Synthesis and Biological Evaluation of Simplified Ansellone Analogues with Lipophilic Side Chains as HIV-Latency-Reversing Agents.

Structurally simplified analogues of ansellone A, in which the decalin skeleton is replaced with a lipophilic chain, were prepared and their HIV latency-reversing activities biologically evaluated. In particular, two analogues bearing ether and alkenyl side chains, respectively, showed comparable activities to that of ansellone A. Each of the simplified compounds was easily synthesised using Prins cyclisation chemistry.
