清除剂

The present invention relates to a process for rapid solution synthesis of a peptide, the process comprising repetitive cycles of steps-: a coupling step, using an excess of an activated carboxylic component to acylate an amino component, a quenching step in which a scavenger is used to remove residual activated carboxylic functions, wherein the scavenger may also be used for deprotection of the growing peptide, one or more aqueous extractions and optionally, a separate deprotection step, followed by one or more aqueous extractions, characterised in that the process comprises at least one step, referred to as step, in which an amine or a thiol comprising a free anion or a latent anion is used as a scavenger of residual activated carboxylic functions.

The investigation also showed that, the antioxidants with same action mechanism, for example, as both radical scavengers, phenol and amine antioxidants are synergistic; but the synergistic effects between two antioxidants with different action mechanism, such as radical scavenging phenol and amine antioxidants, and hydroperoxide decomposing ashless dithiocarbamate, are much stronger, and the heterosynergism between dithiocarbamate and alkylated diphenylamine is outstanding, which can serve as high temperature ashless high performance antioxidant combination; the heterosynergism among three antioxidants with three different action mechanisms, for example, the tri-component combination of alkylated diphenylamine, zinc dithiocarbamate and organic molybdate ester, can achieve excellent antioxidation performance.

研究还表明，具有相同抗氧机理的不同抗氧剂，如酚类和胺类抗氧剂，具有协同作用；不同作用机理的两抗氧剂之间，如自由基清除剂和氢过氧化物分解剂，具有更好的抗氧化协同效果，其中，无灰氨基甲酸酯与烷基化二苯胺抗氧剂具有最佳的抗氧协同效能，可成为高温无灰抗氧剂应用的一个很好选择；不同抗氧机理的三种抗氧剂复合，如烷基化二苯胺，氨基甲酸锌和有机钼酸酯组成的三元复合抗氧剂，具有更为优秀的抗氧化性能。

In addition, like ascorbic acid, an important reducing substrate for H2O2 removal, but unlike diphenylene iodonium, an inhibitor of the H2O2-generating enzyme NADPH oxidase, PD98059 and TFP not only reduced exogenous H2O2 levels in guard cells in light, but also eliminated the H2O2 that had been generated during a dark period and promoted stomatal opening.

另外，和H2O2的产生有关的NADPH氧化酶的抑制剂二苯基碘的作用效果不同，而和H2O2的清除剂抗坏血酸的作用效果类似，PD98059和TFP不仅能够降低光下保卫细胞的外加的H2O2水准，而且还能清除由黑暗条件诱导的已经产生的H2O2，并能引起气孔开放。

This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.

证据主要来自以离体根尖为材料的实验：(1)通过检测干旱胁迫下小麦根尖NOS活性、O〓合成酶活性和ABA积累的时间变化进程，发现ABA积累滞后于ROS和NO的变化；(2)抑制剂实验表明，NO清除剂和NOS抑制剂可以抑制自然干旱胁迫及渗透胁迫诱导的小麦根尖ABA积累，ROS清除剂抑制自然干旱胁迫诱导的ABA积累而不抑制渗透胁迫诱导的小麦根尖ABA积累；(3)在非胁迫条件下施加外源的ROS或NO可以诱导小麦根尖积累ABA，ROS和NO之间具有协同作用。
