Room Temperature Synthesis and Antibacterial Activity of New Sulfonamides Containing N,N-Diethyl-Substituted Amido Moieties
Sulfonamide drugs which have brought about an antibiotic revolution in medicine are associated with a wide range of biological activities. We have synthesized a series of α-tolylsulfonamide, 1-11 and their substituted N,N-diethyl-2-(phenylmethylsulfonamido) alkanamide derivatives, 12-22 in improved and excellent yields in aqueous medium at room temperature through highly economical synthetic ro...
متن کاملGreen Chemical Synthesis and Biological Evaluation of Novel N-substituted Rhodanine Derivatives as Potential Antifungal Agents
Background and purpose: In medicinal chemistry, molecules containing rhodanine(2-thiazolidine-4-one) ring as a magic multifunctional privileged structural and functional scaffold show a broad range of potent pharmacological properties containing anti-microbial, antiviral, anti-diabetic, and anti-convulsant effects. Evidence suggests that the activity of the rhodanine derivative correlates with ...
متن کاملSYNTHESES, ANTIFUNGAL AND ANTIBACTERIAL ACTIVITIES OF SUBSTITUTED 1,2, CTRIMOLES
The reaction of readily available 1 -methyl-4-nitropyrrole-2- carboxylic acid (1) with thionyl chloride afforded the corresponding acyl chloride 2. The reaction of compound 2 with thiosemicarbazides yielded 1-(1 -methyl-4-nitrop yrrole-2-carbony1)- thiosemicarbazides (3) which cyclized in basic medium to 5-(1-methyl-4-nitropyrrole- 2-y1)-2,4-dihydro-3H- l,2,4-triazole-3- thione 4. Alkylatio...
متن کاملAntibacterial, antifungal and cytotoxic isoquinoline alkaloids from Litsea cubeba.
Five novel isoquinoline alkaloids (+)-N-(methoxylcarbonyl)-N-nordicentrin (1), (+)-N-(methoxylcarbonyl)-N-norpredicentrine (2), (+)-N-(methoxylcarbonyl)-N-norbulbodione (3), and (+)-N-(methoxylcarbonyl)-N-norisocorydione (4), and (+)-8-methoxyisolaurenine-N- oxide (5) were isolated, together with one known compound, (+)-N-(methoxylcarbonyl)- N-norglaucine (6), from a 70% EtOH extract of the bar...
متن کاملSynthesis and antibacterial and antifungal activities of N-(tetra-O-acetyl-β-d-glucopyranosyl)thiosemicarbazones of substituted 4-formylsydnones
BACKGROUND Sydnone is a heterocycle that exhibits remarkable pharmacological activities, including antimicrobial, anti-inflammatory, analgesic, antipyretic and antioxidant activities. Thiosemicarbazones are of compounds that contain the -NHCSNHN=C< linkage group and are considerable interest because they exhibit important chemical properties and potentially beneficial biological activities. Sim...
