Taccalonolide AJ, a microtubule stabilizer with persistent antitumor effects, is less effective systemically due to a short in vivo half-life.

Taccalonolide AJ is a natural product that has been found in the liver of humans and other species. It has been shown to have anticancer activity, which may be due to its ability to inhibit cancer cell growth. Taccalonolide AJ has been found to inhibit the formation of disulfide bonds between two cysteine molecules, which are important for protein folding. The drug also inhibits the growth of tumor cells in culture at lower concentrations than those necessary for inhibition of cell growth in human hepatomas. This inhibition is thought to be due to the compound’s ability to act as a nucleophile and attack sulfhydryl groups on proteins.
