The invention discloses a method for preparing target
antineoplastic drug chlorinated nitidine compound, products thereof and an injection containing the products. The method for preparing the target
antineoplastic drug chlorinated nitidine compound comprises the steps of pre-treating the chlorinated nitidine to acquire
carboxylic acid-modified chlorinated nitidine, then using amphiphilic polymers to implement non-covalent functionalized modification on the outer wall of a single-wall carbon
nano tube that is
cut to be 20-500 nm long, and
coupling the
carboxylic acid-modified chlorinated nitidine with the single-wall carbon
nano tube after the non-covalent functionalized modification by means of esterification and amidation reactions to acquire the compound. The preparation method of the compound is simple, the
solubility of the resulting products can reach 5.0mg / mL, and the antineoplastic target is strong, thus favorably
settling the problems of low
solubility and strong
toxicity of the chlorinated nitidine; in addition the invention can be applied clinically as a substitute for the chlorinated nitidine and provides a new water-soluble compound for the
clinical trial of the chlorinated nitidine.
