Plumbagin is a yellow-orange pigment isolated from Plumbagin and other plant species. Research into Plumbagin dates back to the early 1800s, with its synthesis reported in 1936. Plumbagin has a broad...
Piliformic Acid is produced by fungi including Xylaria sp. Piliformic acid has mild inhibitory activity against Propionobacterium acnes, inhibiting the P. acnes-induced pro-inflammatory cytokines...
Pikromycin was the first macrolide antibiotic, isolated in 1951 by the German researchers Brockmann and co-workers from Streptomyces sp. Its structure as a 14-membered lactone linked to D-desosamine...
Phomopsinamine is a potent mycotoxin produced by the fungus, Phomopsis leptostromiformis. Phomopsinamine is formed by hydrolysis of the dicarboxylic acid of phomopsin A. The phomopsins cause...
Pepstatin A, a pentapeptide isolated from Streptomyces sp. is a strong inhibitor of aspartyl proteases such as pepsin, cathepsin D, and renin. Pepstatin is active against HIV-1 and Plasmodium...
Pentalenic acid has been isolated from many Streptomyces sp. as a co-metabolite of the sesquiterpenoid antibiotic pentalenolactone and related natural products. Pentalenic acid is a shunt metabolite...
Penipurdin A was first reported as an orange-red anthraquinone produced by soil-derived Penicillium purpurogenum by Li and co-workers from the Key Laboratory of Plant Resources Conservation and...
The palmarumycins are fungal metabolites isolated from Coniothyrium and Sphaeropsidales sp. with antifungal, antibacterial, antitumor and herbicidal properties. Palmarumycin C3 is a yellow-green...
