A facile and simple one‐pot procedure for the synthesis of various aralkyl/alkylthio‐3,5‐dimethyl‐1H‐pyrazolyl‐4H‐1,2,4‐triazol‐4‐amines has been described via a multicomponent reaction of 4‐amino‐5‐hydrazinyl‐4H‐1,2,4‐triazole‐3‐thiol, acetylacetone, and various aryl/alkyl halides in good yields. All the newly synthesized compounds were characterized by using analytical and spectral studies. Our in silico studies confirmed that 4e, 4f, 4g, and 4j have the best inhibition activity among the synthesized compounds with a high selective index against the Tubulin protein and showed best interactions with receptor structure. The present study provides a novel series of compounds with a promising inhibitor to prevent on Tubulin protein.
