Analgesic 4005. Antiinflammatoty 4016. Insecticidal 4027. Antibacterial 4038. Herbicidal 4043-N-Arylamino-1-(4,5,6,7-tetrahydro-thiazol-yl)-2-pyrazolines are found to beuseful as an antiinflammatory and allergy inhibitor agents. 405 K. Trena andZolzislaw 406 have tested 2-Pyrazolines on rats and observed comparatively goodresponse as hypoglycemic agents. Moreover, several pyrazolines have beenreported to possess antimicrobial activity 407 .
