Abstract
Enzymatically cleavable chemiluminescent 1,2-dioxetane compounds capable of producing light energy when decomposed, substantially stable at room temperature before a bond by which an enzymatically cleavable labile substituent thereof is intentionally cleaved, are disclosed. These compounds can be represented by the formula: ##STR1## wherein: X and X.sup.1 each represent, individually, hydrogen, a hydroxyl group, a halo substituent, an unsubstituted lower alkyl group, a hydroxy (lower) alkyl group, a halo (lower) alkyl group, a phenyl group, a halophenyl group, an alkoxyphenyl group, a hydroxyalkoxy group, a cyano group or an amide group, with at least one of X and X.sup.1 being other than hydrogen; and R.sub.1 and R.sub.2, individually or together, represent an organic substituent that does not interfere with the production of light when the dioxetane compound is enzymatically cleaved and that satisfies the valence of the dioxetane compound's 4-carbon atom, with the provisos that if R.sub.1 and R.sub.2 represent individual substituents the R.sub.2 substituent is aromatic, heteroaromatic, or an unsaturated substituent in conjugation with an aromatic ring, and that at least one of R.…
