During that period, several types of bonds held them together. However, in the last two centuries these bonds have weakened due to the adoption of political principles and governing systems which are far from Islamic teachings. As a result, new problems have arisen, among them being the issue of ethnic minorities. Kurds are a victim of the new situation. They have been trying unsuccessfully for a century to achieve the same rights as other peoples in the Middle East. Their attempts and counter-actions by the states of this region are historically analyzed in this paper. Various approaches to resolve this issue are discussed along with the reasons for their failure.

On the other hand, thiazolo[3,2-a]pyrimidine-3-one 3 was coupled with aryldiazonium salts or condensed with isatin to afford compounds 4a-c or 5, respectively. Chemical structure of the target compounds was substantiated by IR, FT-IR, 1 H-, 13 C and DEPT-13 C NMR, MS as well as microanalyses. Moreover, the lipophilicity of the target compounds is expressed as Clog P. The antimicrobial screening of the test compounds 2a-x, 4a-c and 5 revealed moderate activity in comparison to reference drugs. Compounds 2a-c, 2e, 2o and 2v showed a gradual increase in their anti-inflammatory activity reaching its maximum at 5 h compared to indomethacin. Furthermore, the analgesic activity of compounds 2a-c, 2e, 2o and 2v revealed a maximum activity after 5 h of injection compared to aspirin and the LD 50 of compounds 2e and 2v was determined.

The (p, pi) reaction involves large momentum transfer ...
