Title NOVEL HETEROCYCLE-CONTAINING AMINO ACID COMPOUND AND USE THEREOF
Abstract Provided is a novel heterocycle-containing amino acid compound that has a metal uptake ability equivalent to mugineic acids and can be less expensively produced than mugineic acids. Also provided are a fertilizer and a plant growth regulating agent each comprising the novel heterocycle-containing amino acid compound. The present invention relates to a heterocycle-containing amino acid compound represented by general formula (1) [wherein: R1, R2 and R3 are the same or different and represent a hydrogen atom or a carboxyl-protecting group; R4 represents a hydrogen atom or a hydroxy-protecting group; R5 represents a hydrogen atom or an amino-protecting group; and n is an integer of 1-3] or a salt thereof and use of the same.
Outline of related art and contending technology BACKGROUND ART
Is a wide variety of plant growth and function of the system responsible for a minute amount of metal elements, and plants and the lack of these trace amounts of metal elements normally cannot grow. For example, iron respiration, photosynthesis, in which the element necessary for DNA synthesis, in particular of chlorophyll biosynthesis is essential for the activity of enzymes like as a central metal, iron and the lack of yellow and leaves to cause chlorosis (iron deficiency diseases and a yellow-white).
On the other hand, the failure is appropriate for use in the distributed to all over the world land soil which occupies about 67%, or the soil where a defective half of it is alkaline. In such an alkaline soil, water-insoluble divalent iron 3 ferric hydroxide (Fe (OH)3) due to the presence in the form of, this root plants cannot be absorbed enough iron and iron deficiency is a problem.
On the other hand, barley, rice, oats, corn plants belonging to the family Gramineae such as, the following formulA:
Represented by the mugineic acid, or compounds of formula (B) :
Represented by 2' - deoxymugineic acid (DMA) secrete root referred to as a chelating agent, forms a complex with iron and the chelating agent is by dissolved iron, the iron complex salt is - specific transporter mugineic acids via captured within the plant (non-patent document 1) are known.
Thus compared with other plants, can be efficiently absorbed iron ions from the alkaline-earth is, in general mugineic acids secretory capacity is low, for example, rice, such as corn, grass could not grow on the alkaline-earth in large number.
Therefore, the inventors of the present invention may be distributed to an alkaline soil in order to allow failure, can be supplied as a fertilizer iron uptake ability are aimed at the development of the chelating agent having.
So far, the present inventors have established the synthesis of the practical mugineic acids (Patent Document 1), then, mugineic acids under alkaline conditions in the growth of the plants belonging to the family Gramineae dramatically effect has been confirmed that the (non-patent document 2).
However, mugineic acids are, as a starting material, for synthesizing the expensive azetidine acid, supplied as a fertilizer mugineic acids is still the problem that the synthesis cost.
Therefore, mugineic acids having an ability to uptake metal equivalent, and, mugineic acids can be produced cheaper chelate compound has been desired.
