Four isomers of 3,28-di-O-(dimethylsuccinyl)-betulin were prepared and evaluated for anti-HIV activity against HIV-1 replication in H9 lymphocyte cells. 3-O-(3',3'-Dimethylsuccinyl)-28-O-(2", 2"-dimethvlsuccinyl)-betulin (11) was the most potent anti-HIV compound with an EC5, value of 0.00087 microM and a TI value of 42,400.
