Description
Double-response low-drug-resistance nitric oxide donor, and preparation method and application thereof Technical Field The invention relates to the technical field of pharmaceutical chemistry, in particular to a dual-response low-drug-resistance nitric oxide donor, and a preparation method and application thereof. Background Nitric Oxide (NO) is an important endogenous gas signal molecule in a human body, and can widely participate in various physiological processes of a living body due to higher biological activity, so that an important regulation effect is exerted. The nitric oxide molecules have important roles in maintaining cardiovascular homeostasis, nerve signal transduction, natural immune response and the like. Recent researches also show that the nitric oxide is closely related to the tumor, and the nitric oxide with a certain concentration has remarkable effects in regulating and controlling tumor drug resistance, hypoxia, apoptosis and the like. Aiming at the problem of low in vivo concentration of endogenous nitric oxide caused by abnormal metabolism under pathological conditions, the research and development of exogenous nitric oxide donor medicaments have been widely focused. The design and synthesis of nitric oxide donor drugs are of great significance in basic research and clinical application. For example, nitric oxide donors such as 5-mononitroisosorbide, nitroglycerin, and dinitrate isosorbide have been used clinically for the treatment of cardiovascular diseases as first-line medications. Under physiological conditions, the nitric oxide donor medicine releases nitric oxide through cell metabolism to exert the physiological effect of nitric oxide, and is one of the leading edge and the hot spot of the research in the biomedical field in recent years. For example, CN107459482A discloses a nitric oxide donor, a preparation and application thereof, which discloses a chemical formula of the following structure,R 2 is H, C-C8 cycloalkyl, or C1-6 alkyl optionally substituted with 1-2 substituents selected from C1-4 alkoxy, -S (O) 2 -OH, and hydroxy, wherein N is attached to the benzene ring of the fluorophore molecule, which compounds are useful as nitric oxide donors for diseases related to hypertension and the like. CN104119295A discloses a phenothiazine nitric oxide donor, a preparation method and application thereof, and a compound structural formula isN=0, 1 or 2;R 1 is hydrogen, halogen, C1-C4 branched or straight chain alkyl, halogenated C1-C4 branched or straight chain alkyl, R 2 is hydrogen, C1-C4 branched or straight chain alkyl. The compound is used as a pharmaceutical composition of active ingredients and can be used as an anti-tumor drug for preparing drugs for treating breast cancer, lung cancer and gastric cancer. Nitric oxide itself is unstable and cannot be used directly in many medical settings. Nitric oxide donor drugs achieve effective transport in vivo by loading nitric oxide and extend the half-life of nitric oxide to some extent. However, most NO donors today are still not stable, and the half-life under physiological conditions is generally varied from seconds to hours, often requiring low temperature storage and transport, which is a great nuisance for storage and biomedical applications of NO donors. On the other hand, the half-life period of nitric oxide in vivo is only 3-6 seconds, and the diffusion radius is only 40-200 mu m, so that the nitric oxide donor is required to be better converted into NO at a focus part to play a role. In addition, many nitric oxide donors can easily induce the organism to generate drug resistance to NO after being used, and the physiological effect of NO is greatly reduced after being re-dosed. This is mainly due to the fact that high levels of reactive oxygen species in the disease microenvironment will convert NO to reactive nitrogen species, which oxidize or nitrify the biological enzymes of the nitric oxide donor drug metabolism, causing its inactivation and the loss of the ability to produce NO. This problem is usually only handled clinically by stopping the patient, which increases the risk of patient-related diseases. Even with such therapies, patients induce greater resistance after several cycles, often requiring longer withdrawal periods with concomitant higher doses, which can increase drug-related toxic side effects. Therefore, the development of the low-drug-resistance nitric oxide donor has important significance in disease treatment and also has wide application prospect. Disclosure of Invention Aiming at the problems of poor stability, short half-life and easy generation of drug resistance of a nitric oxide donor in the prior art, the invention provides a double-response low-drug-resistance nitric oxide donor which has stable performance and long half-life, can be slowly hydrolyzed under the action of esterase of normal tissues, avoids burst release of nitric oxide and reduces the occurrence of drug resistance.
