The application belongs to the field of pharmaceutical chemistry, and particularly relates to an oxaliplatin prodrug and a preparation and application thereof. The structure of the oxaliplatin prodrug is specifically shown as formula (I). The oxaliplatin prodrug can be dissolved in physiological saline to form a nano preparation, which not only solves the instability problem of oxaliplatin in physiological saline, but also reduces the systemic toxicity of oxaliplatin, and achieves the effect of reducing toxicity and increasing efficiency. The oxaliplatin prodrug can be reduced in a reducing environment in tumor cells to release oxaliplatin to kill tumor cells, and achieve an antitumor effect superior to that of oxaliplatin. The synthesis method of the oxaliplatin prodrug and the preparation method of the nano preparation are simple and easy to implement, which are conducive to solving the poor stability problem of oxaliplatin in physiological saline, and are expected to realize clinical transformation.

The invention relates to the technical field of compound preparation, and provides a preparation method of a pentazocine intermediate isomer impurity, which comprises the following steps: reacting benzylamine with 2-(4-methoxyphenyl)-2-oxoacetaldehyde to obtain an imine intermediate; the imine intermediate and 2, 3-dimethyl-1, 3-butadiene are subjected to a cyclization reaction, and a ketone carbonyl intermediate is obtained; and reducing the keto-carbonyl intermediate with hydrazine hydrate to obtain the pentazocine intermediate isomer impurity. The process steps are simple and convenient, the yield is high, the product purity reaches 98.8%, and the blank of an undisclosed directional preparation process of the impurity is filled; compared with a traditional mode of separating and obtaining impurities from a liquid phase prepared from a reaction solution, the method has the advantages that the efficiency is higher, the cost is lower, the yield is stable, and the prepared impurities can be used as a pentazocine quality control reference substance and are more suitable for the quality control requirement of industrial production.

This invention discloses a branched functional polypeptide, a photoelectrochemical biosensor for detecting cardiac troponin I, its preparation method, and its applications, belonging to the field of biosensor technology. The branched functional polypeptide provided by this invention includes a main chain and branched chains. The main chain is a recognition polypeptide capable of recognizing the target analyte, and the branched chains are antifouling polypeptides capable of resisting biocontamination. The photoelectrochemical biosensor for detecting cardiac troponin I provided by this invention includes a ZIS / PDA photoelectrode. The branched functional polypeptide is directly anchored to the ZIS / PDA photoelectrode. The detection of cardiac troponin I is achieved by utilizing the significant steric hindrance effect after cardiac troponin I specifically binds to the main chain, which hinders charge transfer in the photoelectrochemical biosensor and causes a change in the photocurrent signal. This invention improves both the specificity and sensitivity of target analyte detection, as well as the accuracy of detection.
