Abstract: A chemiluminescent assay method and compositions are described which use a dialkyl-substituted dioxetane which is deprotected to trigger a chemiluminescent reaction. Chemiluminescent 1,2-dioxetane compounds substituted on the dioxetane ring with two nonspirofused alkyl groups which can be triggered by a reagent to generate light are disclosed. Dialkyl-substituted dioxetanes are useful for the detection of triggering agents including enzymes. The enzyme may be present alone or linked to a member of a specific binding pair in an immunoassay, DNA probe assay or other assay where the enzyme is bound to a reporter molecule.

Abstract: A method and compositions including a 1,2-dioxetane and a fluorescent compound is described. In particular, enzymatic triggering of a triggerable 1,2-dioxetane admixed with a surfactant and the fluorescent compound attached to a hydrocarbon to provide a co-surfactant in a micelle or other structure providing close association of these molecules is described. The method and compositions are useful in immunoassays and in DNA probes used for various purposes.

Abstract: Alkene precursors for preparing dialkyl-substituted dioxetanes. The dioxetanes are useful for the detection of triggering agents including enzymes.

Abstract: Stable, enzymatically triggered chemiluminescent 1,2-dioxetanes with improved water solubility are provided. Dioxetanes further substituted with two or more water-solubilizing groups disposed on the dioxetane structure provide superior performance by eliminating the problem of reagent carryover when used in assays performed on capsule chemistry analytical systems. Compositions comprising a dioxetane with two or more water-solubilizing groups, a non-polymeric cationic surfactant enhancer and optionally a fluorescer, for providing enhanced chemiluminescence are also provided.

Abstract: Novel light producing 1,2-dioxetanes are described of the formula ##STR1## wherein ArOX is an aryl ring substituted with an X oxy group and A are passive organic groups which allow the 1,2-dioxetane to produce light when triggered by removing X. X is a chemically labile group which is removed by an activating agent. The 1,2-dioxetane compounds can be triggered to produce light at room temperatures.

Abstract: Novel alkene intermediates useful in the preparation of 1,2-dioxetanes.

Abstract: 4-(3-beta-D-galactopyranosylphenyl)-4-methoxyspiro[1,2-dioxetane-3,2'-adama ntane] which is useful in various chemiluminescent assays.
