionin nicht aufgehoben.

  3. 3.

    Andere Effekte dieser Analogen werden kurz diskutiert und mit denen anderer Agentien verglichen, die die Entwicklung der Planorbis-Eier beeinflussen.

  4. 4.

    Es wird angenommen, daß diese Analogen ihre Wirkungen durch die Beeinflussung der Ribonucleinsäure- und Proteinsynthese hervorbringen.
