The invention discloses a glycyrrhetinic acid-
hydrogen sulfide donor
reagent derivative, and a synthetic method and an application thereof. The synthetic method of the derivative comprises the following steps: carrying out a reaction on glycyrrhetinic acid, alpha,
omega-dibromoalkane and an alkali in an aprotic polar
solvent to obtain a compound 1; and carrying out a reaction on the compound 1, a
hydrogen sulfide donor and the alkali in the aprotic polar
solvent to obtain a crude target product, wherein the reactions are carried out under heating or non-heating conditions. Most compounds in the synthesized derivative have certain inhibition activity to a chronic marrow
leukemia cell K562, and are hopeful to be used in the preparation of corresponding antitumor medicines and chronic marrow
leukemia cell treatment medicines. The synthesized derivative has a structure represented by general formula (I) shown in the description; and in the general formula (I), n is 2-8, and R is one of three formulas shown in the description.
