Embodiment Construction

[0018] Synthetic Irreversible Inhibitors of GlxI

[0019] The synthetic pathways of S-(bromoacetamidoalanylmethyl)glutathione (BPSG) and S-(bromoacetamidobutanylmethyl)glutathione (BBSG) are as follows:

[0020]

[0021] Dibromoacetyl(1,3)propylenediamine

[0022] Put 50 milliliters of chloroform and 1,3-propanediamine (13mmol) in the flask of 100 milliliters, then put into ice bath and wait for cooling, slowly drop bromoacetyl chloride (1.03g, 26mmol) under stirring condition , Continue to stir for half an hour after dripping. The solvent was evaporated to dryness with a rotary evaporator under reduced pressure to obtain a light brown crude product. Yield: 90%. 1 H NMR 300MHz (CDCl 3 , TMS) δ3.80 (4H, s, -C(O)CH 2 Br), 3.25 (4H, t, J=6.25Hz, -NHCH 2 CH 2 -), 1.85 (2H, p, J=6.25Hz, -NHCH 2 CH 2 -).ESI MS: (M(Br 79 )+H + ) 314.93. Dibromoacetyl (1,4) butanediamine

[0023] The synthetic pathway of this compound is roughly the same as that of dibromoacetyl (1,3) p...

Abstract

The invention belongs to the technical field of medicaments, and discloses anti-tumor medicaments of S-(bromo-acetamido-alanyl-methyl) glutathione and S-(bromo-acetamido-butaminoacyl-methyl) glutathione. The compound reacts with aldoketomutase I in a covalent bond mode so that the aldoketomutase I losses the activity irreversibly. The compound has good development and application prospects in theaspects of medicaments for treating the malignant tumors of prostate cancer, lung cancer, intestinal cancer, testicular cancer, leukemia, mammary cancer, skin cancer and the like.

Description

technical field [0001] Many drugs currently used clinically or under development rely on direct or indirect inhibition of DNA and / or protein to achieve the purpose of attacking tumor cells. Therefore, rapidly dividing normal cells, such as the intestinal epithelium and bone marrow, are also adversely affected to produce strong side effects. This technology invention describes a unique small molecule anti-tumor compound, which does not depend on cell division and differentiation, but acts on the glyoxalase system to cause programmed death of tumor cells, which can greatly reduce toxic and side effects. [0002] The human body's sugar metabolism inevitably produces a toxic compound called methylglyoxal, which can cause programmed cell death. During the long-term evolution process, the human body has developed a system called glyoxalase, which is composed of glyoxalase I (glyoxalase I, GlxI for short) and glyoxalase II (glyoxalase II, GlxII for short). Detoxification effect of ...
