- Synthesis and biological activity of some novel substituted quinazoline derivatives
-
A new series of 4-N-(substituted benzyl)-2-phenyl-N-propylquinazolines were synthesized. The structures of the synthesized compounds were confirmed by IR, 1H NMR, 13C NMR and mass spectral analysis. All the synthesized compounds were screened for their analgesic and anti-inflammatory activity. Among the synthesized compounds 5c, 5h and 5o exhibited significant analgesic activity at 60 and 90 minutes reading, while compounds 5g, 5k and 5l exhibited significant anti-inflammatory activity at 3rd and 4th hr reading.

- Preparation of benzolactams by Pd(OAC)2-catalyzed direct aromatic carbonylation
-
We developed a new method for Pd(II)-catalyzed direct aromatic carbonylation in a phosphine-free catalytic system using Pd(OAc)2 and Cu(OAc)2 in an atmosphere of CO gas containing air. The carbonylation proceeded with ortho-palladation, inducing a remarkable site selectivity to afford a variety of five- or six-membered benzolactams from secondary ω-arylalkylamines, such as N-alkylbenzylamines or N-alkylphenethylamines.

- Benzylamines: Synthesis and evaluation of antimycobacterial properties
-
The synthesis of benzylamines with various N-alkyl chains and substituents in the aromatic system as well as their evaluation on Mycobacterium tuberculosis H 37 Ra are described. The most active compounds in this test, N-methyl-3-chlorobenzylamine (MIC 10.2 μg/mL), N-methyl-3,5-dichlorobenzylamine (93, MIC 10.2 μg/mL), and N-butyl-3,5-difluorobenzylamine (MIC 6.4 μg/mL), also exhibited a marked inhibitory effect on Mycobacterium marinum and Mycobacterium lufu used for the determination of antileprotic properties. The combination of 93 with aminosalicylic acid, streptomycin, or dapsone exert marked supra-additive effects on M. tuberculosis H 37 Ra.
