The continuing emergence of antibiotic-resistant microbes highlights the need for identification new chemotypes with antimicrobial activity. One most prolific sources molecules has been systematic screening natural product samples. National Institute Allergy and Infectious Diseases Cancer here report a large screen 326,656 partially purified fractions against panel four microbial pathogens, resulting in >3000 antifungal and/or antibacterial A small sample these active was further chemical...
Pyrrole-containing natural products form a large group of structurally diverse compounds that occur in both terrestrial and marine organisms. In the present study formation trideuteromethylated artifacts pyrrole-containing was investigated, focusing on discorhabdins. Three deuterated discorhabdins, 1, 3, 5, were identified to be isolation procedure caused by presence DMSO-d6 during NMR sample preparation handling. additional semisynthetic derivatives, 7–9, made investigation mechanism...
Lippia species share various pharmacological activities and are used in traditional cooking medicine worldwide. Combined chromatographic techniques such as column chromatography, high-performance liquid countercurrent chromatography led to the purification of two new antifungal phenylpropanoid glycosides, lippiarubelloside A (1) B (2), by bioactivity-directed fractionation an ethanol-soluble extract from rubella, addition known active related compounds forsythoside (3), verbascoside (4),...
Cytotoxic 6-heptyl-5,6-dihydro-2H-pyran-2-ones are chemical markers of Hyptis (Lamiaceae) and responsible for some the therapeutic properties species with relevance to traditional medicine. The present investigation describes isolation known pectinolides A–C (1–3), in addition new I–M (4–8), from two Mexican collections H. pectinata by HPLC. novel biosynthetically related monticolides A (9) B (10) were also isolated high-speed countercurrent chromatography monticola, an endemic Brazilian...
Structural elucidation of specialized metabolites or natural plant products, especially the stereochemical features chiral bioactive metabolites, is most important stage for all investigations in pharmacognosy and phytochemistry. Numerous methods have been established to solve absolute configuration including direct such as X-ray diffraction, chiroptical spectroscopy, stereo-controlled partial total organic synthesis, chemical correlation by simple reactions derivatization, well indirect...
