X-ray Diffraction, Electronic Circular Dichroism, and Quantum Mechanics (TD-DFT) Investigations on 4 Dehydroxyaltersolanol A, a Secondary Metabolite from Endophytic Fungus Nigrospora oryzae [PDF]
Background and objectives: A tetrahydro anthraquinone derivative, 4-dehydroxyaltersolanol A, has been obtained from Nigrospora oryzae, which was isolated from Uncaria borneensis Havil as an endophytic fungus.

Ortho‐Quinone Methide Driven Synthesis of New O,N‐ or N,N‐Heterocycles
To synthesize functionalized Mannich bases that can serve two different types of ortho‐quinone methide (o‐QM) intermediates, 2‐naphthol and 6‐hydroxyquinoline were reacted with salicylic aldehyde in the presence of morpholine.

Focus on chirality of HIV-1 non-nucleoside reverse transcriptase inhibitors [PDF]
Chiral HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) are of great interest since one enantiomer is often more potent than the corresponding counterpart against the HIV-1 wild type (WT) and the HIV-1 drug resistant mutant strains.
