Previous studies have indicated that the δ-carboline ring system derived from the natural product cryptolepine may represent a pharmacophore for anti-infective activity. The design and synthesis of a small library of substituted δ-carbolines and the evaluation of their antifungal and antibacterial activities is reported. An evaluation of the antibacterial activity of a previously reported library of ring-opened analogs was also conducted to provide an opportunity to test the hypothesis that both group of compounds may have the same biol. target. Results indicate that against a selected group of fungal pathogens, substituted δ-carbolinium analogs displayed higher potency and several fold lower cytotoxicity than cryptolepine the parent natural product. Both the δ-carbolinium compounds and their ring-opened analogs, exhibited equally high antibacterial activity against the selected pathogens and especially against the gram pos. bacteria evaluated. This study involved multiple reactions and reactants, such as N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2Quality Control of N-(4-Methoxyphenyl)pyridin-3-amine).
N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
