A highly efficient and milder protocol for the syntheses of novel series of 2-aminothiazoles bearing 5-methylisoxazoline and pyridine-piperazine hybrid molecules has been developed. The target compounds 13a-e were screened for their in vitro cytotoxicity activity against various tumor cell lines including MCF-7 (human breast adenocarcinoma), HCT-116 (colorectal carcinoma), Jurkat (human T-cell leukemia) and THP-1 (human acute monocytic leukemia). The bioactive assay showed that the most of the new compounds exhibited promising results in comparison with the parental Sunitinib. The synthesized compounds could well be used in the future as lead anticancer drugs in drug development studies. The synthesized compounds were fully characterized by IR,1 H NMR,13 C NMR, elemental analysis and mass spectral data.

A synthetic methodology for the specific conversion of primary aromatic amines into their N-monomethyl derivatives under very mild conditions is presented. Anilines are treated with 4-nitrobenzenesulfonyl (nosyl) chloride to generate the corresponding sulfonamides 2 in high yields. The subsequent N-methylation reaction of the sulfonamides 2 with a solution of diazomethane is rapid and quantitative. Removal of the nosyl protecting group is readily carried out using the reagent system mercaptoacetic acid/1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) affording the N-monomethylated aromatic amines 4. The procedure is convenient, efficient, and gives rise to the N-monomethyl-anilines exclusively.

Moderate cyclic GMP phosphodiesterase (cGMP-PDE, PDE V) inhibitor 2- phenyl-4-anilino-quinazoline (1) was identified utilizing MultiCASE assisted drug design (MCADD) technology. Modification of compound 1 was conducted at the 2-, 4-, and 6-positions of the quinazoline ring for enhancement of cGMP- PDE inhibitory activity. The 6-substituted 2-(imidazol-1-yl)-quinazolines are 1000 times more potent in in vitro PDE V enzyme assay than the well-known inhibitor zaprinast. The 6-substituted derivatives of 2-(3- pyridyl)quinazoline 84 and 2-(imidazol-1-yl)quinazoline 86 exhibited more than 1000-fold selectivity for PDE V over the other four PDE isozymes. In addition, cGMP-PDE inhibitors 64, 65, and 73 were found to have an additional property of thromboxane synthesis inhibitory activity.
