Problems solved by technology

[0007] Poor absorption, distribution, metabolism and / or excretion (ADME) properties are known to be a major reason for failure of many drug candidates in clinical trials
Many currently marketed drugs also limit their application range due to poor ADME properties
The rapid metabolism of drugs will cause many drugs that can treat diseases with high efficiency to be eliminated from the body too quickly, making it difficult to become a drug
Although frequent or high-dose medication may solve the problem of rapid drug clearance, this method will bring problems such as poor patient compliance, side effects caused by high-dose medication, and increased treatment costs
In addition, rapidly metabolizing drugs may also expose patients to undesirable toxic or reactive metabolites

preparation example Construction

[0085] The preparation of the compounds of the present invention may involve the protection and deprotection of various chemical groups. The need for protection and deprotection and selection of appropriate protecting groups can be readily determined by those skilled in the art. The chemistry of protecting groups can be found in, eg, Wuts and Greene, Protective Groups in Organic Synthesis, 4th Edition, John Wiley & Sons: New Jersey, (2006), which is incorporated herein by reference in its entirety.

[0086] The reaction can be monitored according to any suitable method known in the art. For example, spectroscopic means such as nuclear magnetic resonance (NMR) spectroscopy (e.g. 1 H or 13 C), infrared (IR) spectroscopy, spectrophotometry (e.g., UV-visible), mass spectroscopy (MS)) or by chromatographic methods such as high performance liquid chromatography (HPLC) or thin layer chromatography (TLC) Product formation was monitored.

Description

technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to N-benzenesulfonylbenzamide compounds with excellent inhibitory effect on Bcl-2 protein, pharmaceutical compositions containing them, and their preparation methods and applications. Background technique [0002] Designing and synthesizing new anti-tumor drugs against tumor-specific targets has become the focus of targeted anti-tumor therapy. Recent studies have shown that the mechanism of apoptosis (programmed death) is involved in the occurrence, development and regression of tumors. Apoptosis is highly conserved, and similar molecular mechanisms of apoptosis exist in different species of organisms. The known apoptosis signaling pathways include two pathways, endogenous and exogenous. The mitochondrial apoptotic pathway is an endogenous pathway, and the apoptosis pathway mediated by death receptors is an exogenous pathway. In the endogenous pathway of apoptosis, the...
