Thiazole is an important scaffold due to variety of pharmacological properties associated with the derivatives bearing this heterocyclic. Especially their importance in the cancer chemotherapy is unparallel. In our efforts to discover new chemical pharmacophore which may lead to formation of new anticancer agent. In the present study we have reported the synthesis of some new heterocyclic derivatives comprising substituted benzothiazole and 1,3,4-thiadiazole that linked by thiazole moiety. 2-Amino thiazoles are of interest because of their diverse biological activities and clinical applications. We have reported the new series of 2-Amino Thiazole analogues to target p56 lck(lymphocyte specific tyrosine kinase) inhibitors. Synthesized compounds were characterized and confirmed by IR, 1H-NMR and Mass spectral (MS) studies. For anticancer activity, all the selected compounds submitted to National Cancer Institute (NCI) for in vitro anticancer in which Compound 8(a) shown better anticancer activity. The MTT assay was carried out which showed compound 8(a) better anticancer agent than other summarized.
