Synthesis of new thiazolylmethoxyphenyl pyrimidines and antihyperglycemic evaluation of the pyrimidines, analogues isoxazolines and pyrazolines

New thiazolylmethoxyphenyl pyrimidines (7a–g) have been conveniently synthesized with better yields by cyclocondensing 3-(4-((2-phenylthiazol-4-yl)methoxy)phenyl)-1-(4-substituted phenyl)prop-2-en-1-ones (4a–g) with thiourea in aqueous emulsion of tetradecyltrimethylammonium bromide (TTAB) at 80 °C. Antihyperglycemic activity of the new thiazolylmethoxyphenyl pyrimidines (7a–d), thiazolylmethoxyphenyl pyrazolines (5a–d) and thiazolylmethoxyphenyl isoxazolines (6a–d) has been evaluated in sucrose loaded rat model. Among these compounds; 5a, 5c, 6b, 7c and 7d have displayed noticeable antihyperglycemic activity. Pyrimidines and pyrazolines have displayed better antihyperglycemic activity than the analogues isoxazolines.
