Deoxymulundocandin--a new echinocandin type antifungal antibiotic.
TLDR
A new echinocandin type antifungal antibiotic, C48H77N7O15, was isolated from the culture filtrate and mycelia of a fungal culture, Aspergillus sydowii, and the structure was established by comparative GC-MS analyses of the derivatized acid hydrolysates of deoxymulundoc andin. Expand
Enantioselective Aldol and Michael Additions of Achiral Enolates in the Presence of Chiral Lithium Amides and Amines
It is now well established that lithium enolates and analogous derivatives generally exist as complex structures held together by noncovalent bonds («supramolecules»). In particular, Li enolatesExpand
Chemical constituents and biological studies of Origanum vulgare Linn.
Bioassay-guided isolation of methanolic extract of the leaves of Origanum vulgare Linn., yielded two protocatechuic acid ester derivatives, origanol A (1) and origanol B (2) along with ursolic acidExpand
Substitution of HMPT by the cyclic urea DMPU as a cosolvent for highly reactive nucleophiles and bases
The cyclic urea DMPU (N, N′-dimethyl-N, N′-propylene urea = 1,3-dimethyl-2-oxo-hexahydropyrimidine) is shown to exhibit the same effects HMPT in oxirane-opening with Li-acetylide, in a WittigExpand
Methylsulfomycin I, a new cyclic peptide antibiotic from a Streptomyces sp. HIL Y-9420704.
TLDR
The in vitro activity of methylsulfomycin I against a wide range of Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-, and teicoplanin-resistant strains, is described. Expand
