Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention and not to limit its scope.
Currently, chemical kinetic Therapy (CDT) based on Fenton (Fenton) reaction has attracted more and more attention as an emerging typical nanocatalysis Therapy, generating Fe2+、Ti3+、Mn2+、Co2+And Cu+The nanomaterial of (a) is a typical Fenton or Fenton-like reagent, which mainly utilizes endogenous chemical substances (such as H) excessively generated under inflammatory conditions in the slightly acidic TME of the tumor2O2) ROS such as highly toxic OH are produced to kill cancer cells. The research finds that: cancer cells may evolve multiple reaction pathways in order to combat toxic ROS, either exogenously or produced by the cancer cells' own metabolism. For example, Glutathione (GSH) has antioxidant defense effects that protect cells from free radical oxidative damage, and is expressed in TME in much higher amounts than normal cells (4-fold higher than in normal cells); if GSH is not exhausted in time, the efficacy of ROS-based tumor therapy will be greatly affected; thus, it is exposed to H in endogenous TME2O2Insufficient reaction kinetics and levels to sustain sustained ROS induction and antioxidant defenseThe influence of the mechanism, the antitumor effect of the single novel therapy has certain limitation. H is adjusted by designing a high-performance Fenton catalyst and simultaneously applying different internal and external strategies2O2The reaction parameters such as concentration, tumor part reaction temperature and the like can improve the dynamics of the Fenton reaction, enhance the Fenton reaction to the maximum extent and be better used for treating tumors, but the reaction parameters are not well realized at present.
In recent years, gas therapy, which is a treatment using a specific gas to suppress tumors, has become a novel effective treatment with few side effects. To date, three major gas molecules have been studied, including carbon monoxide (CO), carbon monoxide (NO), and hydrogen sulfide (H)2S)。H2S is an endogenous gas signal molecule present in the body of a mammal and plays an important role in various physiological and pathophysiological processes. Notably, H2S naturally has fewer side effects on healthy cells due to its endogenous nature associated with multiple metabolic pathways. It is reported that H2The precursors of S are mainly organic polysulfides, such as allicin, which is unstable under physiological conditions and rapidly converts to alkyl sulfides, such as diallyl disulfide (DADS), diallyl trisulfide (DATS) and diallyl sulfide (DAS); these transformation products are active ingredients that inhibit bacterial growth; however, many organosulfur compounds are volatile, produce an unpleasant odor and are poorly water soluble, further limiting their widespread biological and clinical medical use. Studies have also found that polysulfides can efficiently produce H via a thiol-polysulfide cleavage mechanism2And S. Notably, TME is richer in thiols than healthy tissue, which naturally confers polysulfide tumor-specific H2And S is released.
