In the present study a new Tetrahydro-quinazoline analogues (MB I-V) were synthesized. The newly synthesized compounds were characterized by IR, NMR and C, H, N, S analyses. All newly synthesized compounds were screened for their antibacterial (Pseudomonas aurigenosa Bacillus subtilis and Escherichia coli) studies. The results revealed that all synthesized compounds have a significant biological activity against the tested microorganisms. %K Tetrahydro-Quinazoline %K Antibacterial Activity %K Isophorone %U http://article.sapub.org/10.5923.j.ajoc.20120205.03.html
