Abstract

The invention discloses a ferrocenyl amide derivative containing a pyrimidine ring and a preparation method and application thereof. The structure of the ferrocenyl amides derivative containing the pyrimidine ring is as shown in a general formula (1) or a general formula (2) as shown in the specification, wherein R is selected from 4-chlorine, 4-methoxyl, 4-methyl, 3-chlorine, 3,5-dimethoxy, 3,5-dichlorine, 4-ethyl, 4-chlorine, 4-bromine, 3-bromine, 3-methyl, 4-trifloromethoxyl or hydrogen. The ferrocenyl amide derivative containing the pyrimidine ring has an obvious growth inhibiting effect on mice skin melanoma cells (B16-F10) and human lung cancer cell strains (A549), and can be used for preparing antineoplastic pharmaceuticals.

Description

[0001] 1. Technical field [0002] The invention relates to a ferrocene derivative, in particular to a ferrocene amide derivative containing a pyrimidine ring, a preparation method and application thereof. [0003] 2. Background technology [0004] Ferrocene is an orange-yellow prism or powder crystal, chemically named cyclopentadienyl iron, which is composed of two cyclopentadiene and a ferrous ion. An iron atom is sandwiched between the two cyclocene rings. It is a typical type II complex with a sandwich structure. It has aromaticity and a very stable structure. It will not decompose below 470°C. Its chemical properties are similar to those of aromatic compounds, it is not easy to undergo reduction reaction, and it is prone to electrophilic substitution reaction. The structure determines the properties. The particularity of the structure of ferrocene determines that ferrocene and its derivatives have various biological activities, including anti-tumor, anti-anemia, anti-mala...
