 AB    During the reisolation of the trimeric naphthoquinone derivative
       conocurvone [1] from an extract of the Australian shrub Conospermum
       incurvum, six monomeric naphthoquinones were isolated. These include
       three novel 1,4-naphthoquinone derivatives:
       3-methyl-14,15-dihydro-15-hydroxyteretifolione B [3],
       3-methyl-14,15-dihydro-15-hydroxyteretifolione B methyl ether [4], and
       2,3-dimethyl-6-hydroxy-7-methoxy-1,4-naphthoquinone [5]. In addition,
       the previously reported compounds 3-methylteretifolione B [6],
       3-methylteretifolione B methyl ether [7], and
       8-geranyl-2,7-dihydroxy-3-methyl-1,4-naphthoquinone [8] were isolated
       and identified. The structures of the novel 1,4-naphthoquinones were
       elucidated by spectral methods. While conocurvone [1] is a potent
       inhibitor of HIV-1-induced cell killing, all of the monomeric
       naphthoquinone derivatives were inactive against HIV-1.
