Polycarpamines

Polycarpamines A-E (137-141) are unusual sulfur-containing antifungal agents from Polycarpa auzata from the Philippines. The structures were elucidated by interpretation of spectral data [148]. Polycarpine (142), a cytotoxic, dimeric, disulfide alkaloid, the corresponding dihydrochloride (143) and two sulfur-containing related monomers (144-145) were isolated from Polycarpa clavata from Western Australia [149]. Polycarpine (142) was also isolated with two monomers (144,146) from P. auraia from Chuuk [150] and later it was synthesised in three steps from p-methoxyphenacyl bromide [151]. [Pg.640]

Adociaquinones A (492) and B (493) and 3-ketoadociaquinone A (494) were obtained from a sponge Adocia sp. collected in Truk Lagoon (398). Compounds 492 and 493 were synthesized from xestoquinone (399) by heating with hypotaurine. Adociaquinone B (493) was mildly cytotoxic. Polycarpamines A-E (495-499) with a rare, sulfur-containing benzenoid... [Pg.111]
