The present disclosure describes compounds of the formula: (I), (II), (III), (IV), (V). The compounds described herein may be cyclooxygenase (COX) (e.g., cyclooxygenase 2 (COX2)) inhibitors. The compounds may be radiolabeled. The compounds (e.g., radiolabeled compounds) may be useful (e.g., as positron emission tomography (PET) imaging agents) for diagnosing a disease. The compounds may also be useful for treating or preventing a disease. The present disclosure also describes pharmaceutical compositions and kits including the compounds; and methods of using the compounds.
Differences in regioselectivity were observed during the SNAr reaction of amines with unsymmetrical 3,5-dichloropyrazines. This study revealed that when the 2-position of the pyrazine was occupied with an electron-withdrawing group (EWG), nucleophilic attack occurred preferentially at the 5-position. When the 2-position was substituted with an electron-donating group (EDG), nucleophilic attack occurred
