Novel compounds comprising a C—C double bond substituted at one carbon with two sulfur atom-containing groups are disclosed. The compounds are useful in methods and compositions for generating chemiluminescence rapidly by reaction with a peroxidase enzyme and a peroxide. The chemiluminescence thus produced can be used as a detectable signal in assays for peroxidase enzymes or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.
The present invention refers to compounds of formula (I) or a pharmaceutically acceptable salt thereof: Formula (I). These compounds have FFA4/GPR120 receptor (FFA4) agonistic properties. The invention refers also to pharmaceutical compositions comprising these compounds, chemical processes for preparing them and their use in the treatment or prophylaxis of diseases associated with FFA4 receptor activity in animals, in particular humans.

We have made a series of 4- and 5-aryl- and 4- and 5-heteroarylsalicylic acid derivatives with the objective of reducing gastric irritation and increasing potency. Here we describe a series of 4- and 5-heterocyclic salicylic acids and their antiinflammatory-analgesic potencies measured in comparison to aspirin. An improvement of the therapeutic index over aspirin of 100 was achieved; however, the heterocyclic

A method for enhancing chemiluminescence which uses a heterocyclic compound of the formula: ##STR1## wherein R.sub.1 is an oxygen or sulfur atom or an imino group optionally substituted by 4-hydroxyphenyl, and R.sub.2, R.sub.3 and R.sub.4 are a hydrogen or halogen atom, an optionally substituted hydrocarbon residue, a heterocyclic group or the like in a luminescence system.
