Ureas of the structure ##EQU1## WHEREIN X is F or OCH.sub.3 ; Y is O or NH; m is 0, 1 or 2, and n and n' each are 0 or 1, Are useful in prevention of ozone damage to plants.
Ureas of the structure: ##STR1## WHEREIN X is F or Cl or OCH.sub.3 ; Y is O or NH; m is 0, 1 or 2 and N and n' each are 0 or 1 with the proviso that if n' is 1, X is not Cl and if Y is O, X is not Cl are useful in prevention of ozone damage to plants.
结构区域:##STR1## 其中 X 为 F、Cl 或 OCH.sub.3;Y 为 O 或 NH;m 为 0、1 或 2,N 和 n' 各自为 0 或 1,但若 n' 为 1,则 X 不为 Cl,若 Y 为 O,则 X 不为 Cl,这些区域对于预防臭氧对植物的损害是有用的。

N-[2-(2-oxo-1-imidazolidinyl)ethyl]-3-phenylurea and analogs are useful for protecting against oxygen-derived free radical damage in mammals, by inducing endogenous antioxidant enzymes, including superoxide dismutase, in mammals.
synthesized a set of aryl carbamate, pyridyl urea, and aryl urea cytokinine analogs with alkyl and chlorine substitutions and tested their antiproliferative activity in MDA-MB-231, A-375, and U-87 MG cell lines, and cytoprotective properties in H2O2 and CoCl2 models. Aryl carbamates with the oxamate moiety were selectively anti-proliferative for the cancer cell lines tested, while the aryl ureas were inactive
A plant, the nuclear genome of which is transformed with a recombinant DNA sequence encoding a superoxide dismutase which renders the plant stress-resistant. The recombinant DNA sequence also optionally encodes a targeting peptide, fused to the superoxide dismutase, so that the superoxide dismutase is expressed in the cytoplasm of the plant's cells and is subsequently targeted to mitochondria or chloroplasts of the plant's cells or is secreted, via the endoplastic reticulum, from the plant's cells.
一种植物,其核基因组被一种编码超氧化物歧化酶的重组 DNA 序列转化,从而使该植物具有抗逆性。重组 DNA 序列还可选择编码与超氧化物歧化酶融合的靶向肽,从而使超氧化物歧化酶在植物细胞的细胞质中表达,随后靶向植物细胞的线粒体或叶绿体,或通过内质网从植物细胞中分泌出来。
