产品介绍
Hypotaurine (2-aminoethanesulfinic acid) 是星形胶质细胞半胱氨酸生物合成牛磺酸的中间体,是甘氨酸受体的内源性抑制性氨基酸。

Animal experiment:

Rats: A radiant heat source is focused on the middle part of the rat’s tail. The time interval from the onset of the stimulus until the tail flick response is measured using a tail flick unit. The intensity of the radiant heat is adjusted to give a tail flick latency of 4–5 s before the administration of hypotaurine or saline. In the absence of a response, the stimulus is terminated after 15 s (cutoff) to prevent tissue damage. The effects of hypotaurine (100, 200, 400, and 600 μg) on thermal nociception are assessed repeatedly for 120 min post-injection[3].

产品描述

Hypotaurine (2-aminoethanesulfinic acid), an intermediate in taurine biosynthesis from cysteine in astrocytes, is an endogenous inhibitory amino acid of the glycine receptor.

Hypotaurine and taurine are found to reside within the cytosolic compartment of the cell. The ratio of taurine to hypotaurine is approx 50:1. The cytosolic concentration of taurine is approx. 50 mM. The concentration of hypotaurine decreases by 80% when resting neutrophils are converted into actively respiring cells by exposure to opsonized zymosan[1]. Hypotaurine activates hypoxia signaling through the competitive inhibition of prolyl hydroxylase domain-2. This leads to the activation of hypoxia signaling as well as to the enhancement of glioma cell proliferation and invasion[2].

Hypotaurine has antinociceptive effects on thermal, mechanical, and chemical nociception in the spinal cord. In CCI rats, hypotaurine alleviates mechanical allodynia and thermal hyperalgesia. Intrathecal hypotaurine suppresses acute, inflammatory, and neuropathic pain. Hypotaurine may regulate nociceptive transmission physiologically by activating glycinergic neurons in the spinal cord[3].
