Lysophosphatidic acid (LPA) is a phospholipid that acts as an extracellular signaling molecule and activates the family of lysophosphatidic acid receptors (LPA 1-6 ). These G protein-coupled receptors (GPCRs) are broadly expressed and are particularly important in development as well as in the nervous, cardiovascular, reproductive, gastrointestinal, and pulmonary systems. Here, we report on a photoswitchable analogue of LPA, termed AzoLPA , which contains an azobenzene photoswitch embedded in the acyl chain. AzoLPA enables optical control of LPA receptor activation, shown through its ability to rapidly control LPA-evoked increases in intracellular Ca 2+ levels. AzoLPA shows greater activation of LPA receptors in its light-induced cis -form than its dark-adapted (or 460 nm light-induced) trans -form. AzoLPA enabled the optical control of neurite retraction through its activation of the LPA 2 receptor.
