Biological Activity
| ln Vitro | Cells contain hypotaurine and taurine in their cytoplasmic compartment. Taurine to hypotaurine has a ratio of roughly 50:1. Taurine's cytoplasmic concentration is about. 50 mm. Hypotaurine concentrations are lowered by 80% when opsonized zymosan is applied to resting neutrophils, converting them into breathing cells [1]. By inhibiting prolyl hydroxylase domain 2 competitively, hypotaurine triggers hypoxia signaling. As a result, glioma cell invasion and proliferation are increased and hypoxia signaling is activated [2]. |
| ln Vivo | In the spinal cord, hypotaurine has antinociceptive effects on mechanical, chemical, and thermal nociception. Hypotaurine decreased thermal hyperalgesia and mechanical allodynia in CCI rats. Pain that is neuropathic, inflammatory, and acute is suppressed by intrathecal hypotaurine. By stimulating spinal cord glycine neurons, hypotaurine can modify nociceptive physiological transmission [3]. |

| Additional Infomation |
Hypotaurine is an aminosulfinic acid comprising ethylamine having the sulfo group at the 2-position. It has a role as a metabolite, a human metabolite and a mouse metabolite. It is a conjugate acid of a hypotaurine(1-). It is a tautomer of a hypotaurine zwitterion. Hypotaurine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Hypotaurine has been reported in Homo sapiens, Bos taurus, and other organisms with data available. |
