Core Tip |
We developed a novel gallstone-dissolving agent, named tert-amyl ethyl ether (TAEE), an methyl-tertiary butyl ether (MTBE) analogue, with a relatively higher boiling point (102 °C). The in vitro results demonstrated a 24 h TAEE-dissolubility of 76.7%, 56.5% and 38.75% for cholesterol, mixed, and pigmented gallstones, respectively, which represented a 1.2-, 1.4-, and 1.3-fold increase in dissolubility compared to that of MTBE. In the in vivo experiment, TAEE showed a 1.4- and 1.9-fold higher dissolubility for cholesterol and pigmented gallstones than MTBE. As such, TAEE could present an attractive alternative to MTBE if further clinical studies validate its efficacy and safety. |
