Novel derivatives of 2-amino benzothiazoles 4(a-j) have been synthesized and tested for their antitumor activity using National Cancer Institute (NCI) disease oriented antitumor screen protocol against nine panel of cancer cell lines. Among the synthesized compounds, two compounds were granted NSC code and screened at National Cancer Institute (NCI)-USA for anticancer activity at a single high dose (10(-5) M) and five dose in full NCI 60 cell panel. Among the selected compounds,7-chloro-N-(2,6-dichlorophenyl) benzo[d]thiazol-2-amine (4i) with GI(50) values of 7.18 x 10(-8) M against Non-Small Cell HOP-92 Lung Cancer cell line proved to be the most active members in this study. Virtual screening was carried out through docking the designed compounds into the ATP binding site of epidermal growth factor receptor (EGFR) to predict if these compounds have analogous binding mode to the EGFR inhibitors.

Thiourea derivatives (1–38) were synthesized and evaluated for their urease inhibition potential. The synthetic compounds showed a varying degree of in vitro urease inhibition with IC50 values 5.53 ± 0.02–91.50 ± 0.08 μM, most of which are superior to the standard thiourea (IC50 = 21.00 ± 0.11 μM). In order to ensure the mode of inhibition of these compounds, the kinetic study of the most active compounds
α-Chymotrypsin inhibitors of thiourea class are reported that could be potent inhibitors of proteases, elastases, proteasomes, NS3 and NS4 serine protease of hepatitis C virus, dengue virus, etc. Compounds

which are belong to thiourea class, showed good inhibition. Their kinetics study and cytotoxicity profiles showed all type of inhibition except uncompetitive-type inhibition and no cytotoxicity except few compounds. Competitive type of inhibitors could inhibit other α-chymotrypsin-like serine proteases, which are therapeutics target.
