In 1990, Moore et al. reported the isolation of S-cyano-h-methoxy-ll-methyl-indolo[2,3-fl]carbazole (357), along with a minor component, 6-cyano-5-methoxy-indolo[2,3-fl]carbazole (358), from the blue-green alga Nostoc sphaericum EX-5-1 (340). These were the first, naturally occurring, indolo[2,3-fl]carbazole alkaloids with a simple indolo[2,3-fl]carbazole (356) framework (Scheme 2.92). These alkaloids are moderately active against herpes simplex virus type 2 and are weakly cytotoxic against murine and human cancer cell lines (340). [Pg.144]

A 6-cyano-5-methoxy-12-methylindolo[2,3-a]carbazole and 6-cyano-5-methoxyindolo[3-a]carbazole were isolated from the blue-green alga Nostoc sphaericum [95]. These compounds are active against HSV-1. Larsen ct al. [96] isolated three new chlorine-containing P-carbolines, bauerines A-C, from the blue-green alga Dichothrix baueriana. These alkaloids show activity against HSV-2. [Pg.115]

Borophycin (15) was found to display appreciable c5dotoxicity against LoVo cells (MIC 0.066 pg/mL) and KB cells (MIC 3.3 pg/mL). It was isolated from the lipophilic extract of a marine strain of the blue-green alga Nostoc linckia [53]. Borophycin is made up of two identical halves with an overall structure reminiscent of other boron-containing antibiotics. The C3 starter unit for the biosynthesis of 15 is derived from acetate and methionine, but not propionate. [Pg.850]

The boron-containing polyketide borophycin (21) has been isolated and characterized by Moore and Clardy [43] from the blue-green alga Nostoc linckia. The structure of this new polyketide is closely related to that of the ionophoric antibiotics boromycin (22) isolated from a terrestrial strain of Streptomyces antibioticus, and aplasmomycin (23) from a marine strain... [Pg.303]
