Malic acid accumulation by Aspergillus flavus
SummaryThe accumulation and excretion of l-malic acid, and to a lesser extent succinic and fumaric acids, by Aspergillus flavus occurs under aerobic conditions in a medium containing a high glucoseExpand

Oxygen atom transfer reactions from isolated (oxo)manganese(V) corroles to sulfides.
A series of five free-base corroles were metalated and brominated to form 10 manganese(III) corroles. Two of the free-base corroles and six manganese(III) corroles were analyzed by X-rayExpand

The cytosolic pathway of l-malic acid synthesis in Saccharomyces cerevisiae: the role of fumarase
Saccharomyces cerevisiae accumulates l-malic acid but only minute amounts of fumaric acid. A 13C-nuclear magnetic resonance study following the label from glucose to l-malic acid indicates that theExpand

Novaxenicins A–D and xeniolides I–K, seven new diterpenes from the soft coral Xenia novaebrittanniae
Abstract Seven new diterpenes, novaxenicins A–D (1–4) and xeniolides I–K (5–7), have been isolated from the Kenyan soft coral Xenia novaebrittanniae. The structures and relative stereochemistry ofExpand

Porphyrin framework solids. Synthesis and structure of hybrid coordination polymers of tetra(carboxyphenyl)porphyrins and lanthanide-bridging ions.
New types of porphyrin-based framework solids were constructed by reacting meso-tetra(3-carboxyphenyl)porphyrin and meso-tetra(4-carboxyphenyl)metalloporphyrins with common salts of lanthanide metalExpand

One-step conversions of a simple corrole into chiral and amphiphilic derivatives
Abstract The reactions of phosgene with 5,10,15-tris(pentafluorophenyl)corrole and its gallium(III) complex lead to a novel chiral macrocycle and an amphiphilic corrole, respectively. Both types ofExpand

Asmarines A-C; Three novel cytotoxic metabolites from the marine sponge Raspailia sp.
Abstract Three novel nitrogen-containing metabolites, asmarines A-C (1 – 3) together with two known diterpenes, zaatirin and chelodane were isolated from the Red Sea sponge Raspailia sp. collected inExpand

Antheliatin and zahavins A and B, three new cytotoxic xenicane diterpenes from two soft corals
Antheliatin [1], zahavin A [2], and zahavin B [3], three novel xenicane diterpenoids, have been isolated from two Indo-Pacific soft corals, Anthelia glauca and Alcyonium aureum. The two speciesExpand
