制备方法与用途

理化性质

赤霉酸又名赤霉素A3,是赤霉素的主要成分。纯品为白色晶体,熔点233—235℃(分解),难溶于,可溶于醋酸乙酯。它可通过从赤霉素中分离得到。与赤霉素相比,其活性更强。

功效作用

赤霉酸是一种广谱性的植物生长调节剂,能够促进作物的生长发育,使其提前成熟、提高产量并改善品质;能迅速打破种子、块茎和鳞茎等器官的休眠状态,促进发芽;减少蕾、花、铃、果实的脱落,提升果实结果率或形成无籽果实。此外,它还能促使某些二年生植物当年开花,并广泛应用于果树、蔬菜、粮食作物、经济作物及稻杂交育种。

注意事项
  1. 赤霉酸溶性较低,在使用前应先用少量酒精或白酒溶解,再加稀释至所需浓度。
  2. 使用赤霉酸处理的作物会增加不孕籽的数量,因此留种田不宜施药。
  3. 用药浓度需控制精确,浓度过高会导致药害。
  4. 遇碱易分解。
生物活性

A-3盐酸盐是强效、细胞渗透性、可逆且ATP竞争性的非选择性激酶拮抗剂。它对PKA(Ki=4.3 μM)、酪蛋白激酶II(Ki=5.1 μM)和肌球蛋白轻链激酶(MLCK,Ki=7.4 μM)具有抑制作用,并且还抑制PKC及酪蛋白激酶I的活性,相应的Ki值分别为47 μM和80 μM。

靶点
  • CK1: 80 μM (Ki)
  • CK2: 5.1 μM (Ki)
  • PKC: 47 μM (Ki)
  • PKA: 4.3 μM (Ki)
体外研究

A-3盐酸盐以ATP竞争性方式抑制肌球蛋白轻链激酶,其Ki值为7.4 μM。此外,它还作为cAMP依赖型蛋白质激酶、cGMP依赖型蛋白质激酶、蛋白激酶C、酪蛋白激酶I和酪蛋白激酶II的ATP竞争性抑制剂,相应的Ki值分别为4.3 μM、3.8 μM、47 μM、80 μM和5.1 μM。
