The invention discloses a class of gold (I) Gefitinib derivatives, their preparation methods, and applications. The methods for preparing the gold (I) Gefitinib derivatives comprise the following steps: 1) Dissolve compound I and potassium hydroxide in methanol, and add a gold ligand II to obtain a mixture; 2) Stir the mixture for reaction, and then filter under reduced pressure to obtain a crude product; 3) Purify the crude product to obtain the gold (I) Gefitinib derivatives. One of the gold (I) Gefitinib derivatives has an EGFR/TrxR dual-target anti-lung cancer effect, retaining the stem nucleus structure of Gefitinib, 4-aniline-quinazoline, to ensure its original EGFR targeting inhibition activity, and introducing alkynyl groups with different carbon chain lengths to connect different gold ligands so that it can target both EGFR and TrxR simultaneously, enhancing its anti-lung cancer activity and overcoming the resistance of lung cancer to Gefitinib.
