| 内容記述 | Cytokinin activities of trans- and cis-zeatins (1 and 2), N^6-(Δ^2-isopentenyl)-adenine (3), their 1'-methyl derivatives [(1'R)-1,(1'S)-1,(1'R)-2OH-1,(1'S)-2OH-1,(1'R)-2,(1'S)-2,(1'R)-3,and (1'S)-3,listed in Table 1], and of their 9-β-D-ribofuranosides [4,(1"R)-4,(1"S)-4,5,(1"R)-5,(1"S)-5,6,(1"R)-6,and (1"S)-6,listed in Table 1] except for those of (1'R)-2OH-1,and (1'S)-2OH-1,assayed by lettuce seed germination, are summarized, and structure-activity relationships are reviewed. (1) 1'- or 1"- Methylation in 1,2,4,and 6 resulted in slightly less active (1'R)-1,(1'R)-2,(1"R)-4,and (1"R)-6,respectively, and did in much less active (1'S)-1,(1'S)-2,(1"S)-4,and (1"S)-6,respectively. However, 1'-methylation gave no effect on 3 : (1'R)-3 and (1'S)-3 were nearly as active as 3. On the other hand, 1"-methylation in 5 gave slightly more active (1"R)-5 and completely inactive (1"S)-5. The 2-hydroxy derivative (1'R)-2OH-1 was more active than (1'S)-2OH-1. Thus, all the R-enantiomers were more active than the corresponding S-enantiomers, respectively. (2) The trans-isomers [1,(1'R)-1,(1'S)-1,4,(1"R)-4,and (1"S)-4] were more active than the corresponding cis-isomers [2,(1'R)-2,(1'S)-2,5,(1"R)-5,and (1"S)-5], respectively. (3) Hydroxylation at the 2-position of the purine ring in (1'R)-1 and (1'S)-1 gave much less active (1'R)-2OH-1 and (1'S)-2OH-1,respectively. (4) Ribosidations at the 9-position in 1,(1'R)-1,(1'S)-1,2,(1'R)-2,(1'S)-2,3,(1'R)-3,and (1'S)-3 all reduced the cytokinin activity. In the cis series, 5 still possessed a very weak cytokinin activity, but its 2'-deoxy derivative [9-(2'-deoxy-β-D-ribofuranosyl)-cis-zeatin (2'H-5)] did not exhibit any cytokinin activity even at the highest concentration tested. | |||||||||||||||||||||||||||||
