Aims: The aim was to study the elimination and Phase 2 biotransformation of 4'-hydroxy-4-methoxychalcone ( 1 ) its bis-Mannich analog in small intestine rat. Background: Earlier studies indicated that chalcones are promising starting points for drug design. Aminomethylation drugs is considered improve their delivery into human body. Objectives: To set up validated HPLC-UV methods quantitate inv...

Practical synthesis and biological activities of 4-hydroxy-3-methoxy-2-propene derivatives are described. The novel chalcone derivatives were prepared by acid catalysed one-step condensation of 1,3- or 1,4-diacetylbenzene and 1,3,5-triacetylbenzene with 4-hydroxy-3-methoxybenzaldehyde. They were then evaluated for free radical scavenging activity, suppression of lipopolysaccharides (LPS)-induce...

The asymmetric unit of the title compound, C(10)H(9)NO, contains two independent mol-ecules which are linked by a pair of O-H⋯N hydrogen bonds into a hydrogen-bonded dimer.

the series of 3-(substitutedphenyl)-n-(4h-1,2,4-triazol-4-yl)acrylamide compounds were prepared byreaction of 4-amino-1,2,4-triazole with acetyl chloride followed by claisen-schmidt condensation reactionwith different aromatic aldehydes. the structures of new compounds were confirmed by ir, 1h-nmr and13c-nmr spectral data. anti-bacterial and anti-fungal activities were evaluated and compared wi...

The effect of flavonoids isolated from arbuscular mycorrhizal (AM) colonized and noncolonized clover roots on the number of entry points and percentage of root colonization of tomato (Lycopersicum esculentum L.) by Gigaspora rosea, Gi margarita, Glomus mosseae and G. intrarradices symbionts was determined. With fungi of both genera, a correlation between the number of entry points and the perce...
