Embodiment 1

[0046] Embodiment 1: 2,8-diaryl (amino) Chaoger base derivatives of the present invention include: 2,8-triarylpyridine (tripyridine) Chaoger base (TB) derivatives, 2,8- Diaryl Chaoger base (TB) derivatives and 2-aryl-8-amino Chaoger base (TB) derivatives;

[0047] 1. The synthetic method of 2,8-triarylpyridine (tripyridine) Chaoger base derivative, the substance structure of "2,8-triarylpyridine (tripyridine) Chaoger base (TB) derivative" is as follows:

[0048]

[0049] The method comprises the steps of:

[0050]

[0051] (a) trifluoroacetic acid, -15°C-0°C, 6d; (b) n-butyl lithium, trimethyl borate, -78°C-r.t.; (c) tetrakistriphenylphosphine palladium, potassium carbonate, toluene, 110°C;

[0052] 1) Synthesis of compound 1a, i.e. 2,8-dibromochauger base:

[0053] Add 60mmol of p-bromoaniline and 120mmol of paraformaldehyde into a 250mL dry three-neck round bottom flask at -15°C, and slowly drop 120mL of trifluoroacetic acid into it with a constant pressure funnel u...

Abstract

The invention discloses a synthesis method of 2,8-diaryl(amino) Troger's base derivatives, belonging to the synthesis method of the Troger's base derivatives. The 2,8-diaryl(amino) Troger's base derivatives comprise 2(8)-triarylpyridyl (tripyridyl) Troger's base (TB) derivative, 2,8-diaryl Troger's base (TB) derivative and 2-aryl-8-amino Troger's base (TB) derivative; the synthesis method adopts Suzuki reaction to respectively introduce triarylpyridyl, tripyridyl, phenyl, phenanthryl or anthryl fragment into the TB skeleton, and Ullmann reaction to introduce carbazole, diphenylamine or phenothiazine into the TB skeleton, to obtain the new 2,8-diaryl(amino) Troger's base (TB) derivatives. Four products with excellent human liver cancer HepG2 cell activity resistance are selected from all products with human liver cancer HepG2 cell activity resistance. The method introduces phenothiazine, carbazole and other fragments with physiological activities into the TB skeleton, to design and synthesize 2,8-diaryl(amino) Troger's base derivatives for the first time, so as to screen compounds with liver cancer activity resistance through the combination of both.

Description

technical field [0001] The present invention relates to the technical field of chemical synthesis, in particular to a synthesis method of a 2,8-diaryl (amino) Chaoger base derivative and its anti-human liver cancer HepG2 activity. Background technique [0002] Liver cancer is one of the most common malignant tumors. Current treatment methods include surgery, radiation therapy, and drug therapy. Surgical treatment can delay or even stop the proliferation of liver cancer cells, but it will cause serious secondary damage to the patient. Some patients died of wound infections after surgery to remove the cancerous lesions of their livers, as their bodies were already overwhelmed. Chemical drugs can reduce the patient's pain and prolong the survival time, so it is an ideal important means and treatment method. Therefore, in recent years, the research and development of new drugs against liver cancer has become a multi-disciplinary field of pharmacy, chemistry, pharmacology, and...
