TL;DR: This paper tries to present some information about the production of some metabolites known as secondary metabolites (allelochemicals) from plants metabolisms pathways and the usage of them.
Abstract: In today's world the usage of useful secondary metabolites derived from plants metabolisms pathways plays important roles in pharmaceutical productions and applications. These metabolites such as Apigenin an anti-infection, anti-viral, anti-carcinogenic derived from Anthemis nobilis plants or Berberine an anti- microorganism, Anti diabetic, anti-inflammatory activity, anti-cancer, LDL cholesterol reducer derived from Berberis aquifolium, are constantly used in pharmaceutics. This paper tries to present some information about some of these metabolites and the usage of them. Аннотация. В совремевнном мире использование вторичныx метаболитов, как продукт метаболизма растений, играет важную роль в фармацевтическом производстве. В данной статье представлена информация о некоторыx вторичныx метаболитаx растений и иx применение в медицине. Такие ценные метаболиты, как апигенин получаемый из Anthemis nobilis, Thymus serpyllum, Achillea millefolium и др. и берберин - из Berberis aquifolium, обладают антимикробной, антивирусной, антиканцерогенной, антивоспалительной активностями. Берберин является антидиабетическим средством и LDL xолестерин редуктором. Ключевые Слова: вторичные метаболиты растений, алкалоиды, фенолы, терпены Introduction. Plants have existed for millions of years and numerous animals and insects have coevolved with them. Undoubtedly one of the brilliant aspect of their surviving in the nature is about the production of some metabolites known as secondary metabolites (allelochemicals) by certain pathways that are known to be produce under harsh conditions. Considerably, herbivorous animals and insects use the plants as a source for their existence while the plants staidly express these metabolites as a defensive mechanism, or even carnivorous plants have the ability to trap insects in the specialized organs, obtaining additional nitrogen and phosphorus in nutrient-poor environments (Stotz et al 1999). The host-plant resistance (HPR) mechanism of plants starts by certain pathways that initiated from gene expression which consequently leads to express compounds such as: Tannins, Alkaloids, Phenols, Resins, etc. Plant secondary metabolites are categorized in three main branches based on their biosynthesis pathways: Phenolic compounds, Terpenes and Nitrogen-containing compounds. It is proven that Terpenes synthesise via mevalonic pathway from pre- processor of Acetyl CoA, while Phenolic compounds are aromatic substances formed via Shikimic acid pathway or mevalonic pathway and considerably the Nitrogen containing secondary metabolites such as Alkaloids synthesise primarily from Aliphatic amino acids derived from Tricarboxilic acid cycle pathway or Aromatic acids derived from Shikimic acid pathway. These introduced classes of metabolites have been widely used in pharmaceuticals. This manuscript tries to present information about the expression of some useful secondary metabolites and their fascinated usage in pharmaceutics. Phenolic compounds. Plants biosynthesis of the Phenolic compounds regards to the growth, reproduction, pigmentation, resistance to pathogens, influences of heavy metal- salts or in a general form under influences of biotic and a-biotic stresses. These fabulous
